Guess Who? The Periodic Table!

I developed this game as part of a “creativity in science teaching” assignment. Educational games are excellent ways of providing differentiated instruction in the classroom. At their best, they can hold a students’ attention far longer than a teacher can, allow for differentiated learning through visual, kinesthetic and interpersonal stimulation, increase motivation for learning through playful competition, and encourage oral communication, collaboration and peer teaching between players. Most importantly, they make learning fun.

Game Play
Guess Who? The Periodic Table! is played in the same way as the original Hasbro game Guess Who? The periodic table game cards are designed to be printed and used with the game trays provided with the original game.

At its core, Guess Who? is a modified game of “20 Questions” (see player rules provided with the game cards for details). Note that with either game card, students may ask any questions about an element’s properties (lustrous, flammable, metal, gas, etc.) but may not ask questions about an element’s location on the periodic table, as this would make the game too easy.

Game Card 1: The First 24 Elements
As the title suggests, this card includes only the first 24 elements, and is designed to encourage familiarity with the symbols for and physical and chemical properties of these elements (e.g., density, texture, combustibility, etc.), as mandated by the Ontario Grade 9 Science curriculum.

Students may need to refer to their notes or textbooks to help them formulate appropriate questions about the physical and chemical properties of the elements. Doing so will reinforce learning from lessons, labs and other activities and should be encouraged.

Game Card 2: The Elements and STSE
This game card expands student thinking about the elements beyond their properties to their historical, cultural, economic and environmental significance, and includes some of the lesser-known elements. Most of the information on this game card extends learning beyond the Ontario Grade 9 Science curriculum.

Variation
Though Guess Who? is designed as a two-player game, teachers may print a class set of game cards and provide one to each student, without the game trays. Students could then play in pairs or small groups, stroking out elements as they are eliminated through questioning. Laminated game cards could be reused: students could write on them with dry erase markers, wax crayons or grease pencils.

Skills encouraged
The original Guess Who? is a simple but effective game that encourages a variety of skills that are important to the Ontario science curriculum:
  • logical thinking
  • deductive reasoning
  • observation and visual discrimination
  • grouping
  • question formulation
  • listening and oral communication

In addition to promoting these skills, Guess Who? The Periodic Table! also encourages students to:
  • use vocabulary associated with the chemical elements and the periodic table (alkali metals, halogens, noble gases, etc.)
  • recognize elemental symbols (Fe, Cl, N, Na, etc.)
  • become familiar with the positions of elements and groups on the table
  • compare and contrast physical properties of different elements

Use in the classroom
Guess Who? The Periodic Table! can be used in the classroom in a variety of ways:
  • as part of a series of hands-on activity centres that allow students to explore scientific concepts and learning with partners or in small groups
  • as a group or partner activity to familiarize students with or consolidate learning of the periodic table and the properties of the first 20 elements (students will be able to self-assess their additional learning needs based on how easily they can formulate questions that get them closer to winning the game)
  • as a class activity to review learning about the chemical and physical properties of elements and the organization of the periodic table in Grade 9 Science
  • a class-wide diagnostic tool at the beginning of the Grade 10 Science chemistry unit to assess how well students remember what they learned in Grade 9
  • as a culminating activity, students could develop their own versions of Guess Who? incorporating physical and chemical properties of the elements. Student success at developing this variation would allow for assessment of overall learning about the properties of elements covered in class
  • as a tool to inspire greater depth and breadth of learning through independent study in gifted or advanced learners

The Ontario Science Curriculum and Guess Who? The Periodic Table
Guess Who? The Periodic Table! encourages thinking in each of the four categories of knowledge and skills identified in the achievement chart for the Ontario science curriculum:
  • Knowledge and understanding (through familiarity with chemical elements and the periodic table)
  • Thinking and investigation (through questioning and observing)
  • Communication (through oral communication, use of vocabulary and terminology)
  • Application (by making connections between science, technology, society, and the environment)
Contact me if you would like the complete Ontario Grade 9 Science curriculum fit.

Literacy connections
Guess Who? The Periodic Table can increase student proficiency at reading symbols used in chemistry, particularly the symbols for the elements themselves, as well as various laboratory and cultural symbols (toxicity, radioactivity, gas, etc.).

“The Elements and STSE” game card encourages scientific literacy through connections with etymology and mythology, and can be a way of piquing student interest in various elements and driving them to do further reading on various topics.

Extensions
For students looking for additional challenges, “The Elements and STSE” game card can be used to encourage further study on a variety of topics, including:
Students can also use the game cards as a model to create their own version of Guess Who? for other science units (e.g., cell organelles, ecosystems, living organisms, etc.).

The periodic table included with the game cards and instructions is Ptable.com's Dynamic Periodic Table. The Royal Society of Chemistry's Visual Elements Periodic Table is also an excellent resource.

If you use this activity with your students, let me know in the comments how it went!

Bridging the gap: 
Interdisciplinarity in high school sciences and humanities teaching



*This is a paper I wrote for my biology class last month. I considered revising it to make it more blog friendly, but at this point in my career I'm more interested in what practicing teachers think of teaching an integrated curriculum than in giving advice on how to do it, so I've decided to publish it as is. Comments always appreciated!

Introduction
“We can educate a large proportion of our better minds so that they are not ignorant of imaginative experience, both in the arts and in science, nor ignorant neither of the endowments of applied science, of the remediable suffering of most of their fellow humans, and of the responsibilities which, once they are seen, cannot be denied.”
C.P. Snow, 1959

More than 50 years after C.P. Snow's seminal “two cultures” lecture, in which he exposed the division between the humanities and sciences (Snow, 1959), the polarization between these broad domains continues. More recently, E. O. Wilson (1998) noted that intellectuals trained in the social sciences and humanities have difficulty understanding the how the natural sciences are relevant to social behaviour and policy, while natural scientists do not have the background knowledge to engage with social scientists. Even closely connected domains like environmental policy, ethics, social science and biology each have their own practitioners, language and modes of analysis (Wilson). The result, wrote Wilson, is confusion.

The failure of the disciplinary approach is particularly apparent when one examines multi-systemic issues like climate change. For decades, environmental scientists have been communicating about climate change with little effect on individual behaviour (Groffman et al., 2010). Part of the problem is that, traditionally, ecologists’ efforts to reach non-scientific audiences have been based solely on providing information without taking into account the ways in which people reach judgments (Groffman et al.). Yet decisions about environmental behaviour cannot be separated from the social networks that influence people, such as their values and political context (Groffman et al.). To motivate, enable and empower the public to act on climate change, scientists need to apply insights about these broader social issues and how people learn about science which requires an understanding of ongoing research in the social sciences, not just environmental science. (Groffman et al.).

There are hopeful signs that the humanities-science gap is being bridged, at least at the university level. For example, ecologists are now calling for communications training for university science students, and interdisciplinary degree programs have been proposed to develop professionals with a strong understanding of the relationship between science and society (Groffman et al., 2010). This training would enable graduates to communicate effectively with the public and the media.
Here in Ontario, one such program is the Environmental Visual Communications program offered jointly by Fleming College and the Royal Ontario Museum.Positioned at the convergence of science and art, the program blends visual communication (photography, videography and design) with strategic communication, marketing principles and science knowledge to communicate environmental messages for public education and engagement about conservation and stewardship (Fleming College, 2012).

Further afield, the University of British Columbia held a workshop in September of 2008 entitled “Integrating Science and the Humanities” to explore the promise and challenges of integration between the natural sciences and the humanities (University of British Columbia, 2008).
This type of interdisciplinary collaboration is essential if we are to address systemic, society-wide problems. Though promising, however, it should be happening earlier, at the secondary and elementary levels. This paper will focus on interdisciplinarity and curricular integration at the secondary level.

What’s wrong with the current model?
Wilson (1998) noted, “all tangible phenomena, from the birth of stars to the workings of social institutions, are based on material processes that are ultimately reducible, however long and tortuous the sequences, to the laws of physics.” Or, as Randall Monroe notes in the XKCD comic above, to the laws of mathematics. Either way, synthesis and integration are crucial to understanding the connections between the various disciplines.

In the current cellular model of teaching found in most high schools, disciplines are taught one at a time and independently of each other. Teachers are subject matter experts who can offer depth and breadth of content within their disciplines. This structure allows for deep exploration of the ways of thinking and specific skills particular to each field (Fogarty, 2009).

However, this model encourages students to compartmentalize their learning; humanities, sciences and arts are taught with little attempt to connect one discipline to the next, and students are left to make connections on their own (Fogarty, 2009).

Furthermore, overlapping concepts, skills and attitudes are not identified in the cellular model. While concepts and skills that appear across a variety of disciplines are clearly key areas for learning so a case can be made for learning them multiple times in different disciplinary contexts this repetition of learning creates more work for students, reduces the transfer of learning to novel situations, and can be tedious (Fogarty, 2009).

The isolation of the current curricular structure is is exacerbated by the system of prerequisites for university and college acceptance, which requires post-secondary-bound students to begin orienting towards their chosen domain in grade 11. The grade 11 course load of an Ontario student hoping to attend a high-ranking university for a highly competitive honours science program could very likely include:       
  • Mathematical Functions
  • Physics          
  • Chemistry
  • Biology
  • Earth Sciences
  • English
This leaves only two credits with which to explore interests in the humanities.

By Grade 12, this same student could be taking:
  • Physics
  • Chemistry
  • Biology
  • Advanced Functions
  • Calculus
  • English
Again, there would be room for only two additional courses.

By grade 11, students can have eliminated the humanities (with the exception of English) from their educational careers entirely before they have had an opportunity to explore and appreciate the connections between the disciplines.

This is problematic when one considers the concept of learning and understanding through semantic frames. A semantic frame is the collection of facts and related concepts unconsciously associated with and that are evoked by a particular word every word is associated with a semantic frame, and every individual has a unique set of semantic frames based on their own experiences (Lakoff, 2010). Because frames are communicated through language and visual imagery, one must have experience with the language of a particular discipline in order to build a semantic frame for it and to make sense of it (Lakoff).

Understanding issues that involve multiple systems requires frames for each system. In the case of climate change, this includes economics, energy, food, health, trade and security (Lakoff, 2010). Yet as a result of our cellular curriculum, most people don’t have the overall background system of frames needed for deep understanding (Lakoff). Education should give people a variety of frames through which to understand the world. Shunting students into either/or domains limits their capacity to make sense of the world outside of their own discipline.

How does integration improve things?
Interdisciplinarity creates a stronger overall background system of frames by examining multiple modes of thinking and developing a broad range of experiences. An interdisciplinary curriculum provides students with opportunities to investigate complex issues related to real-life experiences and with real-world applications (Fogarty, 2009). These connections to the real world are motivating for students, and deepen their engagement with the curriculum (Drake and Reid, 2010).

For example, Weissman (2004) describes a project where students, upon completing a unit on gravity, motion and states of matter, work with an artist to create clay and marble sculptures. When the sculptures are fired, the marbles will melt; the challenge for students is to sculpt the clay into forms that draw the melted marble into aesthetically pleasing patterns. Projects such as this allow students to engage with curricular content in real, practical ways. As a result, learning is more meaningful and personally relevant (Fogarty, 2009).

Integration can also draw students into disciplines they didn’t think they were interested in, and become a gateway to deeper learning (Fogarty, 2009). For example, a student with a keen interest in visual arts may choose to create a comic book biography about a scientist say, Nikola Tesla as a science project. As a result of the student’s personal commitment to the product (a comic book), the student will engage with the scientists’ history Tesla’s achievements, challenges and time period in a much more profound way than if they had been required to write an essay or memorize facts for a test. In addition, however, the student also deepens their understanding not only of the mechanics of graphic novelization, but of the potential power of personal narratives and visual storytelling in any discipline.

The above examples of interdisciplinary projects also deepen learning by engaging different types of intelligences (visual-spatial, verbal-linguistic, musical, mathematical, etc.) (Fogarty, 2009).
As the climate change example has shown, the environment isn’t just about the environment: it is deeply connected with many other issues and disciplines (Lakoff, 2010). An interdisciplinary approach is critical to fully understanding these other disciplines, and to synthesizing them into an understanding of climate change. A more connected, integrated curriculum that is organized into complex experiences that immerse students in multiple ways of learning and knowing enables students to think in global, systems terms.

How can teachers begin integrating the curriculum?
Because everybody sees different meanings in the world and different relationships between ideas, curriculum integration looks different for every teacher (Fogarty, 2009). As a result, there are a variety of approaches.

One tactic is to collaborate with other teachers to develop parallel sequencing of topics from different courses so that they coincide with one another (Fogarty, 2009). The cellular nature of the high school system makes integrated curriculum across courses more of a challenge at this level than at the elementary level, but it is possible. Courses can be sequenced so that teaching of related topics happens in parallel, allowing the lessons and activities of each class to support and enhance one another (Fogarty). For example, the study of optics in Grade 10 Science could be sequenced to coincide with an exploration of pinhole cameras in Grade 10 Visual Arts. Sequencing may be most effective in grades 9 and 10, when students’ class schedules are more predictable due to the higher proportion of required courses taken during these years.

Drake and Reid (2010) outline a backwards design approach as an effective way to plan an integrated curriculum within a single course. In this model, teachers scan the curriculum to determine what learning is most important (Drake and Reid). The more a specific learning or theme recurs, the more it is worthy, worldly, and widely influential (Fogarty, 2009). Teachers then choose an issue or theme through which to examine the key learnings. The unit culminates with a rich assessment task that involves multiple subjects, and daily lessons are structured around essential questions that lead to the culminating task.

Creating rich culminating tasks that integrate previously learned knowledge from a variety of disciplines provides subject richness, helps students deepen their understanding of what they already know, and allows for higher-order thinking, problem solving and decision making (Drake and Reid, 2010). A culminating task for Grade 11 Science, for example, could integrate information from any of Grade 9 or 10 Science, Math, Geography, History, English, and Physical and Health Education, since most students will already have completed all of these courses.

Conclusion
Though creating an integrated curriculum requires a fundamental change in practice (Drake and Reid, 2010), the increasing complexity of our world demands it. Integrated education will lead to more trust, collaboration and valuation of alternative methods between academic domains. These changes will be essential to the development of solutions to society’s biggest challenges.

The ever-growing accessibility of information makes interdisciplinary learning more important than ever for individuals, too. The world is in need of synthesizers people who can sift through information, think critically about it, and make wise choices. By developing individuals who can think around a wide variety of issues and topics, starting at any point and moving in any direction (Wilson, 1998), interdisciplinary education may be the best way to prepare students for for the future.
