After identifying the properties of their substance, students will explain why those properties make the substance useful to us. This helps students understand why we even care about properties in the first place! Finally, they’ll communicate their understanding by creating a colorful brochure about their substance, its properties, and its uses. What will the students learn and do? Students will: • identify the uses of a substance of their choice • practice identifying physical and chemical properties of the substance • explain why those properties make the substance useful • create a brochure about their substance to communicate their learning Perks of this lesson • • • • • • • Fun and engaging for students Students enjoy choosing their own substance—gives them a sense of ownership Great opportunity for teacher to identify misconceptions Provides organic teaching opportunities when students get their research logs checked off Checking for understanding is built into the activity Artistic and creative students have a chance to utilize their skills Super fun to grade! Short ’n’ Simple Game Plan Students will: 1. Sign up for a substance to research 2. Research the physical and chemical properties of the substance, and fill out a research log as they find information 3. Get their research log checked off by the teacher 4. Create a colorful brochure about their substance using the information they collected on the research log Detailed Game Plan Before the activity This activity should be done when students already have an idea of many of the different types of physical and chemical properties that substances have. The brochure will need to be printed front/back. Make sure to line things up the correct way, otherwise the back will be upside down! Signing up for a substance I suggest giving students a list of substances to choose from (see attached list). If you’d like, you can offer that they come up with an idea of their own, but make sure to approve it first. You might want to pass out a few hard copies of substance ideas so the students can look over them before they sign up. Students should choose their top 3 choices before lining up to tell the teacher the substance they want to research, since the chances that their first choice will be taken are pretty high. Note: • Most foods are really tricky, but based on the student, you might approve them. Examples of foods you might want to avoid: cheese, milk, eggs, ketchup • Other foods work great, especially if they are a pure substance. For example: salt, sugar I like to write under a document camera or project a spreadsheet and type names in as students sign up for their substances. This allows the rest of the class to see which substances have already been taken while they stand in line, waiting to sign up. Research & Research Log Before building their brochure, students will research the substance they chose and fill out their research log. Note: In the bottom five boxes of the research log, students should simply describe what they are going to draw in each picture box on their brochure, not actually draw the picture on their research log. Students really struggle with the chemical properties part of this assignment. Remind them that a “non” property is also a property. For example, steel has the chemical property of being nonflammable. Encourage them to think through some of the “non” properties, such as non-reactive with water, non-corrosive, oxidization-resistant, etc. If the students have taken notes, you can ask them to refer to their notes to get ideas for properties they may not have thought of. Students also struggle with the “why these properties are useful” section. I often use the following kind of discussion to help them out: • Teacher: Why do we build skyscrapers with steel instead of peanut butter? • Student: Because it’s hard. • Teacher: Good! Steel has the property of being hard, so it doesn’t squish or compress like peanut butter. Let me ask you this: glass is a substance that is also hard, so why don’t we build skyscrapers with beams made of glass? • Student: Because glass breaks. • Teacher: That’s right. Do you remember the name of the property that means that a substance breaks easily? • Student: …Brittle? • Teacher: Yep! So, glass is brittle. That is a property we DON’T want in a beam for building sky scrapers. How is steel different from glass? • Student: It doesn’t break easily. • Teacher: Right. So, steel has a property of being “not brittle,” or we could say that it’s “strong.” We’ve figured out two properties of steel that make it useful for us—what are they? • Student: It’s hard and strong. When researching, students will try to find sites that clearly tell them all the properties of their substance. The chances of them finding a site like that are pretty slim, especially if the substance is a common one, like sugar. If students are struggling to find information about properties of their substance, encourage them to do a search on a page using ctrl-f and then typing in a particular property (e.g. “flammable”). Also, note that some sites define chemical properties differently—for example, some sites call the melting point of a substance a chemical property. Below are some websites that students have found useful in the past: • rsc.org • pubchem.gov • chemicool.com • chemicalbook.com • chemistry.about.com • Wikipedia.com Brochure Have students get their research log checked off with you before they begin on their brochure. This prevents them from making big mistakes on their final product that are difficult to fix. It also allows a great opportunity to identify misconceptions and guide students to “update” their understanding. Make sure to be clear in your expectations regarding the appearance of the brochure. I tell my students: “I want it to be beautiful, colorful, and legible.” Optional Extension If you’d like, you can have the students read one another’s brochures!
