How do "instant" cold packs get cold when they are stored at room temperature, unlike a regular ice pack which must be stored in the freezer? In this lesson plan, students will explore several endothermic and exothermic reactions, and use their observations to choose the chemical reaction that best fits the design constraints for their own chemical cold pack.

In this lesson, students will employ the enzymatic decomposition reaction of hydrogen peroxide to investigate how chemical reactions are affected by enzymes and different substrate concentrations. Students will be challenged to control the rate of the reaction by adjusting the amount of substrate and thus changing the catalase activity. Foam production, created by the enzymatic breakdown of hydrogen peroxide into water and oxygen, will function as a proxy for the reaction rate. Based on their… Read more

When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids.… Read more

Teach your students how temperature affects chemical reaction rates in this highly visual experiment! Students will investigate color change during the reaction of food color with bleach, and measure the reaction times using Google's Science Journal app. Read more

How does surface area affect the speed of a chemical reaction? Let your students find out in this sizzling lesson plan! In this project, they will explore this correlation by crushing Alka-Seltzer® tablets into different sized particles and measuring how long it takes for them to dissolve in water. Read more

There are many different ways to make slime. In this lesson plan, your students will use the engineering design process to design their own slime product. They will need to decide on the desired properties for their slime and then experiment to find the best recipe. Read more

Teach your students how to make plastic out of milk in this hands-on lesson plan! You will conduct a simple milk-transforming experiment to explore how plastics can be derived from a natural resource such as milk. Students will perform their own experiments and can even create a product from their resulting organic casein polymer. Read more

In this fun chemistry lesson, students will explore chemical reactions by mixing pineapple juice and milk. Students will observe whether the properties of milk change when it is mixed with pineapple juice, as well as how they change. They will then infer from their results whether a chemical reaction happened. In the process, they will not only learn about chemical reactions but also discover the importance of enzymes and their role in the human body. Read more
