Use the choice board below to CHOOSE ONE WAY to demonstrate your knowledge of the following standard:
6-8.PS1.B.1 Develop and use a model to describe how the total number of atoms remains the same during a chemical reaction and thus mass is conserved.
Choice Board: Chemical Reactions and Conservation of Mass
| Assignment | Description |
|---|---|
| Video | Create a video explaining how the total number of atoms remains the same during a chemical reaction and how mass is conserved. See example video below. Please note that she used a physical change and not a chemical change. Your example needs to be a chemical change. |
| Poster | Design a poster that demonstrates the concept of conservation of mass in a chemical reaction. Include visuals and key explanations. |
| Comic Strip | Create a comic strip illustrating a chemical reaction and explaining how the total number of atoms remains constant and mass is conserved.*I can print some panels out of your, or you can use Canva to build them. https://www.canva.com/comic-strips/templates/ |
| 3-D Model | Build a 3-D model representing a chemical reaction. Explain how the number of atoms remains constant and mass is conserved through your model.*You can use any materials you have at school or home. I also have a few art supplies you could use. You will submit a picture of this for the assignment along with a written explanation paragraph. |
| Story | Write a story or narrative that describes a chemical reaction and incorporates the concept of conserving mass by explaining how the number of atoms remains unchanged. The story must also include pictures. |
| Free Idea | Come up with your own creative way to demonstrate the concept of conserving mass in a chemical reaction. Discuss your idea with the teacher before starting. |
No matter which idea you choose, it must demonstrate the Law of Conservation of Mass in relation to atoms in a chemical reaction.
