Chemical Reactions
This activity will help you meet these educational goals:
• You will develop a model to construct an explanation for how atoms and molecules combine to form new substances in
chemical reactions.
. You will make sense of problems and work to solve them.
. You will reason abstractly and quantitatively.
Directions
Read the instructions for this self-checked activity. Type in your response to each question, and check your answers. At the
end of the activity, write a brief evaluation of your work.
Activity
In this activity, you'll use a simulation to learn about chemical reactions between atoms and molecules. Get started by
following these steps:
1. Go to the simulation Balancing Chemical Equations e.
2. Click the simulation and select the introduction, Balance the three equations using the balance scale and graph tools.
3. When you've finished all three equations, go to the game and select level 2. Complete all five challenges.
Now use what you learned from the simulation to answer the following questions.
