In this Chemthink tutorial, you will explore chemical reactions and take a short quiz. Topics include:
- counting reactant and product atoms
- learning how atoms rearrange in reactions
- balancing chemical equations
Thank you so much to Mr. Charles Sprandal for making this wonderful tutorial!

I am going to try this activity out with my Chemistry students. I would be happy to donate if this does get positive feedback from them. Love the idea!

A couple questions. How do I open the tutorial and problem set? Is there anything that goes with the notes that has the answers?

Mike,
Great questions!
1. Students have direct access to the tutorials. As a teacher, you will need to log in in “Guest Mode” to see them.
2. The associated worksheets were created by teachers who were willing to share their work, but it will be up to each teacher to come up with an appropriate key for their own class.

This still doesn’t work on my students’ Chromebooks. 🙁 I love your sims.

Sorry about that! It is still on the list for HTML5 conversion. The current version should work on a flash-enabled computer.

Is this simulation going to be updated to HTML. Loved using it and now that we have no school would be great for introducing the conservation of mass.

Updated! This is the last of them!
4 years + 2 months + 2 days from when I started. I feel like I just finished my dissertation.

Chris, on the balancing scale during the tutorial and during the quiz, some of these are bouncing back off when trying to balance. It worked the first time I went through the tutorial but then when I got to the quiz question like this, it kept bouncing items off the other side when you would bring down the correct number of molecules. It did it again when going back to the tutorial under the just the one that required you to move it yourself. I tried. under Chrome and Firefox and got same results. Not sure why it worked first time and then quit working.

Hi Doug,
I am using physics colliders for the molecules to keep them spaced apart so you can count the atoms more easily. The trick is to drop them onto the existing molecules from above.

EDIT – I’m working on a new interaction now where the drop happens automatically as soon as you overlap the sensor. This will make it extremely difficult for you to accidentally push existing molecules off of the platform.

The interaction should be fixed. Please give it a try and let me know!
