Great use of Numbers to scaffold students' work with the lab! Thanks for sharing this with us!

Experimental Design Lab: What amount of vinegar/amount of baking soda/size of plastic bottle will yield the largest balloon circumference?
Previous our first lab following experimental design fundamentals has been an uphill battle on rollerskates. Our high school freshmen biology team took on the objectives below, transforming the first PDF into an amazing Numbers document. Groups were assigned one of 3 variables to test. The final PDF is the cards we assign each lab group.
Objective #1: Design an experiment to determine the ideal conditions for producing the largest circumference balloon. You will use vinegar and baking soda (chemical reaction) to create gas to fill the balloon.
Objective #2: Create your own experiment using the terms and procedures we have discussed in class.

Thank you for sharing this! I have an 8th grade science investigations class that is going to LOVE working with these resources and idea.

Great idea. Wonder if students could go further and do a slow-motion video of the results?
