In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.
Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
Cabbage Juice Indicator: Test the pH of household products
Source Institutions
Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.
Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.
ZOOM Glue
