Plastic Rock

 

Physical Science, Experiment 6.1

Materials: 5 cups corn flour, 2.5 cups water, large plastic container, large spoon, 4 students

Hypothesis: I expect to find sticky goop on random surfaces throughout the classroom for the next several weeks.

Process: In the large plastic container, mix 5 cups of corn flour with 2.5 cups of water. Stir until mixture becomes hard. Let mixture sit until it becomes liquid. Apply pressure and watch the mixture harden.

Results and Observations: Although the assignment was only for Quinton, all the students got their hands dirty. They each left their own studies to test the experiment. They spent 30 minutes punching and scooping up their new creation. Instead of sticky goop, we were left with a crusty film all over the classroom.

Conclusions: The mess was well worth it….learning should be a little fun!
