A Spray Spree

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes. During the experiment, learners compare how the diameter of the nozzles affect how far the water sprays. The activity webpage includes a fun how-to video for learners and educators.
