In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out. The activity includes a time and age recommendation, a materials list, step-by-step set up instructions, recommendations for things to try and to notice, tips for adults, learning and skills connections, a "what's going on" section, and a note about doing STEAM with kids. This activity requires two holes to be put in the container the learner is working with - an adult may need to assist with this.
