The children who came to our events learned chemistry with Fireworks in a Jar, Biology with mealworms, Physics with propellers, and engineering with mystery architecture. Fireworks in a Jar is any activity where kids put water in a jar and then place drops of food coloring in vegetable oil. Then they pour the vegetable oil with food coloring into the water, which creates an explosion inside the jar. This happens because food coloring does not dissolve in oil, but it does dissolve in water, so once the food coloring touches the water, it creates an explosion. Students were able to play with our mealworms at every event and learn which temperature mealworms thrive in. Mystery Architecture is an activity where children must create the tallest structure out of straws, plastic cups, popsicle sticks, tape, and pipe cleaners. This structure must be able to hold a ball and the children have 5 minutes to build their structure.
