Build your own Barometer! In this activity, you'll create a simple barometer to observe changes in air pressure and predict weather patterns. This experiment demonstrates how air pressure impacts water levels as the weather changes. By setting up a water-filled cup with an inverted plastic bottle, you'll mark the initial water level and watch how …
Build a Telescope! Design your own lens and parabolic mirror from simple materials and watch light refract or reflect onto a target, just as happens in actual telescopes. The activity can scale with the group or audience size: A big bowl or reflective surface will focus light well enough that an entire auditorium can see …
Electrical engineering encouragement! Learn how electricity moves through a circuit while designing an LED greeting card.
Invisible Extinguisher A balloon is used to capture the carbon dioxide produced by a baking soda & vinegar reaction in a water bottle. Because carbon dioxide is denser than air, it can be carefully transferred to a container and then “poured” over a candle, acting as an invisible extinguisher.
