Burning Questions About a Candle
Source Institutions
In this activity, learners will observe a deceptively simple process: a burning candle.
Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
Shady Snakes

Shake and Break
Source Institutions
In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.
Canjo
Source Institutions
In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.
Catapult
Source Institutions
In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.
