A new pair of science activities await you for Cycle 2 in 2019: VanCleave's "Expanding" and "In and Out". These materials are everything you'll need for a fun and interesting class of up to 10 student. Better still: pair these materials with our Cycle 2 Lesson Plans.
Package of 10 balloons
Wooden spools (2)
String (2 lengths)
Fishing weights (1-oz, 2-oz, and two 4-oz)
With the exception of the balloons, these materials can be rotated through one class at a time. If you have 2 science classes working at the same time, you'll need 2 kits.
