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.
NOTE: We substitute fishing weights for the tape and spoon used in VanCleave's activities because the fishing weights are designed to be tied to string (a spoon can slip out during spinning).
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.
