Source Institutions
This is a simple activity fully driven by imagination. Using materials from the home, toys, or items from nature, learners create their own world to play with.

From Polliwog to Frog
Source Institutions
In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.
The Jelly Bean Challenge
Source Institutions
In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

Skin, Scales and Skulls

Bat Echolocation Experiment
Source Institutions
In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.
