Butterflies and Moths: Camouflage
Source Institutions
In this activity, learners make a camouflaged butterfly to hide outside for others to find.

Discovery Time: Bugs
Source Institutions
In this activity, young learners (2 years and up) explore the world of insects and other "bugs" by Making a "bug hotel" with recycled objects.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Basking Basics
Source Institutions
In this activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.

Slippery Coqui Eggs
Source Institutions
In this activity, multiple learners will use a game with ballloons to learn about coqui frog behavior.

Pollinator Bath
Source Institutions
In this activity, learners will build a design and build a place for pollinators to drink from.
