Born of Blood: Craft Stick Chromosomes
Source Institutions
In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.
Crazy Camouflage
Source Institutions
In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

Afterimage
Source Institutions
In this optics activity, learners investigate afterimages.
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.
Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
Cabbage Chemistry
Source Institutions
In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
