Gelatin Prism
Source Institutions
In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

Slime
Source Institutions
Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

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.

Build a Roller Coaster
Source Institutions
Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

Root Observations
Source Institutions
In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

Amphipods: More than Mud
Source Institutions
In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

Shake a Shrub
Source Institutions
This is an activity where learners will discover what types and how many insects live in their own backyard.

Family Math Activity: Measuring with Paper Clips and M&Ms
Source Institutions
In this activity, young learners and their caregivers use non-standard tools, like M&Ms and paper clips, to measure things around their home.

How to Test The Strength of Shapes
Source Institutions
In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

Beach Buckets
Source Institutions
In this activity, learners explore a bucket of sand and beach objects.

Amazing Air
Source Institutions
In this activity, learners construct a small "air cannon," and use its airflow to put out a candle (lit with the help of an adult).

Handwashing Laboratory Activities: Fingerprint Technique
Source Institutions
In this lab (Activity #1 on page), learners compare bacteria growth on two petri dishes containing nutrient agar: one that has been touched by a finger washed only with water and one that has been tou

Make Your Own Weather Station
Source Institutions
This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

Make a Water Cycle Wristband
Source Institutions
In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!

Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Odd or Even
Source Institutions
In this math activity, learners play a game and try to collect the most cards by guessing if the next number to appear will be odd or even.

Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
