Robot Body Language
Source Institutions
In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Far-Out Corners
Source Institutions
Are there boxes, is this an illusion, or is this real life Q-bert? Illusions are always fun to build especially when you can build them.

Cool Trees
Source Institutions
This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.
The Bent Pencil
Source Institutions
In this optics activity, learners explore how light bends and affects what we see.

The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Natural Selection in Protected and Unprotected Populations
Source Institutions
In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.

Look Into Infinity
Source Institutions
Learners use two mirrors to explore how images of images of images can repeat forever.

Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

Leaf Me Alone
Source Institutions
In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

The Stroop Effect
Source Institutions
In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

Food Chains and Webs
Source Institutions
In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

Yummy Gummy Double Helix
Source Institutions
In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

Memory Solitaire
Source Institutions
In this online game, learners practice memory recall. They are shown a collage of pictures for two minutes, then have to write down everything they remember and check how they did.
Fossil Fuels: Facing the Issues
Source Institutions
Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

Decomposition Column
Source Institutions
In this activity, learners turn empty 2-liter bottles into a see-through compost container.

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.
