A Little Drop of Water: Cohesion
Source Institutions
Learners explore water's property of cohesion through two investigations.

Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Metal Reactions
Source Institutions
This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

Icy Investigations
Source Institutions
In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

Latent Prints
Source Institutions
In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

Recrystallization Test
Source Institutions
In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

How Do Viruses Recognize a Target Cell?
Source Institutions
This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr
Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Bee Talk
Source Institutions
In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

Magnetic Spinner & Compass
Source Institutions
Learners use shop tools and various materials to construct a magnetic spinner and a compass.

Heavy Lifting: Design Squad
Source Institutions
In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

Newton's Laws Demonstrations
Source Institutions
In this collection of demonstrations, learners explore Newton's Laws of Motion.

Mix and Match
Source Institutions
In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

Hull Engineering
Source Institutions
In this activity, learners explore how the hull shape impacts a ship's performance and stability.

Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.

Fan Cart
Source Institutions
If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

Building a Basic Series Circuit
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.
