Exploring A Hydrogel
Source Institutions
In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

Speedboat
Source Institutions
In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

Lego Mania
Source Institutions
In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

Uplifting Force: Buoyancy & Density
Source Institutions
In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

Production of Oxygen
Source Institutions
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

New Sense about Cents
Source Institutions
In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

Cleaning Water with Dirt
Source Institutions
In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
Periodic Pegboard
Source Institutions
In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.

Production of Hydrogen
Source Institutions
In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.

Curie Point
Source Institutions
In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

Combustion
Source Institutions
In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

Round & Round
Source Institutions
In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

Moving On Up: Capillary Action II
Source Institutions
Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.
