Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

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.

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.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

This math challenge, played with two players or a whole group, engages your problem solving skills.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
