In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

This lesson plan enables learners to explore the differences between weather and climate.

In this math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

In this activity, reuse two-liter bottles to create bowling pins. Learners practice math skills and develop a concept of verifying answers, while bowling and keeping score.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners follow simple directions to explore and create platonic solids.

Learners construct and launch paper helicopters.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.
