Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

Relative Speed of Dinosaurs
Source Institutions
In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

Silly Putty Investigation
Source Institutions
In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Frijolitos
Source Institutions
Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.

Paper Airplanes
Source Institutions
In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

Quadratic Functions: Toothpicks and Transformations
Source Institutions
In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

Build a Raft
Source Institutions
In this activity, learners explore density and buoyancy as they design and construct rafts.

Weather Forecasting
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Super Spinners
Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

Fingerprint Identification
Source Institutions
In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Sweetly Balanced Equations
Source Institutions
In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

Bake Sale
Source Institutions
This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their school’s bake sale.
