In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

In this activity, learners confront their perceptions of gravity in the solar system.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.
