Mixtures and Solutions
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

Bird in the Cage
Source Institutions
In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

Pixel Tube
Source Institutions
In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.

Observing Different Microbes
Source Institutions
In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

Curious Contraptions
Source Institutions
In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

Creating Craters
Source Institutions
In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

Kid Moon: Splat!
Source Institutions
In this activity, learners model ancient lunar impacts using water balloons.

Pom Pom Potential
Source Institutions
In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

Crystal Gardens
Source Institutions
In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.

Water Quality and pH Levels in Aquatic Ecosystems
Source Institutions
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

Bee Hummer
Source Institutions
In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.
Mission Insignia
Source Institutions
In this science/art activity, learners create an insignia or emblem for a planet exploration mission.

Motor Effect
Source Institutions
In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

Hand Battery
Source Institutions
In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
