Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

Sidewalk Chalk
Source Institutions
In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.

Melting Ice
Source Institutions
In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

Light Soda
Source Institutions
In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

Static Friction Prediction
Source Institutions
In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

Vectoring: Steering a Plane
Source Institutions
In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

Pipeline Challenge
Source Institutions
In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

Tiny Geyser Models
Source Institutions
In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.
Stability of Egg White Foams
Source Institutions
In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.
Tsunami: Waves of Destruction
Source Institutions
In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

Rubber Band Racers
Source Institutions
In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

Do a Spacewalk!
Source Institutions
In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.

Drinking Straw Oboe
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

Breathing Yeasties
Source Institutions
In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

Electric Gelatin
Source Institutions
In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.
