Phase Changes
Source Institutions
Learners observe a sealed test tube containing a small amount of solid stearic acid.
Supercooled Water Drops
Source Institutions
In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
Ice Fishing
Source Institutions
In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
As The Stomach Churns
Source Institutions
In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
LEGO® Chemical Reactions
Source Institutions
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).
Pressing Pressure
Source Institutions
In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.
Twist and Spout
Source Institutions
In this activity, learners make their own "tornado" using two soda bottles and water.
Ping Pong Ball Shooter
Source Institutions
In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.
Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.
Forms of Carbon
Source Institutions
In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.
Jar Races
Source Institutions
In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.
Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
Molecules in Motion
Source Institutions
In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
Forces on the Human Molecule
Source Institutions
In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
Exploring How Robots Move
Source Institutions
In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.
