Odors Aloft
Source Institutions
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
The Three Basic States (Phases) of Matter
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta
Floating Dry Erase Creations
Source Institutions
In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.
Air, It's Really There
Source Institutions
This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.
Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Gas Model
Source Institutions
This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.
Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.
It's a Gas!
Source Institutions
In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.
Air Cannon
Source Institutions
In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.
Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.
Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
Daffy Density
Source Institutions
In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.
What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.
Hot Stuff!
Source Institutions
In this activity, learners discover that sand is the major ingredient in glass.
Starch Slime
Source Institutions
Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
Conservation of Mass
Source Institutions
This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
As Light as Air
Source Institutions
Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.
Sublimation Bubbles
Source Institutions
"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
