Pringles Pinhole Camera
Source Institutions
An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.
Comet Cratering
Source Institutions
Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.
Light Maze
Source Institutions
In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.
What's So Special about Water: Surface Tension
Source Institutions
In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.
Bank It!
Source Institutions
This simple but open-ended math game introduces basic probability concepts using coins and dice. Players roll the dice and collect coins to match the number rolled.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Static Cling
Source Institutions
In this activity, learners investigate static electricity using everyday objects at four different stations.
Balloon Drive
Source Institutions
In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.
Salt Crystal Garden
Source Institutions
In this activity, learners will explore saturated solutions and discover how crystals form.
Crushing Test
Source Institutions
In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.
Liquid Crystals Interact with Light!
Source Institutions
In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.
Space Stations: Follow the Bouncing Ball!
Source Institutions
In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.
Solar System Bead Distance
Source Institutions
In this astronomy activity, learners create a model of the solar system using beads and string.
Milk Magic
Source Institutions
In this activity, learners experiment with how dish soap and fat interact by making a colorful swirl.
Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.
Mammal Flipbooks
Source Institutions
In this activity, learners explore mammal locomotion by constructing flipbooks.
Make An Impact
Source Institutions
In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.
Chromosome Models: Karyotyping
Source Institutions
This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos
