Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Leaf Rubbings
Source Institutions
When was the last time you took a really close look at a leaf? In this activity, learners will use leaves and simple materials to make colorful leaf rubbings.
Wash Away Germs
Source Institutions
Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.
Mitten Challenge
Source Institutions
In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
What am I?
Source Institutions
In this activity, learners examine nanoscale structures of common things.
Exploring Tools: Mitten Challenge
Source Institutions
In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.
Balloon Kebabs
Source Institutions
In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon
Fireworks in a Glass
Source Institutions
In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.
