Dancing Raisins
Source Institutions
In this activity, learners will explore density and it's relationship with mass.
Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.
Anti-Sound Spring
Source Institutions
What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.
Take Out the Trash
Source Institutions
Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.
Crystal Painting
Source Institutions
In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.
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.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Why Does Food Spoil?
Source Institutions
In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.
Water Drop Exploration
Source Institutions
In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.
Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Snake Kite
Source Institutions
In this activity, learners will explore the physics of air by making a snake kite.
Does it Stick?
Source Institutions
In this activity, learners will observe magnetic properties and sort objects by them. This activity uses everyday items to teach learners about magnetic forces, poles and properties of magnets.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
All About Air
Source Institutions
In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.
Exploring the Universe: Orbiting Objects
Source Institutions
“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.
Stereo Sound
Source Institutions
We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.
Prepare for a Dock Shop Field Trip
Source Institutions
In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.
