Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.
Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
Gelatin Prism
Source Institutions
In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.
Slime
Source Institutions
Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.
Build a Roller Coaster
Source Institutions
Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.
Benham's Disk
Source Institutions
In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.
Reflecting on Diffraction
Source Institutions
With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.
Amazing Air
Source Institutions
In this activity, learners construct a small "air cannon," and use its airflow to put out a candle (lit with the help of an adult).
Self-Assembly Game
Source Institutions
This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
Exploring Black Holes and Gravity
Source Institutions
This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
Flubber: Make a polymer!
Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
Sticky Situation
Source Institutions
In this activity, learners separate the protein from milk and and use it to make their own glue.
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
Cohesion Coin
Source Institutions
In this activity about the property of water (page 6 of the PDF), learners use a coin to demonstrate cohesion between water molecules, exploring the molecular forces that allow water molecules to "
