Cloudy Globs: Can You Make a White Gel From Two Clear Liquids?
Source Institutions
Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.

Fill it to Capacity
Source Institutions
In this math lesson, learners rotate through six estimating and measuring centers. First, learners read the book, "Room for Ripley" by Stuart J.

The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

Solar Cooker
Source Institutions
Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

Real Glass Xylophone
Source Institutions
In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

NEWspaper: Make Your Own Paper
Source Institutions
Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.

Diaper Dissection
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

Growing Food From Scraps
Source Institutions
In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.
Soda Pop Can Hero Engine
Source Institutions
In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.

3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.

Suminagashi: Floating Ink Paper Marbling
Source Institutions
In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

Dissolving a Substance in Different Liquids
Source Institutions
In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

Pearlescent Pigments
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

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.
