Water Engineering
Source Institutions
In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

Mystery Tubes
Source Institutions
Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

Flower Power
Source Institutions
In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

Coding Algorithms
Source Institutions
In this activity, learners will code an algorithm to make it through a maze.

Learning the Land
Source Institutions
In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

Observing Earthworm Locomotion
Source Institutions
In this activity, learners collect worms and then observe how they move.

Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.

Fossil Rocks
Source Institutions
In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

All Mixed Up!
Source Institutions
In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

Gas Producing Micro-Reaction
Source Institutions
In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

Exploring A Hydrogel
Source Institutions
In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Create Your Own Decoupage
Source Institutions
In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.

Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

Production of Oxygen
Source Institutions
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

Concentrate!
Source Institutions
In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

Make a UV Detector
Source Institutions
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.
