Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
Home Mycology Lab
Source Institutions
Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.
Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.
Onion DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
Gluep
Source Institutions
In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.
Separating a Mixture
Source Institutions
This activity was designed for blind learners, but all types of learners can explore means of physically separating a mixture using dissolving, filtration, and evaporation.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
Mirror-Tracing
Source Institutions
This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.
Air-filled (Pneumatic) Bone Experiments
Source Institutions
Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
All Mixed Up!: Separating Mixtures
Source Institutions
Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.
Dye Like A Natural
Source Institutions
In this activity, learners stain fabrics--on purpose!
Nutrients in an Estuary
Source Institutions
In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.
Foam Rocket
Source Institutions
In this activity, learners work in teams build and launch rubberband-powered foam rockets.
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.
