Echolocation Lab
Source Institutions
In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.
Runaway Runoff
Source Institutions
When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.
Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.
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,
Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
Starch Slime
Source Institutions
Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
Solving Dissolving
Source Institutions
The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.
Starch Breakdown
Source Institutions
Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.
"Boyle-ing" Water
Source Institutions
In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Forwards and Backwards
Source Institutions
In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).
Production of Hydrogen
Source Institutions
In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.
Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
Witches' Potion Demonstration
Source Institutions
In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.
Marine Ecosystems
Source Institutions
In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.
Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Flubber
Source Institutions
Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
