Snail Observation Exercise
Young scholars are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.
Curated OER
The Same but Different Part II
Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

A Cloud In The Hand
Students investigate the scientific concept of forming clouds. The use simple materials to simulate the formation. This creates a powerful visual for students to make cognitive connections. They make observations and record them in a lab...
Curated OER
Build Your Own Sling Psychrometer
High schoolers construct a sling psychrometer and they measure the relative amount of humidity in the air. They create their own experiment on how to construct a sling psychrometer and how they are going to measure the relative humidity...
Curated OER
Which Sand Contains The Most Salt?
Students investigate the salinity levels of sand samples taken from several different sources. They conduct tests and observations to measure the current salt levels. They develop a hypothesis from the experiment to determine the factors...
Curated OER
Clouds in a Jar
Fifth graders create a cloud jar so that they can observe that clouds are made of tiny droplets of water. After observing the cloud jar, they record their observations on a worksheet in written form explaining that clouds are made of...
Curated OER
Tadpoles to Frogs!
Third graders observe the tadpoles/frogs and draw a picture in their journals every week to monitor its growth with 100% accuracy. They observe tadpoles/frogs and record at least two changes or the observations the tadpole undergoes...
Curated OER
Genes and Aging
Students explore genes and the way we age. They assemble a worm collection device called a Baermann Funnel. Students collect Caenorhabditis elegans or other active nematodes from local soil samples. They observe the appearance and...
