Making Hypotheses

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate the creation of...

Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Step into the great outdoors and develop young scientists' skills of observation with a nature journaling lesson. Given a specific focus or goal, children practice making and recording observations of nature through written descriptions...

Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.

Have your class create their own compass. Using a needle, a container of water and a magnet, have learners explore magnetism. They will love making this useful tool and it will reinforce the fact that Earth has a magnetic field.

ROY-G-BIV make up the colors in a rainbow. Watch a video that explains the science behind rainbows, and how to create one at home.

Learners explore Earth science by conducting an energy experiment in class. In this windmill activity, students identify how wind has been used to pump water throughout history and the latest developments wind energy has produced....

Students explore space science by conducting a sun experiment in class. In this time telling lesson, students discuss how the sun sits in our sky at exact times each day and how astronomy is based on our perspective of the solar system....

Young scientists conduct a series of experiments to determine what type of soils produce the best results in roof-top gardens.
