Oxygen: What a Gas!
Eighth graders explain how oxygen reacts to other elements. They also explain why oxygen is a reactive substance, how it has weight, and how it reacts with other substances. They construct an experiment to relate their findings.
Curated OER
I Need Room to Breathe
Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.

Vibrations
Sixth graders use rubber bands, textbooks, pencils, rulers and yo-yos to experiment with the concept of vibrations. They observe changes in pitch according to the speed of vibrations and record their observations in a journal.
Curated OER
Energy Transfer
Students investigate the properties of heated air. They make predictions about what they think makes the wind blow on a worksheet, and conduct two experiments to demonstrate the properties of heated air. Students heat a bottle until a...

Hydraulics and Pneumatics
Seventh graders participate in an experiment using syringes. In this physics lesson students demonstrate the movement and principles of pneumatics and hydraulics.
Curated OER
It's All In The Surface: The Effects Of Color & Texture On The Ability Of A Surface To Absorb Solar Energy
Ninth graders examine how dark surfaces absorb more light than light surfaces. They perform an experiment that compares various surfaces abilities to absorb heat, then record and analyze the results.
Curated OER
Polymers and Crystals
Learners experiment with crystals and polymers and examine their roles in food science.
Curated OER
Soybeans in Space
Students work together to design an experiment that compares and contrasts differnet plant cultivation systems. In groups, they evaluate the results of the experiment to discover if the cultivation system could be used in space. They...

Grounded for Life
Second graders become familiar with the lives of penguins including their life cycles, habitats and basic needs. Students will experience the lives of penguins through stories and video.
Curated OER
What is Temperature?
Students study the effects of temperature and air expansion. In this temperature lesson, students discuss temperature and participate in a role play of low energy and high energy molecules. Students then discuss their activity and...

Physical Optics: The Wave Nature of Light
Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...
Curated OER
The Mystery of the Sponge
First graders observe while water is absorbed into a sponge. They experiment by putting a sponge on yardstick and watch while water dries and the weight changes.
Curated OER
Water and Ice
Students explore the states of water. In this water states activity, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...
