Curated OER
Sea Water Freeze
Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
Ice Cream
Young scholars create ice cream in a bag and snow ice cream to study the effects of freezing on foods. In this ice cream lesson, students understand the effects of freezing on cells.
Curated OER
Ice Floats
Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.
Curated OER
Build Your Own Hovercraft
Students construct a hovercraft following specific procedures. In this technology lesson plan, students explain the physics principles behind hovercraft. They compare and contrast this machine with the aircraft.
Curated OER
Simple Machines
Students explore the concepts of force and effort by observing simple machines. In this physics lesson, students attempt to sharpen a pencil without any help, bite into an orange with their lips curled over their teeth, and other...
Curated OER
Heat Discrepancies
Students answer the question, "Why do Eskimos build houses out of ice to keep warm. Since heat goes from hot to cold, don¿¿¿t the ice walls take away the warmth inside the house?" They explain how snow or ice can actually be insulators.
Curated OER
Hovercraft Racers!
Students gain first-hand experience on how friction affects motion. They build a hovercraft using air from a balloon to levitate a craft made from a compact disk (CD), learning that a bed of air under an object significantly reduces the...
Curated OER
The Magic School Bus Plays Ball
Learners learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students work in small groups to find how movement changes when there is more - and less - friction.
Curated OER
Sleet and Hail Have Their Own Seasons
Second graders explain the definition of hail and sleet. In this precipitation lesson, 2nd graders discuss when hail and sleet fall and the results of hail falling.
Curated OER
Introduction to Friction
Students study the properties of the frictional force between two surfaces in contact. They inspect various phenomena in nature where friction plays an important role and demonstrate
Curated OER
Landforms in a Tub
Fifth graders use common household items to build landforms and simulate weathering and erosion.
Curated OER
Ocean Currents and Sea Surface Temperature
Students use satellite data to explore sea surface temperature. They explore the relationship between the rotation of the Earth, the path of ocean current and air pressure centers. After studying maps of sea surface temperature and ocean...
Curated OER
The Great Heat Escape
Students observe a demonstration on the role of thermal conductivity in heat transfer. In this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances. Lesson...

Cycles, Systems, and Webs
Fourth graders review the parts of the plant and their functions. In this plant lesson plan, 4th graders recognize that plants must transfer energy to make food. Students understand the interdependence of organisms in an ecosystem.

The Digestive System
Fourth graders simulate how the digestive system works. In this hands-on simulation, 4th graders complete six group activities that help students visualize how our body breaks down food into nutrients.
Curated OER
"States of Matter"
Students investigate the different states of matter by experimenting in class. In this matter lesson, students participate in a lab activity moving from one station to the next creating different formations of matter. Students view the...
