Rising Water!
Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...
Curated OER
Properties of Matter
Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...
Curated OER
A Comparison of Land and Water Temperature
Students use the NASA website's Live Access Server to create a graph of surface temperature at two locations on earth. They analyze the data and then answer specific questions provided in this lesson. They also examine and compare the...
Curated OER
The Great Ocean Conveyor
Young scholars investigate water density. In this water density instructional activity, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.
Curated OER
Greenhouse Gas Lab
Students compare the ability of a sample of carbon dioxide gas to
absorb thermal energy compared to a sample of air. They build a visual representation of the greenhouse effect to illustrate the heat-absorption of
atmospheric carbon...
Discovery Education
Cushion It!
Sugar cubes, collide! Groups design protection systems using bubble wrap to protect sugar cubes from being destroyed by falling batteries in the STEM lesson. They consider how the experiment relates to collisions in real-world...
Curated OER
A Comparison of Land and Water Temperature
Young scholars examine NASA satellite observations of surface temperature and investigate the seasonal changes of land and water temperature.
Curated OER
Simplicity of Electricity
Students examine how to make an electrical circuit. They listen to a teacher led discussion, design a switch to control a circuit, and construct a signaling device.
Curated OER
Sports Helmets and Impact Testing of Polymers
Students examine the importance of good quality safety gear. In this investigative instructional activity, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets....
Curated OER
Compact Fluorescent Lamp Experiments
Students conduct a series of experiment on incandescent and fluorescent bulbs. In this physics instructional activity, students explain how they operate. They compare the efficiency and power rating of both bulbs.
Curated OER
Evaporation and Condensation
Young scholars explore how temperature affects the processes of evaporation and condensation.
Curated OER
Hot Air Balloon
Students view a video and discuss the mechanics of a hot air balloon. They, in groups, construct a functioning hot air balloon.
Curated OER
Biodiesel Combustion and Its Influences in NOx Emissions
Tenth graders evaluate the physical mechanisms that cause a change in NOx emissions. In this combustion lesson, 10th graders participate in a research project. Students create a presentation of their findings.
Curated OER
Evaporation and Condensation
Learners explore how temperature effects the processes of evaporation and condensation and how the air may be polluted by the evaporation of certain compounds. For this temperature lesson students complete a lab and a worksheet.
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Young scholars explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
