Curated OER
Weightlessness Demonstration
Students explore the concept that free-fall eliminates the local effects of gravity. They discuss what an Earth-orbiting spacecraft experience is like as well as the terminology of weightlessness. Their lab experiment commences.
Curated OER
Zigzag Seeds
Pupils observe the effects of gravity on seeds. Students place seeds in various orientations and record their growth to determine how gravity affects the seeds' growth.
Curated OER
Mass
Students participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.
Curated OER
Water and Ice
Students investigate how water goes from a solid to a liquid then back again. In this experimental lesson students conduct their own experiment and see how water changes form.
Curated OER
Space Ship Pilot
Pupils visualize the relation between acceleration and velocity in 2 dimensions. They are introduced to Newton's first law,and Newton's second law. Students work on an exploration activity where they condsider an example of a...
Curated OER
Water and Ice
Students participate in various air experiments to understand that air is all around us. In this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....
Cornell University
Alka-Seltzer Rockets
Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.
Curated OER
MASS
Students distinguish between weight and mass. They examine how in oscillations of a mass against an elastic spring--in the absence of gravity, or in horizontal motion--the length of the oscillation period is proportional to the square...
Curated OER
Capillary Action and Adhesion
Learners perform classroom experiments to observe adhesion. They perform a second experiment using sand, salt, water, and a heat lamp to observe the principle of capillary action. They also experiment with adhesion in plants.
Curated OER
Density and Mass
Students experiment to find which liquids are more dense. In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...
Curated OER
Tableau
Second graders view a video from United Streaming and design still frames of important parts of a story. In this story-telling from different cultures lesson, 2nd graders understand general vocabulary about performing. Students pose to...
Curated OER
Animals Up!
Students design and build a pedestal or platform that holds a toy animal. For this building lesson, students use knowledge from a prior lesson as they build a platform or pedestal for a toy animal using on index cards. They learn the...
Curated OER
Growing Up (And Around, and Down...) Exploring Plant Growth
Students build plant growing structures. In this plant growth lesson, students plant growth structures such as a garden tepee or a crawl through tunnel. They grow plants that are appropriate for the structure.
Curated OER
Build Your Own Parachute
Students study the basics of parachuting. For this flight and aerodynamics lesson students make a simple parachute and investigate different variables that can cause potential problems.
Curated OER
Picket Fence Free Fall
Students measure acceleration using a Picket Fence and a Photogate. In this physics lesson, students drop an object and measure the acceleration of the object free falling. They log their data using the TI.
Curated OER
Properties of Air
Students conduct investigations to demonstrate and learn that air takes up space, and puts pressure, or pushes, on everything around it. They conduct experiments to learn about feeling air pressure and measuring air pressure. Prior to...
Curated OER
How Things Fly
Learners explain basic principles of aeronautics such as gravity and lift. In this How Things Fly lesson, students visit the interactive, hands-on How Things Fly gallery at the Smithsonian. Learners perform three experiments that...
Curated OER
Solar System: Let's Take a Trip
Third graders consider outer space. For this introductory solar system lesson, 3rd graders complete a KWL chart and listen to the story The Magic School Bus: Lost in the Solar System, by Joanna Cole & Bruce Degen. They will...
Curated OER
Water and Ice
Students will work in small groups, observing an ice cube and recording a description, the feel of the ice, and how it looks when put in another container. Students observe changes in the ice over 15 minute intervals, then freeze the...
Curated OER
Our Universe: Always Moving, Always Changing
Students explore the main concepts of astronomy through the eleven lessons of this unit. The past, present, and future methods of studying the science are examined in this unit.
Curated OER
Hurricanes
Learners state and directly experience two laws of Physics (Law of Gravity, Law of Centrifugal Force) that affect weather. They explain the observations made when using the "hurricane machine" and relate them to other events and phenomenon.
Curated OER
WHAT HOLDS US TO EARTH?
Students they imagine they are Galileo and try to duplicate Galileo's experiments and results.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
