Hot! Hot! Hot!
Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....
Curated OER
Free Up the Ketchup!
Students, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)
Curated OER
Colored Clouds
Fourth graders, in groups, examine how particles in warm water move faster than particles in cold water.
Curated OER
Water 2: Disappearing Water
Students will observe the amount of water in an open container over time and also examine the amount of water in a closed container over time. They then will compare and contrast the sets.
Curated OER
What's the Matter? (Experiments)
Students observe a scientific discrepant event, and are then challenged to create experiments to solve the dilemma.
Curated OER
Permafrost: Permanently Frozen Ground
Students explore permafrost. In this 3 states of matter lesson, students identify characteristics of solids and liquids. Students observe water and soil melting and freezing at various temperatures. Students make...
Curated OER
Emulsion_ Compulsion
Students experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
Heat Absorption
Young scholars examine how heat moves from substance to another. In this heat absorption instructional activity students identify ways that heat is transferred and analyze data.
Curated OER
Critter? Growth
Students identify and use the elements of the scientific inquiry to solve problems. They explain concepts about the structure and properties of matter. Pupils write an explanation of polymers and how the characteristic of polymers...

Activity #8 Which State Are You In?
Middle schoolers define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...
Curated OER
Rain Drops
Students examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
Curated OER
Slip Slidin' Away
Students investigate mechanical weathering as a form of erosion. In this erosion lesson, students, define weathering and erosion before determining how the Earth's surface is in a constant state of change. They watch a video, access...
Messenger Education
Cooling with Sunshades
Messenger's sun shade measures 8 ft x 6 ft and will have temperatures reaching 700 degree Fahrenheit on the outside while maintaining a cool 70 degrees underneath. In the third activity of four, groups discuss the basic properties of...
