Students examine water. In this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...

Fifth graders investigate atoms. In this atom lesson, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Students investigate the characteristics of different soil samples. For this physical science lesson, students play the role of forensics solving a crime by matching soil from the suspect's shoes. They formulate a conclusion after...

Students investigate the strength of different adhesives. In this physical science activity, students compare the force needed to peel adhesive tapes from a surface. They analyze collected data and make a generalization.

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students examine a coastal ocean. In this physical science/earth science lesson, students generate a list of questions about how researchers study the ocean. In addition, students investigate, through research on the computer, to answer...

Middle schoolers design an experiment to investigate how objects with different masses fall. In this physics lesson, students predict how these objects will fall in a vacuum tube. They write a report explaining experimental results and...

Students identify animals in ecosystem depicted on 16th Century ceramic basin and classify them as herbivores, carnivores, or omnivores based on physical characteristics and prior knowledge, determine which life forms in ecosystem are...

Students will explain the Archimedes's Principle. In this lesson on plankton, students will describe three factors that can affect the buoyancy of plankton. This lesson contains extensive background information, extensions, and multiple...

Students explore light.  In this physical science light instructional activity, students display objects on a projection screen and investigate how light absorbs, refracts, transmits and reflects. Students discuss common features of...

Students study how matter changes from solids to liquids or liquids to solids. In this physical science lesson, students discuss heat energy and experiment with heat by changing a candle into a liquid using a hot plate.

Middle schoolers demonstrate how water flows by building a human watershed using themselves. For this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this...

Students build parachutes for chicken eggs. In this physics lesson, students describe the forces acting on a falling object. They predict which of the three parachute models they made has the best chance of keeping the egg intact after a...

High schoolers identify the different elements that belong to the Noble Gas family. In this chemistry lesson, students design a neon sign. They research how they are made and share their work with the class.

Students research about the chemical processes involved in cave formation. In this chemistry lesson, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

Students explore the unique properties of alkali metals. In this chemistry lesson, students create a mural of fireworks display after researching its different element components. They write a brief description about an alkali metal used...
