Students discuss Hominid evolution through various websites and other resources. They examine online fossil skulls, discuss the use of tools by ancient man, and look for examples of sophisticated tools built by man.

Students analyze different habitats. In this habitat lesson, students evaluate what animals need in their habitats. Students participate in the game Habitat Hopscotch.

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

In this atoms worksheet, students review protons, neutrons, electrons, molecules, compounds, and ions. This worksheet has 10 fill in the blank and 3 problems to solve.

Students analyze gas chromatograms and suggest various applications for gas chromatography.

Fourth graders explore the many uses of corn-based products and the importance of water resources. They consider how biodegradable products help to keep water clean. They perform experiments to observe how corn pellets dissolve while...

Young scholars complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students create paper by adding a few small scraps of paper into the blender pitcher and adding just enough water to thoroughly soak paper.

Students compare and contrast the different types of alternative fuels. They create a concept map to understand their classification. They examine the properties of matter and energy as well.

Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

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.

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Young scholars calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Fourth graders create a salt relief map of the four regions of Virginia. They indentify land forms and bodies of water, and summarize how they made their project.

Learners write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.
