Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.

In this porosity and permeability activity, students experiment with different types of soils such as sand, gravel, pebbled and rocks. They put each soil type in a beaker and pour water in being sure to measure the amount of water they...

Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Students examine pieces of sheet music and identify context, purpose, and perspective with regard to the political, social, and economic conditions existing at that time. They create a cover illustrating a topic of the Progressive Era.

Young scholars create a rainstick from recycled materials and begin learning about the "nature" of the rainforest.

Students determine the center of mass of two irregularly shaped objects, determine when the center of mass is inside or outside the boundaries of the object, determine when and/or why an object is stable, balanced, unstable or unbalanced.

Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Students explain the physical properties of matter. They, in groups, perform a variety of experiments, each demonstrating a different property of matter. A very nice, hands-on lesson plan!

Students experiment with solubility and bonding.

Students explore coral communities. They explore a coral polyp and build a coral head.

Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Middle schoolers design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great instructional activity on buoyancy!

Students perform an experiment which simulates what happens inside an internal combustion engine. They explain how the chemical reaction they witnessed is similar to what happens inside the car engine.

Fourth graders identify the attribute of volume of an object. Units of measurement are reviewed and utilized in this lesson.

Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Students compare and contrast photosynthesis and chemosynthesis as processes that provide energy to biological communities. They investigate the energy content of hydrocarbons used in coral communities.

Fifth graders, in groups, complete two activities in which various substances are combined, resulting in a very different substances. They discuss reactants and products and chemical reactions.

Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Students examine how an aquifer operates. They discuss the implications of the groundwater becoming contaminated. They work together to create an aquifer model to observe the connection between surface water and groundwater.

Students investigate through role play how decisions by watermen, recreational fisherpeople, and lawmakers influence and are influenced by economics and the abundance or scarcity of fish and shellfish stocks. They consider social,...

Students design a closed system to test the relationships between plants and animals. They monitor abiotic fluctuations within this living system by using a chemical test kit. They observe how living organisms respond to fluctuations in...

Students identify features that make an automobile practical for a cross-country trip and then design a 1903 era auto using lessons learned from Horatio's journey.

High schoolers are able to analyze gravity as an universal force. They are able to demonstrate ways that simple machines can change force. Students are able to determine how the force of friction retards motion. They are able to...

Students conduct an experiment in which they extract the greatest number of grams of caffeine from four bags of tea. They conduct Internet research, conduct the experiment, and record their observations and data.
