Students are focused on the big question: What makes a population grow and how could that growth stop? They use these concepts to help answer the big question: carry capacity, density dependent v. density, independent factors, predation...

Students take a crushed rock and sort the remains of the rock minerals into different categories based on the different properties. In this sorting lesson plan, students learn what makes up a rock and how to sort something into categories.

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Students learn about demographic population pyramids. They then design and fictitious nation and draw its population pyramid.

Students experiment by creating an oil spill and trying a number of clean up methods. They determine which methods are the least costly and most effective. They role play as an environmental engineer and as an oil company owner who must...

Learners research the impact that human activity had on Pennsylvania's water supply over time. In this water quality lesson plan, students research, discuss, and write about how Pennsylvania's water quality has been affected and what...

Pupils have discussions and complete activities about the pacific salmon life cycle and marine parasites. In this salmon lesson plan, students complete activities such as observing sea lice, playing a tag game, and a board game.

Students test different objects such as dominoes, marshmallows, slides, and more to test their force, motion, gravity, friction, and the concept of matter. In this force and motion lesson plan, students understand that the force an...

Students explore the concept of finding the composition of seawater.  In this finding the composition of seawater instructional activity, students make a saturated salt water solution.  Students discuss why there is variation...

Eighth graders identify and explain what Bernoulli's Principle is and draw diagrams to incorporate Pascal. They also perform simple calculations of density, buoyancy, and fluid pressure. Finally, 8th graders describe fluid pressure in...

Fourth graders study the geography and population distribution of various places on earth. They utilize actual satellite images of the night sky (lights showing heavily around area of dense population) to study and make observations...

A fascinating lesson on states of matter is here for your young scientists. Dry ice is used to challenge learners preconceived notions about how solids work. They discover all sorts of interesting facts about states of matter from...

Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.

Students explore many of the basic properties of matter including atoms, ions, elements, molecules, and density. The class explores an interactive flash-animated Web site to answer questions and clarify misconceptions they might have had...

Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

Learners view macroinvertebrates, or discuss previous collection activity. They graph data on macroinvertebrates in the Hudson River. Students discuss the relationship between habitat, environmental changes, and invertebrate diversity or...

Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

Second graders study force and what it does.  In this motion lesson students complete a demonstration on force and gravity and share their ideas. 

Tenth graders navigate and use the online Atlas of Canada. They explain the cause and effect relationship between human settlement and the natural environment and wildlife species. They utilize a worksheet imbedded in this plan.

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  In this water lesson students work in groups and complete several activities. 

Learners investigate cartograms in order to explore the different countries on Earth. In this world geography lesson, students use the Internet to analyze data on different cartograms. Learners compare data, such as population density,...

Young scholars create their own balance to determine a difference in the weight (and composition) of cents made in different years.

Students explore Earth's biosphere. For this biosphere lesson, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.
