Students have the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They describe gravity as a universal force that pulls everything toward the center of the earth....

In this tree-ring dating activity, students use activity sheets to determine a tree's age and to observe changes in climate from the tree-rings. Students investigate how archaeologists use tree rings to date evidence and they answer 5...

Seventh graders research about the climate and weather in different biome types. In this biology lesson, 7th graders create a brochure of their chosen biome using Microsoft Publisher. They present their work in class.

Students describe motion by the use of adding vectors. They identify the difference between the x and y components of vector quantities. Students are given the Paper Bridge Building handout and the instructions as to where to perform...

Students study soil and its composition. In this soil composition activity, students study examples of soil during several days of aeration. Students summarize their data, organize it, and must be able to explain their findings.

Learners perform an experiment using brown paper bags to determine which foods have oil in them. This task assesses student's abilities to make simple observations and inferences from them.

Students make a circuit on a mystery card. They then use an electrical tester to determine where electricity flows between circles on the card. They will connect wires, bulbs, and a battery to form an electrical tester.

Students make observations about Mystery Boxes that their teacher has made up and describes the motion of the object inside the box and hypothesizes it's shape based on their observations.

Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.

Young scholars sort organisms and objects into groups according to their parts and describe how the groups are formed.They identify body parts of animals from puzzle pieces, assemble the puzzle, and name the animal.

Learners create imaginary animals by assembling pictures of body parts from pictures of real animals. This is one of three linked tasks. The others are "Who's Parts Do I Have?" and "Animals Piece by Piece."

Students investigate the effect of different container materials on heat transfer; draws a conclusion about the best insulator; and applies concept to a new, seemingly quite different problem.

Learners test their knowledge of electrical conductors and circuits by constructing an electric tester and using it to determine where electricity flows between circles on a mystery card.

Students draw a picture of animal tracks a scientist might find after they read a story about a fox chasing a rabbit. They make up a key to represent the foxes' tracks and the rabbit's tracks.

Students explore an arctic, temperate, and tropical environment and then decide what people need in each environment to help them live comfortably and what their lives would be like.

Learners make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental instructional activity, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of...

Young scholars explore circuit boards. They determine that a complete circuit is needed to light the bulbs, experiment with the boards to develop strategies for finding where the hidden connections are, and develop strategies that can be...

Eleventh graders work in groups and investigate how force determines the speed and distance then they view the video, "Math Vantage #7: What's Your Angle?." They are given a real life problem to solve using speed, ramps, angle, incline...

Students investigate the history of fighter kites and build their own.  In this aeronautics lesson, students discover how other countries utilize fighter kites and where they originated.  Students create their own fighter kites...

Students research the basic concepts of heart health and disease and become an expert in an area as it relates to the heart and circulatory system. They prepare a multimedia presentation of their findings.

Fourth graders observe, plan, research, and create a field guide for the trees that are in their schoolyard. In this trees lesson plan, 4th graders make careful observations of what they see around their school and create a guide.

Third graders make a ballon rocket to study the relationship between the force applied to an object and the resulting motion.

High schoolers are able to analyze practices that affect the use, availabiltiy, and management of natural resources. They are able to show that the forces of friction retards motion. Students investigate electricity and magnetism as...
