Learners discover how fish tagging is used by marine biologists and fisheries to estimate fish populations. Participating in a simulation, students use estimation to determine the whole population from a small number of items.

Students explore the concept of motion. In this hands-on physics lesson, students examine how the construction of baseballs and the temperature they are stored at affect their bounce.

Students apply estimation strategies for problem-solving purposes. They become familiar with one aspect of a marine biologist's work.

Students build their own boomerang. In this physics lesson, students trace the origin of this equipment. They practice throwing and catching them.

Students cut out the pattern of the Four-Wing Boomerang and trace it on to one half of the file folder. They practice throwing it.

Students work together to create a web of life. In groups, they put on nametags and form a circle. They toss the ball to a random person in the group and they make a connection between the person throwing the ball and the person...

Fourth graders participate in a game reflecting the solar system, stars, and rockets. They simulate how space invaders move and hit stars and rockets. They discuss how scientists study the stars and planets.

In this recognizing facts about the Great Horned Owl activity, students read fun facts, match illustrations with adaptations, sequence life cycle cards, and read what to do if they find an injured bird. Students solve 16 answers.

Students build a four-wing paper boomerang. In this aeronautics lesson, students construct a paper boomerang and identify the forces at work during flight.

For this reproduction worksheet, students identify the 5 major ways organisms reproduce asexually and list examples of organisms that reproduce in that manor. Then students complete 10 short answer questions.

First graders recognize that spiders are important natural predators. They work in small groups with simple field guides to identify as many of their spiders as they can.

Young scholars discover tidal pools.  For this oceanographic lesson, students observe the tides of the earth and the creatures that inhabit the intertidal zones.  Young scholars role-play the tidal zones by portraying...

Students study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson, students participate in classroom stations to learn about fresh water and salt water, cold...
