Students experiment to show the components that dictate centripetal force in an object. They observe how the object moves in a circular path around a central point.

Students observe examples of gravity, friction, and force on the playground. They then experiment and participate in a variety of activities in centers back in the classroom.

Pupils examine the concepts of ecosystems and interdependence. They construct block pyramids to demonstrate interdependence, and map off an area to observe and identify animals. They create food chain mobiles and play a web of life game.

Students examine climatic effects on ecosystems. They plant tomatoes and observe the differences in plant growth with differences in light. They create picture collages of plants, animals, and insects found in each climate of the U.S.

First graders predict, observe and record strategies to overcome them using discussions, role play, and charts. Over a three or four day period, they examine obstacles that humans and insects encounter.

Students observe and explore the characteristics of light.

Young scholars participate in an online lesson making and recording observations of magnets. They determine that magnets attract some metals but not others and that other materials are not attracted to magnets.

Third graders adopt a deciduous tree in September, and begin regular observations of their tree. They create a timeline to show how leaves change color and conduct a science experiment to illustrate color change.
