Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

A dripping faucet may be enough to drive you crazy, but it also teaches you a little about ratios. Presented with the volume of a sink and the rate the water is dripping, scholars must devise a plant to determine how long it will take...

Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...

Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

The Holocaust is the focus of this interactive poetry strategy. The classroom will be set-up to remind students of the Secret Annex, with a table, lamp, and various other props. Each participant will receive 3  Saltine crackers and...

Students conduct experiments to illustrate global warming. For this air pollution lesson, students first examine how a layer of greenhouse gasses might impact the earth's atmospheric temperature, then evaluate how the layer of gasses...

Students examine the tree species in Pennsylvania.  For this Pennsylvania tree lesson students use field guides to assist them in identifying tree species. 

Students recognize some forms of pollution. In this science lesson plan, students recognize and understand some of the devastating effects of the acid rains and other possible factors that are contrary to the pH balance of nature.

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
