Learners examine the descriptive science dealing with the surface of Earth, its division into continents and countries, climate, natural resources, inhabitants and industries of the various divisions and analyze the political geography...

Students (with a partner) draw and describe a leaf in its natural setting, and then re-find leaves drawn and described by classmates. The point is to have them start to think about observations in science, what to put in a field...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Students become familiar with body changes during puberty.  In this stages of human development lesson, students review the stages of development from 1-5.  Students read an article called I'm Growing but Am I Normal? and...

Students define a word from the natural disaster list, find a location in the world where this type of disaster has occurred and discuss what they have identified. They design a crossword puzzle of natural disaster words or check a...

Students take on the role of an Ocean Adventures expedition volunteer member and are charged with protecting three species of sharks from danger in order to defend the balance of nature in the ecosystem. They play an online game which...

Students examine the evidence that scientists have used to support the existence of global warming and the greenhouse effect. How the concepts have been developed and evaluated form the focus of this lesson.

Students participate in a culminating activity for a unit on Energy and Simple Machines. They are challenged to incorporate simple machines in to a complex mechanical system. While designing and testing their machine they will also...

In this physics worksheet, students investigate Newton's Three Laws. In this multiple choice, matching, and short answer worksheet, student answer eleven questions.

Learners discover every pendulum has a natural vibration cycle that depends on its length.  In this physical science lesson, students participate in an experiment that shows the natural vibration frequency of two pendulums is the...

Students examine the characteristics of a tornado. They practice using new vocabulary and participate in a question and answer session. They use the internet to gather more specific information.

Students consider the adaptation of life forms through natural selection to fill various niches and accommodate changing environmental conditions. They select an ecosystem and conduct research to provide as much detailed information as...

Third graders study the habits and habitats of ants. They research the use of technology as a valuable investigation tool and access other web sites for future research projects. The students make successful decisions while playing SimAnt.

Students participate in an after school program that promotes communications skills, hypothesizing, exploring, recording of data, leadership roles and making comparisons. They explore the world of insects, where they come from, how they...

Students understand what physical adaptations are and how they help an animal to survive. In this adaptations lesson, students research four animals and then make an original animal that has adaptations to make them survive.

Students study the work and accomplishment of Galileo. In this physics activity, students calculate the period of a pendulum's using a mathematical equation. They explain the different factors affecting its period.

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Students identify the major watersheds of Pennsylvania. In this forestry lesson, students learn what a watershed is and are assigned one of the major watersheds of Pennsylvania. Groups then need to determine the boundaries of the...

Young scholars investigate the properties of insulators by attempting to keep a cup of water from freezing, and once it is frozen, to keep it from melting. They conduct the experiment, record and analyze the results, and answer...

Students complete a worksheet while viewing a film about sharks. They examine the reasons for overfishing of the oceans. They identify predator-prey relationships as well.

Third graders construct a three-dimensional model of a flowering plant. They examine the major plant parts and their basic functions. They demonstrate an understanding of the similarities and differences in the physical...

For this ecology vocabulary exercise:  wetlands worksheet, students read the definitions of 8 words, then categorize a species found in a wetland in their region.  This page has numerous links to helpful web resources.

Young scholars investigate magnetic permeability and saturation. In this physics instructional activity, students explain how current carrying wire coils create magnetic forces. They interpret normal magnetization curves.
