Students use cardboard and aluminum foil to construct a solar oven that concentrates enough sunlight to cook a hotdog. They review the history and use of solar energy in relation to the Olympics.

In this science worksheet, students calculate the size of different samples using the microscope as part of a formal lab assignment.

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Comparative anatomy prevails in the lesson exploring diversity among invertebrates. Biologists examine physical characteristics of an earthworm from phylum annelida and a meal worm from phylum insecta. They also inspect a cricket and a...

Study everything about plants! The 12-part series of lessons continues with an examination of many aspects of plants. Components of the laboratory activity address the growth and structure of plants by evaluating familiar plants. The...

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

Students predict the measurement of objects. In this measurement lesson plan, students estimate the measurements of objects in a lab. Students measure irregular objects and generate scientific observations.

Young scholars explore organisms and botany by utilizing microscopes. In this microscopic research lesson, students define many plant and organism related vocabulary terms such as conifers, moss and spores. Young scholars view spores and...

Students analyze lunar material using actual moon rocks that were brought back by Apollo astronauts. The teacher and student activity sheets are well-designed.

Fourth graders see how the flow of energy through an ecosystem made up of producers, consumers, and decomposers carries out the processes of life and that some energy dissipates as heat and is not recycled.

Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Students investigate chromatography. In this chromatography lesson plan, students investigate a lab set up for chromatography.

Students make butterfly eggs. In this butterfly lesson, students discuss the differences between butterfly eggs and other eggs. Students learn how butterflies lay their eggs and then make butterfly eggs out of clay.

High schoolers explore the basic building blocks of our planet.  In this minerals lesson high schoolers begin the process of forensics on the basis of investigation and drawing conclusions from observations. 

Young scholars discuss fossils. In this science activity, students simulate fossils within Earth's layers by using gummy fish and bread.

Students construct a simple refracting telescope. They calculate the magnification.

In this light and optics worksheet, students match the light and optics vocabulary with their definitions. Students match 21 words to their definitions.

In this science worksheet, students look for the words to fill in the crossword puzzle that is focused upon the concepts of light and optics.

Young scholars observe the life cycle of the common flour beetle and make observations of its life stages. They also design and implement an investigation on food preference for the beetle and record data over a period of several months....

In this biology lesson, students label and identify the different parts of a microscope. They complete 16 short answer questions about each part's function and complete 12 review questions in the end.

Students explore the world of the very small using a Flash plug-in Virtual Electron Microscope. They complete and discuss an activity in which unknown samples are placed under the computer simulated microscope to determine where the...

In this optics worksheet, students read about how light can reflect or refract and how lenses and mirrors work. Then students complete 13 matching, 27 fill in the blank, and 8 word problems.
