Students discover whether their senses can detect unsafe drinking water. In the water activity lesson, students follow procedures to determine whether their bodies can detect contaminated water.

Students explore botany by participating in a calendar class activity. In this plant observation lesson, students examine a diagram of a Brassica plant and identify its anatomy before planting their own seeds and viewing the changes over...

Students identify the causes of hypothermia. In this biology lesson, students investigate the different types of heat transfer and heat loss. They discuss several practical measures to avoid hypothermia.

Young scholars comprehend the physical properties of pressure and Boyle's Law by designing a depth gauge. They construct a capillary depth gauge and calculate the calibrated depth marks of the capillary tube. They determine the margin of...

Pupils use foam packing pieces to represent molecular positioning inside the four layers of earth's atmosphere. This lesson help students visualize that molecules become thinner as one ascends higher in the atmosphere.

Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson plan, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Students identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also research the...

Students participate in a lab experiment in which they discover the need for so many blocks and tackles on sailing ships. In groups, they make and test their predictions and practice measuring objects in various units. They record and...

Students they imagine they are Galileo and try to duplicate Galileo's experiments and results.

Students examine the life of Sacagawea, the exceptional woman chosen to appear on the Golden Dollar, and write journal entries based on their research.

Students identify environmental challenges that can be solved throughout a product's life cycle. They experiment and examine how we can choose and use products in an environmentally responsible manner. Each student is also involved in...

Learners use an online interactive to launch a rocket from earth. They have control over the angle and thrust of the rocket to discover the relationship between the two.

Young scholars investigate the "wicking capacity " of fabric; that is how well various fabrics draw water "perspiration" away from the body and let it vent to the outside. They brainstorm possible protocols to measure, tabulate and...

Students will work in small groups, observing an ice cube and recording a description, the feel of the ice, and how it looks when put in another container. Students observe changes in the ice over 15 minute intervals, then freeze the...

Students investigate gravity.  In this weightless lesson plan students complete a lab activity about how a free fall might effect how one perceives gravity.

Students record observations about parts of plants including leaves, roots, stems, and flowers. They use Kid Pix to draw a picture of a plant and to label the parts of the plant.

Students investigate why a balloon flies in one direction as air escapes in the opposite direction, which helps them understand the nature of rockets and fireworks. Individually and in teams, students conduct research to create a...

Students differentiate distance and displacement. In this physics lesson, students use formulas to calculate for displacement. They draw vectors using the grid.

Students explore some of Earth's extreme environments and the possible dangers they present. They describe some of the potential dangers found in extreme environments around the world. Students discuss ways to deal with potential...

Students build and use a reflective solar cooker to cook marshmallows.

Students explore how the amount of sunlight and heat change in areas that are shaded.

Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Pupils examine how temperature is the measure of the average kinetic energy of the molecules of a substance.

Students examine rock strata for the distribution, deposition, and age of sedimentary rock. They describe rock types in a variety of outcrops and construct a regional stratigraphy.
