Collaboratively, students partake in a hands-on activity in which they build models of a watershed. Each group member draws an elevation map—a bird's eye view—of their model and predicts how water will flow from the high to low points....

Students explore weight by building a spring scale and observing how it responds to objects with different masses. Each team of students can make their own spring scale by following steps which are specifically outlined in the plan. As...

First graders explore, analyze, document and study weather and the water cycle. They observe the weather and begin a weather journal. Each student interacts with the concepts of evaporation, condensation and precipitation, clouds,...

Students observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution instructional activity, students work in groups with stream trays that have different substrates. They...

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students observe the melting of ice. For this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Learners observe an online activity where they see some solids dissolving and some not dissolving. In this dissolving lesson plan, students learn which solids will dissolve, melt, and which won't. They will also see which effects are...

Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.

Students view demonstrations that illustrate the surface tension of water. In this properties of water lesson, students observe demonstrations that show how water exhibits surface tension. They explain how the demonstration shows surface...

Students study why corn is a biodegradable, renewable resource.  In this ethanol instructional activity students build models and observe a chemical reaction.

Learners explore erosion. In this science lesson plan, students build an island and observe the effects of erosion on the island. Learners discuss freshwater ecosystems in Hawaii.

Eighth graders review the history of weather forecasting. In this earth science lesson, 8th graders identify the different tools used in forecasting weather. They explain why it's important to know the weather.

Students observe oxidation reaction in the lab using copper pennies. In this chemistry lesson, students examine a $1 dollar bill and record their observations. They explain how to identify counterfeit money using the iodine test.

Students examine porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the information to understand how environmental engineers decide on the...

Students demonstrate their ability to distinguish between fact and fiction. Students identify the features of weather-related adages and proverbs. After reviewing several weather adages, students explain whether they are based in fact.

Students read and interpret the information from a barograph from a major winter storm. This task assesses students' abilities to interpret and analyze graphs, construct data tables and graphs, generalize, infer, apply knowledge of...

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

Third graders participate in a case study and use their problem solving skills to address the solution to a given situation. They consider how to survive in a foreign country, make economic decisions, and determine wise decisions for...

In this biology worksheet, 9th graders identify which seed color is dominant in the given chart and explain why it is. Then they create a Punnett square showing the alleles of the parent plants and first generation of offspring.

Learners explain how heat is used to generate and produce electricity.  In this energy lesson students complete several activities that show them about the different fuels used for heating. 

Students study La Chatelier's principle and identify how carbon dioxide may affect pH.  In this coral instructional activity students complete a worksheet on pH and observe a lab.

Fourth graders define cold and warm fronts, explain how they are formed and they ways that they affect the weather.

Fourth graders investigate the attraction between two different charges to explain the concept of lightning in a thunderstorm.
