Students investigate what causes the heat on Earth.  In this Earth heating instructional activity, students experiment with different heat sources and determine where the Earth gathers the most heat.  Students explore...

Fourth graders conduct investigations to test different types of soil from different regions of Texas. They make comparisons and identify the characteristics of the soil. The end product of the inquiry is a student report.

Students propose and perform an experiment using the scientific method. The purpose of the experiment is to discern some earth materials or combinations of earth materials that best increases the pH of "acid rain". From the results of...

Fourth graders complete a variety of experiments to meet science goals.  In this life sciences instructional activity, 4th graders make yogurt, discover the attraction of opposite charges in electricity, learn the effects of...

Students identify and explain that remote sensing can detect changes on the Earth's surface that occur over time, and name at least three: urbanization, deforestation, and succession. They select a global change issue to investigate and...

Students explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...

Students create an all-natural water filtration system. In this lesson plan on natural water filtration, students build upon prior knowledge to build a filtration unit made of plants, soils, sand, pebbles and rocks that can purify...

Students are able to describe earth processes (e.g., rusting, weathering, erosion) that have affected selected physical features in students, neighborhoods. They are able to identify various earth structures (e.g., mountains, faults,...

Students gain knowledge about the impact of drought in agriculture. They investigate soil types, water flow, and various erosion conditions which occur during a drought and see how farming practices changed after the 1930's.

Fifth graders explore the causes of earthquakes and the various types of fault lines through a variety of hands-on demonstrations using prepared cakes. They record their observations in their science journals.

Second graders compare and contrast animate and inanimate objects. In this environmental science lesson plan, 2nd graders create simple food webs. They observe their environment and create a collage about it.

Students investigate equilibrium in erosion and deposition by predicting effects of moving water on soil; modeling an erosion simulation; observing results of a test; inferring causes and effects, and hypothesizing about erosion variables.

Students study four types of soil and predict which one worms would use for their habitat. They observe worms in each type of soil and monitor their activity. They create class charts highlighting their discoveries.

In this crossword puzzle worksheet, students read the 25 clues about Earth Day. Students then complete the crossword puzzle about Earth Day.

Aristotle explained the idea of spontaneous generation, a concept which lasted almost 2,000 years before scientists proved it wrong. Scholars learn about the history of our understanding of the origins of life. They read examples of...

Water wizards write short answers and fill in the blanks about Earth's surface water and groundwater. They also identify the condition of the soil in a diagram. Use these two worksheets as a reading comprehension assignment if your...

Students investigate the 3 states of matter. In this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

Students engage in a lesson in which volcanoes be explored and examined. After watching a video, students create volcanoes out of clay.

Sixth graders explain how soil and plants effect contaminated water in nature.  In this filtration instructional activity, 6th graders work in groups to test biofiltration units. Students determine which biofiltration units work...

Students examine various soil samples in groups. Using the samples, they identify the characteristics of them and calculate percolation and infiltration rates. They use this information to discover why some species can survive in one...

Students analyze the relationship between soil moisture and its effect on soil temperature.

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...

In the sixth instructional activity in a series of 21, scholars use NASA data to graph and interpret albedo seasonally and over the course of multiple years. This allows learners to compare albedo trends to changes in sea ice with...

What is an alien's favorite game? All-star baseball! Scholars start defining living and non-living. Then, they conduct experiments to research if life exists, keeping in mind that life could be in many forms, not just human.
