Students select and collect soil samples from a variety of locations (schoolyard, home, etc.). They do this lab after an interest-generating discussion about "dirt" and microbes. Students make a dilution in sterile water, plate it on a...

Tenth graders define pH and use it to interpret amounts of hydrogen ions in a solution.  In this hydrogen lesson students read about acid rain, divide into groups and present their information to the class. 

Learners collect rocks, identify them, classify them, investigate their properties, and more. In this rocks lesson plan, students also experiment with soil and erosion and weather.

Learners view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

Fifth graders explore erosion and the different types of sediment.  In this erosion patterns lesson students complete an activity and divide into groups and conduct an experiment. 

First graders investigate soil, sand and silt. In this environment lesson, 1st graders discuss how changes occur in the environment and the effects of weather. Students perform their own investigation and record their predictions,...

Eighth graders study earthquakes.  In this earthquake lesson students research the Internet on earthquakes and plot earthquake locations. 

Students grow flowers in different soil mediums to determine the effect on flavor.  In this investigative lesson students study flowers, plant them and taste them to see how they differ in different potting soils. 

Fifth graders observe their plant experiments that they started in a previous lesson and examine the role of decomposers in the nitrogen cycle. Two weeks after they set up a worm terrarium, they analyze any changes they observe, and...

students identify questions about trees and plants to include their importance, parts, and systems. They list the things they know, want to know, and how they are going to study it.

Students investigate the cooling and heating of water. In this online science experiment lesson, students work in groups to make predictions regarding freezing and boiling points and then test those predictions as they complete the...

Students explain that when a beam of light is reflected from its surface, it changes direction. In this virtual science experiment lesson plan, students complete an activity that requires them to investigate how flat mirrors reflect...

Students experience a virtual quarry. In this science musical lesson plan, students understand how materials are quarried and manufactured from rocks, musically interpret a quarrying sequence with untuned musical instruments, and...

Students describe and compare common properties of various classroom materials. In this science/matter lesson, students observe common classroom items and the materials they are made of to complete a list of common properties.

Eighth graders study the nine soil factors to use in field study and to complete an exam. They learn the components and characteristics of soil.

Students examine the relationship between particle size and rate of water flow through soil. They collect soil samples, make predictions, conduct a water flow experiment, analyze the data, and answer conclusion questions.

Students are introduced to the on-farm nutrient cycle, which explains feed to manure, to soil, and back to the feed. They are introduced to the generation of runoff during rainstorms, and the contents of runoff water are more than water...

Students explore the process of decomposition. In this science lesson, students carve a pumpkin and observe as it decomposes. Students compare the changes to an uncarved pumpkin. Students write about the disappearing pumpkin.

Students explore the impact natural events have on the environment, specifically the wetlands. They view a video about the impact of Hurricane Katrina on the Mississippi Delta and answer discussion questions.

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

Students examine the connection between trees and erosion. In this erosion activity students experiment with the effects of rain on a hillside. Students investigate the number of trees and the amount of erosion.

Fourth graders investigate the process of water erosion. They observe the roots of a plant and discuss the concept of erosion. Next, in small groups they conduct an experiment to observe how water erodes soil on a stream table, and...

First graders describe what help seeds need to grow, including light, water, good soil, and warmth, observe and discuss what happens when seeds do not have help, and state similarities and differences among seed growth.

In this lesson plan, Summer Water & Sand Activity: Mud Pies and More, students investigate mud while playing and creating with it. Students understand mud, what it is, and how it is formed. Students develop their creativeness by...
