Students collect weed seeds from three varieties of weeds (knapweed, thistle, or toadflax, for example they may choose others in addition to the spotted knapweed.) They sterilize soil for thirty containers, plant seeds in sterile soil,...

In this forensic science lesson, students sketch bullet line fractures and complete 16 short answer questions on glass and soil evidence.

Young scholars explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...

Second graders grow a classroom garden that acts as a living laboratory for cross-curricular activities. In this classroom garden lesson, 2nd graders follow directions to build and plant a garden that is used to teach math, science, and...

Students compare the properties of rocks and relate these properties to their use. They perform a virtual experiment to describe and group rocks on the basis of their characteristics.

Students study urban runoff. They identify the urban runoff in a simulated area and determine peak flows using charted data. Finally, they discuss possible causes of the differences in flow rates.

Learners evaluate the relationship between rainfall and runoff of a small island for one year. In this rainfall vs. runoff lesson, students analyze the relationship between the rainfall and the runoff on Barro Colorado Island over a...

Students discuss reasons to plant trees and the best locations for cooling. They study two homes and identify types and locations of trees and determine the placement of the central air conditioners. The class plans a landscape design...

Students study bogs. They tour, collect physical, chemical, and biological data and analyze a pristine bog community. Using the data, they draw a map and a cross section of the bog.

Students explore tools. In this tool lesson, students see how tools and machines were invented to help people work easier. They see different types of simple machines such as wheel and axle, lever, and wedge. 

Students understand the definition of hydroponics. In this space hydroponics less, students simulate the experiment conducted in space. Students answer questions based on their experiment.

Young scholars model the soils layers using Oreo's. In this lesson students use their favorite food items to create a model of soil layers. A discovery lesson from a youth camp is adapted for classroom modeling and discussion of...

Students test the pH of soil samples they collected from the field trip. In this chemistry lesson, students differentiate acids and bases. They write a lab report about the experiment.

Students explore the physical properties of sand, soil, and rocks and sort, classify, compare, and contrast the materials found in the soil. The differences between the living and non-living parts of the soil is discussed.

Students complete an activity by looking and gathering data on plants and soils.

Young scholars develop an understanding of our planet as a system by designing a very-long-duration space mission in which the life-support system is patterned after that of earth.

This clever lesson combines elements of geography, art, literature, and storytelling. Pupils take a close look at the six geographical regions of Arkansas, and pay close attention to Crowley's Ridge - which is one of the six. In groups,...

Observing plant succession doesn't have to be a decade long process. A hands-on lesson has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil characteristics in...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors apprearing...

Students participate in an activity in which they identify properties of water, soil and rocks. They work together to identify different types of rocks. They ask questions to complete the lesson.

Fourth graders show the needs of plants met by soil. For this Science lesson, 4th graders detail the components of soil and determine which are living or once living and non-living. Students determine the needs of plant growth that are...

Fourth graders identify and examine the components that make up soil. Individually, they use a magnifying glass to identify the organic and inorganic material in their soil sample. To end the instructional activity, they record the...

Students complete experiments in which they test the amount of humus in soil samples. They record their data and discuss the results. They write a story about soils to end the lesson.
