Learners interpret archaeological strata using the law of superposition. They apply cross-dating to determine the age of other artifacts.

Students investigate the correct mix of material types for compost. In this composting lesson, students explore the correct amounts of different types of materials to create a compost heap. Students then create a compost heap.

Students explore the parts of plants and discover that plants need to grow. In this plant instructional activity, students discuss the parts of the plant and plant petunias. Students can share their plants with friends or families.

Young geologists utilize Moh's hardness scale to help them correctly sort and classify different types of rocks. This lesson has everything you need, including an excellent example of the Mohs' Hardness Test, to successfully implement...

The question posed for the class to consider; What would decay and what would not? They read the short passage on decomposition and microbes, then mark the items that would decay after a two-week period. A scientific investigation idea...

Students complete a variety of activities related to the physical characteristics of minerals. They classify and group candy, classify rocks and complete a Pet River Rock worksheet. Students try to guess which rock goes with each...

Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Students will explain the importance of soybeans. In this science lesson, students participate in making a "beanie baby" necklace. Additionally, students observe their soybeans for germination and growth for 7-10 days. Students record...

Students explore plant science by participating in a botany activity. In this seed growth lesson, students identify the necessary elements to ensure a plant grows well and prepare seeds for planting. Students plant their soaked seeds in...

Students identify parts of prairie plants. They sketch the plants indicating its adaptive parts and write brief descriptions of them. They present their findings to the class.

Students examine the importance of details in evidence gathering, as well as the relationship between chemistry, physics and biology.  In this forensics lesson plan students divide into groups and look at fingerprints and fill out...

Young scholars identify and interpret a variety of solid materials - cloth, wood, metal, plastic, paper, and rubber. After a period of free exploration, they then describe the properties of the objects and develop vocabulary in order to...

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

Young scholars observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle...

Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...

Fourth graders identify basic properties of minerals and rocks. They access websites and utilize worksheets imbedded in this lesson to further their understanding of rock classification.

Learners explore Halloween by examining pumpkins in class. In this pumpkin observation instructional activity, young scholars discuss the method in which pumpkins are grown and the time line it takes a pumpkin to grow from a seed....

Learners put items in a plastic bag and watch the effects of composting. While completing the experiment, students answer questions and ask permission to start their own compost pile at home.

Learners discover which properties of solids lend themselves to building a tower through hands on trial and error and observation of others as they are building. They write down the steps it took them to build the tower and label an...

By the end of this unit you should be able to: list the seven characteristics used to describe soils, to distinguish one soil from another soil, and to distinguish one soil layer from another soil layer; explain the impact of soil...

Students investigate soil porosity by building a model using the three main soil textures: sand, silt, and clay.

Have you ever played in dirt from your yard? You were actually playing with one of the most important natural resources on earth - soil. Watch a short video on soil and a second video showing the phases of plant development using...

For this guided inquiry students will specify soil types by using various methods of determining soil textures and analyze them with a soil triangle. This activity is a laboratory investigation where students gather data on soil...

Soil is the foundation of conventional on site wastewater treatment.The drainfields used with on site systems work because the soil around the trenches acts as a filter and removes organic matter, some of the nutrients present in...
