Science - 4th Grade
Lesson Plans
Standard 3
Students will understand the basic properties of rocks, the processes involved in the formation of soils, and the needs of plants provided by soil.
Objective 3
Observe the basic components of soil and relate the components to plant growth.
-
A Recipe for Soil
Students make soil using local materials and compare plant growth in natural and student-made soil.
-
NHMU: How Are Soils Classified?
Students will learn to list the three texture groups in which soils are classified. They will also learn to classify a soil sample as sandy, silty, or clay soil.
-
S-O-I-L Soil
At the end of this activity students should know that plants need nutrients to grow, those nutrients come from the soil, and nutrients can be added to soil to help plants grow better.
-
Sand, Clay and Humus
Soil is composed of living, nonliving, and once living components.
Students discover these materials as they get their hands dirty in a bucket of
soil. Students then study the differences between humus, sand, and clay. They
will observe these samples dry, wet, and in settling tubes. This is a great introduction lesson and covers Object 3 A and B extremely well.
-
Soil Ingredients
Soil ingredients are sorted into organic materials and rock sediments.
