It's time to roll up those sleeves and get a little dirty in the second lesson of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil. First,...

Third graders examine soil samples and explore the what happens in each layer of the subsoil. They work in cooperative groups to create a scroll that shows what takes place in each layer, and discuss why much of the activity is in the...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

Young botanists examine the different parts of tress and then draw parallels between the functions of these parts and the function of parts of the human body. 

Students make predictions and analyze soil. In this soil properties lesson, students make predictions about soil properties for various soil samples. Students examine the types of soils and record their observations. Students analyze...

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Students study and classify soil. For this soil science lesson, students classify soil by texture and size and study soil horizons. Students label the soil types with their specific soil horizon and learn about permafrost. Students...

Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

Students reseach the different types of soil erosion and ways to control it in this series of activities.

Every year, more than 14 billion pounds of garbage is dumped into the oceans of the world, most of which is plastic and toxic to ocean life. Lesson 32 in the series of 36 focuses on environmental concerns, specifically pollution. Under...

Educate scholars on pollution—air, water, and land—with a series of lessons that begin with a thorough explanation of each type. Learners then take part in three activities to reinforce the importance of reducing pollution. They...

Young scholars explore the physical properties of rocks. They explore the three different types of rocks and are able to compare and contrast their different properties. Students simulate the creation of sedimentary rock, they also...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

Students determine which types of garbage are biodegradable and which are nonbiodegradable. They practice measuring skills, hypothesizing, taking data, and writing a lab report. Students observe the relative biodegradability of metal,...

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 investigate the growth of trees. In this tree growth lesson, students discover that trees make a ring each year they live. Students use new voabulary such as bark, phloem, and cambuim to talk about tree parts. Students create a...

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.

Fourth graders explore landscapes. In this landscape lesson, 4th graders investigate different elements of landscapes. Students design a visual presentation using photographs taken during a nature walk.

Students read information about George Washington Carver and outline the information. They are given peanuts in the shell, students examine them and eat them. Students discuss the following questions: Why did George Washington Carver...

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students are introduced to tree structure and use. They identify their special tree using all senses except sight. Students identify six different internal parts within a cross section of tree trunk (bark, phloem, xylem, cambium,...

Students read and discuss the information that they read on the "Kentucky Coal, Reclamation and Subsidence." They then answer questions in reference to the reading. Some questions that students answer are: What is reclamation?, Name...

Students conduct experiments to study the quality of water. They examine how pollutants get into and affect the water supply in this unit.

Middle schoolers create a model of an aquifer and describe how an aquifer works. They describe how running affects an aquifer and prepare a model presenting to local planners the important aspects of protecting recharge areas.
