Students observe how plants recycle themselves, and discuss different types of propagation.

Students examine porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the information to understand how environmental engineers decide on the...

Students examine several types of plants. In this plant lesson, students complete activities that require them to identify types of plants, chart plant anatomy, and explain plant propagation.

Third graders identify various types of landforms of the United States. They discuss earth movements that produce geologic structures and landforms and define cycle as it relates to rocks and soil. They demonstrate the processes forming...

Pupils are introduced to the concept of glaciers. They discover how glaciers move and what types of landforms are formed by glaciers.

Students discover the types and amounts of particulate matter found in the air. They collect particulates using a Petri dish coated with Vaseline then classify and count the collection under a stereoscope.

Students investigate peanuts. For this science lesson, students explore the properties of the peanut and shell. Students burn a peanut to observe the peanut oil. Students taste test different types of peanut butter.

Students collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

Students investigate the concept of groundwater that includes aquifers, groundwater flow, and the water table. They participate in activities using a flow demonstration model. Its use engages all types of learners because of its hands on...

Fifth graders, after brainstorming why conservation of resources is important, distinguish between renewable and non-renewable resources. They make a list of different types of natural resources on the board and then sort them into two...

Fourth graders discover how the processes of erosion and weathering alter the physical characteristics of the environment. In a student log,they record the various types of erosion and list ways to prevent it. Using clear, plastic...

Middle schoolers use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution lesson, students work in groups with stream trays that have different substrates. They write a...

In this gravity worksheet, 8th graders complete 4 different questions related to defining gravity. First, they identify the various types of mass movement that is described in each. Then, students explain what each of the 4 types of...

Students investigate the relationships between protozoa, algae and monera in freshwater, shoreline soil, and reindeer rumen. They publish reports of their findings.

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

Students identify the types of natural resources. They explain the difference between weather and climate. They practice using a rain gauge and reading a thermometer.

Young scholars listen to the story "The Great Kapok" then discuss characteristics of the rain forest. They make several different types of rain forest animals from paper plates (ex. sloth, tigers, monkeys etc) and design costumes for a...

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

In this science worksheet, students answer the questions in order to master and identify the steps of the scientific method for each problem. There are various types of puzzles to be solved also.

Students study the prevention of the four major types of food poisoning. They write a letter of advice to an imaginary friend who has had food poisoning seven times within the last year.

Students research various types of fresh water wetlands and identify the common animal and plant life in these different ecosystems. They further analyze the need to protect these wetlands and explore their varied uses.

Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

Students investigate protozoa. In this protozoa lesson, students identify and classify different types of protozoa using different ecological samples and protozoa charts.
