Third graders relate that the quality of their drinking water is subject to the condition of the environment and water found in streams and creeks in their community. They track the travel of a wad of paper from a student's desk to a...

Young scholars continue their examination of the water cycle. In groups, they present their findings to the class after researching a specific topic related to the water cycle. They spend the rest of the lessons asking questions and...

Explore the sun's ability to distill contaminated water with this simple set of classroom experiments. After filling two glass bowls, one with muddy water and the other with salt water, they are covered with plastic wrap and placed...

Earth science explorers design an experiment to demonstrate that the albedo of a surface affects its temperature. They test to find out if moisture on the surface affects temperature. They discover whether or not concrete or asphalt heat...

Students participate in an experiment about evaporation. In this water cycle lesson, students use water, thermometers, and measuring tools to make a puddle and measure the size four times throughout the day. Students discuss their data...

Greenhouse gases affect marine wildlife in life-threatening ways. Through experimentation, your classes explore the acidification of water from the main greenhouse gas carbon dioxide. As they introduce carbon dioxide to water, a pH...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Students use the scientific method to test an idea regarding the structures of a plant as it supports the biological evidence for life. For this growing roots lesson, students use organizing sheets to record their findings. Students...

Learn the science behind ocean acidification and its effects on ocean wildlife. Young scientists conduct a laboratory investigation that monitors the acidity level of water. While burning a candle, learners capture the carbon dioxide in...

Students explore water in depth through discussion, research, and experiment. Students apply map skills to locating particular regions of the world as they relate to water. Students predict water quality based on information researched...

Students view a teacher demonstration that prompts them to solve a problem using the scientific method. In this scientific method lesson, students guess which cup has water and are presented with a conundrum when the water does not...

Students complete a series of activities in which they study atoms, molecules, and the presence of atmosphere. They study the water cycle and the Greenhouse Effect by investigating and completing handouts.

Students explain how uneven heating of Earth affects wind and water currents. They describe the limits on current technology in predicting weather and how the Water Cycle is related to local weather.

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

High schoolers are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use...

Young scholars investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water...

Learners experiment with air saturation. In this earth science lesson, students first complete an activity which teaches humidity. Then they use the scientific method to create their own experiments to test how long it takes a...

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...

Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.

Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

Sixth graders use the scientific method to test variables of evaporation. In this evaporation lesson plan, 6th graders test a wet handprint on a paper towel and relate this experiment to weather conditions.

Students explore the ecosystem by conducting a ziploc bag experiment. In this recycling lesson, students identify decomposer organisms in our environment and how they speed up the recycling process. Students utilize a ziploc plastic bag,...
