Sea and Ice Salinity
Learners conduct an experiment. In this salinity lesson, students learn about sea ice, why it is important and how changing amounts can affect the sea. Learners conduct an experiment to find out the effects of salinity on the...
Curated OER
Phytoplankton and Ocean Color
Fifth graders identify function of phytoplankton in the biospere by conducting experiments and simulations and reading for information. They detect the presence of phytoplankton in bodies of water by examining ocean in satellite images...
Curated OER
Crazy Chemistry Lesson Plan
Students study water molecules, cohesion and surface tension. For this molecule cohesion lesson students create chemical reactions that cause a balloon to inflate and another one that results in soap suds.
Curated OER
Chemistry Is a Gas
Students investigate the gas laws and how they apply to changes in gases. In this gas laws lesson plan, students use Boyle's Law and Charles' law to show the relationships between pressure and volume and volume and temperature of gases.
Curated OER
Climate And the Greenhouse Effect
Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...
Curated OER
Drought
Students gain knowledge about the impact of drought in agriculture. They investigate soil types, water flow, and various erosion conditions which occur during a drought and see how farming practices changed after the 1930's.
Curated OER
Weathering Rocks
Fourth graders investigate what natural events cause rocks to break apart and differentiate between erosion and weathering. They conduct an experiment with plaster of paris to observe why some rocks are hard and others break, and...
Curated OER
Weathering
In this weathering worksheet, students investigate the effects of water and acid on limestone. They form a hypothesis for both and experiment to find the results.
Curated OER
Dynamic Wetlands
Students construct and observe a model of two different types of wetlands. In this wetlands lesson, students create a model of a wetland with constant drainage and a wetland that maintains a well-saturated soil. Students observe and...
Curated OER
Combating Corrosion
Study corrosion on bronze statues with a hands-on lesson. As pupils place a penny in water with salt, they observe the changes in the penny throughout a period of a week. They then analyze the pre-conservation and the...
Curated OER
El Nino
Students recognize that El Nino is caused by changes in the atmospheric and ocean content. They conduct a simple experiment, visit websites and create a class poster using individual storyboards.
Curated OER
Diffusion
Young scholars investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in...
Curated OER
Can Cruncher
Students experiment with boiling water and cans to study changes in pressure. For this pressure lesson plan, students use pop cans filled with varying amounts of water heated to boiling. Students drop the cans in cold water and observe...
Curated OER
The Hudson's Ups and Downs
Fifth graders practice interpreting line graphs of the Hudson River water levels to assess the tides and tidal cycles in the estuary. They explore how weather can affect water levels and tides and observe that high tides and low tides...
Curated OER
Acid Rain
Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.
Curated OER
Somethin' Sweet
Students make their own candy. In this science lesson plan, students observe how molecules interact with each other in physical changes and observe how the addition of heat can cause molecules to interact and form new molecules in...
Curated OER
Cake Batter Lava
Students examine how lava flows change the landscape. In this lava lesson students complete a lab activity where they create a lava flow using cake batter.
Curated OER
Air Pressure & Barometers
Fourth graders observe, measure, and record data on the basic elements of weather over a period of time (i.e., precipitation, air temperature, wind speed and direction, and air pressure). Then, they make a barometer and keep record of...
Curated OER
Early Earth History
In this earth history worksheet, students answer 12 questions about geological time, the eras of Earth, the changes taking place in early Earth and the life present during the eras. They also answer 2 questions about the Paleozoic Era.
Curated OER
Create a Cloud in a Bottle
Students look at how clouds form. In this cloud lesson plan, students make a cloud using water, 2 liter bottles and a match. They watch how the pressure and temperature changes the atmosphere in the bottle to create a cloud.
Curated OER
Glaciers and Icebergs
Students conduct an experiment on glacial scraping. In this glacial scraping lesson, students create a small glacier in a plastic cup. Students remove the cup and scrape the glacier across wood and note the markings. Students then make...
Curated OER
Stronger Hurricanes
Students explore hurricanes, the factors that contribute to them, and the role warmer sea surface temperatures may have on them. They perform experiments to observe energy transfer. Students explore the possible causes and effects of...
Curated OER
Coral Bleaching in the Caribbean
Young scholars use authentic satellite data on the NASA website to determine when the sea surface temperature meets the criteria to induce coral bleaching.
Curated OER
Katrina Case Study: Watershed
Students explore the importance of the coastal wetlands. In this environmental lesson, students observe a model of wetland transformation over time. They discuss what changes occur in the wetlands and how hurricanes can affect the...
