Curated OER
Plotting the Ocean Floor
Fourth graders plot points on a graph, connect the dots to make the ocean floor profile and label the topographical features. They utilize a worksheet and a website imbedded in this plan to plot the ocean floor.
Curated OER
Wave Math
Students identify the different factors affecting the size and shape of ocean waves. In this math lesson, students calculate wave speed and wavelength given a mathematical formula.
Curated OER
Sonar Mapping
Students use a shoe box to create a seafloor model and use cardboard for layering inside of the shoe box to simulate the ocean floor. They probe the ocean floor to simulate sonar echoes. Finally, students graph their data to get a...

Water Density Boundaries
Learners create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Cooking with the Sun!
Learners access prior knowledge of solar energy and understand that solar energy produces heat. In this solar cooker activity, students complete grade appropriate experiments using the heat of the sun. Learners complete a worksheet on...
