The Day the Mesozoic Died
While this is not the traditional, step-by-step lesson plan, it is chock-full of material that you can easily incorporate into your earth history unit. Its main purpose is to serve as a guide to using a three-part film, The Day the...
Curated OER
Hovercraft
Students assess human impact on water quality. They determine how the force of friction retards motion. Pupils describe and measure quantities that characterize moving objects and their interactions within a system: Time, Distance,...
Curated OER
Graphing Toad/ Frog Respiration
Learners measure respiratory rates on live toads, and the effect water temperature has on their findings. In this scientific method lesson plan, students record their findings and present them in a graph, comparing the results.
Curated OER
Proteomics
Students analyze data taken from proteomic experiments. In this biology lesson, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.
Curated OER
THE CHERNOBYL DISASTER
Students explore how a nuclear accident can affect biological systems. They examine the case of the Chernobyl nuclear meltdown in 1986.
Curated OER
Plant Transpiration
Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Urban Ecosystems 5: In Defense Of Cities
Middle schoolers explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth...

Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Investigating the Effect of Concentration of Blackcurrant Squash on Osmosis in Chipped Potatoes
Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...
Curated OER
Understanding Kidney Disease
Students experiment to determine information about kidney function. In this kidney function activity, students use the scientific method to experiment with eggs, water, salt, sugar, and vegetable oil to simulate kidney function. They...

The Effects of Photosynthesis on Plant Growth
Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...
Curated OER
Osmosis and Diffusion: Egg Lab
Students examine why diffusion and osmosis happen in an egg cell. For this diffusion lesson students demonstrate a semi permeable membrane.

Serc: Investigating Osmosis Using Water and Gummy Bears
In this biology classroom lab, students investigate the affect of soaking a Gummy Bear in water. They collect measurements of height, width, and mass before and after the soaking of the candy overnight. Students calculate % change for...
