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...

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,...

Students measure respiratory rates on live toads, and the effect water temperature has on their findings.  In this scientific method lesson, students record their findings and present them in a graph, comparing the results.

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Learners explore how a nuclear accident can affect biological systems. They examine the case of the Chernobyl nuclear meltdown in 1986.

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.

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...

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...

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...

Using a table, students solve 12 word problems about the weights of various foods at the grocery store. The solve addition and subtraction problems as well as convert kilograms to grams.

Students experiment to determine information about kidney function. In this kidney function lesson, students use the scientific method to experiment with eggs, water, salt, sugar, and vegetable oil to simulate kidney function. They...

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...

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic...

For 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...
