Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.

Biologists extract the DNA from a strawberry. After completing the procedure, learners write answers to a few questions on the lab sheet provided. This is ideal lab practice during a DNA unit in your general biology course. 

Young scholars explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed...

Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

In this lab, students explore how organisms are able to survive the extreme environmental conditions found in the Polar regions. Students observe and draw active living rotifers and Tardigrades, design and perform experiments to collect...

Students become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

Ninth graders conduct an experiment to determine how melting sea ice affect sea level. In this earth science lesson, 9th graders explain the environmental consequences of rising sea level. They relate this lesson to global warming.
