Students 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.

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

Some fish contain proteins that act like antifreeze in order for them to live in the frigid waters of Antarctica! High schoolers determine how much antifreeze a fish needs to lower its body temp to -2.5 degrees. Teachers act as a...

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. 

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

Learners 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 of by...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Go on a traveling adventure throughout Australia, Oceana, and Antarctica! This textbook excerpt offers a full unit of study that can easily be supplemented by extra projects or research materials. Learners study maps, read about...

For this solvents pre-lab worksheet, students describe the difference between a polar and non-polar solvent and also the dangers associated with hexanes and iodine. This worksheet has 12 short answer questions.

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.  For 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...

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second instructional activity of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils...

In this vocabulary learning exercise, students decipher which word would complete the sentence best. All words begin with the letter "G."

Young scholars 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.

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

Mix polar and nonpolar molecules together and observe changes in potential energy.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Students will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...
