Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

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...

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

From windows that tint themselves to OLED technology, electrochromic polymers are redefining our ideas about conducting materials! Introduce your chemistry class to the emerging trend with an exciting lab activity. Budding materials...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

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 lab activity does not have to be done with AP environmental scientists. It can also be done with middle to high school earth scientists. The procedures aren't complex. Learners determine the density of dry and wet sand in order to...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Make sure to read through the activity procedures thoroughly before teaching this lesson plan because the materials list is incomplete. Also, the mentioned worksheets and booklet are not available. However, there is no need to discard...

Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates,...

In this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...

In this chemistry lab, students determine whether or not their saliva is acidic, basic, or neutral. After completing their test, they answer 6 analysis questions.

How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...

Mini mycologists plan an experiment to determine what affects the growth of mold on gelatin. A list of available materials is provided, but the procedure needs to be designed by the lab group. A data table is also provided in...

Here is a handy handout to give any science class as a guide to writing lab reports. It is a blank outline that you can have aspiring scientists fill out when they experiment, or imitate as they record their experiments in a lab journal....

Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...
