Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...

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...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Here is a fantastic experiment-based lesson plan on water conservation, waste, and filtration. The lesson plan is well-developed and provides background information, discussion leads, and six scripted lab activities anyone can do. The...

Electromagnetic radiation behaves like both a wave and a particle. Help classes explore this concept through a lab investigation. Young scientists create optical interference patterns on a glass slide using a carbon layer. They analyze...

Beginning biologists prepare a sugar solution for yeast cells to live in, and divide it into two different jars. Samples from each jar are viewed with a microscope, and then one jar is placed in a warm environment and the other a cold...

Students explore the DNA of strawberries. In this science lesson, students extract the DNA of strawberries. Students complete a lab report.

Learners explore the importance of sun safety in relationship to skin cancer prevention. They test the effectiveness of various sunscreens and administer and analyze a simple survey to their peers. In addition, they implement a public...

High schoolers develop an ability to distinguish between simple error, misconduct and fraud. Students are lead to consider a widening circle of the consequences of misconduct and fraud. They expand their knowledge on the...

Middle schoolers investigate seed germination. In this lesson on scientific prediction, students conduct a scientific experiment using oat seeds.

Students determine the identity of the three classes of levers while explaining how each works. They wait a video clip that shows uses for different types of levers and work as a class to write a KWL chart. Finally, they make a model fo...

Students investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions created...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

Young scholars examine how to conduct simple investigations and use simple equipment to gather data.  In this magnet lesson students decide what types of objects are attracted to magnets. 

Fifth graders investigate buoyancy by conducting a science experiment.  In this water properties lesson, 5th graders predict which of their different paper boat designs will float for the longest period.  Students conduct the...

Young scientists discuss the results of carelessness during experimentation and the temptation to misrepresent findings. These activities are intended to develop the ability to identify scientific error, misconduct, and fraud. Use this...

Young scholars investigate why a balloon flies in one direction as air escapes in the opposite direction, which helps them understand the nature of rockets and fireworks. Individually and in teams, students conduct research to create a...

Students explore electricity by conducting a series of experiments. In this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.

High schoolers investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students...

Young scholars investigate conservation laws using a potato launcher. In this physics instructional activity, students measure angles, time and distance of the potato. They discuss applications of experiments like this.

Eleventh graders test the pH and alkalinity of Pago River. In this ecology lesson, 11th graders collect data and use spreadsheet to graph results. They analyze and share their findings with the class.

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Students research African-American mathematicians.  In this middle school mathematics lesson, students celebrate Black History by conducting Internet research on an African-American, mathematicians or scientist.  Students...

Eighth graders investigate different gas behaviors. In this chemistry lesson, 8th graders describe how changing volume and temperature affect gas particles motion. They collect data and make a generalization about these variables'...
