Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Explore genetically modified foods through various experiments. In this biology lesson, high schoolers discuss the safety issues related to GMF's. They conduct a PCR analysis to identify the presence of genetic modification.

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Middle schoolers participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Emerging electricians build a simple ammeter for making measurements on an electric current. They test the placement of solar cells in both series and parallel circuits and examine the magnetic field produced by the movement of electrons...

Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Students identify the characteristics of minerals. They complete proper identification tests and record the data in an organized fashion. They list important uses for minerals as well.

This lesson is preparation-intensive, but well worth the investment. You will construct five or six portable testing stations with which lab groups will gather data on the best position for collecting sunlight with a solar panel. This is...

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Students perform a redox titration of iron. In this iron titration lesson plan, students use potassium permanganate to oxidize iron so they can determine the percentage of iron in a sample of fertilizer.

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

In a previous lesson, learners build an ammeter. That ammeter, or a pre-made one, is required in order to carry out this lesson. The objective is for lab groups to design a way to connect solar cells that can recharge a battery. Basic...

Students determine the solubility product constant and the concentration of a hydroxide. For this solubility product lesson plan, students use a solution of calcium hydroxide to neutralize a known concentration of hydrochloric acid. They...

Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.

Seventh graders complete a challenge to create a catapult that projects a marble or other projectile at least one meter. While experimenting they apply the Four Question Strategy to answer the question, " How can I make one modification...

Students make polymers in the lab. In this polymers lesson plan, students make a nylon fiber polymer chain. They define monomers, polymers, addition polymerization, condensation polymerization, crosslinking and cyrstallinity.

Students identify safe practices that must be followed to assure the food chain from the farm or ranch to dinner table is providing safe and quality food for the consumer. Students visit websites to examine numbers of food borne...

Young scholars 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...

In this hazard symbols worksheet, learners are given six symbols commonly used in the lab to indicate hazardous materials, agents, and situations. Students look for each symbol around the classroom, on worksheets, and in textbooks.

Young scholars create a bird feeder to form their technological skills and create a better bond with nature. For this nature lesson plan, students use websites, technology, brainstorm ideas, and build models.

You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...

Learners conduct Internet research on the different parts of the skeletal system. Then they create a model arm that demonstrates how muscle and bone work together to create movement.
