Students discover that proteins that are the product of DNA translation are different for different species. They determine that by analyzing their mass and charge they can differentiate between two different species. They use some of...

General chemistry classes practice spectroscopy. They grasp the relationships between wavelength, absorbance, and solution concentration. Additionally, they gain valuable practice using laboratory equipment such as burets and pipettes....

Teacher's notes, a materials list, detailed procedure, tips, and extension ideas are all included to make teaching this lesson on photovoltaic cells a sunny spot in your day! After some brief background reading, physical science...

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Here are the instructions for leading your advanced chemists though the process of measuring the nonvolatile components in a sample of paint. No student handout is provided, so you may want to create one based on the procedure explained....

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...

Learners demonstrate use of an Emission tube power supply, a diffraction grating, and a scientific calculator to determine the different wavelengths of light.

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

Students compare their performance of a series of tasks using their thumb and fingers to their performance of the same tasks without the use of their thumb. They discuss the role of fine and gross motor skills and speculate on the role...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...

Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...

Learners practice safety in and out of the science laboratory. In this science lesson plan, students consider a list of safety precautions and guidelines as they apply to the science laboratory and associate the correct laboratory safety...

Young scholars determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Young scholars determine the heat required to melt one mole of ice using hot...
