High schoolers comprehend how biotechnology can be used to diagnose infectious disease such as protein technologies vs. DNA technologies. They comprehend procedure and uses of PCR, Western Blot, and ELISA as diagnostic tools. Students...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

There are only 10 types of people in the world: those who understand binary and those who don't. The lesson includes four activities in which students learn binary, convert binary to images, understand CCD arrays, and interpret...

Ah, the numerous number of numbers. Individuals research different ways of encoding numbers. After conducting their initial research, they find classmates who have researched a different article and the pair share information. The...

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

It's important to make sure houses can withstand winds. A hands-on activity has learners create a structure out of household materials. They use a fan to simulate hurricane-force winds to see if their structures can withstand the...

It is colorless and scentless, but it makes a large impact on the environment. Learners explore carbon dioxide emissions and what they mean for the environment using an interactive graph. They review changes over time and how they impact...

Here is a good lesson for kindergartners that combines technology, literature, and art. In it, learners take a close look at some famous farm animals. They make the sounds that each animals makes, they use the internet to find pictures...

Learners explore the concept of how brakes can stop or slow mechanical motion. They examine the operation of a bicycle brake and use low cost materials to devise a simple braking system. Finally, they work as a team to suggest...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

This organic chemistry lab activity is appropriate for teaching polymerization, percent yield, melting point, or the types and uses of polymer materials. Chemistry pupils imagine that they are working for a company to develop a special...

Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Middle schoolers observe slides of cork cells and discuss the use of microscopes. They view a power point presentation on "Looking Inside Cells" and take notes aligned with the PPT presentation. They collaborate with a partner to create...

The story of one bird provides valuable insight into general animal behaviors and interactions. Young researchers investigate the peregrine falcon using a web search. They analyze the behaviors of the raptor including its migration...

Students are introduced to using Access and research animals on the Internet. They fill in collected information about animals on an animals access table. They also use queries to classify animals according to their characteristics.

Young scholars investigate the properties of magnets. In this physics lesson, students view a Powerpoint presentation on magnets and list facts about magnets they learned. Young scholars use magnets in the classroom to identify what...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Get your head in the clouds before teaching cloud types to your mini-meteorologists. The lesson opens with a beautiful PowerPoint presentation of clouds portrayed in different artists' paintings. After viewing artistic renditions,...

A beautiful tapestry map of North America is examined by geology masters. The map incorporates the topography and geology of different regions. You can purchase printed copies or a large poster of the map, or if you have a computer lab...
