Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

Do your high school scientists know the four methods scientists use to communicate information? A simple experiment discovering the relationship between gas pressure and volume allows pupils to practice all four. After completing the...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

Time to put the knowledge to the test! Young scholars take what they know about the periodic table and build their own from scratch. Using clues from 26 different elements, they place elements in a blank periodic table. The clues include...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

Anyone that lives around snow knows that adding salts to water increases its melting point. Are there solutes that affect the boiling point as well? A scientific experiment has learners add different solutes to water and then...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

No vacuum cleaner? No problem, just build your own. Scholars apply knowledge of currents to build a model of either a vacuum clear, a hair dryer, or a toy car. While the class completes the activity, instructors consider gender...

Get the class up and going with a instructional activity that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

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...

Fixin' to add a great resource to your plans? Scholars perform an experiment to investigate nitrogen-fixing bacteria from plant roots. Along the way, they learn about the concepts of symbiosis and mutualism.

Now you have a new excuse not to do your homework. A long-term experiment has learners explore cellulose-digesting enzymes. They simulate how paper breaks down in a compost bin. There's no need to blame your dog for eating your homework...

Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

You'll never forget the importance of toilet paper and hand washing ever again. Scholars perform an experiment to model the transfer of microbes in the bathroom. They perform three trials to test the transmission of yeast using their...

Enzymes: not just for breaking chemicals apart. Young biologists perform an experiment on potatoes. They first remove starch from potato extract. They then add the resulting liquid to samples of glucose-1-phosphate, glucose, maltose, and...

Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based instructional activity. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

Test your pupils' understanding of the scale from macro to atomic. While displaying images of different materials, learners identify what they would need to make that material visible. Their choices range from the human eye to an...
