How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...

Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.

Class members have an opportunity to consider issues faced by refugees and Internally Displaced Persons (IDPs) by participating in a series of activities that illustrate some of the challenges refugees experience. 

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Henri-Louis Le Chatelier wrote many papers throughout his 85-year life, but he is remembered for one of his earliest discoveries, now known as Le Chatelier's Principle. The final activity in an 11-part series encourages young chemists to...

Motivate young citizens to make a positive difference through volunteering. Scholars examine the local and school community to discover ways the class, as a whole, can volunteer their time to help one or the other, then reflect on their...

Never let them see you sweat ... unless you can't help it! Scholars design an experiment to determine the effects of stress on the body. They monitor sweat production under different conditions and relate the response to the function of...

Test the levels of vitamin C in different juices. After a lesson on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the titration to study the...

Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.

Here's a lab that may make you rethink that morning cup of coffee. Biology scholars test the effects of caffeine, alcohol, and nicotine on the behavior of zebrafish through an intriguing experiment. Learners observe fish...

Can your young chemists identify the most commonly used chemicals in the lab? Introduce the class to the go-to substances in most middle and high school chemistry experiments with an interactive. The resource offers timely feedback as...

Instill the concept of adaptation with the help of Blubber Gloves—ziplock bags, shortening, and duct tape. Scholars discuss how animals and plants keep warm in polar regions, record their predictions, and try on their Blubber Gloves to...

You'll feel strongly about this weak acid and base virtual lab! Scholars experiment with the wonders of dissociation constants in a simulated lab environment. The accompanying written work includes buffer preparation, titration curves,...

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Let's hope that your soap is doing what it's supposed to! The second of six installments in the Cells unit has scholars perform an experiment cultivating bacteria in Petri dishes. They test soaps and detergents to see which is most...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

Why do psychologists conduct experiments in controlled laboratory settings? High schoolers gain an understanding of the importance of controls with an activity that involves naturalistic observations with no imposed controls.

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.

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Learn about the study of medications, including those found in nature and those made synthetically. The first of four lessons in a series on pharmacology includes lectures, hands-on experiments, research, and more.

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

Some say there is no place like home. Jane, a character in Jane Eyre, is thankful no other place is like the terrible home of her aunt. Jane is thankful that her mean aunt is convinced to send Jane off to school. Readers learn of the ups...
