Here's a solid resource for solubility. Given the solubility of copper chloride at two different temperatures, young chemists need to determine the solubility at a third given temperature. Using a virtual lab, they design and conduct an...

Blast off! How do satellites, space shuttles, and space stations escape Earth's gravity and achieve orbit? Young astronauts study rocket science (literally) with an interactive lesson. They discover the four main uses for satellites, how...

This is not your standard standardization lab! Take titration into the high-tech age with a simulated workbench. Learners perform titrations to standardize a sodium hydroxide solution using a KHP solution of unknown concentration....

Take your class up, up, and away with an engaging weather balloon simulation! Individuals get hands-on experience in creating and launching their own airborne labs to study how temperature and pressure affect substances at 100,000...

No chemistry lab? No problem! Scholars use a virtual lab to determine the solubility product of four different chemicals. They then use the results of their experiments to see if higher solubility product values equal greater solubility.

Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results....

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

Food storage matters! Scholars learn how the amount of water in corn can affect its rate of spoilage. They create a control group, then test three corn samples stored in three different locations for water activity. As a result of the...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

How does water activity play a role in food spoilage? First, the learners think about which types of foods would be best to take on a backpacking trip based on the water activity of different foods. It then walks through why water...

What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Ready to heat things up in the lab, but your class doesn't know its way around a Bunsen burner? Scholars get familiar with heating apparatuses through a series of puzzles designed to promote vocabulary and reasoning skills. The...

Play a little game of concentration! A virtual lab investigation allows learners to predict the products and reactants of a DNA reaction. They make their calculations and then test their predictions in the lab workbench.

Talk about a cool tool! Convert between units with the click of a mouse using a handy online resource. Enter the starting measurement and units for quantities such as torque, speed, and inertia, then sit back and relax while the computer...

Create a small but useful little program that allows you move a dot with your mouse and see the coordinates change as the mouse moves.  Starting with a dot that moves with the mouse, add to this program the text of the points...

In this magnetism learning exercise, students answer ten questions about magnets, their magnetic poles, the magnetic lines of flux and how magnets work.

In this electromagnetism and electromagnetic induction learning exercise, students answer 12 questions about electricity, about the magnetic fields in given diagrams, about the right-hand rule and about electric current and voltage in...

In this online interactive history worksheet, students respond to 10 short answer and essay questions about Francis Bacon's The New Organon. Students may check some of their answers on the interactive worksheet. 

Design an experiment to order Cu, Mg, Zn and Pb from strongest to weakest reducing agent.

In this lab, students perform a virtual ELISA (enzyme-linked immunosorbent assay)to test whether a particular antibody is present in a blood sample. Students engage in key science practices, including experimental design and data...

Review your understanding of the scientific method as you play this underwater game. Collect clues in bottles, pearls, and answer questions. There are three levels of difficulty to choose from.
