Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Introduce your classes to a fourth state of matter! Liquid crystals have a colorful sheen that changes based on different physical factors. Learners use this information to create a liquid crystal thermometer where the color of the...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.

How quickly does a plant transpire? Learners explore this question through measuring water uptake with a potometer. They time the movement of a bubble a set distance to understand the motion and rate of speed.

How important is the tip of a new shoot on a growing plant? Individuals learn about the results of experiments on shoot tips and must interpret them. They apply previous learning and connect complex ideas through advanced analysis.

When stressed, do you prefer the fight or flight response? Scholars observe, measure, and identify the body's response to stress using a well-researched methodology. They learn about the autonomic nervous system, hormones, and more.

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

How do scientists prove tiny living things respire? Young scientists build a respirometer and measure respiration rates in living creatures. By comparing the measurements of both plants and animals, they understand the similarities.

Can your class help the people of Nepal? Scholars take an in-depth look into the social injustices and struggling economy of a country in turmoil during a multi-day role-playing exercise. After reviewing information on the problems...

How do you solve a conflict that's been around for so many years? Scholars discover the viewpoints of stakeholders in the Israeli-Palestinian conflict during an emotionally charged simulation. A facilitator moderates discussions between...

War-torn Palmyra needs your help! Young negotiators play the part of citizens of opposing countries through an eye-opening simulation. The fictional countries of Siwa and Nizwa stand at the brink of war, and your class' job is to create...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

They say elephants never forget—and your class won't forget an insightful modeling activity either! Junior zoologists take part in a mock elephant census using the sample count and total count methods. The included materials provide...

How did the Ebola virus first infect humans? Young virologists examine genetic sequences from the 2014 Sierra Leone outbreak to find similarities during a riveting activity. Following similar methods used by MIT and Harvard, partners...

Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...

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.

All oxidation-reduction reactions can be reduced to a gain or loss of electrons. A two-part virtual lab first has users perform an experiment to order four metals from strongest to weakest reducing agent. It then requires aspiring...

You'll need to concentrate on the concentration lab to get it done. Given a virtual beaker with a silver chloride solution of unknown concentration, scholars find the silver ion concentration in the solution. Of course, they must show...

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...

Combine automotive science with chemistry! Young scholars investigate an alternative to the traditional engine coolant. They mix the chemicals virtually and collect data to determine the specific heat capacity. 

It's gettin' hot in here! An investigative activity has learners measure the heat of reaction in a virtual setting. After exploring the reaction, they attempt to create a solution at an exact temperature.
