Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

This is a must-have resource with everything you'll need for studying food safety with your pupils. From handwashing scorecards and cleaning kitchen surfaces to navigating the world of microbes and food-borne illnesses,...

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Oh nuts! Do macadamias or almonds produce more thermal energy? Energy enthusiasts find out with this experiment. The objective is to demonstrate to your class how the chemical energy contained in foods can be converted into useable...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Why was the North Atlantic Treaty Organization (NATO) formed, and what is its mission? Learners discuss NATO's participation in various events throughout the Cold War and work in groups to analyze whether those responses were appropriate.

Ever wondered how your brain manages all of the information it receives every second of every day? The sights, the sounds, the smells ... each one filed away for later use or moved to the front of the line so your body can react. Through...

Test the efficiency of your memory! Scholars test each other's memory as they explore factors that affect memory retrieval. Through experimental analysis, they discover there are different types of memory, which has an impact on the...

Investigate experimental design through a hands-on exploration. A creative lesson allows learners to design an experiment to monitor the effects of alcohol on the C. elegans worm. After conducting the experiment, individuals analyze...

What do lab tests reveal about a patient's health? Scholars perform a simulated urinalysis on two different patients by testing color, pH, glucose levels, and protein levels. Then, they compare their findings to what they know passes...

Understanding the life cycle of a mosquito helps us understand how to prevent the spread of diseases they carry. A lab investigation provides learners with the opportunity to track the two-week life cycle of the mosquito. Scholars make...

Slow the spread of disease by slowing disease carriers in their tracks. Learners explore just how they might accomplish this as they experiment with the life cycle of a mosquito under different conditions. Scholars design and conduct...

Observe a flatworm as it regenerates its own head. A laboratory exploration asks learners to cut a planaria worm at different locations and then observe it regenerate. Using data collected during the exploration, they make conclusions...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

Many scientists attempted alchemy for hundreds of years before a full understanding of metals became clear. Scholars take a penny and, through two different chemical reactions, make it appear to turn into silver and later gold. They...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

A hands-on experiment applies chromatography to separate both the colors and components of grape-flavored Kool-Aid. Performing two separate activities, learners first use chromatography to divide the colors. The second activity results...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...
