New ReviewHave you ever seen an egg bounce? Three interesting and simple hands-on experiments with eggs teach basic concepts about chemical reactions. First, participants cook an egg in alcohol to learn about denaturing proteins. Then, they watch...

New ReviewHave you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

New ReviewGive pupils one of those light bulb moments! A hands-on lesson asks scholars to create and build three different circuits to light a light bulb. They then compare results to determine the best approach to light a set of holiday lights.

New ReviewHelp classes unleash the power of money. Using knowledge of current and circuits, young scholars create their own batteries using coins. They measure the voltage of their homemade batteries and compare them to the traditional double and...

New ReviewThe lower the better! Young scholars experiment with salt and water to determine how the combination affects temperature. By applying concepts of thermodynamics, they create their own modifications to attempt to achieve even lower...

More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

Scholars learn the stories of the universe with a unit study on the cosmos. They model the universe, learn about the relationship with the electromagnetic spectrum, understand the big bang theory, and debate the existence of life on...

Astronomers only observe four percent of the universe as the rest hides in darkness. The size, shape, and movement of the universe are the focus for an long-term high school unit. Its 43 lessons include hands-on experiments, direct...

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...

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

Humans eat around 93,205 miles of DNA in an average meal. Scholars learn how to extract DNA from a strawberry using a presentation. It walks through each step and explains why the process works. Comprehension questions encourage...

Francis Raoult discovered the change in boiling points of solutions varies by the number of particles in the solution. Scholars apply the concept to determine the molality of a solution based on the change in boiling point. They use an...

How effective are cells at repairing UV damage? An inquiry-based lesson has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

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 document...

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...

What do budding scientists know about moles and reactions? Using an attention-grabbing lab experiment, young scholars collect data to apply the law of conservation of mass to predict the mass of gaseous products. They examine several...

Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

The more you know, the better your predictions! Using a hands-on lab experiment, collaborative groups collect information about ionic interactions. They record data describing the precipitate of reactions and use their information to...
