Neurons send electrical signals throughout a body based on chemical communication. Individuals stimulate a neuron to see the effects. They notice the sodium-potassium channels along with ions, concentrations, and a membrane potential...

Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

All chemists know that moles are made of molecules. Individuals see how changes in the amount of solute affect the concentration of the solutions. By manipulating solute amounts (moles), solution volume (liters), and solute types, the...

Seamounts in the Coral and Tasman Seas are home to more than 850 different species. Groups explore hydrothermal vents, researching the organisms found there and their energy source. They also learn about seamounts, exploring their unique...

A tube worm's outer covering is made of chitin, the same material that makes up the shells of lobsters and crabs. Scholars create tube worms and analyze and discuss the longevity of organisms living near cold seeps. They then discuss and...

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

The deepest part of the ocean is the Marianas trench where two tectonic plates meet. Scholars explore plate tectonics and their boundary types by completing hands-on activities throughout the instructional activity. Specific areas, such...

Some fish contain proteins that act like antifreeze in order for them to live in the frigid waters of Antarctica! High schoolers determine how much antifreeze a fish needs to lower its body temp to -2.5 degrees. Teachers act as a...

Landforms in Beacon Valley, Antarctica, where there is no snow, bear a striking resemblance to landforms found on Mars. Scholars identify landforms found in Beacon Valley through analysis of topographic maps in the activity. They then...

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

The Deepwater Horizon oil spill directly impacted an area of the Gulf of Mexico the size of Oklahoma. A marine biology lesson looks at the impact of an oil spill on the deeper parts of the ocean. Scholars download actual data collected...

A cold seep is an area on the ocean floor where hydrocarbons leak from the earth, creating entire unique biomes. Learners explore cold seeps, photosynthesis in the ocean, and its limitations due to loss of sunlight. They further explore...

Sediment samples from the ocean bottoms tell scientists about climate change, pollution, and changes in erosion for the area. Groups of learners focus on sediments and their movement through water. During a hands-on activity, they...

Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

In 1993, five biomedical engineers in Edinburgh, Scotland, created the first functional bionic arm. In the activity, learners explore the world of bioengineering through discussion and hands-on exploration. In groups, participants...

My friend told me how electricity is measured and I was like Watt! In the hands-on activity, learners explore electricity by building circuits, both parallel and series. They also determine how increasing the number of light bulbs and...

Developed for the 100-year anniversary of Marie Curie's Nobel Prize, a book offers lessons and activities to interest scholars in chemistry. It is divided into modules, so you can pick information from each to create your own lesson...

When is the last time pupils did a happy dance in class? Scholars act out photosynthesis and dance excitedly in front of the class. The resource also comes with a worksheet for those waiting or who have already completed the...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...

Looking for a valuable resource on the spread of infectious diseases? Here is a lesson in which pupils simulate the spread of diseases and learn about how to prevent them from spreading. Class members read case studies about diseases,...

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...
