Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

Young scientists investigate the elements found in our solar system and then construct a model of a comet. They apply their new knowledge to the formation of the solar system. 

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

Here is a well-designed science lesson that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own eating and drinking...

Who knew that a possible answer to Earth's energy resource problems was lurking deep beneath the ocean's surface? Part four of a six-part series introduces Earth Science pupils to methane hydrate, a waste product of methanogens. After...

When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

Introduce organic chemistry through an analysis of flavor. A three-part unit begins with an overview of the components of flavor. Next, scholars prepare esters through esterification. Finally, they examine how all senses have an impact...

Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Unravel the DNA molecule in just over a minute! Future geneticists listen and watch a video exploring DNA's structure, function, and the interaction of the genes and proteins that decode and interpret the complex molecule. Scholars...

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or...

Step right up! An engaging research-centered lesson, the third in a series of six, has young archaeologists study the amazing animals of the Cambrian explosion. Working in groups, they profile a breathtaking and odd creature and learn...

Want to hear a joke about sodium? Na. Young scientists test various materials to identify if they include protein, starch, and glucose by using the Biuret test, iodine starch test, and Benedict's test respectively. After practicing with...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the instructional activity and a...

Ever wonder how they solve those mysterious murders in TV crime dramas? The second of four units in a Biotechnology series introduces scholars to the many methods of DNA analysis. Pupils create and run their own gel electrophoresis...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Do you want to learn about how you learn? Help pupils become the best learners they can be by teaching them how their brain works. The resources available include videos about brain structure and a study guide full of activities that...

Climate change affects even the largest and intimidating of landforms—even Mount Everest! A resource helps teach learners the connection between global climate change and its effects on Earth. Activities include videos, class discussion,...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...
