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...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

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. 

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 instructional activity introduces the concept of restriction analysis,...

Learners study about electrochemistry by increasing their understanding of electron transfer and its role in chemical changes. They explain that energy appears in different forms. Heat energy is in the disorderly motion of molecules.

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The lesson plan is simplistic, but the Internet resources...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

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...

An online reading and interactive game bring the path of a carbon molecule to life for your earth science explorers! As an assessment, learners can map out or write about their experience in the carbon cycle. Thoroughly written...

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...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Students study the effects of dietary supplements on bodily functions.  In this health activity students calculate their caloric needs and research dietary supplements. 

Students explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

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 plan, 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...

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

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...

Earth science experts learn about the roles of nitrogen by taking a virtual journey through the nitrogen cycle. Completing a passport worksheet along the way, they move from place to place around the classroom by the toss of dice. Each...
