Students run clockwise around a track in the gym, pretending they are the blood that carries oxygen through the body. They go to the "mouth" station where they take three breaths and pick up an object that represents oxygen. Students...

Breaking up is hard, especially with a third part involved! Watch as molecules of hydrogen, oxygen, and nitrogen try to keep it together as a neutral third atom bombards them. Users control the reactive molecules and the velocity of the...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

So how does the carbon cycle work? Kids participate in a hands-on activity that allows them to understand the chemistry behind climate change and global warming. They act out the process of photosynthesis by labeling themselves as...

Oxygen and carbon dioxide freely cross cell membranes. The simulation demonstrates the diffusion of these across a permeable membrane. To create a great visual for users, it graphs the balance of molecules as it changes throughout the...

Students explore the parts of the heart and how blood travels throughout the body. They conduct a simple simulation to demonstrate the path that blood takes through the body and the functions it performs.

Students participate in a role-play activity to lean about red and white blood cells, veins, capillaries and arteries. They also see how blood passes through the heart, lungs and out of the body, carrying oxygen and nutrients.

When you get to the heart of the matter, you learn a lot about an organism by studying its circulatory system! A perfect resource for a zoology or anatomy class, the simulation gives users a peek inside a variety of vertebrates to...

Take it all the way back! Young scientists discover the changes that took place from the time Earth became solid to present day through an interesting interactive. The resource guides users through key events that have shaped our world...

How many different molecules can you build? In a simulation, learners make molecules from given atoms. There are numerous collections from which to build three to five molecules from given kits of atoms. Scholars can also view their...

Fourth graders discuss and identify the components of photosynthesis and the products of this process. They participate in a class discussion about the importance of oxygen, and in small groups act out the process of photosynthesis. ...

Young scholars mode the transport of blood through the circulatory system with a water relay. In this circulation lesson, students measure amounts of water and transfer them from one container to another. They use this activity to model...

Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.

Students examine the importance of submerged aquatic vegetation in the St. Mary River ecosystem. They identify different characteristics of common eelgrass and discuss water quality, photosynthesis, habitat, oxygen production.

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

Are you a koalafied biologist? The instructional activity begins with research about human survival and our ecosystem. Then, an online training module simulates the effects of changes to the plants and animals in an ecosystem. Finally,...

Pupils make observations while eating food. They act out the process of food breaking down in the body and the roles of various chemical components, such as sugar and protein. It concludes with an activity illustrating the process and a...

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...

Students gain understanding of several of the biogeochemical processes in microbial mats. They acquire knowledge of the different roles of organisms in a microbial mat ecosystem. They understand how microbial mat ecosystems contributed...

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

Students develop an understanding of our planet as a system by designing a very-long-duration space mission in which the life-support system is patterned after that of earth.

Middle schoolers examine the world of the Arkansas alligator and topics that are related to wetland environments. They pay attention to the relationship between geography, climate, environment, and the animals who live there. A role-play...

Hosting a Healthy Field Day will take a lot of planning and organization, but with a lot of parent participation it can come together very well. The resource describes seven stations of the ten that were presented. Each of these has a...

The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...
