Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

Test the levels of vitamin C in different juices. After a lesson on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the titration to study the...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

Young scholars observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Upcoming marine biologists consider a list of organisms residing near the Lost City hydrothermal vents and construct a food web. They compare the food web to that of a cold seep community, of which they should have previous knowledge....

Here is an interesting science lesson. Pupils discover that carbon, just like water, is absolutely necessary for all living things to survive. They study how it cycles through nature, become familiar with the periodic table, and look at...

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...

Observe onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. High schoolers draw a sketch of the mitotic cells, explore why cells undergo mitosis and learn how...

Students, working in small groups construct scale models of the planets and solar system. They examine images of Mars and discuss what might have caused the features. They record facts about their planetary research in their journals and...

Students study sea surface height and temperature and other characteristics of an El Nino.  In this ocean impacts lesson students examine the factors that influence an El Nino or La Nina. 

Another A+ lesson plan on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab...

Pupils pose their hypothesis, they ready their instruments, then record their observations. This is the science of sound activity. They move through 5 stations, each focused on a different element of aspect of sound. Check this activity...

Take the old baking soda and vinegar volcano to the next level by using it to study repeated lava flows over time, examine geologic features on Earth and Mars, and speculate about some of the formations on Mars. 

Learners study how changes in the environment can drastically affect the survival of an animal. After a class discussion, pupils are divided up into groups and are given the task of coming up with the best environment to allow brine...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Have individuals wash their hands with soap and water, give one of them a yeast-covered piece of candy, and then have him shake hands with the person next to him. Handshakes continue down the line until everyone in the class has had...

Five individuals in the class are "infected" with cholera! The rest of the class serves as investigators to discover the source of the outbreak. They test drinking fountains around campus for contamination. You, of course, will secretly...

Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Juvenile geologists drill clear plastic straws down into a playdough sedimentary rock model, pulling out sample rock cores. As they analyze their cores, they apply the law of superposition and discover that originally horizontal layers...

A set of PowerPoint slides supports a lecture or class review of weathering and erosion. Viewers learn the definition of each and examine various photos for evidence. Erosion is further depicted as caused by wind, water, and ice....

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...
