How do magnetic fields differ? Allow scholars to see the difference between 2-D and 3-D magnetic fields. They construct models of both and observe how they are similar and different. It is the fifth installment of an 18-part unit.

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

There are some amazing ways species evolve to survive. From large ears to sneezing salt, learners read about these interesting adaptations in an interactive lesson. Great to supplement an in-class lesson, it also works well as a remote...

Students demonstrate the steps of evaporation, cloud formation, and precipitation within the water cycle. They make and demonstrate how to use a hygrometer to record daily humidity and describe how rain, snow, and sleet form.

Students observe the sky and weather to gather data. They conduct experiments to answer questions about the sky and weather phenomena. They measure, analyze and present data. They create sky windows by gluing sky colored paint chips...

Young scholars compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in...

Construct a maze in your classroom and have a blindfolded scientist act as a space rover, maneuvering unfamiliar terrain while another scientist plays commander. Classmates record the number of occurrences of the commander having to...

Students create models of the three major types of volcanoes and determine how a volcano's shape is related to the type of material erupted. They then observe a demonstration that simulates the nature of two volcanic materials: lava and...

Students discover how worms contribute to the balance of the environment. In this composting lesson, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.

Students identify the properties of a magnet. In this physics activity, students explore the strength of the magnet by testing out how a magnet reacts to various materials. The various objects the students test include paper clips,...

Yum! Using graham crackers, dried fruit sheets, and frosting, tectonics technicians demonstrate the different types of plate boundaries. If you want to encourage youngsters with an activity that is both educational and edible, then this...

Seven problems regarding gravitational pull are presented in this physics drill. Pupils solve for displacement, time, speed, and acceleration. Critical thinking and problem solving skills are both required to complete the assignment. 

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Lead your class on a journey to the planet Jupiter and provide them with fun facts in the process. Learners explore radio waves emitted by Jupiter to further understand how this data helps our daily lives. They conclude by discussing...

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized lesson...

Learners investigate the interdependence of agriculture and the environment. They research areas of interdependence and provide examples of situations where farmers are practicing conservation in the local area. Their findings are...

Students study thermal energy and energy transfer to sea ice processes. In this energy transfer instructional activity, students make their own ice cream and discuss energy transfer and thermal energy. Students view a radiation overhead...
