Fourth graders work together to collect air samples for testing. They determine the amount of pollution in the air in their community. They discuss their results to end the lesson.

Students collect air samples to test it for air pollution. They are read the story The Lorax and discuss the effects of air pollution. They share their observations with the class.

Students work together to design and implement an experiment on friction. They test to see if contact area affects the amount of friction. They discover how engineers use friction to make certain products better.

Young scholars watch the program "Pieces of Mind" from PBS and participate in a class discussion about PET scans and their advantages. Students then brainstorm activities a PET scan could be used for.

Young scholars create a Patient's Rights Charter after discussions of past experiments with such rights charters using the biographical posters in order to stimulate discussions on current attempts to create a Patient's Rights Charter....

Students pour water into a "magic" box and examine how it comes out with a much larger volume of water. They, working in small groups, design a volume exchanger and explain its design to the whole class.

Students are given a fictitious case study to read in preparation for the class. This activity can also be readily adapted for a role-playing classroom exercise. They discuss the ethical issues of the case.

Fourth graders examine how the use of chemicals may affect the environment and how their are many different political issues surrounding chemical usage and the environment. They research different newspapers and magazines about the issues.

Fourth graders, in pairs, explore the relationship between a star's life and its mass. They use a concept map to illustration the three categories of stars.

Students gather air samples using a particulate air monitoring card. They investigate the variable that influence the amount of particles that they collect.

Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

Students explain that particle movement changes as a substance changes from one phase to another phase.

Students work in groups and observe chemical reactions inside zip-lock bags. They use all of their senses, except taste, to observe the reactions.

First graders investigate the changing states of water.

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...

Bored with frog and earthworm dissections? Had your fill of fetal pigs? Anatomy young scholars will be intrigued by the sheep's brain, and you will be prepared with guiding questions, extension activities, and pictures as they dissect...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other...

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson has streaming video, resource links to access, and a good hands-on activity that is clearly described in the...

How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Earth's magnetic poles switch positions about every 200,000—300,000 years. In the activity, groups create a planet with a magnetic field. Once made, they use a magnetometer to determine the orientation of the planet's magnetic field....
