Two virtual labs offer practice for creating your own or science project: "How Does Your Garden Grow" and "Critters!" Learn how investigations are conducted from the first step to the finished product.

From a 1954 article in American Heritage Magazine, this interesting account shows how the outcome the Battle of Ball's Bluff had important political implications. Read about how the powerful Joint Committee on the Conduct of the War...

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out...

Nervous system messages are sent as electrical signals along the length of axons and dissolved salts are important for electrical signaling in cells. In this lesson students are introduced to this concept by creating an electrical...

In this lesson, students will first discuss where energy comes from, including sources such as fossil fuels, nuclear, and such renewable technologies as solar. After this initial exploration, students will investigate the three main...

The Applied Science resource consists of practical activities that demonstrate the importance of standard procedures in scientific work. Students analyze qualitative data through a variety of activities. Some topics investigated are...

Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.

Students learn about the nature of thermal energy, temperature and how materials store thermal energy. They discuss the difference between conduction, convection and radiation of thermal energy, and complete activities in which they...

Investigate how scientists conduct scientific research or solve scientific problems to impact the future.

Lesson focuses on the Plants in Space experiment which studied how plant roots developed in a weightless environment. Students will conduct three scientific investigations to learn how light, gravity and microgravity affect the growth of...

Students are given a scenario for this instructional activity where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an...

Young scholars conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet,...

In this lesson, students conduct heat transfer experiments to investigate why the Earth is still hot at its core, even after billions of years since its formation. They will learn that the rate of heat transfer is dependent on an...
