The best learning environment is a safe learning environment. Remind young scientists about safety rules and regulations in the science lab, the classroom, and the field.

The cycle of energy is important to many different systems on Earth. Scholars use questioning and observation to investigate the differences between renewable and non-renewable resources and how they relate to global changes. They...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Take a field trip with water as it moves on and below Earth's surface. Investigators discover the link between water and land in the water cycle and the importance of watersheds while viewing an animated video. Scholars test their...

Explore the states of matter without the mess or expensive equipment in a compact, informative activity. Scientists watch as the narrator explains the three states of matter using a glass of ice and soda in an animated video that...

Learn why what goes up must come down in both air and liquids. Investigators discover how convection transfers thermal energy and the movement of particles in liquids and gases due to density differences by viewing an animated video....

Take a trip into outer space from the safety of your classroom. A great addition to the digital library of any science teacher, this reference offers a behind-the-scenes look at the research going at the International...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Is it possible to outrun a tsunami? After watching a presentation that explains how waves and tsunamis occur, class members investigate the speed of tsunamis triggered by an earthquake.
