Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

How can a robot measure the length of something when we don't know how far the camera is from the object? The lesson explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Third graders are introduced to the importance of science safety. As a class, they role play through different safety procedures and decide which senses need to be protected for different scenerios. They discuss how to avoid hazardous...

Ping, ping, ping. The last installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explores technology use in marine studies, such as sonar. Activity involves simulating sonar techniques to identify a...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Students practice analyzing skeletal remains for clues by using the Internet.  In this scientific investigation instructional activity, students research the La Belle shipwreck using the Internet and written materials, later...

Learners solve an environmental problem on a local river. They use their knowledge of river ecology to develop an action plan. They use river-monitoring equipment to collect river- monitoring data, including biological, physical, and...

Young scholars acquaint with co-participants and identify the practice basic compass functions and orienteering procedures. They also work together to solve a small challenge. Students then identify how the challenge of orienteering...

Students listen to the story "The Great Kapok" then discuss characteristics of the rain forest. They make several different types of rain forest animals from paper plates (ex. sloth, tigers, monkeys etc) and design costumes for a...

Students explore the Earth and its rotation. Volunteers model the sun-Earth system to demonstrate that the Earth rotates around the sun. In groups, students simulate "traveling" around the sun and discuss when it is night and day.
