A colorful and comprehensive PowerPoint highlights this lesson on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how compact discs work...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

Students explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and design a machine that will stay in motion for the greatest period of time.

Students investigate properties of common molecules. In this chemistry lesson, students construct polymer models to gain a better understanding of the properties of polymers.

Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....

The goal of this science activity is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

What is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

Breakwaters offer marinas and beaches protection from large ocean waves, but how do they work? Scholars observe wave patterns and wave amplitude during the simulation. They control the number of openings, width of openings, distance...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

Students, in cooperative groups, design and create a wildflower garden for the community. They write letters to property owners requesting use of their land and then write invitations to their parents and to local, state, and federal...

Students identify the properties of a magnet. In this physics lesson, 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, paper,...

Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

Challenge young mathematicians' understanding of symmetry. Provided with images of different shapes, letters, and national flags, students are tasked with identifying the lines of symmetry and order of rotational symmetry...

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

What's life like aboard an ocean exploration vessel? Junior oceanographers examine the important role of communication in ocean research in lesson two of a five-part series from NOAA. The materials introduce the class to life on...

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Student observe the effect soap (or detergent) has on the movement of food color in milk. Pupils observe the properties of solids and liquids while making butter. They read a poem, Shaking, and listen for ryhming words. Studdents...

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

Examine the science behind computer communication. After defining the properties of magnets, learners simulate how a computer hard drive works by sending each other binary codes using the magnets. They use these communications to...

Fifth graders study the concept of momentum and its application by Newton in his studies. They view a demonstration and complete an experiment with toy cars on a racetrack that shows them the properties of momentum and how velocity and...
