Color me green. The fourth lesson in a unit of 15 introduces the class to color images and how to encode color images using binary code and hexadecimal numbers — and they will quickly notice that it is easier to code the...

Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Build an interest and appreciation for architecture in your young learners with this fun 10-lesson art unit. Engaging children in using their five senses, the class first observes the environment around them, paying...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Where does bad light end up? In a prism! The presentation covers light, mirrors, lenses, and the structure of the eye. It also provides explanations of reflection, refraction, concave and convex mirrors and lenses, and a comparison of...

Five steps walk scholars through the process of drawing a Monarch butterfly. Participants research the insect, make observations, trace, then color. 

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth instructional activity of an 11-part series. Individuals then...

Three astronomy activities in one resource! Here you will find one hands-on activity, one demonstration, both with discussion questions, and one activity worksheet. During these lessons young scientists discuss how stars are...

The Sierra Mountains in Nevada and the Tetons in Wyoming originally formed as fault block mountains. In order to visualize these fault blocks, pupils use construction paper to create layers of earth. They cut the paper models and form...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Horses come in all shapes and sizes, but all belong to the same species. Young scholars explore the different traits and connect the information to genetic modification. The interactive gives them the option to read about 18 different...

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

Balance scales create a strong visual of how an individual prioritizes one's self alongside their commitments to the community, school, and home. Scholars complete a graphic organizer then discuss their findings with their peers. A...

Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

Using this resource, your team of green thumbs discuss why plants are a part of a healthy diet and the different ways they are used in daily life. They then observe the characteristics of different seed as they attempt to match...

Site explores colors and how they are formed. Provides three different activities to explore color.

Try making words on the screen disappear by changing the background color of this page. Add or subtract red, green, or blue, and see how light is made up of many different colors.

Test your knowledge of light, sound, and color with these practice science questions.
