Unplugging from technology for one day per week will decrease your carbon footprint—are you up to the challenge? Part two in a series of three allows individuals to explore their personal carbon footprints. By first taking a quiz at home...

There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

Part two in a series of four explores the effects of climate on succession or the changing of plant species in a forest. Groups review how to identify trees and then spend a day in the field collecting extensive data on trees to...

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Human bodies can conduct electricity—that doesn't sound like it would feel good! Learners explore conductivity through the use of this simulation. They see why metals conduct electricity and plastics don't and why some materials will...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson plan of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids....

Messenger's sun shade measures 8 ft x 6 ft and will have temperatures reaching 700 degree Fahrenheit on the outside while maintaining a cool 70 degrees underneath. In the third activity of four, groups discuss the basic properties of...

The first capacitor was a Leyden jar, invented in 1745. Physics scholars explore capacitors in an engaging simulation. They may view one or set up circuits which contain two to three either in series or parallel. Other views include...

Pupils explore modern batteries and how they work by viewing a simple simulation. It shows electrons moving around the insides and if the voltage is changed, little people move the particles from one end to the other — an entertaining...

Don't be resistant to physics! A simulation shows classes how a resistor works. Change the battery voltage and resistance to show how this affects the flow of electrons. Temperature and amps measurements are shown for the system as...

Radio signals transmitted to Pluto take five hours to reach their destination! In these two activities, young scientists explore data communication in space. In activity one, pupils learn how data is gathered and sent back to Earth....

Scientists have theorized that our solar system formed 4.6 billion years ago. In this pair of activities, learners first hypothesize how our solar system was formed. Using this information, groups then determine how scientists search for...

How does the shell color of crabs and the habitat they live in impact the predator-prey relationship? The fourth instructional activity in a series of five is a game where participants try not to get eaten if they are a prey and try to...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

Pupils learn everything from how to take scientific measurements, to accuracy/precision, to density and a plethora of topics from a presentation on the metric system.

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

Photosynthesis was discovered in the 1770s, but chemosynthesis wasn't discovered until 1977. While many have performed an experiment to show how photosynthesis works, the activity allows pupils to observe chemosynthesis. Scholars set up...
