Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

After hearing about the 2006 PHAEDRA mission that explored the Aegean Sea, middle schoolers work in groups to create a robotic vehicle. They must consider power, propulsion, and other vital systems. Use the multitude of external...

Earth science experts learn about the roles of nitrogen by taking a virtual journey through the nitrogen cycle. Completing a passport worksheet along the way, they move from place to place around the classroom by the toss of dice. Each...

Junior oceanographers and underwater geologists describe the four major steps of mass spectrometry. They compete in small groups to simulate the tracking of a deepwater methane plume using imaginary autonomous underwater vehicles. Give...

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized lesson...

Students explore how the innovations in culture and technology influenced the development of a leisure industry in America at the turn of the twentieth century.

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Pre-schoolers gain a better understanding of personal space by playing this modified version of musical chairs. Played like musical chairs, students circle around a ring of hula hoops as music plays. When the music stops everyone needs...

Everybody loves video day! Grab your class's attention with this well-designed and engaging resource about graphing. The video introduces a scenario that will be graphed with a piecewise function, then makes a connection to domain...

Investigate invisible forces. Young engineers design a setup that changes the direction of a steel ball using a magnetic force. The purpose of the setup is to model the gravitational pull of spacecraft by planetary bodies.

A lesson involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Students view the film 'Black Robe,' which further develop students' abilities to see an event or era of history from multiple perspectives. After the movie, they utilize worksheets imbedded in this plan to write about what they've seen.

There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers. 

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

Third graders experience optic illusions by creating flipbooks. In this optics lesson, 3rd graders view a demonstration of the workings of rods and cones using a camera. They are shown an optical illusion and work to create their own...

Using the Hudson River as the focus, learners discuss the difference between salt water and fresh water environments, analyze maps and graphs, and complete addition and subtraction problems. This lesson comes with a wealth of...

This line dance lesson involves the use of PE equipment. If you have yoga balls and rhythm sticks then take a look at this lesson. Of course there are other things that could be used instead of yoga balls. This is a 48-count dance...

Looking for a fresh approach to an end-of-unit project for The Odyssey? Check out a resource that has class members write their own hero's journey short story and then craft an illustration that depicts their tale. Apollonio di...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

Students apply abstract concepts, such as stress, fulcrums, the law of gravity, and the strength of different geometric shapes. Groups of student contractors operate simulated architectural firms to create strong, economical bridges.

Inform your class about the adaptations in fish eyes: cones, lens size, endothermy, and speed of vision. The adaptations are related to diving behavior. Junior marine scientists compare the adaptations of four different fish species to...
