In this activity, participants will imagine the challenges and opportunities of asteroid mining. Participants will draw their own asteroid mining machines, and consider how these devices would extract, process, and return mined materials to Earth. They can also assume roles assigned by the activity's challenge cards, and imagine what concerns or priorities they might have as a scientist, explorer, lawyer, or engineer. While the technologies necessary for mining materials from asteroids do not yet exist, current missions exploring and studying asteroids may lay the groundwork for future asteroid mining operations. Educators should begin with the file named: Asteroid Mining - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

In this activity, participants explore the concept of apparent size and experience this phenomenon using familiar objects—a tennis ball and a beach ball. Participants learn that the Sun and Moon appear the same size in our sky because although the Sun is much bigger than the Moon, it is also much farther away. Both English and Spanish activity resources are included. Educators should begin with the file named: Big Sun, Small Moon - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

In this activity, participants investigate a frozen sphere, trying to learn about objects hidden inside. Participants learn that planetary scientists at NASA are investigating "icy worlds" in the outer solar system, looking for evidence of liquid water and possible signs of life beneath the icy surface.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

In this activity, participants imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it. They learn that NASA scientists study extremophiles on Earth to imagine the variety of life that might exist elsewhere, and make predictions about where to look for it. Both English and Spanish activity resources are included. Educators should begin with the file named: Imagining Life - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner. Because of the unique quantities and locations of the materials and the forces that spread them out, each model nebula will be unique—just like each real nebula! Both English and Spanish activity resources are included. Educators should begin with the file named: Nebula Spin Art - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: .

In this activity, participants explore the complex but predictable ways objects in the universe interact with each other. Stars, planets, moons, and other objects in space orbit around each other because of gravity, and NASA scientists can use what we already know about the laws of physics to make new discoveries and predictions. Participants in this activity use orbiting clay balls to make simple, functioning models of interacting objects in space. Both English and Spanish activity resources are included. Educators should begin with the file named: Objects in Motion - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

Join Tarissa and Sabrina as they measure and compare the volume of different sounds across New York City in this video from DragonflyTV.

In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.

Students perform many inquiry activities related to Earth's orbit. Included are recording daily temperatures, observing the sun's path over several weeks, tracking sunrise and sunset times, and angle of sunlight. Diagrams make lessons easy to follow.

Provides nine interactive, online practice tests for the fourth grade Florida Comprehensive Assessment Test (FCAT). Each test uses a number of reading skills and uses both multiple choice questions and short written responses. It provides immediate feedback to the multiple choice questions as well as sample answers to the written responses. Although this test is specific to Florida, many of the skills it covers apply to reading in any setting.

In this lesson designed to enhance literacy skills, students explore brain injuries called concussions: what they are, how they occur, the challenges in diagnosing them, and ways to protect yourself from them.

This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.

In this video from Common Ground and Cleaner Water, Tribby Vice, a Kentucky farmer, talks about the changes he has made on his farm to protect the water quality of the stream running through his property and the watershed in which he lives.

In this video segment adapted from NOVA scienceNOW, scientists in western Greenland explain how a glacier there is shrinking and moving faster due to increased melting.

In this video from Nature, watch how ravensŰ__Ű__ŒŒÇ smarts can be observed in many situations, such as when they hunt and store food.

The third paragraph pinpoints the importance of hyperons in particle research. Hyperons and neutrinos share characteristics of the weak force. Complex stuff, but the real deal. Parts of this report may be very useful. Many photos, slow to arrive.
