You will be introduced to the major disciplines of crime investigation as you try to solve a murder through the eyes of the detectives, from examining the crime scene to collecting evidence, wound and blood analysis, document analysis and toxicology.
Scientific theories (proposed descriptions or explanations) have to be testable so that scientists can use the scientific method to see if they are correct. Watch this video about scientific theories and then try the quiz.
Experience the engineering design process as an aerospace engineer assigned to design and test an airplane. Determine which wing and engine configuration is best suited to each mission. Find airworthy, low-cost, and fuel-efficient designs.
Can you build a plane? First, go to the Wrights' workshop and try some of the tools and tests the Wrights used for bicycle manufacturing and engineering. Design and fly the world's flying machine. Once you've designed the aircraft, you can take it to Kitty Hawk and test it in a 3D flight simulation.
This is a virtual tour of the closest stars to our own Sun. It's very interactive; you can click, drag and zoom with your mouse. You may want to visit the top left corner and Take a Tour to get started.
BBC shares some perspective about how big our solar system is. Scroll down the screen to move your rocket away from earth. Note the measurement at the bottom of the screen, giving you a pixel to metre or kilometre ratio.
This 12-minute video explains how our solar system works, focusing on how astronomers have searched for other stars and planets. Astronomers think there may be many billions of Earth-like planets in our galaxy.
Do you know Mars from a meteorite or stars from satellites? Test your knowledge of the planets and the sun with this quiz. If you have trouble with the quiz, you can explore the encyclopedia to find the answers.
This site is a 3-D environment full of real NASA mission data. Students can "explore the cosmos" from their computer. "Hop on an asteroid. Fly with NASA's Voyager 2 spacecraft. See the entire solar system moving in real time." (NASA description)
This site has information about each planet and moon in our solar system with many pictures of each planet, discussion of the history of its discovery and exploration, and its physical characteristics. In addition to the planets, there are also pages about the Sun, moons, asteroids and more.
Watch the Earth move around the sun during the seasons of the year. This interactive uses the examples of Boston and Miami to illustrate how different cities get different amounts of sunlight and heat through the year.
Have you ever looked up at the stars and felt small? Have you ever looked thought that our Earth or the Moon are large? This video gives an interesting perspective on the size of our tiny planet among the known large stars and galaxies.
This video explains how the shape of the Earth's orbit around the Sun and the Earth's tilt on its axis affect the amount of sunlight we get in winter and summer. Learn about Kepler's discoveries and how they explain the seasons.
This animated video shares the story of the very first asteroid ever discovered and explains how asteroid hunters search for these celestial bodies. Learn how astronomers find asteroids and how they tell the asteroids apart.
The Tree story provides short video clips on the growth of trees, how trees adapt to their environment and the impact mankind has on trees. Choose from "the Living Tree", "From Root to Crown" or "The Tree Story".
