On Earth, we have a force known as gravity, measured at 1 G. In space, astronauts are faced with the challenge of zero gravity. This poses quite a few problems for space engineers. The normal everyday inventions such as toilets, chairs, drinking straws, and shelves all depend upon gravity to work normally. Engineers must design equipment to function in a zero gravity environment. A major problem for space engineers is cost. It costs nearly $5,000 per pound to launch a shuttle into space, so weight is a factor when designing shuttles and tools. Other problems for space engineers are: limited power, water, space, and lack of garbage facilities. To address these problems, space engineers use lightweight materials such as dental wire, wet wipes, and battery-powered tools. Packaging is kept to a minimum to reduce waste on the shuttles. In this Webquest,
students work in teams to design an m&m dispenser that would work in
space to combat the lack of gravity, that is lightweight, and compact in
size.

Have you ever wondered what life is like on a space shuttle or on the space station? Astronauts do many of the same things you do everyday - such as sleep, eat, wash, play, and even go to the bathroom! The only difference is that in space there is no gravity, so astronauts must use special equipment to do these everyday tasks. What is gravity? Watch this BrainPOP movie to find out! Everything on Earth relies on gravity to work properly. Look at your desk. Why is everything laying on it? Gravity holds all your papers, books, and pencils in place. Earth toilets rely on gravity to flush. Space toilets use suction (like a vacuum cleaner). The ink flows out of your pens onto your paper on Earth. Pens are pressurized like spray cans to work in space. You don't need a bed in space - just straps to keep you tied to a wall. Instead of using cups to drink from, astronauts squeeze fluid-filled bags with tubes into their mouths. But what about
eating small candies like m&ms in space? You can't dump the bag
out into your hand - the m&ms would fly everywhere! So, what
would you do? You'd need a zero-gravity dispenser. Where would
you get one? You'd need to invent one!

1. First, watch the BrainPOP movie to learn about gravity. What questions do you have about eating in space, where there is no gravity? 2. Use the Internet Resources to find the answers to your questions about astronauts and their food in space. Record your findings on an Idea Web created using Inspiration software. Be sure to organize your web in a way that makes sense to you. 3. How do m&ms act? Make observations of the physical properties of m&ms. How would they act in space, a zero gravity environment? 4. How could you design an m&m dispenser that would work in space? Become a member of the "NASA m&m Dispenser Designer 2002 Team." With your partner, create a plan for a design for an m&m dispenser that works without relying on gravity. What materials could be used to make your dispenser? Is it lightweight and cost effective? 5. As a class, create a list of attributes for the "perfect" m&m dispenser. Share your design with other design teams. Compare other designs to the list of perfect attributes. Offer suggestions for improvement to other teams. Make improvements to your own design. 6. Build a working prototype of your design. 7. Create an advertisement for your m&m dispenser. Include a digital camera picture and a scanned image of your design in the advertisement. 8. Write
a business letter to NASA to share your invention with space engineers.

You will be evaluated on the following: 1. Your level of cooperation and participation. 2. The neatness, completeness, and quality of information gathered from your research and displayed: on your Inspiration Web. 3. Your ability to incorporate what you have learned about gravity and space foods to create a model of an m&m dispenser that would work on the space shuttle. A
Rubric
will be used to grade your project.

Your successful creation of an m&m dispenser that works in a zero gravity environment, puts you well on your way to someday becoming a space engineer. Perhaps NASA will like your idea so much that you will see your invention on the next space shuttle mission! |
