Winter Vacation Home Work (December 2016)

Subject: Maths 

Task : Design a system to protect an egg from cracking or breaking from high fall

SOFT LANDING:

1. IDENTIFY THE PROBLEM AND BRAINSTORM:
􀁲 How will you make a frame that holds the egg?
􀁲 How will you attach balloons to your frame?
􀁲 How should you arrange the airbags to absorb shock?
2. DESIGN AND BUILD:
Use the materials to invent your own design.
3. MATERIALS (PER LANDER):
􀁲 2 hard boiled eggs
􀁲 10 nine-inch balloons
􀁲 10 craft sticks
􀁲 8 small (i.e., ¾ inch) binder clips
􀁲 20 assorted rubber bands
􀁲 2 small paper cups (3-ounce)
􀁲 Tape (any kind)

􀁲 1 meter (39 inches) string

WORDS TO USE:

 Force: A push or a pull 

Shock Absorber: Absorbs the energy of an impact
4. TEST:
􀁲 Drop your lander from a height of 1 meter (39 inches).
􀁲 Watch how it bounces and rolls. Did the egg break?
5. EVALUATE AND REDESIGN:
􀁲 How well did the egg stay in the frame? 
􀁲 How well do the balloons stay together to protect the egg on all sides?
6. TRY THIS NEXT!:
􀁲 Drop the lander from 2 meters (78 inches). How high can you go?
􀁲 Add a parachute or other system to slow the lander before it hitsthe ground.

NASA EXPLORES SPACE:

This picture shows NASA engineers testing an airbaglanding
system on Earth. Three rovers have used this
system to land safely on Mars. As they approach
Mars, they’re going about 20,000 kilometers (12,000
miles) per hour. Thanks to a parachute, heat shield,
and rockets, the airbag-wrapped rovers hit the surface
going about 80 kilometers (50 miles) per hour. One
bounced as high as a five-story building. Then after
15 bounces, it stopped rolling, the airbags deflated,
and the mission began.The Curiosity rover is on Mars, studying the Martian
climate and geology and looking for substances
associated with life. Curiosity is the size of a small car.
It is so big and heavy—about five times larger than
earlier rovers—that it couldn’t use an airbag-landing
system. Instead, it used a rocket-propelled sky-crane
that lowered it gently to the surface.
