Building a Lunar lander. LO: To design, test, and evaluate a space lander. 1) How long does it take Earth to rotate on its axis: A- 24 hours B- 27 days C- 365 days 2) How long does it take Earth to orbit the Sun? A- 24 hours B- 27 days C- 365 days 4) What is the International space station? A- Refuelling station for spacecraft B- Collection of international satellites C- Space laboratory shared by several countries. 5) Give one advantage and one disadvantage of a manned space mission. 6) Give one advantage and one disadvantage of an unmanned space mission. 3) How long does it take the moon to orbit the Earth? A- 24 hours Extension: explain why some people are B- 27 days both for and against space exploration. C- 365 days Building a Lunar lander.

C- 365 days Luna Lander • Landing spacecraft is tricky. • Travel 24,816 miles per hour. • To land gently, these spacecraft need to slow down before touching the surface! And if there are astronauts on board, the lander needs to keep them safe, too. 1. Each team of three students will build its own lander capsule, designed to land within the target zone. 2. Choose the parachute and packaging material you will use around the egg. Design and build your lander. Attach the parachute. 3. Record the time it takes for the egg lander to reach the ground. • A drop is successful if the egg does not crack. Data and Results 1. List the packaging material used. Which material and packing technique worked the best? 2. Draw your design. 3. Time of the fall s
