Today we tried to capture the motion of a falling coffee filter with motion sensors, however, we were unable to get clean graphs. We will try one more time tomorrow.

Today we began task 2 of our project. We brainstormed ideas for what data we could collect to understand and design the best parachute. We then began to look at the motion of a coffee filter. Monday we will actually create a velocity time graph for a falling coffee filter using the computer sensors. The analysis of this graph will help us to understand air resistance.
Your task 1 project log was due today. If you forgot to hand it in, please do so on Monday. I also received several papers without names, so you may have a 0 for the assignment even though you handed it in. Your landers should be finished, and you should have a scale drawing of your design (top view and side view OR a 3-d view) with all dimensions labeled in your project log. Make sure you complete the rest of the project log (task 1 :Research Mars Landings) - it will be collected tomorrow.
Today we began building our landers for our eggstronauts. We will finish building tomorrow and begin learning about air resistance and parachute design.
Today 1st and 2nd periods launched their projectiles on the football field (6th period launched theirs yesterday.) There is no lab writeup for this activity.
Then we looked at several NASA missions to Mars to try to identify similarities/differences between the EDL systems of these missions. Tomorrow you will build your landers to hold your 4 egg-stronauts. Today we learned about our project: Mission to Mars. We learned about our project goals, and discussed at a high level what we are going to accomplish by the end of the project.
Today was supposed to be launch day. We tried launching projectiles in first period, but it was so windy that the rockets didn't go very far. We will try to find a more agreeable launch window in the next few days. Sorry!
Next week we will begin our last unit in mechanics. This unit will be based on a project involving landing astronauts on Mars. Today you used the chromebooks to research interesting facts and tidbits about Mars.
Tomorrow we launch our rockets, so make sure to bring a jacket as we will be outside! Our "final" exam will be on Tuesday 1/17. This exam will close out our forces unit and will only cover friction and tension. The solutions to the friction WS and the friction/tension review WS are available in the google drive folder for this unit.
Today we played with pulleys and began solving problems involving tension.
