Thrust Structure

Maddy and Anja Robotix X

Today me and Anja did a lab called Robotix X where we had to make a robot that actually worked. Not only that, but make it pick up something with robotic arms and move it somewhere and drop it but then back up into it's original spot.

It doesn't really have a law that applies to it, though because we used controls to move it, not our hands. : ) Today was really fun and probably my favorite lab.

Me and Anja work well together.

Our first try worked! YEAH!

thanks

Launching to the moon

After you watched my video you probably had a few questions. :) So the law that applied to our experiment was Newton's 3rd law. Because the air (and spit) in the balloon shot out the back and the balloon excelled forward and (hopefully) hit the wall with some force. So if you watch our video again you can see. I learned that the more air in the balloon the faster it will go and the more likely it will hit the wall. YEH!

Me and Gabby's Africa Quiz

Lab #2

My partner was Lilly and we had to make a successfull parachute that was flying or drifting above a hair dryer and when you drop it from a tall height.

The way we built it was with four really, really long string, a little army man and about 5-6" by 5-6" plastic sheet from a garbage bag. We put a hole in the top that was only about an 1". It was perfect! We were so excited and it worked really well, it was our third time trying to make a successfull one. YAH!

I learned that when you don't have a hole in the top, your parachute will twist and turn on it's way down from falling, and not work with the hair dryer.

It was really fun!

Pathfinders

oh my gosh! i am so happy i get to go!

Maddy and Friends on Moon

So one day Maddy was playing softball with her friends from her hometown, Indianola; Ashley, Ian, Riley and Ross. They all were playing softball when Riley said, "Hey! I just noticed something. When Ian pitched the ball, i saw that it went slower than it did back home!" Ross replied with "Oh my goodness! Your right! Well, the acceleration due to gravity here on the moon is only
1.6 m/s2 and at home the acceleration due to gravity is about 9.8 m/s2! Which means the Moon is pulling the ball down much less!" Ashley looked a little confused and I explained, "You see Ashley, gravity pulls things towards the conter of the Earth. So if there is more gravity at Earth, things would come down a lot harder. But on the moon, it has less gravity, so-"

"It pulls you with less force!" I think Ashley gets it.

LAB #1 LEGO ROBOTICS

Today in labs we worked on lego robotics as our first lab. My partners were Taryn and Sam and we had to get a lego-bot car-thing to push, pull, or drag a lego rock into a very small square using a computer program called ROBOTICS. You controll the car things to turn, go, stop, drag, and lots of other things using this ROBOTICS program. We did okay in the begining, actually, we didn't do that hot! We tried 4 times and by the last time, it was like a 1/2 inch away! and we never got another chance.

i learned how to work with others in a project that is kind of meant for an individual worker. I learned that even the slightest change can chane the entire motion of the car.

My question is how does the car thing know what to do?


thank you!
