Hello my wonderful students!!! Listen closely...are you listening??? This is your science teacher Ms. Yates. I know, I know. I just saw you a few hours ago. Remember the awesome reminders, updates, and fantasticness that I promised you?? It is here. Yep!! Right here. Remember to check it out daily. The rewards will be worth your time. Assignments that you forgot about or were absent for? Here!! Notes you may have missed?? Here too!!! Announcements?? Yep!! And, fantastic reminders of all the cool stuff we did today...All here and more!! See you tomorrow. Or Monday, if you are so awesome that you are reading this over the weekend.

Siege Machines
What type of motion will your marshmallows experience? What will be the source of the forces involved? What will you need to take into consideration when launching your marshmallow? Do you predict you will be "king of the castles"?
Reasons why team A+AJ will win (I'm N-Dru) 1. We built a gunslinger cannonarm with dynamic distance adjusters. The trajectory is controlled by two movements, the tightness of a clip connecting the spoon the popsicle sticks and a rubber band controlling speed. 2. Dynamic aim allows whatever is needed, from bullet to lob city, which is controlled by the height from the popsicle sticks to the ground when stagnant
The forces in play are inertia, friction, trajectory as well as pure design
BTW - I have a sister so the rubber band, ponytail, girl's advantage kinda applies to me as well
This is one of my favorite challenges this year. it's no bueno that my partner Troy won't watch our spoon thingy kick butt in the competition tomorrow. oh well... ~Michaela
The marshmallow will be in a fluid motion because it is in air. It might also be static because it is being thrown so there is that pause wit the spoon and the marshmallow. The forces acting on the objects is gravity and air resistance. Gravity is stronger than air resistance so the objects are on the ground. The marshmallow will be in projectile motion once it is launched. You have to take in to consideration how far back you need to launch the marshmallow and the direction it is in. You also need to keep in mind the farthest and shortest distances you can launch the marshmallow so you know what how far back to hold the spoon. Also keep in mind that marshmallows stick sometimes to the spoon. I think we might have a chance of getting King of the Castle, but I think it mostly depends on who we are up against and if we are able to easily master acceleration. Nicole
It will experience the arch motion, or a baseball player throwing a ball. The forces are gravity and acceleration. I will take into consideration how far I need to pull back the spoon and how big I need to build the castle. I think Nicole and I will win. -Riley
Marshmallow- fluid motion/static motion What to keep in mind- If the spoon goes too far forward the marshmallow will launch at the ground WE WILL BE THE KING OF THE CASTLE!!!
there will be tension force and I have to account for velocity. I think we will be king of castles
ReplyDeletethis is so much fun!!! sorry but i think nicole and i are going to win:)
ReplyDeleteThis was amazingly hard, I thought that it was going to be a lot easier, next time I won't underestimate the power of the marshmallow. -Hanna

This was a very difficult challenge because my teams catapult either broke or did not shoot the marshmallow. I hope we win. sammy

playing stealthy is healthy and my cataput will stealthalize the playing field with a great use of gravity and inursha.
ReplyDeleteI Nicole believe I will destroy everyone. Just kidding! :)
