https://www.youtube.com/watch?v=LSzr4zX_RG8 this video is a differejnt type of video as the ones before. this video would help me on making a small type of robot. robotics aint that hard to make but you have to be smart. you would also need to have some advance materials. you would probably need a special help by your teacher if you under age. this video was a good reference to my project. because it have some easy steps.

https://www.youtube.com/watch?v=Ospa8O0lFXo this video dont really tell me much but thats because this is not the project ama be working on. am only putting this video link because i might change my mind. this video then would be very heplfull. after i change my mind i would probably change my mind again. that would be because making a jet would be more easy. all the videos would look easy until i actually work on them. after i do that then we would see if it was easy. if non of my inventions work i think ama give up. this robot would need a lot of materials to make because its more advance. the only think i got out this video was on how accurate you have to be.

3d model of a jet plane made by cans

https://www.youtube.com/watch?v=DTjxcdWf-18 This video would be my main video ill be using. this video have explain me all the steps i would need to build my jet. the dude who made the video had a great idea on how to make a jet. i believe i would only be using at least five cans. since am new to the procces ill probably would need more than five cans. this proccess would take some time to get it right, but this video is a great source to use to create my jet out of cans. i believe that since am good with cutting and putting thing together. ill be more advance in doing this project but i cant get so confident because am alone in this project. that dont really matter because am capable to do it in a short time. and with this video i think ama do great but 0nly if i keep focus. this project would be an obstacle but lets hope this video help a lot.

3 different hovercraft videos posted by my classmate

well today i watched some of the videos that my fellow classmates uploaded on their blog. some of them were just the exact ones i had but i didnt mind because i knew this would happen. after all i saw some videos dat i really liked but i could post them on my blog because they already had them but i still learned a little more from their videos than what i learned from mine. i saw some videos with some pretty good hovercraft but i still have some questions like how do they make it go in a single direction?, because they all go some form of way they dont ever just go in one direction but i saw some some competions in one video that one of my classmate had and it seems like it moves a lot but it only moves when he moves his body in some form of way.

this videos were a good reference for the hovercraft project. i beleave that with the matwerials that we have gathered in all three videos we can succed in making our hovercraft. some of the videos were not as detailed so i found the videos that would help me and my group. the best video i found was from these old dude who made one and it actually worked and after he showed us how to create one step by step. i think that we could make a good hovercraft but i belive that we need to have more than one month because the people on these videos do not look like they took one month they probably took like mare than two to three month to build a good working hovercraft. we might finish on time but were not sure it will work perfectly. but it will work at one time.

conclusion for the roller coaster

*What factor do you think affects the amount of potential energy the roller coaster will have? often referred to as energy of position, is very simple.
*What do you think is the safest way to "come down" from the first hill? i believe it should be like a down ward slope.
*How do you think the roller coaster should exit from the first hill? i believe we should go in a low slope.
*What do you think the height of the second hill should be? i think it should be like at least 70 meters (230 feet).
*What shape do you think the loop should be? (Parabola, elliptical, square...etc)- i think like A perfect circle, 35 meters high.
