ROCKET SODA TV

I ask the student to hold out both hands in front than i do the same. I longboard as a hobby but i act like I've never stood on one. I'm not a big guy but usually the size discrepancy is pretty obvious. I put the student on one skateboard and i stand on the other. facing each other and about 2 feet apart. I like to demonstrate this by pulling up the smallest kid in the class. the more force it takes to accelerate it' or you could say. The first law i teach about is Newtons 2nd Law. The kids are ready to build but first you can do a fun demo. Hot glue and Hot Glue guns (not e below) I supply basic tools and tape to build the rocket with. I ask the kids to bring bottles, long cardboard tubes, cardboard, coroplast and any packing material they will need. whatever you can make up :-) Make sure they draw the fins to size and they are being realistic about the egg and how it will get into the hatch. You'll get a couple groups that finish the drawing in minutes. Spend the remaining time working on design. You can trace out a bottle or two which helps them visualize it. I pull out the paper and teach them about drawing objects to scale on the paper. you always get at least one kid who is left in the cold. Once the kids are ready i break them into groups of 2 or 3. better than mine! My only stipulation is that they have to make an escape hatch that can be used to insert and remove the Eggstronaut on the field. Go over padding and protection if you want but i find the kids come up with the most amazing ideas. Explain that if the passenger survives they will get extra marks. A good size is a triangle with Hypotenuse of 3-7 inches and bottom edge of 1-3 inches is good. explain that the rockets explode off at more than 100kph and large fins will rip off. (tubes, extra bottles)įins that are Symmetrical with 2-4 are best. Suggest methods of lengthening the rocket. (more on the water next day) This is important because the 'Booster Bottle' which is pressurized ****MUST**** be a bottle for carbonated drinks and MUST MUST NOT be punctured or cut AT ALL. The rockets fly by pressurizing air with water. I cover each of these points on the board. not impressive but works fine.Īfter you show the kids examples from the web they will be hard to hold back.

I use a TV attached to my ancient computer. a computer with examples of water-bottle rockets from the web. Metersticks (yardsticks for the people south of me ) :-) (i cut stuff off a roll from the art guys.) I'll also provide a marking sheet at the end so you can use it in your class. Cardboard or coroplast (the stuff cheap signs are made of) 2 liter pop bottles (NOT water bottles!) get at least 2 of them The students will learn to use basic tools to construct a working project. By building a simple Rocket the students will understand these laws in a way that makes sense to them AND they will learn to think creatively, design and problem solve while building a basic design. Students will learn to tell the difference between MASS and SIZE Once things start moving they tend to keep moving until something happens to change how it is moving' 'stuff that is sitting there will stay that way unless something happens to it. 'F=MA' or to make it so I can understand. The students will understand Newtons First Law of Motion.

'if you push something it will push back' 'To every action there is an equal and opposite reaction' or you could say. The students will learn and apply the basic principles of Newtons Third Law of Motion. The students will learn and apply Newtons Second Law of Motion in a way that makes sense to them. you can max the pressure like crazy, too. I have seen all sorts of designs but I'm hoping to come up with something as effective as the commercial one above.Ī good hand pump works well but a compressor REALLY makes life easy. I will design and build a launcher and do an instructable in a few weeks when I get a chance. i've added a couple of pics of it below as well. You'll need the basic materials listed below as well as a launcher. the Eggstronaut, which is an egg that if survives will award extra marks to the team. You add water, pressurized air and using these instructions you'll get height that you and your students will not believe. This rocket is based on the usual 2 liter pop bottle you find at grocery stores. Just follow through a day in advance and you'll have kids learning so much more than anyone bargained for. At the top of each day you'll find a list of tools and materials. Each step in the Instructable will be a day in the class. I've seen all sorts of Water Bottle Rockets on Instructables and while surfing the web but I thought an Instructable with the step-by-step process of building a whole bunch of them with a class of grade six kids would be good.
