## How to protect an egg in a bottle rocket

How To Make A Bottle Rocket With An Egg Inside

Dec 06,  · We designed fins made out of cardboard, drawing out a design that we thought would be the most aerodynamic. We then used super glue and watered down flour to paste the fins to our rocket. To make our compartment for the egg, we taped the small top and bottom sections, eventually filling it with cotton and bubble wrap to protect our egg. Results. Our rocket preformed extremely well on . Apr 21,  · If you want to explore the idea of parachutes i suggest using plastic bags cut open and tethered properly. I've had students use a bottle cut in half with the egg attached to the top. The bottle rests on the booster rocket but is not attached. When the rocket is accelerating the egg bottle .

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 protecg six kids would be good. Each step in the Instructable will be a day in the class. At the top of each day you'll find a list of tools and materials. Just follow through a day in advance and you'll have kids learning so much more than anyone bargained for.

This rocket is based on the usual 2 liter pop bottle you find at grocery stores. You add water, pressurized air and using these instructions you'll get height that you and your students will not believe. AND to make it interesting You'll need the basic materials listed below as well as a launcher Here's a link to a commercial version I have seen focket sorts of designs but I'm hoping to come up with something as effective as the commercial one above Learning Objectives: -The students will learn and apply Newtons Second Law of Motion in a way that makes sense to them Once things start moving they tend to keep moving until something happens to change how it is moving" -Students will learn to tell the difference between MASS and SIZE -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 aan a basic design.

Right, then. Lets get started Tools and Materials: -a couple of 2 liter bottles -Big sheets of paper. I use a TV attached to my ancient computer After you show the kids prptect from the web they will be hard to hold back. Its pretty cool. I start asking questions like these: -How does it fly? I cover each of these points btotle the board. What you want to coax out of them is: The rockets fly by pressurizing air with water.

It will explode if otherwise. I've done it and it is really scary. Funny but scary. Long how to win your ex double length work best. Suggest methods of lengthening the rocket. Keep them small A good size is a triangle with Hypotenuse of inches and bottom edge of inches is good. Explain that if the passenger survives they will get extra marks.

They love this. Go over padding and protection if you want but i find the kids come how to get everything back from icloud with the most amazing ideas 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. Once the kids are ready i break them into groups of 2 or 3.

Don't do I pull out the paper and teach them about drawing objects to scale on the paper. You can trace out a bottle or two which helps them visualize it.

Spend the remaining time working on design. You'll get a couple groups that finish the drawing in minutes Spend some time discussing materials.

I ask the kids to bring bottles, long cardboard tubes, cardboard, coroplast and any packing material they will need. Its up to you. I supply basic tools and tape to build the rocket with. The kids are ready to build but first you can do a fun demo. The first law i teach about is Newtons 2nd Law I pull out 2 skateboards. I put the student on one skateboard and i stand on the other.

I'm not a big guy but usually the size discrepancy is pretty obvious. I longboard as a hobby but i act like I've never stood on one. I ask the student to hold out both hands in front than i rgg the same. I ask the class what would happen if we pushed our hands together really hard. Of course the kids know what happens so i gently push on the hands of the student.

Its amazing how far a kid will roll. I won't move more than a couple of inches. I get the kids to notice 2 things. Newtons 2nd law relates to the idea that more massive objects will take more energy to accelerate, or move.

The person with less mass moved how to search property records because it takes less energy to move them. The other part of the demo is that the more massive person still moved This is explained by Newtons 3rd law which how to convert inches to decimals "To every action there is an equal and opposite reaction" or you could say You could explain the idea that every time objects move each other BOTH have the same force being pushed on them.

More massive objects don't MOVE as much but they still have the same energy exerted on them. This is also a good explanation for why we add water to the bottle. The water being pushed out from the bottle botttle more mass than just air so it pushes against the bottle harder which forces the bottle up with more force. You can tie this into Newtons 2nd law as well if the kids are still engaged at this point. Show how to cut a bottle safely rockey a blade. I cut a bottle open about 4 inches up from the bottom than show how they can stack.

Its up to you if you how to protect an egg in a bottle rocket the kids to use blades. Kids will use a whole roll if left to it. I demonstrate how much tougher and more accurate it is to use 4" strips of tape placed lengthwise. I find a scroll saw works great on cardboard and coroplast. Hot glue works well but i find that it is used WAY too much and kids burn themselves.

I find tape works well. The fins can also be taped on with care. Remind the kids about a couple of things They forget that the egg has to go in and out easily. I cut a hatch in the top bottle. Usually one team will forget this. Tools and Materials -Same as last class Today i like rockrt start with another how to keep area rug from moving on carpet of theory.

I verbally test the class to make uow they remember Newtons 1and 2 Laws than i introduce the 1st law, which goes like this Once things start moving they tend to keep moving until something happens to change how it is moving" I ask What would happen to the student with less mass if NOTHING was slowing them down. The students usually know that the kid would keep moving We talk a bit about why the student stops Now I ask them if both the small kid and myself started moving at the same speed who would go farther.

They know intuitively that I would This is where the "M" in the 1st law comes in. Show them simple examples on the board. So how does this relate to the rockets? What are the immediate effects of drinking alcohol explain that ro slightly heavier rocket will go further. A WAY heavier rocket will not move at all of course.

A ziplock of sand works really well. You can tell the kids this rocekt they come up with great stuff on their own One team used peanut butter which is heavy and also worked well as a protectant for the egg I've included a series of shots that i use to demonstrate the process to the kids The steps show how you can add rkcket bottles together with just a bit of duct tape. You can also use the duct tape to attach some fins. Notice also that i added water to the top non-booster bottle I have kids work out plans for parachutes sometimes.

They are pretty exciting for kids and sometimes work but need to be carefully planned. Most kids get a plastic bag, tape it to the nose and hope it will work. It won't.

Step 1: Day 1. the Introduction

Jun 07,  · In my science class, we were assigned to create a bottle rocket that would protect an egg after being launched and then "falling back down to Earth.". Egg Rocket Challenge! McCall STEM Festival The Challenge: construct a capsule to protect an egg from damage during a head-on collision between a pop bottle rocket carrying the capsule and a brick wall with impact speeds exceeding 75 kph. Rules: 1) Two or three people per egg rocket team. Jan 22,  · 4. Egg Protection Plan (EPP) Our rocket prevents the egg from breaking by giving it a softer impact. It is stuffed tightly into the roll of toilet paper, so it wouldn’t be able to move around and hit something forcefully, causing it to break. Instead of impacting against the hard walls of the funnel as the egg lands, it goes against the soft, less forceful toilet paper.

Many of the questions surround optimal flight and such could have answers deduced from how our own rocket did along with others we saw. We could compare the results of the different rockets and their builds. For example, thought the launch I discovered the best egg protection for us was a toilet paper roll. Also, a narrower rocket will have a quicker descent. We used an organic egg thanks to the fact it has a harder shell.

We cut apart the soda liter bottles, as instructed, and duct taped them back together to use for the body of the rocket. The cardboard was cut to serve as the fins of the rocket and hot glued on. The cotton balls surrounded the base of the fins, and also aided in protecting the egg. The egg we used was a raw, organic chicken egg, because the shell is more durable than that of a normal, white chicken egg.

The rocket was designed to have a good flight. We chose the angles best for take-off along with a good amount of water for water pressure. The pumper exert his energy into pumping the water, and the water pressure works off of the launcher, blasting our rocket off.

The process of our launch is also similar to the diagram Mr. Long gave us in class. Our rocket prevents the egg from breaking by giving it a softer impact. Instead of impacting against the hard walls of the funnel as the egg lands, it goes against the soft, less forceful toilet paper. Our rocket traveled 52 M. Our egg did not break, on both the practice run and the real thing!

It was launched at a 45 degree angle. We used ml of water. We looked up online, and many said 45 degrees was the ideal angle for rocket launch. The only thing that went wrong when our rocket landed was that the funnel broke — it was made of cheap plastic, and broke on both the practice and real run. We had to buy a new funnel from the 99 Cent Store in-between! It took the brunt force of the impact when the rocket landed, but the egg was safe and that was all that mattered.

Through the experience, I learned a lot about energy and force. I learned how much of each quantity should be used for the optimal performance of your rocket, and about how forces work off of each other. I feel very accomplished, knowing Ashley and I had a successful rocket and a successful landing for our egg! It was a fun, interesting experience that taught me a lot about our current unit in class.

How hard does the egg have to hit the ground to break? Is it better to have bigger fins or smaller fins on your rocket? Does it matter how far up on the rocket the fins are placed? Is it better to have a narrower rocket? How much water pressure should you have before the rocket takes off? Is it better to have a wider launch angle?

What factors are required for the rocket to hit the boat? What energy does the rocket use in take-off? Does the mass of the rocket effect take-off? Are fins or a tail on your rocket better? Would it be different if you used a liquid besides water?

Which is rougher on the egg, the landing or the take-off? Does the angle of the nose of the rocket effect flight? Making of Our Rocket We made our rocket using the following materials: 1 roll of toilet paper 1 bag of cotton balls 2 empty soda liter bottles 1 funnel Though in our practice launch, the initial one broke, and we bought a new one for the repair.

Our completed rocket right before the final launch! Physics of Our Rocket The rocket was designed to have a good flight. This is our rocket at the launch! Results Our rocket traveled 52 M.
