Water Rockets

1. Water Rockets By Ally Beagley 7F

2. Water Rocket Design Cone Made out of paper because it’s light weight and durable. Bottle Plastic Coke bottle because it is important to recycle. Fins Reusing a broken plastic ruler and cut up folio to help direct it the right way.

3. How Does The Design Effect The Flight Pattern? • The Light Weight Materials are so it takes less force to push it so it will travel further. • The front of the bottle has a cone on the front so it will cut through the air like a ship cuts through the water. • We have glued on the ruler and cut up folio so it doesn’t spin when it’s in the air. • We have drawn on the cone a smiley face because it looks cool!

4. It’s First Ever Launch This was its first ever launch it was at this angle and looked like this. We filled it up ¼ of the way and it came 2nd-3rd and I thought it went pretty well.

5. Modification From this.. To this! We took the ruler off the bottom of the rocket and glued it on the top and attached straws on the sides.

6. ModificationPerformance Once we had launched our rocket the second time once it had been modified, it didn’t go as far as it did the first time.

7. The Launch Angle • The angle that we had it at is important because if it was any higher this would happen: ! 20*

8. Newton’s 1st Law Of Motion • If an object is at rest (still), it will remain at rest unless it is acted upon by a force. If an object is in motion (moving), it will remain in motion, along a straight line and a constant speed, unless acted upon by a force. • At the start our rocket is still, until the air goes into the rocket and causes the Water to come shooting out of the bottom and the rocket goes flying into the air. Then when gravity kicks in the rocket finally comes to a stop on the ground.

9. Newton’s 2nd Law Of Motion • Newton’s second law of motion describes how the mass of an object effects the way that it moves when a force is applied to it. • If our rocket has too much water in it, the mass will be too heavy which will cause the rocket not to go far. But if we put not too much water in it and use light-weight materials that it would go further.

10. Newton’s 3rd Law Of Motion • Newton's 3rd law of motion looks at how forces affect things in our everyday lives. Newtons 3rd law of motion is:“For every action there is and opposite and equal reaction.”(force) • The opposite reaction is that when the water rocket goes up, it will always come down.
