  1. 1.to inprove my boat we are going to use a bigger sale so the boat can have more air yo float.
    2.to inprove our boat we are going to use one big bottle so our boat would bevmore lighter.
    3.to inprove our boat we are going to put plastic at the bottom of our boat because plastic can float.

  2. 1.To improve our boats , we are going to make the sail large because the sail will catch more wind therefore, it will make the boat travel faster and further .
    2.We are going to make the mast even more stable ,because when the wind blows the mast doesn’t fall in the water .
    3. We could make the boat more light so, the boat doesn’t drown. We are going to use only one bottle so it makes the boat light.

  3. Was it waterproof?Yes it was waterproof.
    Did any of your materials absorb any water?Yes the sponge/foam soaked in the water.
    Was it streamline?No it was not streamline.
    I will improve my ship with a sail a because we used a rubber band power one it did not succeed.😕It fell apart in the water😫 but it would of floated anyway with out the lollipop sticks.I will also improve it cutting✂️ the top off from my bottleto put of less waight on the boat.I will use cloth for my sail🏴 to make it more ship like.My old boat had lollipop sticks on the bottom and lollipop sticks sticking out the sides with sponge/foam

  4. we needed to improve our boat by making the sail bigger so it can catch more wind so it can travel from a to b.

    We needed to make the boat float so it can
    absorb through the water.

    We needed to improve the lollipop sticks because we didn’t need them on the
    bottom.

  5. Our boat floated and it did get to A to B. We are going to change the sail and make it bigger and we are going to take of the sticks and put it on the bottom of the boat to make it float because if we didn’t put on any sticks it might not float and might sink and we are going to add a balloon to our boat so it goes faster in the water and it did go fast in the water in our experiment the material that we used was waterproof it was a plastic bottle and we used a balloon ,masking tape,card,and lollyipop stick we chose a triangle shape for our boat beacause it is the fastest.We didn’t use a sponge beacause it absorbs the water in but the plastic didn’t absorb the water in it was waterproof.🌹

  6. we are going to make our sail larger so it will be able to catch wind.this will make the boat travel faster and further.
    Our result was that it travelled but went the wrong way.
    Our boat can go faster if we took the the lollipop stick of so it can be lighter.
    We investigated what materials were good for our design.
    We used a waterproof material so it doesn’t absorb water.
    We are going to put some triangle part on so it goes faster and cuts through the water.

  7. To improve our boat,we are going to change 3 things which are on the prototype. I think the best thing about the boat is the big bottle in the middle.

    1)We could not use rubber bands to connect the little boats to the big boat. We could use tape instead

    2)I think the sail should be bigger to catch more wind and the mast needs changing because it’s droopy and unstable. The tape also needs changing so the boat has resistance from the wind.

    3) I think the raft at the bottom of the boat should not be there because it doesn’t do anything or help in anyway.

  8. To improve my groups boat i am going to:
    1)I am going to improve my boat by making the sail bigger so it will catch more wind and then it will push the boat.
    2)I am going to get a new mast and replace it with old one so it stands up and the sail can catch wind.
    3)I will get another piece of card and cut out a triangle and put it at the front of my boat so it can cut through the water.

  9. We can improve our boat, with bigger sail and make the boat lighter and make it faster and further, make it float and make it move A to B
    1- we are going to make our sail larger so it will be able to catch more wind. This will make the boat travel faster and further.

  10. To improve our boats, ⛵️ we are going to change 3things on our prototype :

    1. we are going to make it stable and making it go faster to do that we are going to catch more wind .

    2. We are going to make our sail larger so it will be able to catch more wind .this will make the boat travel faster and further .

    3. We need it to be a bit more lighter and work as a team more.

  11. I am happy that are boat traveled to a to b but we cud improve the propeller because it flew of and make sure the propeller is fully under the water so the boat wud of when’t faster.

  12. I predicted my boat would be filled with water and then sink because their was a large gap in the middle.
    When we tested the boat unfortunately it sank.
    These were the negative traits,it could be better by the propeller because it wasn’t secured on and it wasn’t touching the water.
    The positive traits were only about the flag and how it secured on.
    We could improve it by better propellor and not cut a huge hole in the middle.

  13. I predicted that my boat would sink because the propeller was not under water.
    When we tested it the boat only made it halfway and the propellor fell of.
    These were the positive traits.It had balanced sides so it would not flop to the side.
    These are the negative traits.It started to sink.
    We could improve it by making sure the propellor is more stable.

  14. When we tested it my boat did not go as planned. I predicted my boat would absorb water because it had a hole so it wasn’t fast and If the water carried on getting into the boat it would have sank.

    These were the negative traits:the propeller did not work and the boat was to heavy
    We could improve it by making a better propellor, by making sure the blades are the same size and making the propeller go inside the water so it pushes my boat and helps my boat move faster and also a more stable boat by putting less wait on the boat.

    I will do this by making sure the propellers are the same and also make sure they are in the water pushing the boat.

  15. My boat was plastic so it was waterproof but it tilted to one side because I a bit at the top that was not secure and it started sinking plus the propeller was not in the water so it could not move.

  16. I predicted my boat would sink because it was cut open. When we tested it unfortunately it sank because water got inside it. These were negative traits it tipped over because it was heavy on one side.
    We can improve it by putting the proppeller under the water, and making sure the boat is closed on all sides so water can’t enter it.

  17. I predicted my boat would move at least quarter of the tub of water.When we tested it the boat did not move and tipped over because it had uneven weight.
    These were the negative traits it nearly sank at the end.We could improve it by building the propeller so it would go under the water.

  18. I predicted my boat would float and travel from A to B. However, the propellor fell off because it wasn’t secure, which meant my boat didn’t from A to B.

    To improve my boat I need to make a propellor that is more secure. I will also make sure my propellor goes underwater by makeing it face down.

  19. I predicted my boat would not float from A to B.
    When we tested it I found out that the boat did float from A to B and the propellor was falling of because it was not secure.
    There were positive traits such as the boat floated however the negative traits were that the propellor was falling of.
    We could improve it by securing the propellor and make sure it is in the water, so it moves the boat better.

  20. To improve our boat,we are going to change 3 things on our prototype:

    1)We are going to make our sail bigger so more wind catches it and it goes faster and further.We are going to use a different material.

    2)We are going to make it less heavier so our boat goes faster by taking foam of and some lollipop sticks.

    3) We are going to make it our boat smaller by cutting it into a different size

  21. 1. We are going to make our sail larger so it will be able to catch more wind. We could make it more faster beause it has a big saili

    2. We could make our boat more light.

    • 1. We are going to make our sail larger so it will be able to catch more wind. We could make it more faster beause it has a big sail
      2. We could make our boat more light because we could take off the hull.
      3. We could make our bottle curve because it will go more faster.

  22. The evaluation
    I predicted my boat would sail the fasted.
    When we tested it the boat it sailed
    These were the positive/negative traits the positive thing is that nothing fellof the negative thing is that the rise was to much and it made it slow.
    We could improve it by making the rise fair.

  23. The evaluation
    I predicted my boat would float and reach point B. I thought the wind would push the bottle and it would float. But when we tested it,the boat did float and reach point B,but not the way I wanted. These were the positive things:It floats,reaches point B and moves in a straight line. Now these are the negative things:It did not move fast enough. We could improve our boat by adding fans to the bottles so that the wind pushes through the bottles and the boat moves. Also we could do more decorations on our boat like a fire. We could also make it more pointy at the front.

  24. I predicted my boat would not float because it didn’t have a proper sail.When we tested it floated but the sail didn’t catch that much wind.We could improve by making a proper sail and use a pedal.Our boat float from A to B without catching any wind.To make it a fair test we did this by using the same amount of water,Using the same shape and the same size and we dropped it from the same distance.All of the pepole made their boat out of plastic bottles some of them used three (One big and two small) and some of them used one big plastic bottle,most of them had a sail and one of them had a balloon that made it go fast.All of the other ones needed wind to make it go fast.

  25. I predicted my boat will work because the wind might attract to the wind and the wind will push it. When we tested it the sail did not attract to the wind so it did not go . We could improve it by putting a ballon onto it to make it way faster then it was befor we tried it out . I also thought that the rice will make it work really well . When we tried our boat out , it just crept on crashing into the sides .

  26. My boat traveled from point A to B because we blew the sail which made it float.
    When I tested my boat it didn’t drown,it just carried on floating.
    We could improve it by not putting too much dried rice in it.
    Our investigation was a fair test because every body putted it in the tray at the same distance.

    By Haleema and Menahel.

  27. I predicted that my boat will not reach the end but it actually worked and went to the end without stopping or sinking.

    When we tested it it went really fast.

    We could improve our boat by giving it a point and a peddler.
