= __Title: Big Gum Bubble:__ =

= __Aim:__ we are aiming to test bubble gum that will have the biggest bubble out of 5 gum, hubba bubba strawberry and pink, juciy fruit and air wave. The reason why we chose this = = = = __hypothisis:__I tihink that the hubba bubba will blow the biggest bubble because it's the type of gum for blowing" bubbles and it's the soft bubble gum. = = = = __Method__ = = We are going to measure the bubbles by taking pictures of the bubble as it get blowin and then measure from the picture on the camera. = = We abandoned this experiment as we found it was too hard to measure the bubbles and there were too many variables. The size of the bubbles depended too much on Callum and his technique than on the bubble gum. = = = =Wrapping up Warm = = __Aim__: We are trying to find out which insulation is best for keeping a drink warm. = = __Hypothesis__:Callum thinks that the foil will keep the drink warmest because foil is used to keep hot food warm. = = media type="custom" key="11490976" = = = = = = __Method__: = = __Equipment__ = = Foil = = clay = = Newspaper = = Cardboard = = fabric = = Rubber bands = = 6 jars all the same size = = Thermometer = = __Steps__ = = 1. We will wrap each jar in a different material and use rubber bands to hold them in place.We will wrap the bottom and the sides so they are all the same. = = 2. We will have one jar without any covering and that will be the control = = 3. We will take the temperature of the room first. = = 4. We will pour warm water into each jar to the same level and then take the temperature. = = 5. We will take the temperature of each jar every 15 minutes and record it on a table. = = 6. We will put our data on a graph. =

__Conclusion__
We found that when we tested the water the clay was making the water colder then expected. That was because lots of moisture in the clay.As for the foil it kept the liquid warmest for longest.The paper was having a go at keeping the liquid warmest for longest but the next time we tested the paperwasgoing down with its heat so bacily means the paper gave up on keeping the liquid warmest for longest. :) this such a fun experement so you should watch the vide
