__What effects ice when it melts?__ __Science Investigation__

__Hypothosis__ The ice in the cupboard will not melt since it is in a compact area were it is away from the sun and the air is compressed into the cupboard. In the 20 minutes it will not melt fully. The one in the shade will melt faster than the one in the cupboard but it will not melt fully like the one in the cupboard. Also because it is also away from the sun. The one in the sun will probably melt between 10-15 minutes due to it being in the sun which causes it to melt faster.

__Equipment: items I will need to do my Experiment__ - 3 plates (preferably the same) - 3 ice cubes - 3 flavoured ice cubes (you may have to make them before you do the experiment)

__Method: How am I going to test my question?__ 1. Take out 3 plates. In each plate place one ice cube and a flavoured one. 2. Then place one plate in the sun, shade and in the cupboard. 3. Observe the plates. Check: How long it takes to melt? Which one melts faster, the ice cube of the flavoured one? Do you think putting the ice cube together effects how it melts?

Ice cube size - both of the ice cubes have to be of the same size so it will be a fair test. Same type of plate - the plate materiel may change your outcome. Things I could measure: <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Size of the ice cube - you can measure the left over ice cube to see which one melted the fastest. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Water melted - the water that melted from the ice. || <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">I will change: <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Temperature - each plate will be in separate places which may effect the temperature. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">I will measure: <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Size ice cube - the size is very important to stay which one melted first. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">I will keep the same to keep this a fair test: <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Type of plate - this may change your results. ||

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; vertical-align: baseline;">__Result__ <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">The ice in the sun melted the fastest. The ice cube melted faster than the flavoured one due to the other ingredients added to it. The one in the cupboard melted a teaspoon amount because it was not under the sun and the temperature in the cupboard was normal. In the 20 minutes the one in the sun melted the fastest. The one in the cupboard melted the least and the one in the shade melted more than the one in the cupboard but less than the one in the sun.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; vertical-align: baseline;">__Conclusion__ <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; text-decoration: none; vertical-align: baseline;">In my hypothesis I said that the ice in the sun will melt the fastest. I was correct. The one in the cupboard and shade melted slowly. And didn’t fully melt in the 20 minutes. I think the flavoured ice melted slower because of the other ingrediants added.

Our main question was “Can you make water shrink or expand?”. In buzz groups we did experiments and did a science investigation. This is my Groups investigation:
