Thanks Grace, I agree with you about putting more thought into your Science project you are an intelligent young woman and this was an opportunity to really extend yourself. On the other hand you have gone through the process of the project and structured your Science Fair well with easy to follow results and graphs. It is good that you have included the 'Science' behind why the cup with no added cold liquids cooled the slowest. Remember to include a bibliography when researching.
 * Teacher Comment:**
 * Student Comment: My science fair project was average it wasn't a poor effort or amazing it was just average. The topic was last minute change and to be honest I could of put more thought in to the topic. Writing the science behind it was challenging but at the end it was easy doing the research.**

**Introduction:**

This topic has been chosen to answer a basic question “Imagine you are making a hot drink. You are just about to add some milk when you realize that your neighbor is knocking on your door, should you add the milk now or wait until you have finished talking to your neighbor?

**Aim:**

My aim is to find out which cup of hot water stays hot the longest because its getting closer to winter and is starting to get cold.

**Hypothesis:**

My Hypothesis is that the cup with out any added ingredients will stay hottest the longest because the substances that have been added to the other cups are all cold sources.

**What you'll need:**
 * 4 cups that are exactly the same
 * Hot water
 * Cold water
 * Cold milk
 * A thermometer
 * Spoons

**Method:**

*The temperatures were taken every 30 seconds.*
 * 1) Boil the jug/kettle.
 * 2) Pour boiling water into cup and fill half way.
 * 3) Check that all of the cups are at the same temperature. Leave the thermometer in one of the cups.
 * 4) Add 1 tablespoon of cold milk to the first cup.
 * 5) Add 1 tablespoon of refrigerated water to the second cup.
 * 6) Add 3 tablespoons of cold milk to the third cup. Leave the last cup with nothing in it apart from the half of boiling water.
 * 7) Check the temperature of each cup every minute with the thermometer. Which cup of water stays hot for the longest.



**Discussion of Results:**

The results show that the cup with 1 tablespoon of water stayed the hottest for the longest at the end, but not for all through the experiment. I think that the cup of only just the boiling water in it and with out any added ingredients, being the hottest at the end, because there were no other added cold substances to make the temperature drop.

**Conclusion:**

I achieved my aim/goal to find out which kind of drink stayed the hottest for the longest. My Hypothesis was correct, the cup with out the added ingredients stayed the hottest for the longest. I think I should have put more thought into my science fair topic and chose one with a lot more research and work involved. Instead of just adding only milk and water I would actually experiment on cups of tea, coffee and Hot chocolate etc.
