**Teacher Comment: Very well spoken Samuel. You have come up with a great science fair project that was relevant to you. I can tell you put alot of effort into this and it has paid off so well done. Next time it would be great to try and design your science fair with an eye catching title and display - this will draw the judges attention to your science board and really stand out from the. Other than that you have done a fantastic job well done.**

**Student Comment:** **:** Rats food choice Key:Rat 1=Molly Rat 2=Charm

__Introduction:__ Almost everyone who has rats can’t be bothered to give their rats mouth watering dinners everyday for dinner, so I wanted to know if they actually enjoy their meals, by putting __Pea__, __Apple__,__Ham__ and __Rat food mix__ into different containers and seeing what one they go for and eat the most. I wanted to do this because it will be pretty annoying if you got food you don’t actually like.

__Aim:__My aim is to work out what food do rats prefer the most out of pea, apple, ham and rat food mix. I am going to do this by putting 4 containers full of different foods and see which one they go to and eat. I’m doing this for 4 days.

__Hypothesis:__I think that they will go for food 1 first then go to food 3, food 2 then to food 4 because usually every sort of omnivore goes for a meat first and because when I gave them their food before the experiment they traditionally leave the apple for last.

__Materials:__ 2 rats. 2 containers. meat, fruit, rats food mix, vegetables. laptop 1 piece of paper

__Different Foods__

Food 1: Meat. Food 2: Rats food mix. Food 3: Vegetable. Food 4: Fruit.

__Method:__

Step 1: Put 1 little piece of meat, 1 pea(vegetable) one of each rat food mix,1 little slice of apple(fruit) in 1 container. Repeat this for the second rat. Step 2: Give the other rat to someone else to look after. Step 3: Get the rat you are going to do first and put the rat beside the container. Step 4: Watch the rat and record the result on what they go to on the day you are doing it on. Step 5: Put which order they go on a peace of paper then update it on your laptop.

__Results:__

Day 1: Rat I= Went for Pea(Vegetable)First.Apple(Fruit)Second.Ham(Meat)Third and Rat mix Forth

Rat 2=Went for Pea (Vegetable)First.Ham(Meat)Second. Apple(Fruit)Third and Rat mix Forth

Day 2: Rat 1=Went for Rat food mix First.Apple(Fruit)Second.Pea(Vegetable)Third.Ham(Meat)Forth.

Rat 2=Went for Ham(Meat)First.Pea(Vegetable)Second.Rat food mix Third.Apple(Fruit)Forth.

Day 3: Rat 1=Went for Ham(Meat)First.Rat food mix Second.Apple(Fruit)Third.Pea(Vegetable)Forth

Rat 2=Went for Ham(Meat)First. Rat food mix Second.Pea(Vegetable)Third.Apple(Fruit)Forth.

Day 4: Rat 1=Went for Ham(Meat)First.Pea(Vegetable)Second.Apple(Fruit)Third.Rat food mix Forth

Rat 2=Went for Ham(Meat)First.Pea(Vegetable)Second.Rat food mix Third.Apple Forth

Day 5: Rat 1=Went for Ham(Meat)First.Pea(Vegetable)Second.Rat food mix Third.Apple Forth

Rat 2=Went for Ham(Meat)First. Rat food mix Second.Pea(Vegetable)Third.Apple(Fruit)Forth.

__Conclusion__: My hypothesis was wrong for the first two days but but for the other three days they both went for ham. It didn’t go as I expected because I usually give them food in the morning so I thought they would be hungry but they started climbing around the cage and everything but after a while they got tired and had the food. There were two things I could of done to change it.

1)I could of took the other rat out of the cage because it climbed around and distracted the other rat from eating the food.

2)Before doing the experiment I could put the food in the container because I forgot to do that and when I got the rat out It was climbing all over my shoulder and getting in my way.

Rats have extremely sensitive learned food-aversions. If a rat does taste a new food it may try only a small amount the first time. If the food makes the rat feel ill it will try to avoid it in the future. If it eats something that makes it fell nauseous it cannot vomit so it has to be careful what goes in its stomach...But it does have an alternative to vomiting called “Pica”.

Rats prefer to eat grain, livestock feed and meat. Rats have also known to soap leather furs, candy, milk, meat, vegetables, poultry, eggs, grain, seeds, fruit, nuts, snails and other rodents.

Statements: •Looks like ham wasn’t the most favorite but then rat 1 started digging into the ham.

•Pea was liked on the first day but on the third day it was gobbled up last.

•Rat food mix was loved on day two with eaten up first.

•Pea was liked on the first day but on the third day it was gobbled up last.

•Rat food mix was loved on day two with eaten up first.

Statements: •Ham was the most popular on day three,four and five by being swallowed first.

•Pea has had been eaten first,second,third and forth.

•Apple hasn’t been eaten at all first(I guess no one likes fruit)

===Aim:To find out and name what the 5 substance were. ===

===Method:First we put a 1/4 of a tsp of cornflour in then we put half a tsp in then we gave it a mix and smelt and figure what it was. For baking soda we put vinegar in. ===

E=Cream of Tartar

====Please Note:  ==== ====This table is different from the one outlined in the above Science Fair booklet. There will be__**no extensions**__ given, Class time will be given for writing up aim, hypothesis, instructions, explanations, diagrams, tables etc and putting displays together. Parents please support your child with carrying out their experiments as this will be the main element of their homework during Science Fair. ====
