Transcript of Which cereal absorbs the most milk?

Which cereal absorbs the most milk? The most important meal of the day is breakfast and there’s nothing worst than starting your day with soggy cereal for brekkie.

I conducted this fair test because I wanted to know which cereal absorbs the most milk and which remained the crunchiest for longest in milk. Why I chose to find out? -Temperature of the milk.
- Amount of cereal in each bowl.
- Sugar in the cereal
I will make sure the temperature of the milk in each bowl was the same and that the amount of cereal in each bowl was equal. The sugar in the cereal is beyond my control. Things that can affect this investigation Things we could measure/observe -The amount of milk
-The texture of the cereal
-Time
I will make sure that each bowl of cereal has the same amount of milk and that all bowls will have the milk poured and drained at the same time. Materials and equipment 400 ml of Milk (100ml per bowl)

40g of coco pops

40g of sultana bran

40g of weet bix

40g of corn flakes

Stop watch

Bowls

Sift

Measuring cup Materials Before conducting the fair test I predicted that the cereal that would absorb the least milk in a 5 minute time frame would be the Sultana bran because it looked very dry. I also predicted that the cereal that would absorb the most milk would be the weet bix. Procedure. 1. Pour 40g of each type of cereal in to four separate bowls.

2. Pour 100ml of full cream milk in each bowl but they must all be poured at the same time. Have someone ready with a stop watch.

3. Once milk is poured, observe the appearance of the texture of the cereal and the milk.
Take a photo after 1 minute , then another at 2 minutes and then 5 minutes.

4. When the stop watch has reached 5 minutes pour/ drain out milk using a sifter but make sure each bowl of cereal is being drained at the same time and but separate.

5. The milk must be drained in to a measuring cup.

6. Observe the amount of milk in the measuring cup and record it.
Once you have recorded the amount of milk left over from each bowl, calculate the difference by taking it away from 100ml (the amount of milk that you started with). Procedure. Coco pops-
Start: 100ml of milk
After 5 minutes: 70ml
Milk absorbed- 30ml
Sultana bran-
Start: 100ml of milk
After 5 minutes: 50ml
Milk absorbed- 50ml Results Corn flake
Start: 100ml
After 5 minutes: 50ml
Milk absorbed: 50ml

Weet bix
Start: 100ml
After 5minutes: None
Milk absorbed: 100ml Results My Prediction The reason why the coco pops absorbed the least milk; is because it contains the most sugar out of the four cereals. Cereals with a sugary coating such as coco pops, is more likely to absorb less milk because the milk has to break the coating first before it comes into contact with the cereal itself. (Delisle, 2012) Outcomes I was correct in my prediction that the weet bix would absorb the most milk in the 5 minute time frame but the cereal that absorbed the least was coco pops.

Hansen (2012) accentuated that cereals with more starch are more likely to absorb milk more milk therefore in this case, weet bix contained the most starch and thus absorbed the milk the quickest. Outcomes & Research The reason why the coco pops absorbed the least milk; is because it contains the most sugar out of the four cereals. Cereals with a sugary coating such as coco pops, is more likely to absorb less milk because the milk has to break the coating first before it comes into contact with the cereal itself. (Delisle, 2012) Outcomes As part of the syllabus students need to be able to devise fair tests, this fair test would be appropriate for the classroom because it is safe and the resources are accessible. Therefore this fair test can be modelled in the classroom to the students so that they understand the process of a fair test before they conduct their own. How it can be applied in the classroom? This fair test is suitable for stage 2 & 3 students. This same activity can be used in the classroom but the question can be changed.
Does cereal absorb hot or cold milk quicker?
