Today at science we had to setup a buns burner and we had to grab a test tube and put a bit of sugar in it and then we had to turn the buns burner and we had to put a type of liquid in the test tube with the bits of sugar then we had to swirl the test tube around the fire and remember always to wear safety glasses safety first and after it should turn orange after you have burned the test tube. And don't have sugar after bed because when you do you will stay up and you won't even go to sleep.
Testing for Simple Sugars (Benedict's Test)
Aim
I want to find out how to test for simple sugars.
Simple sugars are carbohydrates that are quickly absorbed by the body to produce energy. They are also classified as “simple” because they contain only one or two units of sugar or saccharides. Also referred to as simple carbohydrates, these sugars are found naturally in a variety of foods that we consume daily.
Equipment
Safety glasses
Bunsen burner
Test tubes
Test tube tongs
Benedict's Solution
Food sample
Method
Place about 2mL of the food sample into a test tube and then add 5 drops of Benedict's solution and 5ml of water
Gently heat the test tube over a blue flame. DO NOT BOIL!
Results
A positive test for a simple sugar results in the Benedict's Solution changing from a blue colour to a yellow colour to an orange/red colour.
Conclusion
…..
Extra for experts
Two different types of sugar exist: simple and complex. Complex sugar takes longer for your body to break down and is healthier for your body. This type is found in natural carbohydrates such as whole grains and fruit. On the other hand, simple sugar is broken down by your body quickly and causes energy ups and downs. This type of sugar includes refined and processed sugar found in table sugar and added to many sweets. Consuming an excess of simple sugar comes with numerous health problems

You've done a good blurb at the top Tyler, but it doesn't say that we used dextrose (a type of glucose sugar) and that we were testing to see if it was a simple sugar. Try to remember to take photos for your next blog post.
ReplyDeleteThere is a lot of information there Tyler! Mrs Hastie is right - photos would really add to your plog posts - especially those around science. Remember to proofread too - it's important to help us read it properly when there is so much information. Good job!
