This Friday in science we've done a science experiment called Benedict Test. It is fun because we have to light a Bunsen burner to make the sugar change colors. And here is some photo down below how the sugar change.
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 saccharine.
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 2 mL of the food sample into a test tube and then add 5 drops of Benedict's solution and 5 ml of water
Gently heat the test tube over a blue flame. DO NOT BOIL!
Results
A positive test for simple sugar results in Benedict's Solution changing from a blue color to a yellow color to an orange/red color.
Conclusion
When we put the food coloring in the test tube it was blue then when put it on the fire it started to get change color.
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

Give two examples of simple sugars and complex sugars in your daily food? Complex sugar is Pea and Bean, simple sugar is milk and dairy foods.
At what times of the day may you need simple sugars? Sport
Do you think that it would be wise to eat simple sugars before bed? Why/why not? No, because it will be hard to sleep with all those sugar.
Well done Lars, you've used some great photos in your post. Can you please try to improve your layout next time so that your words aren't lost off the side of the page? I'm glad that you enjoyed using the bunsen burner. Keep up the good blogging.

ReplyDeleteGood job Lars I am from Hornby Primary School here I'am commenting on your blog again. I like the way that you list all the equipment that you need and how to do that experiment. Maybe next time you could explain more about The Benedict. But always you have some good quality blog post keep it up Lars :).
