Science Experiment (Simple Sugars)


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
Gluecose Powder (Dextrose)

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 simple sugar results in Benedict's Solution changing from a blue colour to a green to yellow colour and lastly an orange/red color.

Conclusion
When heat reaches the Benedict solution, it changes color to blue and to red/orange. Also when the heat is too hot, it can boil and spill everywhere.





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.

      Simple Sugars

Candy/Lollies
Fruit

      Complex Sugars

Bread
Vegetables

At what times of the day may you need simple sugars?

Lunch
Parties
Events


Do you think that it would be wise to eat simple sugars before bed? Why/why not?

I think you should not eat simple sugars before bed because, if eat simple sugars before bed you might get a lot of energy. That also means that you might not sleep that early because you ate simple sugar.

What respecting beliefs and religion looks like at HHS?

This term in philosophy we've been learning about respecting people, places, property and lastly beliefs. We had to partner up, and I chose Axle to be partners with me. We also chose, respecting beliefs. So what does respecting beliefs mean? It is like respecting people but their cultures. We have made a DLO about respecting beliefs. It is about Buddhism, Christianity, and Hindu. It is really important to respect each other. It can prevent fighting violence etc.

But anyways I hope you enjoy and I hope you learned something

Floating Paperclips!

This week we have been doing some experiments in science. Our experiment today was about making a paperclip float, but before we did that we needed a few materials to do this. Here are the materials we needed.

Materials:
Clean dry paper clips
Tissue paper
A bowl of water/or beaker if you have one
Pencil


How to do the science experiment:
After you have all the materials you need, you have to get a bowl of water.
Put in the tissue paper (don't make it too big.)
Next put the paper clip on top of the tissue.
Lastly get your pencil and press down the tissue and watch your paperclip float!

How does it float? There is a word called surface tension. It means that there is like a sort of skin on the surface of the water. It doesn't really float it is actually being held by the surface tension.
I hope you enjoy and I hope you learned something. I also have a question, what items do you will float?

How do we make a quality blog comment?

Some of you might already know how to make an excellent comment. But maybe some of you don't, to start off. You should write a positive start. For example, "Hi Carl, I really liked your work about how mummification works." It tells the blogger that you have liked his work, you should also put a thoughtful part. Here is another example. "I also have wondered what it is like to be a mummy, will it be hard?" It tells the blogger that you showed that you have actually read his work.

Helpful, the helpful part of the comment is pretty important. This is an example, "I think that there is one small mistake, I think that you have spelled something wrong with your work." The blogger will then remember to proofread his work before posting. The blogger might even improve..

But anyways I hope you enjoy and I hope you learned something, Bye!
