Testing for Simple Sugar

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.

Science equipment

In science, we have been doing science experiments but we have to know what is the equipment first. That's why we have to match the picture down below.

Respect

Hello everyone in philosophy we have been doing how to respect our school and other peoples property. Philosophy is fun because you can work with your friend. In our google slide, there will be a photo that one of my friends take a photo. Also, we will explain what respect in our school is.

How to make a paper clip float

This week in science we have been doing a science experiment. It's fun because we have to make the paper clip float.  Floating a paper clip is fun when you make it because. But before you make it you will need some material.

Material:
clean dry paper clips
tissue paper
a bowl of water
pencil with eraser

If you don't know how to do it just follow the step.

• Fill the bowl with water
• Tear a piece of tissue paper about half the size of a paperclip box.
• GENTLY drop the tissue flat onto the surface of the water by using a pencil.
• GENTLY place a dry paper clip flat onto the tissue (try not to touch the water or the tissue) poke the tissue (not the paper clip) until the tissue sinks. With some luck, the tissue will sink and leave the paper clip floating!

Hey guys after you made the experiment make sure you answer the question. (Only if you want)

How many paper clips can you float and also what's your more favorite part of the experiment?

After we did the experiment the paper clip start to float so that means it worked. I was so happy because I really want the experiment to work.

   The tissue in the beaker               The tissue has sunk                                 Watch the paper clip float

                                                                                                   

Kindness Ideas

What will you do if you see a person that needs help?

If you see a person that needed help make sure that you help them because if you do that it will also come back to you someday if you need help too. But you don't need to always do that because sometimes you don't have any money to help them. If you feel bad about them there is another way to help them you just need to think. Sometimes in our life, we can't always help people because we don't always talk to strangers.
