Testing for Simple Sugars (Benedict's Test)

Today at science we have been testing for simple sugar ( benedicts Test). We worked as pairs and first, we took out a bunsen burner and set it up on fire, after that we took photos.

Next, we took out a test tube and added sugar. we added benedict solution, after that, we swirled the mixture in the test tube and over the flame, blue flame. I gave it to my pair and he dropped it on the floor, it was disappointing what happened 

Hope you like it and have a great day :)

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

1. Place about 2mL of the food sample into a test tube and then add 5 drops of Benedict's solution and 5ml of water
2. 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 yellow colour to an orange/red colour.

Conclusion

The chemical’s, sugar and benedict’s solution turned from blue colour to light orange colour as we mixed it over the blue flame.

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

HATW-Hover All The Way

Hello guys, since this week and maybe last week too we have been working on making our own advertisement. Advertisements are like ads that come in newspapers, iPads, iPhones and other devices and articles. We enjoyed it and there was a bit of a problem with my buddy but I can't tell you that. Anyways we chose to do a newspaper advertisement. I finished it and I am happy with what I have done. Hope you like it and have a great day😁👍.

Respecting Places/Property

Since this term we have been doing philosophy about respect things, there are four things to respect in HHS. Respecting people, places, property, and beliefs. We had to choose one and my teammate chose places. After that we made a slideshow about how to respect these places, we got mixed up with property and places so we had to put them together. We finished it but haven't done much in it because we had no idea what to put in it so we are happy what we have done. Hope you like it and have a great day😄👍.

Making a paperclip float

Today at science we have been making a paperclip float, we tried and tried and in our third we made it float. Its amazing and how we made it float, we will tell you soon after my short introduction. Okay so we worked for a little time on this experiment, well not much of an experiment. We enjoyed it and you could try it at home. Here is the instructions on how to do it.

• What you need

1. Clean dry paper clips
2. Tissue paper
3. A bowl of water
4. Pencil with eraser

• What you need to do

1. Fill the bowl with water
2. Try to make the paper clip float…not much luck, huh?
3. Tear a piece of tissue paper about half the size of a dollar bill
4. GENTLY drop the tissue flat onto the surface of the water
5. GENTLY place a dry paper clip flat onto the tissue (try not to touch the water or the tissue)
6. Use the eraser end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. With some luck, the tissue will sink and leave the paper clip floating!

Wee also have some of our experiment on floating a paper clip and a sunken paperclip

How it works is that if you drop the paperclip in the water it will sunk. But if you place a half a tissue so like half of a CARR card. Put the tissue in the water slowly onto the waters surface, also slowly put the paperclip onto the tissue. Wait a while, after some seconds use the end of the pencil to make the tissue sunk to the bottom. Don't touch the paper clip and sink the tissue slowly. Once it is about to sink, your paper might float depends on how you did it.

Good luck and have a great weekend😄👍.

Valedictorian Anonymous

A unknown person anonymously posted kind words about Classmates o Instagram for nearly a year, this person is sure kind about his posts. A high school valedictorian recently revealed that a young boy has been posting these comments to his own classmates. No one never knew until the school revealed it was a young boy. His name is Konner Sauve told some of his classmates that he was secretly posting comments for nearly an entire year on his secret account. Sauve shared over 650 photos of students at East Valley High School in Yakima, Washington which is amazing.

Also forgot to say in the first place Valedictorian means like you have the best grade in school and your the head leadership, I'm sure that's what it means. The messages he sent to his classmates made them pleased and blessed about it. But one day he revealed himself to the whole school, people were shocked. He was awarded in front of the whole school also his parents were there, He told them a speech and they were proud for him.

Blobs in a Bottle

Today at science we have been making blobs in a bottle, the other name is lava lamp. We followed the instructions on how to make it so once we were finished, we tried taking a photo but there wasn't enough i pads, also another reason is that one of our team mates ruined it and I am disappointed but its OK for me. Anyways we have the instructions and you could try making it at home. I have a few photos of it and I think we can succeed better that this. Hope you enjoy this Friday and have a great weekend.

Resources:

• A clean 1 litre clear soft drink bottle

• 3/4 cup of water                   

• Vegetable oil

• Antacid tablets (such as Quick-Eze or Mylanta)

• Food colouring

Procedure:

1. Pour the water into the bottle.
2. Use a measuring cup to slowly pour the vegetable oil into the bottle until it’s almost full. You may have to wait a few minutes for the oil and water to separate.
3. Add 10 drops of food colouring to the bottle; the drops will pass through the oil and then mix with the water below.
4. Break an antacid tablet in half and drop it into the bottle. Watch it sink to the bottom and watch the lava start to flow.
5. To keep the effect going, just add another piece of antacid tablet.
