⚗⚛Testing for Simple Sugars⚛⚗

My Partner and I had made a solution that amazed my partner was the photographer and I was the person who did everything else. To find out more read down below.😃👍👇



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

  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 color to a yellow color to an orange/red color.

Conclusion

Our experiment was a success the color changed, and it didn't boil either but that was a good thing. It started with a nice light blue color then changed to a rainbowish color at the bottom after it went  to green than orange/red. 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. Also referred to as simple carbohydrates, these sugars are found naturally in a variety of foods that we consume daily.
. we put glucose powder (dextrose)  in first then we put Benedict's solution with a bit of water.

Science equipment

Equipment in Science


Today in science we had a new challenge and our challenge was basically like a quiz. We had to match equipment to it's name and use. It was pretty fun and you can have look too. Make sure to give me feedback on what I should improve.

A paperclip floating?

Today for science I had experimented on how to make a paper clip to float on water on our first try it was a success I was so fascinated on how it floated. so I made another one float and it was a success again.

Here is how it happened:


You will need

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

What to do

Fill the beaker with water
Try to make the paper clip float…not much luck, huh?
Tear a piece of tissue paper about half the size of a CARR card
GENTLY drop the tissue flat onto the surface of the water
GENTLY place a dry paper clip flat onto the tissue (try not to touch the water or the tissue)
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!

How does it work?

How is this possible? With a little thing we scientists call SURFACE TENSION. Basically, it means that there is a sort of skin on the surface of the water where the water molecules hold on tight together. If the conditions are right, they can hold tight enough to support your paper clip. The paperclip is not truly floating, it is being held up by the surface tension. Many insects, such as water striders, use this “skin” to walk across the surface of a stream.
MAKE IT AN EXPERIMENT


When you put the tissue under the paper clip it creates a thin skin called surface tension all the water molecules hold on tightly and is they hold tight enough it will be able to hold up your paper clip that allows it to look like it's floating. some tiny insect can walk across the water because of the thin skin on the water.

How to attract more people.
How to get people to read/notice your blog.

Answer:
You can bug your real friends and link your blog to other blogs but there is much more that I found on this site that has my answer.

Lava Lamp Disaster

In science, we had created a lava lamp .
And here is ingredients and the method.

Blobs in a Bottle         
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 coloring
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 coloring 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.
Big questions:
  1. Does the temperature of the water affect the reaction?
  2. Does the effect still work if the cap is put on the bottle?
  3. Does the size of the tablet pieces affect the number of blobs created?
  4. What is an oil spill and how do they happen?
  5. How do ice and water interact during an oil spill?
  6. How does oil affect marine life during an oil spill?
Scientific Explanation (How it works):

To begin, the oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules. When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water         
Oil is lighter than water so it stays on top of the water. the quick-eze go through the oil into the water and start to dissolve. When the dissolve they send bubbles up through the oil.
