Famous Scientist:

Image result for marie curieMarie Curie: 

What are they famous for?

Marie Curie is famous for discovering radiation/radium and how it works and also what effects it has. Marie was also part inventor of X-rays along side German scientist Wilhelm Roentgen in 1885. Marie Curie was the the first woman to win a Noble Prize. Adding to her first win in physics, she later earned one in chemistry, making her the first person to claim Noble honors twice.
 

Basic Information:
Marie is a youngest out of 5 kids she has three older sisters and one older brother. Growing up her parents always wanted their girls to succeed and be as good as their older brother. Sadly when Marie was 15 her mother sadly passed away due to tuberculosis. Ever since that day Marie was been using her mothers death as a blessing and wanted to do her mother proud by doing her best in school and completing her dreams/goals. A few years later Marie was able to join a university that allowed girls, at the age of 17 moving away just to be able to attend a university was pretty scary for her. She had her doubts about it but once giving it her best ability she was accepted. The teachers that taught her were impressed of the skill and knowledge she had. After studying a but more she moved to Paris and was awarded to be professor for Alexandrovitch university. After a few years she meet her long life partner Pierre Curie. They both were scientist and were able to discover radium,radiation and the effects they have. After discovering radium Marie was able to help Wilhelm Rontgen with inventing X-rays.  


What effects did he have on science today?
Well if it wasn't for Marie,Pierre curie and Wilhelm Rontgen a lot of medical scientist/doctors wouldn't have been able to discover anything like broken bones and fluid that may be around bones. Its not like they would have no way to find broken bones it would just be hard for them to see whats actually wrong like if it is dislocated or just broken or even just sprained.

Planets

Planets:


In science we have been learning about the 8 planets and what they are made out of. We have been asked to make a blog post of the planets in order from smallest to biggest and state one fact about each planet. 


Mercury-  Mercury is the closest planet to the sun which makes it the hottest planet out of the solar system.

Mars- Mars is named after the Roman God of War.

Venus-  It is sometimes referred as the sister of Earth.

Earth-  Earth is the only planet in the solar system to not be named after a Roman Deity

Neptune-  Because of the colour of Neptune it is referred to be name after the Roman God of Sea.

Uranus-  is the first planet to be found but the naked eye with a telescope. 

Saturn- Saturn is sometimes named after the (Jewel) of the solar system.

Jupiter-  Is named after the Roman King of God.

The Moon Landing:

The Moon Landing:

Today in science we are asked to research if humans really landed on the moon. 

I honestly think that humans really did land on the moon. 

The reason I think that its true is because after Neil Armstrong came back from the moon,he had moon dirt on his suit which he couldn't get off. So the scientist grabbed some of the dirt and tested back at the labs. 

Another reason is once they came back they said how bad the dirt smelt. 

Another reason is they practice non-stop for a while one of the ways they got ready for going on the moon was they walked sideways.

There is no way that in 1959 there was good technology to act this and fake this. I feel like human's actually landed on the moon this is just my opinion.

Acid Rain

Acid Rain:
Acid rain is a type of rain fall that is affected by the pollution from the atmosphere. Acid rain makes chemical weathering happen more quickly. Buildings and statues made from rocks are damaged as a result of the acid rain. Acid rain is another term for any form of precipitation with acid components. Such as Sulfuric or nitric acid
that falls from the sky.




Equipment: Universal Indicate (RED),Apple,Baby Pedal,Calcium Carbonate,Bromothynd (Blue),Water,Sodium,Acid.















                                                                                                                                                                                                                 Method: We first got the Petri Dish and the weight boat and all the equipment we needed. We then made the apple,Calcium Carbonate,Baby Pedal moist and sit them in the Petri Dish making them not touch each other. After that we put 3 drops of Universal Indicate and Bromothynd next to the apple and stuff without directly droping it on them. After that we added 1 scoop of sodium sulfide and a drip of water and mixed till dissolved. We them added 5 drops of Acid them quickly put the lid and. We sat their and watch the magic happen.





                                  









Results: The apple went hard and crusty the Flower also when hard. The universal Indicator went green to red. The Bromothynd went blue to green. and the Calcium Carbonate went a bit crusty.

How did you set up your Microscope and Microscope slides?

We started off getting the Microscope out and on to the table. We then got the light bulb box plugged in and faced it at an angle to make the mirror and the light make a reflection. After that we then got the microscope slides set up but putting Stain onto the specimen in the middle of the clean side then we broke a piece off of the leaf to make it turn white. After putting the leaf on the stain drops we put this light glass thing and went to the microscope to look down the lens.

What did you observe down the Microscope?

When looking down the lens we will looking at plant cells which looked something like this but brown because of the stain we used.







What are the key similarity and differences between plant and animal cells?

Plant and animal cells are nearly almost the same in different ways. For example, animal cells do not have a cell walls but plant cells do. Animal cells are mostly round and circle in shape while plant cells are rectangular shape. 

What was something that you discovered?
The one important thing I learnt/discovered was how to set up a Microscope and how to identify most cells.

What are some other microscopes that are made?
  • Simple Microscope. Simple microscope is the one which only uses a lens. 
  • Compound Microscope. 
  • Stereo Microscope. 
  • Optical Coherence Microscope. .
  • Fluorescence Microscope.
  • Scanning Probe Microscope. 
  • Point Projection Microscopes. 
  • Acoustic Microscopes.

Biuret Test

Biuret Test: 

Aim: To test if a sample of food contains protein.

Method: 1. Place about 2 ML of the sample into a test tube and add 5 drops of sodium hydroxide. 2. Add 5 drops of copper sulfate. 3. Shake the test tube gently from side to side. 

Result: If the solution remains blue, then no protein is present. if the solution changes to a purple colour then protein is present. 

Conclusion: Since most of us didn't get it to work it just stayed blue. But if we were able to get it working it was meant to change colour to purple.

Test for simple and complex sugars.

Simple Sugars: 

Aim: To test a sample of food to determine whether it contains simple sugars. 

Equipment: Bunsen Burner, test tube tongs. Benedict solution, a sample of food. 

Method: Place about 2ml of the sample into a test tube and then add 5 drops of Benedict solution.  

Results: That the apple turns orange after time of heating. 

Discussion: So what that means is there was simple sugars in the apple.
Conclusion: The banedict started off as blue after time heating the apple it made it orange.





Complex sugars:

Aim: To test a sample of food contains complex sugars.

Equipment: Test tube, food sample, iodine solution. 

Method: Place about 2ml of the sample in a test tube. Add up to 3-4 drops and iodine and mix.

Result: If a complex sugars are present the iodine will change from brown to blue or black colour. If there are no complex sugars the colors wont change. 

Discussion: So what that mean is that there are complex sugars in the bread which made the bread change colors.

Conclusion: The bread started off brown after time  the iodine made it black or clue.
