What I am doing in science



                    Benjamin Franklin


In 1752. It was on a dark afternoon in Philadelphia. Benjamin Franklin a 46 year-old man who decided to fly a kite. With some help from his son William. They attached his kite to a silk string, he tied an old iron key at the end. Then they tied a thin metal wire from the key and inserted the wire into a Leyden jar.
     ←
That is a container for storing an electrical charge ,Finally as the sky darkened and a thunderstorm approached,
He attached a long piece of silk ribbon to the key. Holding onto the kite by the silk ribbon, when the kite flew up into the air, He retreated into a barn so that he wouldn’t get wet. The thunder storm clouds passed over Franklin's kite.The negative charges in the cloud passed onto his kite down the wet silk string, to the key, and into the jar. Ben however, was unaffected by the negative charges because he was holding the dry silk ribbon, insulating him from the charges on the key. When he moved his free hand near the iron key,
He received a shock. Why? Because the negative charges in the key were so strongly attracted to the positive charges in his body, a spark jumped from the key to his hand.
or The electricity struck the string of the kite because of the key the electricity reacts to metal and stikes the key then the lighting runs down the line.

How the Earth was made

YouTube clip how the Earth was made


  • meteorites are older then rocks 
  • 4.5 million years ago the sun was surrounded with gas then the cloud cooled
  • minerals stick together like rocks
  • the Earth melted to a big ball of lava 

  • another planet banged into Earth and then the crust broke off and some rocks suck together and made the moon

Tie your hair up












That's better












Roll sleeves up













There we go











Sorry half of it I forgot to stop half the time

Burning Magnesium

Aim:
I want to find out what happens when I burn magnesium

Hypothesis:
I predict that when the magnesium is put on the fire it will get very hot.

Equipment:
Bunsen burger
magnesium
scissor tongs  
safety glasses

Method

1.Get your equipment
2.Light the Bunsen Burger
3.Hold the magnesium

Results

discussion:
Fire is what we call the heat and light produced when things burn.
I predicted that when the magnesium is put on the fire it will get very hot. I was incorrect it actually glowed bright white

Evaluation:
Other experiments related to this I could do are

*do different kinds of metal glow when it gets put on fire





Writing a scientific report

Aim:
This is what I want to find out

Hypothesis:
This is an educated guess.

Equipment:
This is a list of materials I need

Method:
These are step-by-step instructions

Results:
these are my observation  (What I can see,smell,feel,hear,taste)
I need to do my results in a table.
Also,I need to do a graph.

Discussion:
This is where I explain the results and I answer the question "Why?"

Conclusion:
This is where I say if my hypothesis was correct.

Evaluation:
This is a reflection on what went wrong and what I could have done better.
