Welcome to my very own blog for learning. I look forward to sharing my learning with teachers, my school, my family and friends anywhere.

How the Earth was made

YouTube clip on how the Earth was made

• Our solar system is 4 and a half billion years old and the sun was surrounded by a cloud of dust and gas and the minerals began to clump together

• The minerals began to clump together

Link to Page

• They were held together by static electricity
• Minerals stick together to make rocks then rocks stick together to make boulders then the boulders stick together to make meteorites or planets and they were held together by static electricity

• After 30 million years Earth was made

Link to Page

• As the Earth got bigger it pulled more rocks and minerals into it

Link to Page

• Then the earth melted and all the metals sank and all the rocks floated

Link to Page

• The outside cooled and formed the crust

Link to Page

• The Moon formed when another planet collided into Earth

Link to Page

• all the rocks blown into space collected together to make the moon

• Every rock from space brought a drop of water and since earth started all the rocks that hit earth brought a tiny drop and with more than 5 million rocks that had drops of water in it our oceans were made

• Meteorites carried Amino acid witch were attracted to each other then they came together to make protein and amino acid replicated themselves aka copying themselves. They turned into DNA and then made bacteria. Witch then made life

• The bacteria breathed of a gas oxygen. Every bit of bacteria made a tiny bit of oxygen

Hands on fire

Aim: I want to safely set my hands on fire.

Equipment: Safety glasses, box, In the box water, hoes, Detergent (liquid soup), lighter

Method
1. Be safe Safety glasses Roll your sleeves up
2. Wet hands wrist and arms up to your elbows
3. Get a scope of bubbles
4. Move away from the box
5. Hold the bubbles at eye level as far away from body as you can
6. To put out the fire SLOWLY

Results
I didn't get a go put people looked really nervous when it was lit it looked like it went 1 metre high!

Walking in Straight lines

Aim: i want to try and walk in a straight line while i have my senses gone


Hypothesis: I predict that i will go the complete opisite question and wont walk in a straight line.


Equipment:

1. blindfold to stop us seeing

2. Cotton wool in our ears and noses to stop us smelling and hearing

3. Bucket to stop the wind

Method:
Im going to try and walk 200 metres.

First of all put that cotton up your nose

Next put some cottin in your ears

Now put your blindfold on and then put a bucket on

Results
Well i didint get a go but my budy XD she was heading to the tuck shop here are some photos

 Her at the end

Thinking there are trees everywhere

Food! her heading to the tuck shop

Burning magnesium

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





Hypothesis:
I think that is might just melt and maybe turn into liquid or stay together but burnt up



Equipment:
Heat mat, Bunsen Burner. Siccer tongs, Magnesium, Lighter and safety goggles




Method:

1. Get equipment
2. Put on safety goggles
3. Put down your heat mat
4. Connect your Bunsen burner to the gas tap
5. Close the air hole
6. Turn on the lighter
7. Turn on the gas
8. Open the air hole
9. Hold the magnesium in the scissor tongs
10. Put the magnesium into the blue flame
11. Observe what happens

Results:

When i burned solid shiny gray magnesium in the blue Bunsen burner it formed a bright white light and lasted for around 6 seconds then it went out. Some white powder was left over.        

Discussion
Why did the magnesium glow brightly?

When magnesium burns, it is actually reacting with oxygen in the air and not with fire. Fire is what we call the heat and light produced when things burn. Magnesium reacts with oxygen to make a compound called magnesium oxide. The bright light results because this reaction produces a lot of heat.

scienceline.ucsb.edu/getkey.php?key=2234

When magnesium is in its metal form it will burn very easily in air. However, in order to start the reaction (the burning) the magnesium metal needs a source of energy. The flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. An exothermic reaction is a term that describes a chemical reaction in which there is a net release of energy (heat).

Conclusion:
My hypothesis was that it would just melt or turn into liquid but it ended up turning into a bright white light


Evalouation
Other experiments related to this i could do are

• Did it make another chemicals
• Why was it a white light
• How hot did the magnesium get
• Do all metals glow brightly
• What would happen if we used a chunk of magnesium
• What would happen if we used powered magnesium

How to write a science report

Aim:
This is i want to find out


Hypothesis:
This is a educated guees



Equipment:
This is a list of the materials i need



Method:
These are step by step instructions

Variables
These are factors that can change the results


Results:
These are my observations
I need to do my results in a table

Anallysis
This is where you need to preform any calculations
I need to do a graph

Descusion:
This is where i explain the results and i answer the question why



Conclusion:
This is where i say if my hypothesis was correct



Evaulation:
This is your reflection on the investigation
