States of matter

For science, I have studied what the different states of matter are and how they are made.  I also had to take a quick look at what fire is.  Is fire a Solid, Liquid, Gas or Plasma.  I struggled with this.   Overall this was a great experience and I would love to do this again.  Here is my work:

Decomposition/Recycling - Hurumanu

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think that either the banana or the bread with water is going to rot the fastest.

Materials:

1. Bread  
2. Water  
3. Paper 
4. Banana  
5. Stylophone  
6. 4 test tubes  
7. Test tube rack  

Steps:

1. Collect materials  
2. Sort out the materials in the correct order 
3. Add in each of the 4 equipment in each separate 4 tubes 
4.  Get a sticky note from the teacher and write your names on it

Findings:

3 weeks	Colour	Change	Observations
Banana	Green	Rot	It turned into green rot
Paper	Brown	Nothing changed	Nothing changed, it still looks the same
Stylophone cup	White	Nothing changed	Nothing changed, it still looks the same
Bread	Light Brown	Mushy	It turned into this weird

Conclusion:

In conclusion, I would like to say that I have learnt a lot.  I have out how long it takes for stylophone to rot it takes thousands of years.  So that means that it takes the longest to break down.  Banana is also the easiest to rot out of the four it had already gone mouldy.  I'd like to finish off with I would like to do this again and bye.

Behaviour in a Laboratory - Hurumanu

Aim: To learn about the expected behaviour in a science laboratory.

  Follow the instructions given to you by the Teacher.
  You must not enter the laboratory without your teacher.
  Report all breakages to your teacher.
  You must never eat or drink in a laboratory.
  Shoes must be worn at all times.
  If you spill something you should tell your teacher immediately.
 You should wash your hands after every practical activity.
You should know what you are doing. If in doubt ask your teacher.
Never taste or sniff chemicals.
In your group, discuss how the following scenarios could be dangerous.
Not putting your bag under your desk.
Running around in the laboratory.
Not wearing shoes in a laboratory.
Shaking a test tube with your thumb over its mouth?
How do we work in this laboratory?
Beginning and End of class: Lining up, Entry, Seating,
Equipment tray: equipment list and details.
Test tube - This is used for experiments using liquids. They have a bung that can be placed in the top. Test tubes sit in a test tube rack.

Does it take science to make a marble work?

My Question: Does it take science to make a marble run work?

Introduction

Hello my name is Lasa, and I am going to explaining what a marble run works. I’ll be taking you into some “scientific things”. I wonder what makes a marble move down lets go it gravity.

How gravity works

The answer is easy but again “scientifically important”. The magic is Earth moving round the Sun is in a dynamic equilibrium. The speed of the Earth's movement creates a centrifugal force which balances the gravitational force between the Sun and the Earth. ... Because there is no force to stop it.  

Kinetic energy, accelerate, decelerate

The power of movement is due to kinetic energy. The marble is accelerated faster and faster as it is using kinetic energy. When the marble slows down that is called anti acceleration.

Conclusion

In conclusion it actually does take science to create this wonderful creation.
