Materials:

1.   4 Test tube
2.   Banana
3.   Bread
4.   Paper
5.   Styrofoam 
6.   Test tube rack
7.     Water 

Steps:

1.   Take the test tubes 
2.   Put the Styrofoam , paper , bread and banana into the test tubes
3. Put the test tubes with the ingredients in the test tube rack

Findings:

TODAY	Colour	Change	Observations
Banana	Yellow/brown		in the middle
Paper	Brown		The same length as the test tube
Styrofoam cup	White		half way
Bread	Beige		half way

• The banana is in the middle of the tube it is also white with brown. 
•   The paper is brown and it is the same length as the test tube.
•   The Styrofoam is white and it is half length of the test tube.
• The bread is beige and it is also half length of the test tube.

3 weeks	Colour	Change	Observations
Banana	Brown, green and black	rotten	still in the middle
Paper	Brown	same	got a bit smaller
Styrophone cup	White	same	half way
Bread	Green and beige	rotten	half way

How do we work in this laboratory?

1. Beginning and End of class: Lining up, Entry, Seating, 
2. 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.
• Conical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heat proof.
• Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.
• Test tube tongs - These are used to hold a hot test tube after an experiment.
• Spatula - This is for holding very small amounts of chemical powders.
• Funnel - used to channel liquids into a smaller container.
• Measuring Cylinder - This is used to measure liquids for experiments. The liquids will be poured into a beaker or test tube once measured out.

About Art Hurumanu

Art Hurumanu -
On Thursday me and my group did our characters, We all did our phoenix except I didn't get to finish mine because I was a away last Thursday. Qyn had a blue phoenix with black outlines on it, Davids character had yellow with a mixture of orange and Kelesi's character was plain black. Our back drop is a grey building and beside it was a volcano and some hot lava dripping out of it there was also some clouds at the back, we also put mountains behind the clouds, there was also a bright blue sky in the background.

Here are some of the pictures of our characters and back drops :

How To Self Manage.

What I did to show Self managing

I showed self managing by being organised and having the right stuff needed for my learning, by being focused on my work instead of chatting with other people and by working my personal best.

Being a self manager means your somewhere at the right time, have the correct gear needed, focusing on your work and by being learning ready.

I could be a better self manger by focusing on my work at all times instead of chatting, having the correct gear, sitting somewhere you know your gonna get work done and by doing your personal best at all times.

My goal is to do my personal best, have all the gear needed at every time and ignore people that try to distract me from my learning.
