Hurumanu - Decomposing and Recycling

Hurumanu - Decomposing and Recycling

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

Hypothesis: I think that the banana and the bread well rot faster.

Materials:

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

Steps:

1.  Put test tubes in the rack 
2.   Take stale bread and put into the test tube 
3. Take cut up banana/s into the tube
4.   Cut up strips of Styrofoam and put one in tube
5.   Take cardboard strip an place in the tube 
6.   fill the tubes with water 
7.  wait and see results

Findings:

• TODAY	Colour	Change	Observations
  Banana	yellow-brown	slimy	-slimy
  Paper	dark brown	soaked	-
  Styrophone cup	white	none	-
  Bread	white	moist	went down turning into a squiggly fold smush

  
  
  •   banana is yellowish-brown slimy 
  •   paper is dark brown soaked 
  •   cup colour is the same and no change
  • bread is white moist went down turning into a squiggly fold smush

3 weeks	Colour	Change	Observations
Banana	brown and yellow	slimy	banana is yellowish-brown slimy
Paper	dark brown	No change	paper is dark brown soaked no change
Styrophone cup	white	No change	cup colour is the same and no change
Bread	green, white and brown	mouldy and rotten	bread is green and rotten

•   banana is yellowish-brown slimy 
•   paper is dark brown soaked no change
•   cup colour is the same and no change
• bread is green and rotten 

5 weeks	Colour	Change	Observations
Banana	brown and yellow	slimy	banana is yellowish-brown slimy
Paper	back brown	nothing	paper is dark brown soaked no change
Styrophone cup	white	nothing	cup colour is the same and no change
Bread	green, white and brown	mouldy and rotten	bread is green and rotten

  

• banana is yellowish-brown slimy 
•   paper is dark brown soaked no change
•   cup colour is the same and no change
• bread is green and rotten

Conclusion:
This experiment was very disgusting. I didn't like it at all. The was a complete difference in 3 weeks. But this did turn out how it was supposed to and my guess was correct that the banana was going to rot the fastest There is also a very  big difference from 3 weeks to 5 weeks.

The Importance of sleep.

The Importance of sleep.

• What does sleep do for our brain and body TAHA TINANA?

In kids and teens sleep helps us to grow

Make our body rest

Sleep helps you think clearly, and get more done Good sleep keeps you heart healthy and stops us getting sick to easy.

Even though we are asleep our organs are hard at work repairing cells.

If we don't get enough sleep we are more forgetful, and problem solving is harder.

• How can sleep help to increase our TAHA HINENGARO?

Not having enough sleep can make us moody, emotional (cry easily) , and get angry easier.

We can easily overeat when things don't go our way, or not get as excited when something good happens.

Lack of sleep puts us at bigger risk for depression and anxiety.

• Sometimes it can be difficult to get to sleep - share some top tips for getting to sleep.

Count sleep

meditate

dark room

quiet/calming room

salt lamp helps

no devices before bed

Read a book in bed

listening to the radio and nature sounds eg: whale, waterfalls and birds chirping

Go to bed and get up at the same time everyday

• How much sleep do teenagers need?

Teens sleep 9 hours

• How much sleep do kids need?

kids at least sleep 10 hours and babies sleep 16 hours.

• How much sleep do Adults need?

Adults sleep 7-8 hours

Children normally get tired early and weak up earlier. But teenagers get tired later and start sleeping in longer.

How do we work in this laboratory?

• 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 heatproof.
• 
• 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.

My Investigation on climate change

My Investigation on climate change

ACIDIFICATION

DEFINITION: ACIDIFICATION OCCURS WHEN CO2 IS ABSORBED INTO THE WATER AT A HIGH RATE

What is happening to the oceans?

The ocean is taking to much CO2, because of that the fish can't settle by the ocean taking to much of CO2 the shellfish start to aciditate making them not able to form their shells. 

What does this do to shellfish?

They start to aciditate wish enables them to create their shells.

HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS?

DEFORESTATION

DEFINITION: CLEARCUTTING OF FORESTS

What are trees used for?

They're used for the water cycle, and transpiration and CO2 wood is mostly used for houses household items paper and pencils. 

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

ICECAP MELT

DEFINITION: Ice melting and falling into the ocean  

If all the ice melted what would happen?

The seawater will rise higher and higher The ocean would cover all the coastal cities. And land area would shrink

HOW DOES ICECAP MELT AFFECT CLIMATE CHANGE?

WATER VAPOUR

DEFINITION:

Gas water 

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

As the climate warms, air temperatures rise more evaporation from water sources

Stop Motion

Art 

On Monday for Art we have been creating the charactor for our stop  motion. I am pretty happy with what we had to do with the clay. These are an amazing charactor from the clay. My group had amazing ideas on what to make for our charactor. Here is my groups art work...

climate change

Aim: To look at climate change and the greenhouse affect

Materials

1. 1 plastic bottle
2. 1 Teaspoon Baking Soda and Citric Acid
3. 1 heat lamp
4. 1 Thermometer
5. 100 ml water
6. 1 rubber bung

Procedure:

1. Come and collect all of the materials from Mr Palmer.
2. Setting up the lights, bottles, thermometers and bungs.
3. Mr Palmer adds the baking soda mix along with 100ml of water.
4.  Wait for 5 minutes and start recording the temperature.

Variables:

All water added to the bottles was from the classroom tap

Minutes	Bottle 1: Water	Bottle 2: CO2 Gas
0	18.c	18.c
5	25.c	18.c
10	26.c	25.c
15	No Recording.	No Recording.
20	No Recording.	No Recording.
25	No Recording.	No Recording.
30	No Recording.	No Recording.
35	No Recording.	No Recording.
40	28.c	38.c

Conclusion:

The normal bottle of water didn't get as hot as the CO2 water. This is just the same as climate change. I also found this experiment interesting.

2040  documentary by Damon Gameau-

What are 2 thing you learned? 
1. Thing I don't know what could/might in 2040 and what damage
can happen.

2. knowing that there could be more electricity and power.
But which we should have more trees because they get cut down and we need vegetation.

what I would like to see in 2040?
I would like to see less litter in the sea.

Title`	Solar Energy
Aim	To find out what colour attracts the sun's heat.
Hypothesis	I think that the colour is going to be silver/Tin foil.
Materials	1x Tin foil cup  1x Clear cup  1x Black plastic bag  1x Small black bag  1x Heat lamp 1x White paper 1x Thermometer 1x Tin Foil  1x Plastic cup
Steps	Collect the equipment  Set it up, Put the white, tin foil and the black bag on the table. Put with clear cup on the black bag in the middle Put the little black bag over it Put the white cup in the middle of the white paper Put the tin foil paper in the middle of the tin foil  Plug in the heat lamp  Pour the water   Wait 15 minutes Record your findings
Data/Findings	Time  Cup 1 White Cup 2 Black Cup 3 Tinfoil 0 16.c 16.c 16.c 15 20.c 25.c 19.c 30 20.c 35.c 20.c  45 20.c  30.c 20.c   This is a photo of all of the cups. Throughout this the black one spilled as we let the thermometer.  The highest was the black one even though it was on the side. The lowest was tinfoil and white because the black plastic to heat water.
Conclusion	In conclusion my findings in the experiment stat that  The highest was the black one even though it was on the side and the lowest was tinfoil and white.
