Decomposition🥀

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

Hypothesis: I think that banana is going to decompose the fastest.

Materials:  

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

Steps:

1.   Put the test tubes into the stand.
2.   Put the banana in one tube, the paper in another tube, Etc.
3. Put water into the bread tube.
4. We took it back to our table.
5.  We Wrote our names on a piece of paper and stuck it onto the stand.
6.   Placed the stand onto a surface where it won't be touched.
7.   Wait 5 weeks

Findings:

TODAY	Colour	Change	Observations
Banana	Yellow	-	-
Paper	Brown	-	-
Styrophone cup	White	-	-
Bread	Beige	-	-

3 weeks	Colour	Change	Observations
Banana	brown and a greenish colour.	Changed colour and rotted	the banana went from a smallish yellow piece to a brown disgusting smelly mess.
Paper	Brown	Nothing	Nothing had changed about the paper it was still brown and looked the same.
Styrophone cup	White	Nothing	Nothing had changed about the cup it was still white and looked the same.
Bread	Green, black and white	Change of colour	The bread was a normal beige colour at the start but slowly started changing colour.

5 weeks	Colour	Change	Observations
Banana	green	Changed colour.	The banana had gone very mouldy and disgusting.
Paper	brown	nothing	It looks the same
Styrophone cup	white	nothing	Looks the same.
Bread	white, brown and a creamy colour.	mouldy foam on the top.	The bread had turned into white mouldy foam and the water had turned into a beige creamy liquid.

  

Conclusion:
I personally think the banana moulded the fastest because in 3 weeks it had already started to look like the end result, The bread had also moulded very fast. In conclusion I don't think anyone should ever do this its very gross and smells.  

The Greenhouse Effect☂

Aim: To look at climate change and the greenhouse effect

Materials📋

1x Plastic bottle

1x Teaspoon Baking Soda and Citric Acid

1x heat lamp

1x Thermometer

100 ml water

1x rubber bung︵‿︵‿︵‿︵‿︵︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵‿︵　　

Steps📝

1. Add 100 mL of water to each of the beakers.
2. Prepare your lamps. Set them up next to each other with the necks angled
   so they will just fit over the tops of the bottles.
   Turn them on so they are ready.
3. Add Baking Soda mix to one of the beakers,
   and immediately cover both beakers with cling a rubber
   bung and thermometer. A tight seal around the edge will work best,
   and make sure thermometers are left visible so you can record the
   temperature.
4. Have students record the starting temperature –
    it should be the same in both beakers.
5. Turn the bottles so the thermometer is visible.                             
6. Record the temperature in both beakers every
   5 minutes for 50 minutes.

The Water Cycle

This week in science hurumanu also known as Climate Chaos we cut out 10 hexagons and explained why they are together.

This week for Climate Chaos we had to cut out 10 hexagons and explain how each of them went together.

Water Cycle is connected to Transpiration because transpiration is a step of the Water Cycle.

Transpiration and Water Vapour are connected because they are all the action of water vapour going up.

Water Vapour and Evaporation are connected together because they are from water (Oceans, Lakes, Rivers, Ponds) and the watering plants.

Water Vapour and Condensation are connected by when the water vapour rises it forms together to make clouds which is also part of the water cycle.

Evaporation and Condensation are connected because (evaporation) the water evaporates and rises and it clumps together to make clouds (condensation).

Condensation and Hurricanes are connected because Hurricanes can change the climate and the surface of the earth which can lead to disrupting weather patterns.

Water Vapour and Precipitation are  connected because water vapour goes up into clouds\\

✧･ﾟ:Solar Energy

╔═══════════════ ∘◦ ☆ ◦∘ ═══════════════╗

Aim: To learn about how solar energy is used.

Hypothesis: I think that black will attract the most heat.

Materials:

1. Solar Heater
2.  Thermometer
3.  Tinfoil
4. White cup 
5. Clear Cup
6.  White Paper
7. Black Plastic 
8. Water

Steps

1.  Get your materials.
2. Set up your lamp.
3.  Cover the cups one cup in tin foil, and one cup in black plastic.
4.  Place the cup with tin foil on a tinfoil sheet, Place your clear cup with black plastic on to black plastic and finally put your white cup on a white piece of paper. 
5.   Put all the cups in a line.
6. Place them in front of the lamp.
7. Record every temperature every 15 mins.

Findings:

In pairs rate the livability of coal vs solar energy.

Comparing Coal energy with Solar energy ( Rate; 1 = poor to 10 = great)

Factor	Solar	Coal
Livability	10	4
Sustainability	10	2
Accessibility	10	3
Cost	9	5
Your choice...	10	1

Conclusion:

1. Solar power is more sustainable than coal is.

2. Sun, wind & water are all renewable energy.
3. The color black attracts the sun & heat.

Issues Of Climate Change

Aim: To learn about the different activities that contribute to climate change.

• Industry-  Factories make clothes, cars, electronics and processed fools that create pollution. 
• Transport- Most cars need gas or diesel to make them work. Gas and diesel come from oil. which is a fossil fuel.
• Waste- Landfills are covering more healthy land, and when it breaks down it makes greenhouse gasses.
• Cows- Cows create greenhouse gasses called methane when they burp and fart.
• Food- The food creates a lot of pollution, by having to transport it by ships, planes, trains, and trucks. 
• Electricity- Electricity is a form of energy used to power almost everything in our homes, Elcectrcity can come from renewable resources, but it can come from non-renewable rescourses. 

Tane Mahuta

I have decided to make a slideshow with two other people about what we have been doing in Tane Mahuta, I will be updating the slide each week and informing everyone about what we did each week with or teachers Mrs Alan and Mr Tisch. If you would like to see what we did this week head onto slide 4.

Team Reflection

This week in our P.E Hurumanu we played cross-court games

in the school gym, our focus was to work in random
small teams with people we normally would not work with.

Our activity was cross-court games. For this activity, I rated my self at level
three. To achieve at level three we have to show that we can consistently
contribute in all three games of cross-court game and always include
ourselves and others to the game. During the game of cross-court games,
I showed that I am working at level three by contributing in every game and
trying as hard as I can to include everyone in the game. These examples
show that I have met the standard for level three.

While playing the Cross-court games, something that I found challenging was
that I did not get along with the other team that well. The reason I found this challenging
was because my team and the other team would argue about the rules and say that each
other was not playing the game right. However, I managed to overcome this challenge by
finding a way to sort the problem out so that both teams were happy and if we had a problem
with how the other team was playing we would say something about it and work it out.

Next week I am aiming to work at level four. To make sure that I am working that level
I am going to work on being more of a leader and using kinda and positive words all the
time.

Community impact project-

Today we decided to do some cleaning and some plumb picking. The first thing we did was go to the garden we started by picking heaps of plumbs for something were going to make i'm not sure what were making yet but it sounds like it will be yum. After plumb picking we started cleaning up the whole compost area. We started off by picking up all the rubbish in the area while others picked up the big sticks, after we completed that we started moving all the leafs into a pile we finally completed the cleaning up so we got to look around and look for some bugs there were lots of cool and creepy little insects.

Tane Mahuta

I am part of the Tane Mahuta which is like a community project group thing. Our job is to make hornby high school a better place. Today we looked around the school at places we could improve. My personal favorite place was the field my group had some great ideas what to put there. My best idea to improve the school is to pick up alot of rubbish and put a munch of trees around the school (:

Code.Org

Today we were doing coding on code.org I had so much fun on the dancing one I enjoyed a lot this is what I managed to do. Also, you can use your keys to make the animal do things.

here's one of them: Use the arrow keys to make it do fun poses

Continuous Cricket

For hurumana were doing one period on Monday and this is what I managed to remember about continuous cricket

The objective of the game is to score the most runs.The rules of the game are The class is split into half the class. We are put into two teams the batters and the fielders. One of the fielders face the batter, the bowler will pitch the ball and the batter must hit the ball as far as they can for the best results. The batter has six runs, you can either get them by hitting the ball one-six times. To score the run you must hit the ball then run with the bat to the “base”. You can get out by either the fielders catch the ball on the full or with one hand they catch it with only one bounce, or the ball hits your wicket. The batter must run each ball even if they don't make contact with the ball.

The fielders must switch turns being the bowler. The bowler must have one foot on the “bowlers base” and underarm pitch. The bowler is the only person who can try to hit the wicket. The bowler's job is to get the batter out by trying to hit the wicket.
