Hurumanu - Science: Solar Energy...

Solar Energy

Aim: To find out which color attracts the suns heat.

Hypothesis:

I think that what will happen with solar energy's or what will happen with one...

Hypothesis meaning... It means to guess something... but out of the information you already have...

I think that the black covered cup will heat up the most because of how the heat will or can get threw the black paper but also make the heat stay inside of the surrounding black paper... 

Materials:

1.  Three Plastic Cups...
2.  Tin Foil...
3. Black paper... 
4.  White paper...
5.  Water...
6. Heat lamp...

Steps

1. Collect The Materials...
2.  Pour the water into the three cups...
3.  Wrap one Foam Cup in tin foil...
4.  Wrap the others in the other materials... Black plastic...
5. Put the materials of the cup, under the cup...
6. Put the water into all three cups...
7.   set the heat lamp up so that it can reach all three cups...

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16 Degrees	16 Degrees	16 Degrees
15	18D	19D	17D
30	21D	25D	23D
45	24D	26D	25D

This is basically what we have done with the experiment...

The cups will absorb the heat from the heat lamp,

So that the water warms up...

Conclusion

I have learned to make a heat lamp for solar power or...
To make water heat up and to see what cup will heat up the fastest with a different material surrounding the cup, I have learned about what the solar energy can do to different.

Activity:

In pairs rate the livability of coal vs solar energy.

Hurumanu - Science - Orana park... Climate change :)

Aim: The aim is to write about what we enjoyed on the trip we went on to Orana park, and how climate change can affect the animals and their environment...

Orana Park - On Tuesday three classes from Hornby High School ( HHS ) went to the animal care home called Orana Wildlife Park, including myself, but we were split up into four groups...
we got to see the lions first we learned how climate change is affecting the Lions habitats,

Three things I enjoyed about the trip:

• One thing I enjoyed about going to Orana park was just seeing the animals, because when your at school we don't get to see many animals, and also they are just really fun to learn about them.

• Seeing the animals was also great... Learning how their environment will or already has changed from climate change by... Deforestation for one, deforestation has made so many problems for changing other animals' habitats and even food sources, but there are a few things that deforestation has done to sorta help the wildlife, like using palm oil.

•   Being there, To be honest, I have a favorite animal, and my favorite animals are the Giraffe Because they are tall and self less, they have to do really tough stuff too because their height is sorta a weird problem but, the will adapt to there wildlife but they still can still be hunted by many animals...  

Hurumanu - Investigation on Climate Change...

My Investigation on climate change

ACIDIFICATION

DEFINITION: The action or process of making or acidic.

What is happening to the oceans?

The oceans are absorbing the CO2, But it does take away the CO2 and that is a good thing but...

What does this do to shellfish?

The shellfish in the ocean, where the CO2 gets absorbed, they don't grow as they are supposed to or they are growing at a slower rate every year.

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

DEFORESTATION

DEFINITION: It is a wide clearing of trees in an area.

What are trees used for?

Trees help us breathe and to control the weather as well...

As for us humans breath in oxygen, we exhale carbon dioxide, so the trees take away the Carbon dioxide to make the weathers a little bit better. 

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

ICECAP MELT

DEFINITION: The melting of the polar ice caps is caused by the overall increase in global temperature, and this melting can have serious consequences for all organisms on Earth. As the polar ice caps melt, sea levels rise and the oceans become less saline.

If all the ice melted what would happen?

The sea levels would rise and close coast citys would be underwater...

HOW DOES ICECAP MELT AFFECT CLIMATE CHANGE?

WATER VAPOUR

DEFINITION: a dispersion, in air, of molecules of water, especially as produced by evaporation at ambient temperatures rather than by boiling.

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

The Vapour and water contribute by making vapor to form clouds but...

if there aren't enough clouds or if there are too much, they could mess up the weather,

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 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.
•
