Renewable Energy- Science

Aim: To make a solar powered oven.

Materials: 


  1.   Ruler
  2.   Scissor
  3.   Marshmallow
  4.   Newpaper
  5.   Tin Foil
  6.   Glab Wrap
  7.   Pizza Box
  8.   Black Paper
  9.   Straw
  10.   Selltape
  11.   Biscuit
  12.  Vivd Maker
Steps:
  1. Cut out thr flap on the lid of the pizza box so that it is 5cm around the edge.
  2. Selltape some tinfoil on the inside of the flap
  3. Selltape some glad-wrap so that the hole you have cut on the pizza box lib is covered over with glad wrap.
  4. Put a piece of black plastic on the bottom of inside of the pizza box on the bottom.
  5. Make a paper square that fits inside the pizza box and lays around the edge.
  6. Put a marshmallow on top of the chocolate biscuit, place it on a plastic plate and put it in the solar oven.
  7. Put it in the sun to cook.

Conclusion




Aim: To make a presentation that investigates different renewable energy's.

Section 1: Title Page

Make a title page that incorporates all renewable energy 's Hydro, Solar, Wind and Wave.

I have done my title page on paper.

Section 2: Definitions

Define and provide a picture of each energy type.

  1. Hydro Energy
  2. Solar Energy
  3. Wind Energy 
  4. Wave Energy

Section 3; Investigate each of the 4 Energy types.
( Hydro ,Solar ,Wind ,Wave ) 



  1. Type:
Hydro Energy- Hydroelectric energy is energy derived from the movement of waterWater has mass. It falls and flows downward due to gravity. 

Solar Energy- Solar energy is the term used to describe the light and heat produced by the sun. Solar power is the conversion of sunlight into electricity.

Wind Energy- Wind energy refers to capturing the energy from moving air, wind and converting it into electricity. 

Wave Energy- Wave energy is the transport and capture of energy by ocean surface waves and thenergy captured is then used for all different kinds of useful work, including electricity generation, water desalination, and pumping of water.
  1. Is it used in NZ ? 
Hydro/Wind - New Zealand has excellent renewable electricity resources. We've got hydro, wind and geothermal up the wazoo. In a typical year, more than 70% of our electricity comes from renewable sources, and the government wants this to increase to 90% by 2025 (for non-dry years).

Wave- yesNew Zealand is very fortunate in its wave energy resource.

Solar- I don't know.

  1. Other Countries that use it?
Hydro- Yes, There are other countries that have hydro power such as China, Canada, Brazil, the United States and Russia, they also have big land masses.

Solar- Yes,  China, United states, Japan, Germany, India, Italy, United Kingdom and Australia have Solar Energy

Wind- Yes,  France, Canada United Kingdom, Spain, India, Germany, United States and China have Wind energy.

Wave-  Yes,The Western coasts of Scotland, Northern Canada, Southern Africa, Australia, Northwest Coast of United States and particularly Alaska have Wind energy.   
  1. How is it used to generate electricity?
  2. Draw and label a diagram of the main parts of the electricity generator? This can be done on paper and uploaded or on a drawing program on your device. I do not want any Internet images or pictures. They must be hand drawn using a ruler and labelled.

Water Cycle- Science



Last week in week 6, my class and Ds has been focusing on Climate Change in Science. We did a experiment about the weather cycle and I was in a group with Sierra and Rowina. We had to get a zip lock bag and draw the weather cycle on it and add some couple of ingredients in the bag and hang it up on the glass window where there is sun shining.

Here is a screenshot of my template with the materials and steps on it:

Title

Experiment 1 and Experiment 2:
 Weather Cycle

Purpose

To understand the Water Cycle

Materials

Experiment 1:
1x Zip lock bag
1x Vivid pen
2x strips of Double sided tape
½ a cup of water
2x drops of blue food colouring
1x Scissors

Experiment 2:
1x Zip lock bag
1x vivid pen
2x strips of double sided tape
½ a cup of water
2x drops of blue food colouring
1x Scissors
1x teaspoon of baking powder
1x Litmus paper 
1x Soda water

Steps

Experiment 1:

Step 1:
Grab your Zip lock bag.

Step 2:
Grab a vivid pen.

Step 3:
Draw the water cycle on the zip lock bag with the vivid.

Step 4:
Get the 2x of the strip double tape. 

Step 5:
Stick the tape on the top below the zip and at the bottom of the bag.

Step 6:
Carefully add ½ a cup of warm water
and 2x drops of blue food colouring into the bag.

Step 7:
Close the zip lock bag and give it to the teacher to stick on the glass
window where there is sun shining on.  

Experiment 2 steps:

Step 1:
Grab your zip lock bag

Step 2:
Grab a vivid pen

Step 3:
Draw the water cycle on the zip lock bag with the vivid.

Step 4:
Get the 2x of the strip double tape. 

Step 5:
Stick the tape on the top below the zip and at the bottom of the bag.

Step 6:
Carefully add ½ a cup of warm water and soda water into the bag.

Step 7: Add 2x drops of blue food colouring into the bag.

Step 8:
Add 1 teaspoon of baking powder into the bag

Step 9:
Close the zip lock bag with the litmus paper at the tip of the zip
and give it to the teacher to stick on the glass window where there is sun shining on.

Conclusion

I think the outcome of experiment 1 is going to look the same
because it’s only blue food colouring in water. 

I think the outcome of experiment 2 is going to probably change
because you have added baking powder into the water with the blue food colouring
and also used the litmus paper in there to see if it has changed colour.

Findings:



The Water Cycle: Bag 1
CO2 Water Cycle: Bag 2
Acid
Desert Water Cycle
Bag 3
Does it cycle?
21
Amount of Water
21
Acidity
11
For bag 1 it did a small amount of the water cycle and it also had a small amount of water.
For bag 2 the water cycle was no change at all and the water didn't change. 


Key: Water and acidity amount: 1 = none 
2 = small 
3 = large 

Conclusion:

The normal water cycle did have a little movement through the cycle and the water stayed the same.

The water cycle with acid didn't do anything to the litmus paper and the water stayed the same as well.
