Group Investigation.

Groups size: 5 
Roles:

  • Timekeeper ( watch)
  • Counter
  • Recorder ( chromebook or refill )
  • Anemometer Manager ( Anemometer)
  • Wind Manager

Instructions:
  • Go to the measuring place and set up your wind gauge.
  • Make sure everyone in your group is ready to start their roles.
  • Record how many times it spins and record it in the table below.
  • Count the number of spins in 15 seconds.
  • Record it on your chart.

  • USING A4 PAPER DRAW YOUR RESULTS ON A GRAPH.
  • TAKE A PICTURE OF THE GRAPH AND UPLOAD IT TO YOUR BLOG
WHICH IS THE WINDEST AREA AND WHY?
WHICH IS THE CALMEST AREA AND WHY?
WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?

CONCLUSION:


In this science project we did Measuring weather in this blog and as you can see you will notice the list like how many Spins per minute

Solar powered oven.

Aim: To make a solar powered oven.

Materials: 
  1. Sellotape
  2. Scissors
  3. Pizza box
  4. Straw
  5. Marshmallow 
  6. Biscuit
  7. Glad wrap
  8. Tinfoil
  9. Black plastic
  10. Ruler
  11. Vivid marker   
Steps:
  1. Cut out the flap on the lid of the pizza box so that it is Sun around the edge
  2. Sellotape some tinfoil on the inside of the flap.
  3. Sellotape some glad wrap so that the hole you have cut on the pizza box lid 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 fit 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 on 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.

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:
  2. Is it used in NZ ?
  3. Other Countries that use it?
  4. How is it used to generate electricity?
  5. 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.


Section 4: Renewable Energy in the future.

List 10 ways that renewable energy will be used in the future to replace our current activities.

Group Investigation.

Groups size: 5 
Roles:
  • Timekeeper
  • Counter
  • Recorder
  • Anemometer Manager
  • Wind Manager
  1. Mount the anemometer in a place that has full access to the wind from all directions.
  2. When the time keeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
  3. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

  • Record how many times it spins and record it in the table below.
  • You will need to time them and count the number of spins.
