Solar Energy

Catching the sun movie


Materials:


  1.  Cups x4
  2.  Water
  3.  Tin foil
  4.  2 sheets of water paper
  5.  1 sheet of black paper
  6. Thermometer
  7. 1 large cup
  8. 2 heat lamp

Steps

  1.   Get all the materials needed.
  2.  Fill the small cups up with water.
  3.  Put the cups on the respected place.
  4.  Put the large cup on one of the small cups that is on white paper.
  5.  Get the heat lamps and shine it on the cups. 
  6. Wait till a time then measure the heat of the water.

Which surface conducts / attracts the most heat?

Findings:

That findings that I have is that some cups temperature went up after the heat lamps were taken away. I think that it did that is because the room was closed in and we were talking and it heated the temperature. 


Conclusion:

My conclusion is that some water heat was different than others. Because of the material that some were on. Also the room that our cups were in was closed off. Also we were in the room so the heat of our breath had an affect on the temperatures. So I do not know if this is a precise recording.

Drama

Drama - Week 6

In drama this week we did a lot of this. Firstly we learnt a little bit about puberty, and the changes we have to go through. We learnt about the scientific names of each part of the body and the menstruation cycle.

We practice our voice and doing different tough twisters. We also looked at slam poetry and chorus work. Then we got our poems and practice performing them. Later we performed them in front of the class.

Wind speed - Making an anemometer.


MATERIALS       

Anemometer

1. 4 straws
2. 4 Styrofoam cups
3. A pin
4. A pencil
5. Tape

STEPS


1. Tape 2 straws together then do that again.
2. The pin the straws into the pin.
3. Next put the pin into the rubber of the pencil.
4. After put to hole on each side of the Styrofoam cups.
5. Then put the straws into the holes of the cups.
6. The blow the cups and see it spin.

Once you have made an anemometer we are going to record the wind speed.

Group size: 3

You will need:

Anemometer (above) 

Roles:


  • Timekeeper Chloe
  • Counter Chloe
  • Recorder Makaea
  • Anemometer Manager Shontae
  • Wind generator Shontae
  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. If possible, repeat the above step four (4) times and record the average number of spins on the chart.

FINDINGS

  • Record how many times it spins using the table below.
You will need to create the wind yourself by blowing. Get 4 different wind speeds by blowing.

You will need to time them and count the number of spins.

Time IntervalNumber of Spins
1.108
2.107
3.104
4.105
  • Can you make a statement connecting the number of spins of your anemometer and the speed of the wind? 

CONCLUSION:

My conclusion is that our anemometer was not as good as real anemometers. Also that the wind today was very calm and not ruff. Our anemometer did not work very well.
