Wind speed - Making an anemometer.

Anemometer

MATERIALS

  1. pencils
  2. tape  
  3. straws x4  
  4. pin  
  5. cups x4  

STEPS

  1.   stick the straws together
  2.   then you tape them so they are in the shape of the cross
  3.   stick a pin though them
  4.   stick it to the rubber of the pencil
  5.   stick cups though the straw
Once you have made an anemometer we are going to record the wind speed.

Group size: 5

You will need:

Anemometer (above) 

Roles:


  • Timekeeper
  • Counter
  • Recorder
  • Anemometer Manager
  • Wind generator
  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
1.1013
2.1013
3.106
4.1027
  • Can you make a statement connecting the number of spins of your anemometer and the speed of the wind? 

CONCLUSION:

this is a great way to see how fast th ewing is travelling and how strong it is

Biofuels

RENEWABLE ENERGY

Aim: To compare the amount of gas that is produced from different types of biomass.

Material:
  1.   bottles x3
  2.   permanent maker
  3.   disposable  gloves
  4.   cup
  5.   fresh horse manure
  6.   mashed banana
  7.  funnel
  8. water
  9. balloons
  10. vegetables peelings
Steps:


  1. label all bottles
  2. take bottle cap off  
  3. put manure in all bottles    
  4. put mashed banana in one bottle 
  5. and put veges scraps in the another 
  6. then you put some water in it
  7. then you put some balloons over the bottle top 
  8. and then you leave it for twelve days

water cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

e

A green box with icons and white text. Text reads: Where is Earth's Water? 96.5 percent is in the oceans; 1.7 percent is in lakes, rivers, streams, and soil; 1.7 percent is in polar ice caps, glaciers, and permanent snow; 0.001 percent is in water vapor in Earth's atmosphere

Scientific words:


  • Evaporation. When water is heated by radiant energy it turns into water vapor.
  • Transpiration. Evaporation from plants.
  • Condensation. When water vapor cools, molecules join together and form clouds.
  • Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.

  • Acidification: the action or process of making or becoming acidic.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle
Bag 2: Water cycle with CO2 added: like Oceans in climate change
Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

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

Conclusion:






Draw a labelled diagram of the Water Cycle

Water cycle words:
  1. Precipitation
  2. Hurricanes
  3. Acid rain
  4. Evaporation
  5. Carbon Dioxide
  6. Water
  7. Deforestation
  8. Water vapour
  9. Transpiration
  10. Flooding


TODAY YOU WILL BE INVESTIGATING THE EFFECTS THAT CLIMATE CHANGE HAS ON THE WATER CYCLE.

  1. Using your SOLO hexagons poster write a paragraph about the different aspects of climate change.
  2. Write about the following Climate Change concepts:
You can do these by powerpoint, embedding a movie , on your blog, on a doc or any other form of presentation. It is up to you.

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

Ocean acidification refers to decreasing levels of pH in the ocean, which makes the sea more acidic

RENEWABLE ENERGY

Renewable Energy film


Aim: To compare the amount of gas that is produced from different types of biomass.

Material:
  1. (3x) plastic bottle
  2. 3 balloons
  3. permanent marker  
  4. disposable gloves   
  5.  Cup
  6. Fresh horse manure 
  7.   mashed banana 
  8.   funnel 
  9.  water. 
Steps:


  1.  Label the bottles... Horse manure... horse manure and mashed banana... Horse manure vegetable peelings.
  2.  Place one cup of manure in one bottle and fill the bottle and leave a little room in the bottle for air.
  3.  Place one cup of manure in the bottle and add mashed banana and fill with water and leave a little bit of air.
  4. Place the ballons on the 3 bottles.

Write a definition of fuel.
Write 8 sentences about fuel. 
  • How is it made? 
  • Where is it made? 
  • What is it made with? 
  • What countries use it? 
  • What uses will it have in the future?
