Wind speed - Making an anemometer.

Anemometer

MATERIALS: 

  1. Pins 
  2. Cups  (x4)
  3. Pencils  
  4. Straws (x4) 
  5. Tape  

STEPS

  1.   Put 2 holes in each cup 
  2.   Put your straws in a cross 
  3.  Tape the cross of straws together (go around with tape 3 times) 
  4.    Then pin them done in the pencil with a rubber in it 
  5. Then put the cups and straws together  
 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 timekeeper 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.

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

 

Definition:

EVAPORATION:

THE PROCESS OF TURNING FROM A LIQUID INTO VAPOR.

THE PROCESS OF SOMETHING ABSTRACT CEASING TO EXIST.

 

TRANSPIRATION:

(OF A PLANT OR A LEAF) THE EXHALATION OF WATER VAPOR THROUGH THE STOMATA.

(PLANTS LOSE MORE THAN 90 PERCENT OF THEIR WATER THROUGH TRANSPIRATION)

 

PRECIPITATION: 

THE ACTION OR PROCESS OF PRECIPITATING A SUBSTANCE OF A SOLUTION.

RAIN, SNOW, SLEET, OR HAIL THAT FALLS TO OR CONDENSES ON THE GROUND.

 

CONDENSATION:

WATER WHICH COLLECTS AS DROPLETS ON A COLD SURFACE WHEN HUMID AIR IS IN CONTACT WITH IT.

THE CONVERSION OF A VAPOR OR GAS TO A LIQUID.

 

 

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.

 

WE WILL BE CONDUCTING AN EXPERIMENT THAT LOOKS AT THE DIFFERENT WAYS THAT CLIMATE CHANGE IS AFFECTING THE WATER CYCLE.

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:

 PLASTIC BAG

VIVID MARKER

 1 CUP OF WATER

  2 DROPS OF FOOD COLORING

Steps:

 GOT OUR BAG

 WE DREW EVERYTHING WE NEEDED TO ON IT.

NEXT, WE ADDED 1 CUP OF WATER

THE ADDED 2 DROPS OF FOOD COLORING

AFTER THAT, I ADDED DOUBLE-SIDED TAPE ON ONE SIDE OF THE BAG AND TAPED IT TO THE WINDOW.

Two Images:

 

Findings: It was really easy to make and do.

 

Conclusion:

Findings:

 

 


The Water Cycle: Bag 1
CO2 Water Cycle: Bag 2
Acid
Desert Water Cycle
Bag 3
Does it cycle?

                                                  Key: Water and acidity amount: 1 = none 

2 = small drips

3 = large drips

 

Other comments:

1. Water cycle 1 had no acidity 
2 Water cycle bag 1-2-3 both have a small amount of drips in them.
3 Water cycle bag 1&3 have no acidity in them
4 Water cycle 1-2-3- all cycle

 

 

Conclusion:

It was fun and learned heaps

Water cycle words:

  1. Precipitation
  2. Hurricanes
  3. Storms
  4. Evaporation
  5. Carbon Dioxide
  6. Water
  7. Oceans
  8. Water vapour
  9. Freshwater

1. Icecap melt 

2. Acidification 

3. Deforestation

4. Water vapour

 

Icecap melt definition:

A polar ice cap is a region of land at the North or South Pole of a planet that is covered with ice. ... As the polar ice caps melt, sea levels rise and the oceans become less saline.

Deforestation definition:

Deforestation is the clearing of trees, transforming a forest into clear land. You can see the word forest in deforestation.
