Wind Racer

 Aim: To make a wind-racer with materials to go the longest distance.

Method: Use newspaper as a sail then strengthen it with cardboard, then we used skewers to strengthen the newspaper so it dint bend around so it stayed straight and wind hit it evenly.

Results: 

What forces were acting on it? Gravity - Because it dint fly into space. Push - As the air from the leaf blower pushed the wind racer forwards. Friction - Friction slowed it down as it dint slide forever. Support - As the wind racer didn't fall through the earth.

Why did it slow down? Because when it goes it hits a wind going towards it and slowing it down after the leaf blower range could not reach the wind racer

Conclusion:. 

Did it work: Yes it did work my team's wind racer went  the longest distance.

What would you do differently? Another of newspaper to make it stronger and go for longer.

Materials:

1.  4 Cups   
2.  Water
3.  Tin Foil
4.  2 Sheets Of White Paper 
5.  1 Sheet Of Black Paper 
6. Thermometer
7. 1 Large Cup 
8. 1 Heat Lamp 

Steps

1.   Get all your materials 
2.  Filled all 4 cups quarter the way fill
3.  then get your one sheet of tin foil 2 sheets of white paper and your other sheet of black paper
4.  put one cup on each of those sheets 
5. Check the temperature of them all before you turn on your heat lamp 
6.   Turn on your lamp or leave them sitting in the sun
7. Check it every 15 minutes 3 times for an hour.

Which surface conducts/attracts the most heat?

Time + temperature	Cup 1 White paper	Cup 2 White paper+ plastic.	Cup 3 Black paper	Cup 4 Tinfoil
0	12	12	12	12
40 minutes	17	21	23	29
15 minutes	20	15	24	29

Findings:

I found that the  light heated the water up because light creates haeat then when wee turned the lamp off  it loses heat because the lamp is not creating heat so it drops back down too room temperature.

Water Cycle

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

1. 
   

VIVID MARKER

2. 
   

 1 CUP OF WATER

3. 
   

  2 DROPS OF FOOD COLORING

4. 
   

Steps:

 GOT OUR BAG

1. 
   

 WE DREW EVERYTHING WE NEEDED TO ON IT.

2. 
   

NEXT, WE ADDED 1 CUP OF WATER

3. 
   

THE ADDED 2 DROPS OF FOOD COLORING

4. 
   

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

5. 
   

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?	Yes	Yes	Yes
Amount of Water	2	2	2
Acidity	1	2	1

                                                  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 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

2. Acidification 

3. Deforestation

4. Water vapour

 

Ice cap 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 word forest in deforestation.

Climate Change

Aim: To look at the causes of climate change and how to prevent it.

Climate Change video; The Facts video

As you watch the video answer these questions:

What is our greatest threat in thousands of years?

How do we see climate change affecting the globe?

1.   Flooding
2.   Droughts
3.   Tsunami
4.   Wind
5. Wind
6. Global Temperature and Sea Temperature Rising
7. Carbon Dioxide, Gasses

Is climate change a man made disaster? Yes

Dramatic action must be made in the next  1000 years to change it?

Why is our climate changing? 

Because people are using gas/fossil fuel and polluting earth

What is causing the warming trend of the climate?  Burning fossil fuels that is releasing too much carbon dioxide into earth and making earth too hot.

What is the main problem? Earth is heating up 2 much and Antarctica is melting and then the water levels will rise and all of earth will go under water.

Burning fossil fuels releases what gas? Carbon Dioxide

How much hotter now is our world?  The average global temperature on Earth has increased by about 0.8 degrees Celsius 1.4 Degrees Fahrenheit since 1880.

What do we call this global warming? Climate Change

How is this affecting creatures / animals like bats? More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals.

What percentage of species are near extinction? 99.9%

How could this effect the world ecosystems? 

All the animals will be extincted.

What global change was seen and recording breaking last year?

All the animals/mammals are dyeing and getting near extinction

How is climate change affecting our weather systems?

Global analyses show that the amount of water vapor in the atmosphere has in fact increased due to human-caused warming. This extra moisture is available to storm systems, resulting in heavier rainfalls. Climate change also alters characteristics of the atmosphere that affect weather patterns and storms.

What is another effect of climate change?

What will happen if the ice melts in Antarctica and the Arctic?

How does this affect people? 

Flooding there houses and having nowhere to live.

What other things affect oceans change?As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat

What does too much heat do to the coral?

Kill the fish

Oil Pollution Climate Change

Oil is polluting our water from ship spillages and waste oil through sewage pipes

Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel drains and dumping. An oil spill from a tanker is a severe problem because there is such a huge quantity of oil being spilt into one place. Oil spills cause a very localized problem but can be catastrophic to local marine wildlife such as fish birds and sea otters.

Oil cannot dissolve in water and forms a thick sludge in the water. This suffocates fish, gets caught in the feathers of marine birds stopping them from flying.
