Science - Water cycle

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

Definition:

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:

 
 
1.  Plastic bag
2.  Vivid Marker
3.  1 cup of water
4.   2 drops of food colouring

Steps:

1.  On your plastic bag draw out the layout.
2. After that write write that represent the process of water.
3.  Then pour 1 cup of water.
4. After the water is poured put in 2 drops of blue food colouring.
5. Then display them in a place that the sun will shine on

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	No
Amount of Water	2	2	2
Acidity	1	2	1

Key: Water and acidity amount: 1 = none 

2 = small drips

3 = large drips

Ice melting cap

  NASA has estimated that the polar ice caps are melting 9% every ten years, which is an extremely alarming rate. If the temperature on earth continues to rise at its current rate t            he Arctic will have no ice by 2040. The Arctic ice cap has decreased since the 1960s  by as much as 40%. 

Paper bag puppets

So on Tuesday we made puppets  and did a play with them about healthy food and unhealthy food my group did a song with our play. so now I will be telling about being / healthy and how it relate to hauora so healthy food is good for your body and your health

being physically active

On Tuesday we did  interviews on what people liked and who they want to be  so they wanted Tehya be a  netball player.  I was nervous to go up in front of the  class but that what we have to do in drama. and we had to ask them questions.

 five  ways to be physically fit
1.  go for a run  around the block
2 go to the gym
3 do exercise
4   get 8 hours of sleep

creative writing

My goal was to find the underworld I have been trying my hardest to find  the underworld. Then one day I found a crack in the ground it was quite big   and someone said come down here I went down and I finally found the underworld it was really awesome to find it. Then I heard a big  boom I went back up to see what was going on there had been and explosion because  someone was testing an experiment and added the wrong ingredients. When I got home my dad had a surprise it was a hover scooter it went super fast.

climate change

What is our greatest threat in thousands of years?

climate change 

How do we see climate change affecting the globe?

                                                   flooding   high sea levels  crazy storms

What is needed to change history?

people  polluting  the atmosphere with fire fuels and other poullutants

Is climate change a man made disaster?

yes because  so many fossil fuels 

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

10 years 

Why is our climate changing?

because overusing fossil fuels 

What is causing the warming trend of the climate?

burning off fuels 

What is the main problem?

increasing heat 

What are examples of these?

creatures  die and habitats are destroyed

Burning fossil fuels releases what gas?

carbon dioxide 

How much hotter now is our world?

1deg c warmer overall

What do we call this global warming?

climate change 

How is this affecting creatures / animals like bats?

they die in the heat 

What percentage of species are near extinction?

8%

How could this effect the world ecosystems?

food chains would die off people and animals could starve 

What global change was seen and recording breaking last year?

fire burning out of control

How is climate change affecting our weather systems?

1. more storm

2.more flooding  

3. ice melts 

What is another effect of climate change?

Seas rise

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

Land will be lost

How does this affect people?

They lose their houses and livelihoods

What other things affect oceans change?

oil

spills and plastic pollution

What does too much heat do to the coral?

it dies

Why did some industries not want to stop burning fossil fuels?

They want to keep making money

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.  the ice melting  
2.   water level rising 
3. carbon dioxide          
4.                          Investigate the different Fossil Fuels listed?

1. Coal
2. Oil

Write a paragraph and upload an image about each of these renewable energies.

Solar

solar energy is  radiant energy by the sun 

Wind

electrical energy obtained from harnessing the wind with windmills or wind turbines 

Waves

power obtained by harnessing the energy produced by the waves

Hydro

Hydro power plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

Write a reflection about what you have learnt about Climate Change and how it is going to affect  

i have learnt a lot about climate change  and how it affecting  the world  and affecting the polar's habitat .

10 ingredients and salt water

Task 2: Place your household chemicals from your first chart into a second chart that has two compounds together. An example has been made below.

Note: You will need to use the internet to find out how these compounds react together.

When a reaction occurs between compounds / elements there is always an end result in the form of a solid/liquid or gas. This always results in a new element being formed. For this process to occur, one of the results can be hot or cold.

Compounds (ingredients)	Method (what to do)	Chemical recation
1 baking soda 2 vingerg,	Half cup of baking soda A few drop of vinegar	Adding vinegar to baking soda gives you an immediate reaction. Adding baking soda to vinegar, the reaction is delayed, but then fizzes the same amount.
1.bleach 2.  Baking soda	Mix 1 to 2/3 cups baking soda, ½ cup castile soap or other quality liquid dish detergent, ½ cup water, 2 tablespoons of white	When bleach and baking soda are mixed, the cleaning properties of both are improved. ... This happens when only 1/2 cup of baking soda is added to a typical laundry load with bleach. However,bleach should definitely not be mixed with certain other common household products because toxic gases form.
1.salt 2. Lemon	1 cup lemon juice. 2 tablespoons salt	Because of the presence of citric acid, the lime juice & salt mixture will be slightly acidic. It will be tart (sour) and salty, to taste. ... When you mix salt with lemon juice, the salt will dissolve in lemon juice to some extent. However, no chemical reactiontakes place.
	for 2 tablespoons of fresh lime or lemon juice, 1 tablespoon of sugar, 1/2 tablespoon of bleach and 1 quart of water. Mix the ingredients.
