Acid Rain Experiment

Acid Rain Experiment 

What is acid rain? Acid rain is when the air gets so polluted with fossil fuels it gets absorbed by the clouds and comes out in an acidic form when it rains, it is environmentally harmful.

Aim: To observe effects of acid rain

Hypothesis: Petal- dry out calcium carbonate- become liquid apple-dry out, universal indicator- get dark bromothymol blue- lighten. 

Method: In a petri dish place items around weigh boat which is in the middle of the dish, wet-dry ingredients with a drop of water.  Add a spatula of sulfate to weigh boat, add 5 drops of sulfuric acid. quickly close. 

observation: bromothymol blue is turning yellow/orange, the universal indicator is turning pink, the petal is getting slightly lighter. I think it's because acid eats way at things so it diluted the colour.

Atomic Science: Periodic Table

 What does the periodic table show us?

The periodic table shows us the elements, it is arranged by their atomic numbers and electron configuration 

What is a mass number? It shows us the mass number which is the number of protons and neutrons in a nucleus. 

What is an atom? An atom is a very small particle that makes up everything around us, it consists of three particles, electrons, protons, and neutrons. 

What are alkali metals?  An alkali metal is any of the six chemical elements that make n Group 1 of the periodic table. It's the first collum on the periodic table-  lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They react with other elements because they want to get rid of the one-electron they have. 

What happened during the demonstration? The teacher put lithium into the water and it changed the colour, then she used sodium and it created a small fire on the water but in the end, it made a small explosion.

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind Manager

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. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

• Record how many times it spins and record it in the table below.

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

	Place name on school grounds	Number of Spins in 15 seconds

2.	Old j block site	15

Beaufort Wind Scale

Beaufort Force	Wind Speed (KPH)	Spins	Indicators	Terms Used in NWS Forecasts
0	0-2	0	Calm; smoke rises vertically.	Calm
1	2-5	10	Shown by direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	Wind felt on face, leaves rustle; ordinary vanes moved by wind.	Light
3	13-20	80	Leaves and small twigs in constant motion; wind extends light flag.	Gentle
4	21-29	130	Raises dust and loose paper; small branches are moved.	Moderate
5	30-39	190	Small trees in leaf begin to sway; crested wavelets form on inland waters.	Fresh

CONCLUSION: 

On the field there were 80 spins per hour and the wind speed was 13-20 km/hr.

At the old jblock site there were 60 spins per minute and the wind speed was 12-14 km/hr.

At the grass hill there were 40 spins per minute and the wind speed was 6-12 km/hr.

At the tennis court gate there were 12 spins per minute and the wind speed was 2-5 km/hr.

Defintions- Science

Today in science we have watched  a video of different weather patterns and disasters that have happened around the world and have been caught on camera. We then had to find and write the definition for the words below and have a good understanding of what they mean.

1. Anemometer -  A tool used for wind measuring purposes.
2. Beaufort wind scale - Used for measuring wind speeds at sea.
3. Typhoon - Tropical storm, With wind faster than 74 miles per hour. ( Tropical cyclone)
4. Monsoon - Wind that carry's heavy rain. Seasonal change in direction. 
5. What is it called when the weather is really nice and it suddenly turns into hail?        Air pressure. (barometric pressure)       Climate change

Climate change

My Investigation on climate change

ACIDIFICATION

DEFINITION:

What is happening to the oceans?

It is obsorbing the C02 which is carbon dioxide as a result its making more acid.

What does this do to shellfish?

The wont grow so the fish won't be as big so people won't be able to eat it.

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

Ocean acidification is decreasing levels of pH in the ocean, which makes the sea more acidic. It is the long-term change in seawater  due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.

DEFORESTATION

DEFINITION:Trees being cut down

What are trees used for?

Oxygen- To help us breathe.

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

It is stopping the water cycle from working which means odd things are going on such as floods ect. It can stop oxygen from getting released and more carbon dioxide will be released and it works as a green house gas, Trees collect water when it rains if people keep cutting down the trees carbon dioxide will be released.

ICE CAP MELT

DEFINITION: melting ice

If all the ice melted what would happen?

There is 13 million cubic meters of ice. Antarctica contains 70 % of the earths water. The world would feel it if the ice started to melt. Sea levels would rise by about 60 meters. central china would entirely disappear. Any where between 1-2 billion people could be displaced.

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?

Sea levels would rise, Salt levels would go up which could kill lots of marine life.

WATER VAPOUR

DEFINITION: water rising 

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

 As the climate warms, more evaporation from water sources and land occurs, air temperature rise,  therefore  increasing the atmosphere moisture content.
