Ocean Acidification - Science

• How have humans contributed to ocean acidification?

Humans are producing too much Carbon Dioxide

• How is ocean acidification affecting organisms in the ocean?

There are fewer of the minerals that they need

• Why is the rate of ocean acidification alarming to scientists?

Because if this keeps going on the oceans will be too toxic to go in

• What can you do to reduce the effects of ocean acidification?

Reduce, Reuse and Recycle

Drive less
Ocean acidification over time

• How could we do an experiment in our classroom that investigates the effects of acidity on shellfish and coral? (Hint: both are made from calcium carbonate, what could we use to model/instead of their shells? Google!)

Design a small experiment that would give use more evidence for the dangers of ocean acidification on these animals. What would you need, what would you do, and what would any results tell you? (I will pick a few of the best explained experiments for us to actually do in class)  You can include images if you like.

Instead of their shells we can use chalk, limestone or marble since they’re all made out of calcium carbonate.

We could use a sodastream to produce the carbonated seawater and then put the chalk or limestone in and expose them to different levels of acidity and see the change after an amount of time.

------------------------------------------------------------------------------------------------------------

For our experiment we put eggs in different types of liquids.

One is in coke, another in vinegar, and the last is in regular water.

The coke and vinegar are to represent the different levels of acidity in the ocean.

We are using eggs to represent the coral and shells because egg shells also contain calcium carbonate.

  

Coke -

After sitting in the coke for several days the shell was cracked and the colour of it had darkened. It had also rotted on the inside and the shell is now harder to break than a regular egg shell.

Vinegar -

There wasn’t much left of the actual shell after a few days. It had completely lost it’s brown colour and kind of looks like a snake’s egg. It is now bouncy and squishy.

Water -

No change.

My response:

My evidence:

97% of scientists say that global warming is real.

My response:

My evidence:

It’s summer in the southern hemisphere so it must be winter in the northern, that’s why it is cold and snowing.

Forensic Scientist Essay - Social Studies

This essay will explain what key criteria, skills and qualities in order for to become a forensic scientist. It will also explain what it is like in the day to day life of a forensic scientist.

There are many key criteria required to become a forensic scientist. The key criteria to enter this job is the need to have a  Bachelor of Science majoring in an element of forensic science such as Chemistry, Biology, Physics, Medical Laboratory Science, Biochemistry etc. This depends on which part of forensics you want to specialise in. 3-5 years of training is required and they prefer you to have taken Science, Math, Chemistry, Biology, English in school. These are the key criteria needed to become a forensic scientist.

In order to become a forensic scientist there are many skills and qualities needed. The skills needed for this job are knowledge of poisons and drugs, research analysing and interpreting skills, knowledge of the chemical makeup of things such as blood body tissue and DNA, practical skills for performing experiments. Personal qualities needed are to be good at problem solving, eye for detail, communication skills, able to work well under pressure. These are the skills and qualities required to enter the job of a forensic scientist.

The day to day life of a forensic scientist requires a variety of different and hard activities. Most of the day of a forensic scientist is spent doing paperwork, working alongside detectives and the police on cases that you’re assigned to. Other times you’ll be working in the laboratory to analyse evidence from crime scenes. You’ll also have to go to crime scenes to examine everything and then go back to the lab to look over the corpse. Occasionally You’ll have to go to court to show evidence. For example you could be called to check out a crime scene and you’ll go have a look at the body and try to find evidence. Later on you would go to the lab to analyse the evidence found at the scene and to examine the body. After that comes the paperwork. This is the day to day life of a forensic scientist.

In conclusion, There are many key criteria, important skills and qualities that are required to become a forensic scientist. Some of these are having a Bachelor of Science, able to work well under pressure, knowledge of drugs and the makeup of DNA etc. The general day of a forensic scientist involves paperwork, working in the lab and sometimes going to crime scenes or to court.

Outsiders Essay - English

In the novel ‘The Outsiders’ there were many important conflicts between the characters.

An important conflict in the ‘The Outsiders’ was the one between Ponyboy and his family. For example there was the conflict between Ponyboy and Darry. Darry was hard on Ponyboy and we see this when Ponyboy was late home and Darry slapped him. This is showing the readers the responsibility Darry has looking after Ponyboy and Soda. The authors purpose of this was to show us that family will be hard on you sometimes but that just shows that they care and are just protective. This reminds me of ‘Pretty Little Liars’ when Aria’s fiance think she’s starting to hate him but she’s actually doing a lot of things to protect him.

Another conflict was between the greasers and the socs. We see this during the rumble where both gangs were fighting each other. The makes us understand the relationship between these two gangs. S.E. Hinton’s purpose of this was to show was gangs are like in real life. This can be juxtaposed with ‘Teen Wolf’ where Scott and his friends fight against the chimeras.

There was also a conflict between Bob and Johnny. We first see this conflict when Bob jumps Johnny. Then later on in the book  Johnny stabs and kills Bob. This makes the readers worried for what will happen to Johnny next. The purpose of this was to create a storyline for the whole novel. It was all based around this conflict. This can kind of be be compared to ‘Supernatural’ where Azazel starts a conflict with the Winchesters and is later on killed by them.

Lastly there’s the conflict between the three brothers. Ponyboy, Darry and Sodapop. Near the end of the book Soda gets annoyed at the other two for fighting and runs off. This shows us how soda feels about Ponyboy and Darry fighting. The purpose was to show how it can feel to be in the middle of someone’s conflict.
