Major Inquiry

ExpectationsYou are to produce  

Either an:

ExperimentA full Scientific Report including Introduction, Method, Results (graph and table) & Discussion  (approx. 1000 words)


Or a...

Report1,250 words in essay form (introduction, paragraphs, conclusion).  Talk to McWhirter to get advice on how to structure it.

And

Formally present your findings to the class in a verbal presentation.


Lessons allocated: Thursday 11 November - Friday 18th November 

Presentations:  Tuesday 22nd and  Wednesday 23. Verbal presentations will be peer and student assessed. 


Links: EXPERIMENTS
Step-by-Step Self Assessment Guide (for experiments) A guide on how each section is awarded, and some things to look out for

Experiment Rubric: A short guide to the differences in each section at, above and approaching the grade standard

How to Write a Killed Above GS Discussion Paragraph by paragraph guide to writing a good discussion.  Bear in mind, simply following the guide without strong reflection or research into your own experiment, won't give you an Above GS mark!

How to Write an Introduction (Science Report):

- Start by explaining the broad ideas of your experiment (ie if your experiment is about memory do a bit of general research about how memory works)

- Move into more specific ideas to do with your experiment (ie if your experiment is comparing memory to gender, just reflect on whether studies have looked into this before)

- Move into your aim and hypothesis: There is no need to repeat this in other sections - but you may wish to put this in a separate section. 
Here's an example of a good introduction to do with bacteria
Links: REPORTS
How to Write a Sick-As Science Report
Report Rubric Be aware there is no need for a title page, although a thesis statement would be good.  To get Above Standard on bibliography you should be using 5+ references of excellent quality (ie. .gov, .edu, or from science websites or similar) and they should be referenced with citethisforme.com

Endocrine System: Diagnosing your patients

Diagnosing your Patients
Image from http://humanbiologylab.pbworks.com/


What's this funny smell?
A funny smell in urine can be an indication of ketones being present. 
Ketone bodies are acids made when your body begins using fat instead of carbohydrates for energy. When there is not enough insulin to get sugar from the blood and into the cells, the body turns to fat for energy.  A well known ketone is acetone (used in nail polish remover) and it smells bad! Read more about ketones here

Possible Diagnosis: Renal Tubular Acidosis 
Is a form of kidney disease where the kidneys fail to sufficiently acidify the urine.  Urine normally should be around pH 5-7 - but patients experiencing RTA will have a more alkaline urine. Causes for this can be an deficiency of the hormone aldosterone, produced by adrenal glands.  As the urine is not being sufficiently acidic, the H+ ions are passed into the blood, causing an intense burning pain near the kidneys.  Associated with this can be protein in the urine, which are broken down during the acidifying process. Read a bit more about it here


Possible Diagnosis: Ketacidosis:
This is caused when the body exhausts its stores of glycogen (glucose) and starts burning fat for energy.  This leads to a build up of ketones, which are a waste product of fat breakdown. 
Ketones are acidic in nature which then causes acidic urine.  Three main causes of ketacidois is excess alcohol consumption, diabetes and starvation. Read a bit more about it here


Possible Diagnosis: Diabetes:
Diabetes is caused when the pancreas does not produce sufficient amounts of the hormone insulin to regulate blood sugar levels.  This causes excess sugar to build up in your blood.  As a result your kidneys are put into overtime, as they normally send all glucose back into the bloodstream.  The kidneys begin sending glucose into the urine.  The excess glucose in the blood stream also dehydrates the cells - which normally are higher in glucose levels than the blood.  This dehydration causes the patient to feel thirsty but also urinate more frequently.  Ketones in the urine are also a symptom of diabetes, when blood sugar crashes and the body begins synthesizing fats for energy.  Read more about it here


Possible Diagnosis: Kidney Infection from Yeast Infection:
Yeast infections commonly occur when a patient is taking antibiotics.  Antibiotics,while killing 'bad' bacteria also can kill off 'good' bacteria.  Antibiotics do not act on yeast (which is a fungi), and yeast growth is usually kept in check by good bacteria.  Hence, when the good bacteria die, yeast proliferates.  Kept unchecked a simple yeast infection can travel up the urinary tract into the kidneys and cause kidney infection.  This is dangerous, as an infected kidney can easily infect the blood. 
Kidney infections are not likely to be caused by hormones: Read more about it kidney infection

We human's have pretty good vision - but what don't we see?

We don't see things outside our attention, 

.....but this can be improved through practice *sign in with your facebook account*


We don't see things outside our periphery, 



We don't see the entire colour spectrum, unlike the mantis shrimp.

Some of us don't see many colours at all: Try the colour-blindness simulator

We don't see UV light, unlike birds


We only see at a certain speed, unlike dragonflies




We don't see objects without certain cues.... like the spinning girl.  Find the explanation here.

Reaction Experiment


Your Task:

Conduct a quick and simple study which investigates factors effecting reaction time.

Use the article above to help you decide what might be an interesting question to ask.

Once your question is decided:

1. Make a prediction about what you expect to find.

2. Write a method on how you will study this
- It should be detailed sufficiently that someone could reproduce your experiment exactly as you did it
- It should be written in dot point or list for
- Ideally it should be written in past tense
- You should not refer to 'I', 'we', 'us'.


3. Write up a results table ready to take results
- Look under the 'resources' tab to get some tips and tricks for using Excel

-----------


Writing Your Report:
*HINT* Use the Inquiry Resources under the 'Resources' tab for help.

This is a simple inquiry to give you some practice in the skills you will need for your major inquiry (next term).  Therefore you won't need to include all the usual sections or put the same amount of detail in.

Your simplified report should include:
1. Aim & prediction
2. Method (detailed)
3. Results table and graph
4. A short discussion of what you found.
-- This is where you discuss your results (and graph) and then compare this to the research of others.
--Look at the 'How to Write a Killed ABGS Discussion' in the Resources tab.
 --Be sure to include some research from the internet about it, there are some helpful links below

Main Reading Reaction times vs Reflexes

Influences on Reaction Time (This article is long and has a lot of unnecessary info, but you may find it has some easy to understand information that relates to your experiment)

More Influences on Reaction Time (Again, find the section that relates to your specific experiment - try and ignore any confusing information!)

Volcanoes Assignment


This assignment has two parts. 

 Part 1 is the Google Earth mapping activity which aims to get you familiar with the processes that form volcanoes.  You will need to download Google Earth.

Part 2 is designed to get you to learn about how volcanoes played a part in three major events.  This will help you learn more about these events, in preparation for your next assignment.


Part 1: Identifying modern day Volcanoes, Earthquakes, and their causes

You will need these files for this activity: 

Understanding Crust Types and Boundary Types
Understanding Plate Tectonics (interactive website - the section slip, slide, collide is specifically about volcanoes)

Download Google Earth 
Download Google Earth

The Data Files 
You will need to save this file to your computer
Plate Tectonics ExercisIf it won't open ask the relief teacher for the USB stick, or ask a friend who has had it emailed to them. 

Part 1: ACTIVITY
1.  Download Google Earth on your device. School computers should have it on their already.  Press the windows button+S and type “Google earth” to find it.  If it is not there, you can download it from the net (a box will pop up on downloading for a teacher to authorise this).

2. Download the Google Earth Data files (on the blog) and save them in a folder.

3. Open Google Earth.  Click ‘Open’ and select ‘Plate Tectonic Exercise’

4. The data for the Plate Tectonic Exercise is now on the left hand side of the screen.  Deselect everything in the Plate Tectonic Exercise folder except for ‘Global Volcanism Program’.

5.  Zoom in until you begin to see the red triangles indicating volcanoes.

6.  Use the Google Earth volcano data to draw on your physical map the areas which have high volcanic activity (don’t worry too much about isolated volcanoes like those in the Pacific Ocean).  Use a key and label this ‘Sites of high volcanic activity’.

7. Deselect ‘Global Volcanism Program’ and now select ‘All EQuakes’.  Zoom in if you cannot see all the Earth Quake Activity.

8. Use the Google Earth earthquake data to draw on your physical map the areas which have high earthquake activity (don’t worry too much about isolated earthquakes like those in the Atlantic and Pacific Oceans).  Use a key and label this ‘sites of high earthquake activity’.  Take special note of the earthquake depths (draw in the progression of depths if you wish). 
9.  Finally deselect ‘All EQuakes’ and select ‘Plate Convergence’ (it’s towards the top of the folder).  This is a series of arrows points to spots where two plates are converging
10.  Draw these arrows onto your physical map.
 

PART 1: QUESTIONS: Write on back of map or type up.

a)  What is causing these areas to have such high volcanic and earthquake activity? (1 mark)

b) Use the resources available on the blog to explain why these zones lead to high volcanism.

c) Use the resources available on the blog to explain why these zones lead to high earthquake activity.
 
d) Why in some areas do you tend to get clear lines of  earthquakes that go from shallow, medium to deep depths?  Give an example of an area you found on Google Map where this is evident.  Use the data on Google Earth about Earthquakes to back up your statement. 


PART 2: Significant Volcanic Activity in History

Event 1: First Life
 Q1. The Miller Urey Experiment was crucial for testing the hypothesis that first life formed in “a warm little pond” from the combination of nutrients and proteins 3.8 billion years ago.

What was the Stanley Miller experiment and what did they find? Take notes from the following video to answer this question (dot points fine)  (5 marks)

Stanley Miller: Stated Clearly

Q2.  Since the Miller-Urey experiment scientists at NASA believe volcano action was crucial for providing these nutrients.  Use the link below to identify how volcanoes may have been crucial in providing the first elements for first life – dot points (in your own words) is fine.  (4 marks)

Volcanoes and First Life 



 Event 2: Snowball Earth

Q1. Use your notes from the film ‘Snowball Earth’ and further research on the internet, identify the role of volcanoes in ending Snowball Earth and giving rise to the first multi-cellular life.  Please reference your writing using either (Catastrophes dvd Snowball Earth) and/or the url from the websites you use.  Ensure to include information about greenhouse gases.


Event 3: DVD “Planet of Fire”

Q1. Watch this video either on your computer or phone from the URL https://www.youtube.com/watch?v=00ILddHJlKw

TAKE NOTES AND SUBMIT THESE AS PART OF YOUR ASSIGNMENT.

Due on Friday August 5 :
1) Your coloured in map and answers to the first part questions
2) Answers to Event 1 and Event 2 questions
3) Notes from the film "planet of fire" > handwritten and attached to map is fine.

Plate Tectonics: A force that shapes our Earth

So far we have looked at three key events:

1.  The formation of the Earth and Moon
2.  First life forming
3.  Snowball Earth

We have also looked at how currents work and how they affect our environment.

During your assignment next week you will be exploring how volcanoes have shaped our planet.

THURSDAY:
Before launching into looking at volcano based events we need to understand:

How do volcanoes work and what drives these processes? 

This leads us to our next event:

4. Movement of the Earth's tectonic plates (aka continental drift)

To Do:

Move through the Dynamic Earth Interactive (from intro until the Quiz)
Pay particular attention to the section slip, slide and collide 

Dynamic Earth Interactive
