Term 2 Science Project (Term 2 2015)

 

Science project term 2

To conclude our science unit on adaptation students will prepare an information display with supporting resources on a desert animal or plant.

Teams will:
• describe the desert environment to which the species is adapted
• describe the structural features and behaviour of the species
• make claims about which are key adaptations that help the species survive.

Present your research on a display board.

  • All in your own words. The language should be impersonal and contain three tier words.
  • Use a font size of at least 16 points for the text on your display board, so that it is easy to read from a few feet away. It’s OK to use slightly smaller fonts for captions on picture and tables
  • The title should be big and easily read from across the room. Choose one that accurately describes your work, but also grabs peoples’ attention.
  • It should contain a least one graph.
  • A picture speaks a thousand words! Use photos or draw diagrams to present non-numerical data, to propose models that explain your claims. As well as creating an annotated drawing to (similar to the one on ‘Camel features’) you’ll be expected to construct a 3D model. This will need to highlight the features and adaptations that are central to your species’s survival in the Australian desert.
  • A Bibliography. At least three sources.
  • A proposal for an experiment to investigate if your claimed structural feature of the animal/plant is an adaptation for surviving in a desert environment. Deciding on what you and your team think you can achieve in the given time, you can either:
  1. propose an investigation
  2. plan the experiment
  3. conduct your experiment and observe, record and share the results in your final display.

A good-quality presentation is:
• well-organised information
• clear, concise communication
• use of evidence and reasoning to support claims
• quality/creative visual aids.

Examples of oral presentations by scientists on adaptations can be found at:
(www.qm.qld.gov.au/Find+out+about/Behind+the+Scenes/Museum+Experts).

Species to investigate:
• The Australian Mulga (Acacia aneura)
• Old Man Saltbush (Atriplex nummularia)
• The Greater Bilby (Macrotis lagotis)
• Spencer’s Burrowing Frog (Opisthodon spenceri, formerly Limnodynastes spenceri)
• The Thorny Devil (Moloch horridus)
• Budgerigars (Melopsittacus undulatus)
• The Boab tree (Adansonia gregorii)
• Spinifex grass, for example, Triodia wiseana
• The Spinifex Hopping Mouse (Notomys alexis)
• Shield shrimps (Triops australiensis)
• Termites, for example, Nasutitermes triodiae*

Scientific Report: Preventing Rust

Title: Preventing Rust           Class: 5/6C           Date: ?????

 

 

 

Aim: To find the most efficient and effective way of preventing rust.

 

Materials:

  • Copper Ribbon x3
  • Beaker 600ml x4
  • Vinegar (300ml)
  • Wax
  • PVA Glue
  • Bunsen Burner (Help Needed)
  • Tripod
  • Gauze Mat

 

Method:

  1. Get materials.
  2. Pour vinegar into one beaker.
  3. Place all copper ribbons in vinegar.
  4. Place tripod on top of Bunsen burner and place the gauze mat on the tripod.
  5. Place wax in one beaker and place that beaker onto the gauze mat.
  6. Turn on Bunsen burner. (With help)
  7. Wait till wax melts.
  8. Turn off Bunsen burner. (With help)
  9. Put 1 copper ribbon into the molten wax and remove the molten wax beaker from Bunsen burner.
  10. Place another copper ribbon in empty beaker.
  11. Put PVA glue onto copper ribbon (Till covered)
  12. Leave both beaker next to each other.
  13. Place last ribbon in the last empty beaker.
  14. Then observe your results in 1-2 days.

 

Hypotheses: My prediction is that the wax will be the most effective but the glue will still be better than no way of prevention.

 

Observations:

Air: Showing small signs of rust, no other reactions.

Glue: No rust, completely covered in glue and glue has not yet solidified

Wax: Wax has solidified, no rust yet and an air bubble has been trapped under the wax with the copper.

Results:

Air: Rusted completely, no other reactions

Glue: Has not rusted at all, has been successful.

Wax: Has rusted yet only in the area of the air bubble. Areas submerged in  wax completely unaffected

Conclusion: In conclusion the glue has been the only way to succeed but the wax has improved on the air and has only had a flaw exposed. Overall the experiment was successful.

Extreme Weather Project Reflection (Term 4 2014)

For my extreme weather project my partner was Lilli and our topic was floods.

Most of our research and information was generally found through prior knowledge. But on occasion we used the internet to pick up key details such as repair costs.

We used note taking on one – note yet, since most of our information was what we knew prior to the assignment not much note taking was used.

I think my partner (Lilli) and I worked well together. We both pulled out weight and regularly met to assign tasks to do in our free time. Both of us always completed our tasks on time and ended up having our project done early.

The format we used was a PowerPoint. We chose this because we had more experience using the program compared to other options.

The tasks I did were creating the PowerPoint (half with the help of my partner), answering half the questions, helping create the information and content and completing research.

Letter to the Government, Global Warming (2014)

Jordan ……

……………………..

……………………. ____

Dear Mr Greg Hunt,

 

I am writing this letter to alert you on the environmental issue of global warming. Global warming is slowly becoming a greater threat to Australia and the rest of the world.

Removing the carbon tax was a bad decision. The carbon tax stops the burning of coal in Australia; your policy for the burning of coal increases the amount of carbon Australia is releasing and there for increases the threat of global warming.

The increased amount of logging done in Victoria and Tasmania has disturbed the amount of carbon expelled out of our atmosphere. I understand that the government has to do controlled burns after certain amounts of time but cutting whole forests is different and should be stopped. You may consider that growing plantations is a solution to this problem, but plantations are regularly cut down when trees grow big enough.

I know that stopping global warming for the whole world would be extremely difficult and could take over a millennium and global warming caused by humans would have consumed most of our planets land but for the time we live on this planet we should do our best to prevent it and slow it down. So I urge you to try and help to stop the threat of global warming for Australia and the rest of the world.

Jordan, Brunswick

Letter From The Goldfields

Dear Mum and Dad,

I’ve been digging for one month. So far I’ve had no luck no luck. I’m thinking of leaving the goldfields nobody’s finding any gold anyway. I’m thinking o’ becoming a policeman, but miners say it’s a dirty duty. In the papers it says the government is desperate for police and the wage has flown to two pounds! And with a fortune I can live the luxury life in Melbourne like all desire.

Love from Mr Smith

Post. Script. You should come and work here as you could make a fortune!

The Gold Rush

In 3/4C everyone had to study a certain event in Australian history. I studyed the gold rush. Everyone had to write a Fact sheet, a Descripive piece and a poem.

Here’s my Fact Sheet:

Gold Rush Fact Sheet

When– From 1851 to 1854

Where– All across Victoria

People involved– Edward Hargraves told everyone about the finding of gold. This is also how the gold rush began. The Government and the diggers were also involved.

Why– Since gold was so valuable at the time and still retains it’s valuable, when people heard about the founding of gold everyone wanted gold for themselves and went to the goldfields to dig for gold.

What– A gold rush is when someone finds gold and then others who hear this information dig for gold themselves.

How did people feel? – Most diggers felt hopeful about the gold rush hoping that they would find gold. However some diggers didn’t find anything or couldn’t dig because gold digging licenses were too expensive. The government took advantage of the gold rush and made gold digging licenses.

What was different at the time? – Mining was much harder at that time because they didn’t have tools such as drills. Mineshaft walls often caved in. A person had to mine with pickaxes and shovels this made mining a risk that could cost your life!

The Consequences– After the gold rush Melbourne became the richest city in the world, and during the gold rush people from all over the world came to mine for gold which made the population of Victoria explode from 70,000 to 500,000!

This is my Description:

Gold Rush Description

The dust blew across my face. I couldn’t keep digging I wiped my brow wiping my sweat onto the open cut blisters that covered my hands. I fell to my knees flinging my pickaxe across the floor. Then in the dim light I heard a wall of gravel fall under my pickaxe. Right before me, a glimmer, an unmistakeable sparkle. I rummaged through the gravel and after the blood, sweat and tears. I’d found it, Edward was right! I rushed to the outside world to tell my brothers. “Aye!” we yelled as we raised our fists. The eight month journey from England paid off, I thought as we cheered.

And this is my Poem:

Gold Rush Poem

I fell to the ground like a withered tree,

Rummaging through the despair for a sparkle of hope,

I waited in my despair…

Then hope found me.
