=Ecosystems=
Ecosystem is a big buzz-word. Find out what all those buzzers are talking about with this BrainPOP movie on ecosystems! In it, Tim and Moby explain what an ecosystem is and what makes one up. For instance, you’ll learn what communities, populations, and habitats are, and why animals tend to be well-adapted to their environment — like desert species being well-adapted to hot, dry, conditions, while species living in the taiga are well-adapted to the cold. Come on and be an ecosystem expert!

The three questions; copy and paste onto google docs

What is an ecosystem?

How do people change ecosystems?

How do animals adapt to live in different ecosystems?



Task 2: Research and discuss the advantages, disadvantages (ethical concern) and limitations of zoo as a place for animal research, reproduction, protection and tourism.

My son tried his very best to get the parts of gundam he wanted by nipping using a nipper/plier. He couldn't. Suggest what he can do or what must be done so he can nip successfully.

Model Answer:
He should either increase PD or E. Reason: Torque = perpendicular distance between effort and fulcrum (PD) x effort (E). If either PD and E is increased, torque will increase.

Diffusion:

http://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter2/animation__how_diffusion_works.html


Notes:

  • All matter is made of particles
  • 'Particle' can mean an atom or a group of atom
  • In a solid: the particles vibrate on the spot, they are held together by strong forces, and are closely packed in a regular pattern
  • In a liquid: the particles move about and slide over each other, they are held by weaker forces, and are closely packed but not in a regular pattern
  • In a gas: the particles are moving quickly. There are no forces holding the particles together. They are far apart in no regular pattern
  • Particles vibrate more at higher temperatures
  • Solids and liquids have greater density than gases
  • Solids and liquids expand because the particles vibrate more when they are heated
  • Diffusion is spreading and mixing caused by the movement of particles
  • Diffusion happens in gases and liquids
  • Gases cause gas pressure
  • Gas pressure is because of the gas particles hitting a surface





Lesson 4:

SCIENCE 2011 - 2012:


Summative practical task

Investigate whether caffeine affects reaction time.

In this task, you have to design a suitable method to measure reaction time. You can no longer use the ruler drop experiment's method.

This task assesses criteria D and E.

For criterion D, you will plan the experiment from the aim to the method and write the evaluation after the experiment is completed.
For criterion E, you will collect data using appropriate tables and process data into appropriate graphs. Use Apple Numbers and it's processing functions as we have done for the ruler drop experiment. After processing data, write conclusion using the format described in the SOR.

6A - 16th May:
Today, we have completed two experiments:
1) From the onion experiment, we may be able to investigate if chemicals from onion can speed up our nervous system reaction.
2) From the 'effect of caffeine on ruler drop experiment', we can compare the data from earlier experiment and today's data to investigate if caffeine speeds up physical reaction.
You are expected to use Numbers application, the formula, tabling and graphing functions, to process the data. This task would assess criterion E Data Processing. So, I'm looking forward to see a report (Data Collection, Data Processing, Conclusion and Evaluation) that are packed with organized data, illustrated graphs, critical analysis and evaluation.

Essay:
The disadvantages of global warming are higher sea level which leads to floods, disasters and such. The deserts would get drier because of the warmer whether, and there would be draughts and water shortage. The heat waves can cause people to stay indoors, causing more electricity to be used for air conditioners. Food shortages can lead starvation and death, and the loss of polar ice caps would be permanent. Also, in a economical view, increased immigrants from poorer countries to a wealthier or a better country for jobs, shelter or foods could cause the poor country to be in a worse situation where the community is not going on fluently.

Comment:
how do we know that these are happening? What is the evidence? How do we support this?

Essay:
The negative effects of global warming would be the melt of the polar ice caps, leading the sea levels to rise around the low lying regions, causing floods and evacuation. This can cause the farmers won’t be able to get food from their farms, and lead food shortages and death. Because of the heat, the deserts would get drier and there would be water shortages and loss of natural habitats. The immigrants from poor countries to a wealthier county would cause the poor countries’ community to worsen.

Comment:
leading the sea levels to rise around the low lying regions, causing floods and evacuation. - are there evidences showing that these are happening?
Because of the heat, the deserts would get drier and there would be water shortages and loss of natural habitats - incomplete ideas; why would heat dry up deserts? Isn't deserts already dry?

The immigrants from poor countries to a wealthier county would cause the poor countries’ community to worsen. - describe and discuss

"How science and technology have enabled us to adapt better to our environment and become more competitive?"

  • Example of appropriate topic: How humans have learnt to harvest solar energy as renewable energy
  • Why is it appropriate? Renewable energy is enabling us to adapt better to our environment by depending less on fossil energy.

Task:

Write and present an essay on "How science and technology have enabled us to adapt better to our environment and become more competitive?"

Rubrics for the task above :

MULTIMEDIA PRESENTATION CHECKLIST :

What's the difference between stating, describing and explaining?
  • Smoking affects sports performance - stating - 1 to 2
  • Tar from cigarette stays in the lungs - describing - 3 to 4
  • Healthy lungs may have about 100% surface available for exchanges of air. The lungs are responsible for taking in oxygen and taking out carbon dioxide. Tar from smoking stays on the surface of lung and prevent exchanges of gases. The tar can also destroy the lung cells rendering it useless. Smokers have less surface area available for exchanging air, and gets tired more easily because there are less oxygen available. An athlete who stays smoke free is more competitive than another who smokes, because he has that extra energy from the same sports activity. He has more surface area for respiration and respiration is important for producing energy. - explaining - 5 to 6

DEADLINE - Science essay is due Monday 19 April and the Multimedia Presentation is due Thursday 22 April

  4. How has this experiment helped you to better understand the concept of adaptation (how organisms react to environment and changes to environment?

Guidance:
  1. Read the rubrics for the criteria.
  2. Familiarize with the science language being used for investigations. e.g. control variable, independent variable, hypothesis, adaptation, measurement.

Criteria being assessed - criteria B (communication) and C (knowledge and understanding)



Personal Project: Science Concept Video

Duration: 2 months

Can you demonstrate a science concept, through a video clip, in 60 seconds? TIS is participating in a Australian Science Competition, called 60 seconds science (http://www.60secondscience. net/). Choose your favorite science concept and think of an experiment or demonstration that can illustrate the concept. You will be planning, directing, writing, filming and editing your first professional science video! It's very exciting and there are prizes and acknowledgement for the winners! Criteria B,C,D,E and F will be used to assess this project and this project is a major task!


Science Investigation: What affects the behaviour of organisms?


1. Download and complete all nine planning questions.

2. Tentative project end date: 2nd week of March

3. Criteria to assess: B, C, D, E, F

4. Guidance:
a) Write and update the report as the experiment progresses. Don't wait to the end.
b) Share data with your partner as soon as it is available, so you will not be affected if your partner is absent.
c) Read up on adaptation and meal worms. The more you know and understand, the better the report will be, so that your hypothesis and discussions will be factual and conceptual.
d) Read on a grade 10 report assessed as a 6 for criteria B, D and E - . Note how citations are written.

e) Teacher's note and comment - READ
