Developing the capabilities to interact with science (24.08.15)

Developing the capabilities to interact with 

science

Paul Ashman






Nature of Science Capabilities
-          Gather and interpret data
-          Use evidence
-          Critique evidence
-          Interpret representations
-          Engage with science

When does a simple task become science?
-          Investigating
-          Questioning
-          Evaluating
-          Reasoning
-          Thinking
-          Curiosity
-          Wondering
-          Observations
-          Making connections

Nature of Science
-          Observe scientists
-          Science of self
-          Science is constantly being re-evaluated in light of new evidence
-          How to carry out a scientific investigation
-          Understanding how science works
-          Make connections between science knowledge and everyday decisions and actions
-          This is a compulsory strand – the other strands provide context for learning
-          Assessment should be based on the nature of science understanding (capabilities)


The difference between observations and inferences



-          Weta
o    That is an inference
o    What If there was an insect that looked just like a weta?
o    Prove it
o    What can you see about them
o    Insect = 6 legs
o    Link observations to what you think
- I see long spindly legs coming out the front, I think they are antennae

-          Bird
o    I can see claws with webbing that I think is its foot
o    Feathers

-          Grass, leaves, green vegetation

Things we can’t tell but that we infer:
-          If the bird is dead
-          If the weta are eating the bird
-          That this is a bird
-          Where the photo takes place 

What can we see?



-          Circles
-          Spikes
-          Perception varies – are the circles at the back in or out
-          Wonderings – If this is an eyeball then how do they blink? Why does it have so many bits?
-          As soon as students know what it is, they will stop thinking
-          Try and find images that don’t give away what ‘it’ is

Observations                                                                                                                                              

                                                     

Lit candle (What can you see, what do you notice)
Record = draw or write
Observation types – visual, tactile sense, what isn’t happening, changes
-          Noticing = engaged other senses
-          Feel the heat
-          The closer my hand got to the flame the hotter it got
-          Yellow and orange at the top
-          Blue flame at the base
-          End of the wick glows with an orange ember
-          There is an aura around the flame, it looks like a lighter flame
-          Some of the candle is melting
-          The wick is charred black where the flame is touching
-          Wick has woven pattern
-          The wick has a hook shape
-          The flame has different tones
-          The flame changes height – why?
-          Hotter above the flame than the sides
-          Wax doesn’t catch burn
-          Rapid air movement causes the candle to smoke
-          Air movement – concave/convex shape flame

Progress:
-          What do students notice?
o    Things
o    Attribute
o    Change
-          What senses do they use?
-          What language do they use?
o    Descriptive language
o    Topic specific words
o    Scientific words


Do students make inferences without attempting to explain why they think something?
-          “I think it’s hot”
Do they make an inference and attempt to explain their thinking?
-          “I think it might get a little air in it so it lightens up a little bit”
What links do they make?
-          To previous experience?
-          To scientific ideas?

Notice > Think > Wonder > Predict > Observe > Explain

-          I see/I notice
-          I think
-          I wonder

I notice = engaging more of the senses
-          I notice with my hand
-          I notice with my nose

Get students to justify what they are seeing and justify what they think

Informed Questions
-          Is there evidence backing up this claim?
-          Is the argument logical?
-          Was the testing robust?
-          Are the findings represented in a fair way?



What information can we get from this?
-          By doing this we are starting to critique it
o    Lot of rats
o    Both graphs have rats and birds
o    How many cats were interviewed?
o    What was the time frame for the data collection?
o    What time of day is the data collected?
o    Is this in a rural or town setting?

Critiquing Evidence
Design an experiment to test which tissue is stronger.



Representing Ideas
-          Farming and global warming
-          Comparing pictures
-          Reading graphs, tables etc…
-          Using scientific language

Resources
-          Making better sense books
-          Building science concept books
-          The arbs
-          Connected journals
-          TKI

TKI Website
-          Introducing science capabilities
o    Information about each
o    Resources that link directly into the capabilities
   -  Resources broken up into levels
