The resource covers basic logic and faulty arguments, developing student's critical thinking skills.

Suitable for year 8-10, focused on science issues, the module can be adapted to suit classroom plans.

The resource is found here:

There are also two new downloadable Critical Thinking guides:
A postcard-sized one: http://technyou.edu.au/wp-content/upl...
and
An extended version for secondary school teachers: http://technyou.edu.au/wp-content/upl...

Good series, although too short.

Second season gets into the scientific process - link at the end of this video :)

There are rampant misunderstandings with regard to scientific laws, theories and facts. Laws are consistent observable scientific facts under particular conditions. Theories explain how certain facts occur. For example: The Law of Gravity would state that, depending on distance, an apple would tend to fall toward the Earth. The theory of gravity would explain how this happens. In Evolution. Evolution is a fact and a theory. Evolution occurs, FACT. How this occurs is a where the theory comes in.

Thanks Francisco - what if we made more? :)

Well you're in for a treat tonight :)

Subscribed, saw it super early ;)

Guess what? New season has started :)

The precautionary principle is used throughout all forms of engineering; it's just not called "the precautionary principle." In aeronautical engineering they use triple redundancy in critical systems. This idea was applied to the braking systems in cars. To design a bridge beam, engineers calculate the strength required to withstand the absolute worst case and then add 40% more strength. This is called "the engineering factor. The PP is SOP in engineering because it works best.

PLS DO

No, there isn't such thing, In science "law" and "theory" means exactly the same. Choosing one or another is just rhetorical.
