Phenomena Links

What is A Phenomena?

To be eligible for the prizes an explanation must identify and explain a science phenomena. But what is a phenomena?

Natural phenomena are observable events that occur in the universe and that we can use our science knowledge to explain or predict. The goal of building knowledge in science is to develop general ideas, based on evidence, that can explain and predict phenomena.

Explain your phenomena by answering the question - Why does this happen?

What is A Science Disinformation?

This year we have added a prize for debunking science misinformation. Social media is awash with scientific claims, some valid and some are bogus. Here are some examples (these are all false!):

Of course there are still the classics like vaccines are dangerous and climate change is a hoax and even the earth is flat. Step 1 is to identify the claim. What are they saying is happening? Then research the phenomena and the evidence to see what is really going on. And check out the motivations: Why would they say this? Create a 3 minute video explaining the claim and what the science says.
