I had a lovely holiday although the weather in Australia has been very wild and woolly so far this year.
To get our brains back into gear and get us thinking, here are the CSIRO Science by Email quiz questions sent to us this week.
1. Which planet in our solar system holds the title for the longest-lived cyclone on record?
2. Do photovoltaics produce direct current or alternating current?
3. What is the defining mineral with the value of 1 on the Mohs hardness scale?
4. What is the term used in biology to describe fish that stay together for social reasons?
5. What marine organism is usually associated with ‘red tides’?
I will post the answers next week.
