Apologies in advance for the rather self-indulgent post but…
…Snapshot Science is now a year old! I am actually rather proud of the fact that I have managed to keep on blogging for a whole year. Since the birth of Snapshot Science I have posted 78 times and uploaded 41 teaching resources (see the menu at the top of the page to view them).Here I would like to take some time to highlight some older posts that I enjoyed writing but which may have been overlooked:
10th May 2010 – Brown rat tops the charts
This post discusses why the brown rat received the title of the most invasive species in Europe. The resource that accompanies the post contains a group activity which would be a great addition to any unit on ecosystems. It includes information on many different invasive species and asks the students to discuss in groups which one they think is the most invasive using a set of criteria. In doing this they learn about what invasive species are, how they affect food webs and if think we should actively be controlling their numbers.
20th May 2010 – Mobile phones – should we be worried?
This is a science skills post looking at analysing evidence. The accompanying resource contains details about a study carried out to see if using mobile phones increases the risk of developing brain cancer. Students analyse the results to see why the media were able to interpret the results to give so many different headlines.
13th September 2010 – Hot news for chilli heads
I am a bit of a chilli fanatic so was rather proud to read that Britain is home to the world’s hottest chilli – the infinity chilli. Incorporating this into a science lesson proved tricky until I looked into the cause of a chilli’s fieriness – a chemical called capsaicin. The hotness of a chilli is rated in Scovilles and is calculated by measuring the concentration of capsaicin. The resource I uploaded asks KS4/5 students to work out the RMM of capsaicin and then contains an activity where they are told the molarity of the infinity chilli and use the moles formulae to calculate its Scoville units.
Thank you to all those who have visited, subscribed, commented and tweeted. For all of you who are bloggers you know that feedback is what motivates you to keep on writing (unless you are making money out of your ventures which I am not!) So if you would like to see another year’s worth of lesson ideas and resources please take time out to add a comment or drop me a line using my feedback form. It will be really appreciated.
