The New Scientists playing with food
Two experiments from the New Scientist book ‘How to Fossilise Your Hamster‘.
In the first, we find out how to extract iron from breakfast cereal (perhaps we could use it to make a hammer to deal with the presenter):
In the second, we see how to extract casein (as an example of a polymer) from milk, using just vinegar and a stove. They keep saying ‘plastic’ here, but I’m pretty sure it’s not a plastic. Plastics are polymers, but casein is a protein (though still a polymer). Correct me if I’m wrong. Either way, it might be a good trick to introduce the proteins topics in DP Bio.
DNA Extraction: a simple method and a music video
A simple DNA extraction worksheet is posted in the BOX on the right.
Alternatively, go here.
This video shows a guy extracting pea DNA and using it to draw a portrait of Darwin.
(Music Yeah Yeah Yeahs – Tick)
5,000 views and another Brainiac post
Thanks for the support.
Here are the Brainiacs looking at the differences between fat and thin people.
In these two clips, we can see the buoyant and thermal properties of lipids – ideal for the IBDP Bio statement on the properties of lipids.
Hip-Hip-Hooray for DNA
I don’t know how sincere this is – it sounds like it might’ve been heavily influenced by Monty Python – but it’s catchy and I like it. Peter Weatherall has a few if these on YouTube, so go and have a look.
Another catchy one (this time about photosynthesis) after the jump.
New Scientist Vodcasts
Vodcast? It’s like a podcast, but with video – hence the ‘Vod’.
NewScientist.com have their own channel on YouTube (which I just discovered) and a weekly roundup on Fridays.
A couple of minutes of Science news – with pictures – on Fridays?
Sounds like a good idea for those review lessons.
To get us started, here’s this week’s episode:
Some Cell Cycle Silliness
Very silly – but could be used to lighten a dull lesson or start a discussion on what’s missing. Thanks to greathat from the TES Boards for posting the links.
1. Mitosis Song with hi-tech video:
“Please baby, no television – I just wanna talk about cell division…”
Two meiosis videos after the jump.
Screaming Jellybaby
There are loads of these on the internet.
In this one, a bunch of halfwits fire bits of the reaction all over the show.
The Why’s Guy – a great resource of Chemistry and Physics clips
This one’s been a team effort, so thanks. Specko from the TES Boards pointed me in the direction of this site, which is an archive of clips from a show called the Morning Show in the States. Each week, Mats Selens does an experiment or two and explains what’s going on. Nice, short, simple, well-explained – just the way we like it. I contacted Mats (the one with the beard) and he gave me permission to put a clip on this blog, so please go and investigate his site. For each episode, you can download a .wmv file which is of much better quality than these YouTube compressions.
In these two sample clips, Mats is explaining electrolysis of water and discussing the use of fuel cells and hydrogen as a power source.
Part two after the jump.
2000 Views and a Brainiac post
Thanks for the support so far – this blog’s only been going six weeks and it feels like it’s coming along nicely.
Love ’em or loathe ’em, Brainiac is a decent way to engage the telly-addicted, so I thought I’d put up one of their clips. Here is the Brainiac way of doing the thermite reaction:
Mybusters: Diet Coke and Mentos
I like Mythbusters – especially when some helpful soul cuts the experiments together into single clips, rather than having to flick through a whole episode. Thanks to dannynic from the TES Boards for this link.
I’ll get some more Mythbusters and Brainiac clips up soon – snowed under with student-led conferences at the moment.
