Baker’s Half Dozen (31/01/14)
In this regular feature, I list my 6 favourite practical science links from the past fortnight. Only five really got me excited this fortnight! If you have used or seen a great practical resource, let me know by commenting or by tweeting me @TFScientist

- Subject: Biology (Orange Juice Challenge)
- Log in?: No
- Source: Twitter via BioMed Central (@BioMedCentral)
- Author: BioMed Central Blog
- Details: Cheap and easy biology practicals are surprisingly difficult to find. This is a great investigation into how our eyes can fool our taste buds. All you need is some juice, food colouring and the protocol from the bottom of the link.
- Subject: Chemistry (Demonstrations only)
- Log in?: No
- Source: Twitter via National STEM Centre (@NtlSTEMCentre)
- Author: Royal Society of Chemistry
- Details: This is a real chemistry treasure trove! This site contains 100 demonstrations that GCSE pupils are not able to perform themselves. Remember that a demonstration should have a clear purpose, and not be included just to waste a few minutes of lesson time.
- Subject: Practical Science
- Price?: Free (from iTunes or the Apple App store. Not on Android)
- Source/author: Science House Foundation (@sciencehousefdn)
- Details: Over 80 videos of science experiments and demonstrations. A great collection that even shows you how to make your own versions of expensive equipment, for a fraction of the cost. Well worth having on your iPhone or iPad.

- Subject: Biology (DNA Modelling and Replication)
- Log in?: Yes (Free)
- Source and Author: Twitter via Hayley Thompson (@HThompson1982)
- Details:A simple way to model the structure of DNA. Even better, you then use these models to teach DNA replication – the students must figure out how this structure might replicate. A great independent learning idea that is simple and attractive. Perfect! Resource comes with a video, instructions on how to make the model and a fantastic accompanying powerpoint presentation.
- Subject: Science Numeracy
- Log in?: No
- Author: Rob Butler (@cleverfiend)
- Details: Not strictly a practical resource, but a resource useful for practicals. Last Monday, ASEchat (every monday from 8pm!) focussed on numeracy in science. Practical science is a great way of teaching numeracy, particularly with skills such as serial dilutions, graphing, lines of best fit and scaling. Rob provides his take on the chat, with a full transcript available at the bottom of the page
Giving students a say in their homework.
An interesting idea to drum up interest and choice in homework tasks.
“The work of science is to substitute facts for appearances, and demonstrations for impressions.”
(Although nothing makes an impression like a good demonstration!)
