27/10/16 THE AMAZING ATOM : Great start on the 27th. Lots of action as we made ourselves into atoms and even a water molecule. Well done to those of you who worked out how many neutrons were in the oxygen atom. Well done to those flighty electrons who found the right orbital shell so quickly. Well done to the person who saw that H2O was two hydrogen atoms and one oxygen atom. Click here to see the notes : The Amazing Atom
3/11/16 : METHOD MATTERS : Some wonderful work by the youngsters tonight. We used the Scientific Method on an investigation into how weight is linked to size. The discussion over the hypothesis was insightful and they worked diligently to collect the data. They were so good, I have written up their work so not only are the visual aids here – but also the results they produced : Method Matters Visuals : Method Matters Results
10/11/16 : MIGHTY MATHS : The aim was to show how plotting data can lead to shapes on a graph which links to an underlying formula which can be used. We drew a large grid on the floor and the children plotted the numbers we gave them onto it. Somewhat chaotic, but they loved it. We had flowers and faces as data points, slightly wobbly lines, and an impromptu pavement art contest after we had finished that produced a lovely cartoon pig and cat and kitten! Mighty Maths
18/11/16 : HOT STUFF 1 : We did convection and conduction today, with the youngsters heating a test tube over a tea-light and watching some seeds rotate up and down in the liquid. We also had some pre-frozen tubes with water and used a wooden stick and metal fork to think about conduction. Youngsters did their experiments very well, guess who was the only one to drop a test tube and break it! Hot Stuff 1
24/11/16 : HOT STUFF 2 : After a recap, we looked at radiation as a method of transferring heat today. The youngsters observed two test tubes filled with boiling water, one clear, one with foil wrapped around it, and plotted the temperatures onto a graph every minute for ten minutes. They all did very well, handling their thermometers carefully so as not to knock over the test tubes, and plotting mostly very accurately. The nice thing about an experiment like this is it teaches multiple issues – what affects the accuracy of measurement, how getting one or two results “wrong” is not a problem, how to handle equipment safely, as well as “what is radiation?” Hot stuff 2
1/12/2016 : HOT STUFF 3 : The youngsters did a tough analysis of their results from the last two weeks today, so to finish we did an observation on magnetism – that the bit that goes before the scientific method (and is included in some versions) and then let them play and get hands on with the magnets in preparation for doing an experiment next week with them. We finished by asking them what they would like to study next week from the effects they observed. Hot Stuff 3
8/12/2016 : MARVELOUS MAGNETISM : For the first time, our youngsters decided for themselves what they would study and how. They asked various questions 1. “How much weight can a magnet hold?”, 2. “How much weight would a magnet repel”, 3. “Which materials are magnetic?” And the answers were :
- Horseshoe magnet : c 300 gm ; skittle magnet : c 600 g ; none of our magnets would hold 1 kilo.
- With 11 rings on the bottom magnet would hold them up by 10 mm; with 20 rings by 7mm; 29 and 31 rings by 3 mm (see picture); 35 rings by 2 mm, so the answer was at least 35 rings = 500 gms
- mild steel, galvanised iron, stainless steel, nickle, chrome
There was a fourth team, who were looking at how many magnets they could stick together and lift a given weight with, but I apologise, I have lost their result!
