Here are some of my favourite fun songs about science.
ASAP Science is a great site. Here is their song about the whole periodic table of the elements, in order: ASAP element song.
Here is Tom Lehrer’s original element song: The Elements.
Here is a song about ionic and covalent bonding: The Bonding Song
And here is Veritasium’s song about Chemical Bonding
Here is a bonding version of the Lazy Song – it’s really out of tune but the song is good!
Here is one we wrote for the song ‘Happy’: Happy bonding song
At school we do science but it’s all about plants. This is biology. But if you take biology and just look at it much more close up, you end up with chemistry. And if you go even more close up you end up with physics.
This is the kind of science I enjoy and I am trying to find out about at the moment: all the little particles and the spaces between them, and how they act around each other. So if you know about this sort of thing and you’d like to tell me some cool stuff, you can leave a comment! Thanks.
I made this with my geomags.
It’s actually just a normal icosahedron, but with triangular prisms on all the surfaces.
In my mind this is a science space station, and each of the triangular prisms is a separate lab.
If something goes wrong with an experiment and is going to make the lab explode, the whole lab can be ejected into space.
I got an energy cosmic ball as a present (it’s got two electrodes on it so that when you touch them both it completes the circuit and makes it light up and make an alarm noise). I also have a plasma ball. When I put them next to each other the energy ball made strange noises – and the noise changed when I moved it around (one note for one of the electrodes, and a different note for the other one, and when I made them touch it made an angry noise). BUT WHY? I know that if you hold a light bulb near a plasma ball it lights up, but why did it make the energy ball make strange noises not just its normal noise?
I have a new project: I want to collect all of the elements, but starting with the ones that are not dangerous, and that I can buy for not very much money or that I can find in the ground or in ordinary things that nobody wants.
If you know what any of the elements are and where I can find them, please can you tell me by writing a comment?
I got the idea from Itch, which is a book by Simon Mayo. You can buy it here, it’s really good and very exciting as well as being about science.
You can see how far I have got here.
My last birthday cake was pretty cool – it spells my name in morse code using maltesers and chocolate fingers.
When I was six my cake was a chocolate cake with the middle bit cut out and white icing in the shape of a dinosaur skeleton, then with the cake crumbs put back on top of it. We dug up the bones with spoons! We can’t find the photo of that one, though.
I found this site that shows you how to make a cake that looks like Jupiter – even when you cut into it!
In the Pathology Department I made pathogens out of sweeties. The marshmallow with the shoelaces is salmonella and the other two are parasitic worms. You can see their faces.
We learned a dance that showed how haemoglobin gets oxygen from the lungs and takes it to the muscles.
In the Chemistry Department I played in the non-Newtonian slime, then extracted the DNA from a strawberry using washing up liquid, pineapple juice, ethanol and a tea strainer. The white goo in the last two pictures is the DNA.
Then we watched them make ice cream using liquid nitrogen. It was really tasty! I won a prize for the chemical elements quiz, played with Teflon-coated magic sand, and built a model hydrogen molecule.
In the Pharmacology Department I looked at water fleas through a microscope and we counted their heartbeats then gave them red bull to drink to see if their hearts would beat faster and then alcohol to see if it would beat slower. They let us catch one of them with a pipette, and take it home as a pet.
In the Psychology Department I was in an experiment about illusions and tried experiments about gambling and about how people make decisions.
Finally, we went to a pretend crime scene and did forensic science.
It was a really amazing day!
Today we tested lots of things to see if they were acidic or alkaline. Here are our results:
The most alkaline thing we found was flash kitchen spray and drain unblocker. These have bleach in them, so we were really careful.
The most acidic things we found were wine and fruit juice.
Acidic things make the testing paper go orange or red, and alkaline things make the paper go green or blue or even purple!
I let mummy have some of my iron powder from my chemistry set for the Christingle service so that we could sprinkle it on the candles to make mini fireworks! It was cool. I wore my goggles and gloves as I held the candle for her, just in case. Dr Bunhead did the same thing but with a blow torch, which made a much bigger sparkle! But we didn’t have a blow torch…
What was really interesting is that we used a telescopic magnet to pick up the iron powder and keep it all together, but when we stuck that in the candle flame there wasn’t any sparkle – the magnet stopped the powder from escaping and it can’t sparkle if it can’t escape!
The magnet was really useful for collecting all the powder that got spilled. We couldn’t get the powder off it very easily, so we put the magnet in a petri dish and then put another, stronger magnet underneath the dish to get all the powder to peel off and end up just sitting in the petri dish.
This is a science experiment that I did when I was four, but I didn’t have a blog then so it went on my mum’s blog and we only just thought of moving it here to my blog.
We have a rug in the bedroom that seems to walk across the floor while we are not looking. We know it does this, and now we are fairly sure we know how.
So, here’s the experiment, which I mostly thought of all by myself:
My mum has two 5kg weights and we put them at one end of the rug to weight it down, and we used stickers on the carpet to mark the rug’s starting position. We marked the new position of the rug first thing in the morning every day, to see whether the rug still walks in a straight line, or whether the weights stop one end from moving so that it starts to move in a circle, with the weighted end staying still.
What happened was that the first day the rug moved around a bit of a circle, with the weight end staying still, and the next day it moved again, but a bit less, and then the third day, less still. What we think is that it’s the direction of the carpet pile (the way the carpet is hairy) that makes it move, so it can’t go round in a whole circle, it really wants to go straight but it can’t because of the weights. We think when you tread on the rug it squashes the pile of the carpet and then when the pile goes up again it has moved the rug just a tiny bit. So if you didn’t walk on the rug it wouldn’t move.
This was a very cool experiment!
