When I am older I would like to be a scientist. At the weekend me and Daddy did some science this is what we did.
It was called chromatography we were trying to find out what colours were in my black pen. It was fun because it was interesting to see what would happen to the ink also because I liked guessing what would happen. I like science I can do on my own (but I still love doing it with DADDY)
Me and Daddy have done more science like when we did an experiment with two balloons, a candle and some matches. First we blew up a balloon, and lit fire to the candle and put it under the balloon. Then it went kaboom! After that we put water in a balloon, and put the candle under it. And it didn’t go kaboom. Instead, there was a big black mark on the bottom. Daddy rubbed his finger on it and some of it came off!
Me and Daddy have done lots of experiments, like separating milk into curds and whey. We used vinegar to separate it. I didn’t get to taste it though. But it looked pretty weird.
I have a science game in my room called an electronics set, which you build parts of it and you get a light or a sound or a funny noise but you can also get a fan. It goes a little crazy if you leave it on for too long, it flies off the top which is very funny.
We made our own battery before out of vinegar and bits of metal.
Next week is my half term so if you have any ideas for me to do please could you tell me. Thank you.
What Grace Did... 
Hey, nice science post. I can recommend making a pop pop boat: http://www.sciencetoymaker.org/boat/index.htm you just need a can of coke, 2 straws, some glue, a tea light and something that floats. I made one a while ago and really enjoyed it.
Thank you.I will try that. After I have tried that I will tell you on my blog.

How about making a balloon inflator – http://www.sciencebob.com/experiments/fizzinflator.php
We’ve tried something a bit similar to that idea but we can still try it. Thank you for that idea.

Very good! Chromatography is great fun – really surprising how different pens are that seem to be the same ‘colour’. And it’s something that is really used a lot. Somewhere I still have two Usbourne Books with Chemistry and Electronics Experiments you can do. See if I can find them out! The chemisty one showed you how to do exactly what you’ve done – but to work out if a cheque (ask your Daddy what they are – you don’t see them very often now) was modified by some crook. The crook would most likely use a different pen from the original author so with Chromatography you could tell!
But here’s any idea I thought of… can’t do it with my son yet as he’s not quite old enough…
The Screen Wash detergent that goes into cars to clean the windscreen have on the back what different concentrations to use… so in summer use a lot of water and little screen wash. Winter use about half and half… severe winter use just screen wash. Idea being that Screen Wash freezes at a lower temperature than just water.
Problem is what does ‘winter’ actually mean? So if you do have half and half water and screen wash at what temperature will it actually freeze? Last week it’s got to about -4C over night… so based on your experiments what ratio (how much screen wash how much water) do I need?
Would be really useful if you could work that out 🙂
Enjoy!!
Thank you it sounds lots of fun I will try that and tell you.

Hey Grace,
Great science! Some fun things you could do next week, hmm…
How about some investigations? You could take some bulbs (daffodil perhaps) and see what affects how they grow. Would it grow it you planted it upside down? If you left it in the dark? In the fridge? In a pot on the window sill? You make a prediction about what you think will happen then check on them every day and note your observations. You can then look back and see if your guess was right or if something unexpected happened.
Or perhaps something more explosive… what about building your own fizzy drink bottle rocket? (ask the neighbours first!) Or a homemade volacno? You can make it out of paper mache, paint it and then create your own lava with vinegar and bicarbonate of soda. Both of these would make a cool film.
I hope you find some fun things to do and I’ll be interested to see what you find out.
Kat (your mum’s friend)
Wow that sounds amazing. I will definitely see if I can try it. I’ll ask Daddy. Thank you.

Hi Grace, my son who is 11 likes science too. We have grown a copper sulphate crystal which was cool, but you have to be patient while it grows. Get your Daddy to help you. Have fun 🙂
Thank you very much. I have seen that once on Mummy’s computer and I said can I have a go at that. So I will definitely have a go.
