How to make Geodes

We have this lovely book all about rocks. A rock is lively by Diana Hutts Aston. It’s all about the ingredients that make up rocks. It has some beautiful pictures in it, in an attempt to recreate some of this beauty we made some Geodes. Geodes are rocks with sparkling crystals inside them.

We made our geodes by slightly heating up some water and dissolving as much salt as possible.

Processed with VSCO with s1 presetWe mixed the salt solution with food colouring inside some egg shells and left them. It took many days for our geodes to develop

The best geodes that we created were the egg shells in pots that started off with the most salt solution in.

Processed with VSCO with s1 presetWe loved how the molecular structure of the salt changed and in some instances created what looked like perfect squares.

When Okido meets Skittles

 I love our Okido Magazine that pops through the door every month. I shouldn’t really say I love it as it’s aimed at 3-8 year olds, but I do! And so does our son (who definitely does fall in correct age bracket).

This months magazine had a fabulous experiment that our children really wanted to try. We got together some skittles, a plate, a bowl and a jug of water.

After arranging the skittles around the upturned bowl, we removed the bowl and poured a small amount of water in the middle of the circle.img_0934We then watched and enjoyed the colour from the skittles dissolving in the water creating this beautiful pattern. It was fun to watch the colours mixing and inevitably turning into a brown mushy colour!

We were interested to see that when we turned over the skittles there were small dots of colour where the skittles were resting on the plate and the water didn’t come into contact with the skittle and therefore the colour didn’t dissolve away.

Nice one OKIDO!

Whats your favourite kids magazine?

 

Look I made a Magnet!

We have a bunch of different magnets in the house but on the whole none that were super powerful. They weren’t strong enough to do the experiments that we wanted to do.

So, we bought some really strong magnets. Now these magnets are definitely not the type to leave around the house for little people to play with at will!! There would be disastorous concequences of non-functioning phones and kurput electrical equipment. So, beware if you decide to do this at home! The packaging was full of strong warnings!

We used these super strong magnets to make…..another magnet!

Little Man stroked a large needle a few times with one side of the magnet and hey presto….the needle became magnetic. The amazing thing was that the magnet stayed magnetic for ages! I though maybe it would be magnetic for a few minutes and we’d have to go through the process again. However, the needle picked up the paper clips and even they became magnetic, I found them sticking to some electrical devise the next day!!

We also used the magnetic needle to create a compass. We laid the needle on some cardboard which we placed in a bowl of water and hey presto. We spun the card around and it would always settle with the needle pointing north! How very cool.

Have you done any magnetic experiments? Did you get the results you imagined?

Floating on Salt

My son said to me today ‘The Dead Sea is as deep as the Eiffel Tower is tall’. He loves watching Go Jetters often shares random facts with me. He went onto tell me ‘The more salt the easier it is for heavy things to float.’ Penguin also loves experiments and suggested we see if things would float in water with salt in, so that’s what we did.

We weren’t very technical about the experiment and didn’t get our coin to float. We just put a lot of salt into a small pot with water. Penguin managed to get a blue bead to float in salty water, even when pushed to the bottom, it still floated back to the surface. The same blue bead sank in regular tap water. He was very excited!

We’ve since found out (after watching YouTube videos of people floating on the Dead Sea) that stuff floats in salty water because the salt makes the water more dense. So our blue bead was less dense than the salty water but more dense than the tap water.

I was really glad this experiment worked and we got the outcome we expected. I’ve been getting tired of trying to do experiments that look good in a science book but in reality don’t work very well.

After watching some videos online we found that this experiment is really effective using an egg. So we had a go 😀

 

Science School – Magic Ice

image

We picked up a new book from the library entitled Science School by Mick Manning and Brita Granstrom. The book is full of science experiments that can be done at home. So here’s our first one…Magic Ice.

Could we get an ice cube out of a glass of water without getting wet?

We were allowed some string and some salt!!

Here’s how we got on. With our ice in the glass, Penguin lay the string on the ice and sprinkled some salt over. We waited for about a minute.

The salt caused the ice to melt a little, the water seeped into the string and the ice caused it to re-freeze and then we could pick up the string and the ice was attached. No wet hands!

Penguin then went in to pick up much more ice with his string. I could tell he was having fun!

Have you done any science experiments at home that worked really well?
