Fun with frozen: making ice grow

I have been noticing lots of fun ideas being shared by my fellow bloggers that are all related to the Walt Disney movie “Frozen.”  I must admit that my grandsons and I have enjoyed watching this movie at home on more that one occasion. So for all you “Frozen” fans out there (and for those of you who just like really cool ice science), here is a fun way to make ice grow just like Elsa does! Well almost – to correctly state this for our young scientists, here is what crystallization means…

So I am going to try and explain this but at the end of this post, I will put a video link to where you can learn a little bit more about it and probably understand it better too.  It isn’t all that complicated but it helps to have a little extra information.  First you need to place some unopened bottles of water in your freezer and leave them there for about 2 hours and 45 minutes…

You can color the water first if you would like to make colored ice grow. I tried it both ways with the same success. Be sure to seal the bottle closed tightly before placing them in your freezer. Set your bottles flat in the freezer like I have here for best results…

After the 2 hours and 45 minutes, your water should still look like water and not be frozen. The photo below is too frozen…

Gently take your super icy cold water out of the freezer and handle very gently. Don’t shake, knock, or jar the bottle or your water will now turn into ice before you are ready.  Set out a tub of ice (you need to use a container that will allow for plenty of water overflow so a bigger container might be better than the cup you see here).  Then pour a steady stream of water over the ice and you will see the ice begin to grow. You can do this on one ice cube or a bunch of ice cubes…

Keep the stream of water going. Move it around a bit as your ice grows taller and grow more ice around your container. You can create as many ice towers (or castles) as you like until your bottle runs out of water or your container starts to get too full and spill out onto the floor! By keeping the water pouring in one spot, your ice will grow…

and grow…

I haven’t tried this with my class yet but it is on my list to do. First we will work on our pouring skills through water play and then we will be ready to give this idea a go! I’ve added a short video of the process  which you can view below…

Now to learn more about this entire process, you will want to view this video below or it can be found here —>

    Awesome! I already had my two week summer preschool camp with ‘Frozen’ as one of the themes, but this is cool in general. Thanks!

    Hi I have just been introduced to your Live caterpiller kit and was interested where are you based, I am in Victoria Austraila andwas wondering if you deliver here (before the eggs hatch)

      Hi Janette,
      I am sorry if I have confused you but I do not sell the caterpillar kits. I was given one by a parent but you can possibly go on Amazon and order one. I am not sure where they would be available to folks in Australia! My best to you! Deborah
