Jan17_Ice1_SM

None of our ice experiments are terribly original. There are a lot of them floating in blogosphere with winter themes, but I am glad that we got to reuse some of those wonderful ideas from The Adventures of Bear and Almost Unschoolers. Anna had a kick first freezing some of small plastic toys that she had and then devising strategies to free them. Her firsJan17_Ice2_SMt idea was to break the ice with a spoon. As she quickly found out, this didn’t quite work. Then we added some food coloring to watch how colors penetrate into ice, and I explained her about salt making ice melt faster. We could observe how the hole in the ice was formed in the place where we added salt. Finally we poured some warm water in the ice to make it melt faster. We also observed that ice floats in water – something that she could link to the movie about polar bears that we watched together.

She immediately wanted to repeat the experiment, but instead we froze colored water to make an experiment on color mixing later this week.

Edited to add: My husband was not pleased at all about salt and ice experiment. I didn't know it before, but apparently you can get a frostbite if ice, salt and water get on your skin if you let the mixture stay for a couple of minutes.

Great ideas. I'd seen some of them around but it's good to have them all in one place for future reference!

I love the mad scientist grin Anna has in the top picture! I looks like she was having really enjoying the experiment.

I'm loving all of these ice experiments I'm seeing everywhere. I'm guessing we'll probably wait until summer when we could use the cooling down here to do ice experiments.
Thanks for linking up again, as always you have cute pictures of your little Anna!

Debbie said...

What great fun! I love how focused Anna is on her science project.

I have to get more science going here.

I love all the different activities you mixed together here!

I never heard that about the frostbite, good to know.

Glad you guys finally got to have some fun with ice!!

As far as the ice and salt giving frostbite, we let ours mix on our skin, myself included, for at least a half hour as we watched, played, waited, kept adding salt and so forth and neither Joe nor I was affected in this way. I'm not saying it couldn't happen, I'm just saying we were fine for the duration of our experiment which was quite lengthy because he enjoyed it so much.

we've done those experiments in my prek class and at home and me or my kids have never gotten frostbite from that.

glad you got around to some science fun

We like to play with ice. We make "icebergs" for the tub - little toys frozen in ice that melt out once in the tub.

We have done the salt experiment and let it sit on our skin without incident.

I have let Emily do a similar experiment making ice caves with blocks of ice and salt water in a spray bottle. I've never heard about frostbite from such experiments...?? Good to know!

Elise said...

I am really enjoying learning about different types of experiments. I have bookmarked similar ideas before, but have not yet done them. I think Savvy would really enjoy working with ice in the ways you did with Anna.

I did not know about the frostbite issue, but will certainly be keeping that in mins when we do this.

We are going to try and make an igloo out of ice cubes using salt to help them stay together. I will have to remember to take breaks to let our fingers warm up.

I saw an activity like this recently, I really want to try this out! I've been really off with my teaching lately. thanks for sharing :)
