Life at Oak Grove

Wondering what boiling water will do at –30C temperature?

Check out this video of instant freezing of boiling water at –30 Celsius.    It works as we did it this morning…

Science project of the day – CHECKED.   Now let’s tackle the rest…

As some of you know already, I review books and products, including homeschool products.

I recently received a fun little thing that contains activities on various subjects.

This morning, I decided to print the activities on frost.  In the middle of these, there was a little experiment.

Take a metal container.

Crush some ice and fill it at about half way.

Include 4 tbsp of salt (we took the salt for canning).

Mix well and wait for a while. 

In the meantime, do another activity like reading to your kids or do some math work…

Once you are done whatever other activity you have decided to do come back to your metal container.

Watch for what happened.

The salt has brought the temperature down on the outside of the can.  

Can you see the frost around ours? 

You can do various sizes to see the difference.

Have fun experimenting with your kids…

A friend recently posted on

facebook

that she was trying Windows Live Writer to help with her post on blogger.

Seeing how this seems to be a success for her, I am trying to experience it as well.

I think I like it.   The ability of using various fonts and other things are quite interesting.  

Let me know what you think…  Here’s a drawing I did last year that I can modidy somewhat to look as an instant picture.   Pretty neat!
