This was a bit of a "trick your body" experiment, but it also shows how the body's thermometer is more of a relative gauge of temperature, ie if you walked into a room from outside in the freezing cold it would feel warm, but if you came into the same room after having a warm shower the same room would feel cold.

Temperature experiments
It was great doing a few mini experiments this week, and the girls performed a few more at their Brownies meeting for the Science Investigator badge. It reminded me how much children love experiments, and I must really incorporate more in.
This was a bit of a "trick your body" experiment, but it also shows how the body's thermometer is more of a relative gauge of temperature, ie if you walked into a room from outside in the freezing cold it would feel warm, but if you came into the same room after having a warm shower the same room would feel cold.
Arrange three bowls of water, one with very warm water, one with very cold water and one with room temp water. Put one hand in the cold water and one hand in the warm water. Hold it there a minute. Put both hands in the room temp water, and your two hands will send you very mixed messages on the temperature.
Ciara getting in there too.
The next was creating a mini watercycle. Place room temp water in a jar, place cling film on the top and top of with ice(we used an icepack). Place water near a heat source(signifying the sun), which will cause the water to turn into water vapour. This water vapour will come into contact with the ice(cool air high in the sky) and turn to droplets(like the clouds), after a while the droplets become heavy enough to drop back down again like the rain.

Some stained glass techniques
We have been doing our Jesse tree readings leading up to Christmas. Yesterday Jude made a stained glass effect earth for our reading on creation, and today they all got stuck into making a stained glass snake for our reading on the fall.
Stained Glass effect Snake.
First add black acrylic paint to pva glue and give it a good mix until everything turns black.
Outline a picture of a snake (use watercolour paper, or thick paper).
Leave the outline to dry.
Paint in with watercolour paints, it turned out so well that everyone wanted to do one.
Jude coloured in this earth and then dipped cottonwool in oil and covered the picture with it.
We then put it on the window to let the light shine in.
I was so pleased that Ciara wrote this so well, she must be quite familiar with the shapes of the letters in her mind to be able to copy my dots so closely.

A nice reward
Eden finished her final test for her Delta maths course today. She has a fantastic grasp of multiplication and division now, and can do more complicated long division than I ever needed to do by hand. She can also write and read Roman Numerals far more proficiently than I ever have, more fun than useful, and she can work out areas on a few different geometrical shapes. She knew I was going to give her a special gift for finishing this, and did 6 pages in one day yesterday, but I insisted she finish the test today, before she got her reward, and I am glad she did, it was a great confidence booster to her to see she got a distinction in the test.
The reward is something she has been asking for for a long time, a quill and ink set.
She tested it out straight away, and will now be able to learn some calligraphy.
