Weather is part of our Today Board but instead of just working on current conditions we are working on weather concepts using Simple Weather Experiments With Everyday Materials as our guide I figure by the time we get through the book there will some real Utah snow and avalanche forecasts to play around with.
[Length vs. Height, Pp24.]
What you need is a flashlight or a movable light source, a pencil standing upright in the center of a spool of thread. (The book has more instructions for measuring shadow length).
When the light is at a slant the shadows are long.
When the light is high above the pencil the shadow is short.
Any science play that gets you standing on the kitchen table is good stuff!!!
