Frost Under a Finger
On the first frosty morning every blade of grass has grown white needles. A warm fingertip melts a dark print into them, and your child starts hunting for the coldest corner of the yard.
What you need
- A frosty morning
- Gloves you can take off for a second
- The yard, a fence and some fallen leaves
How to play
- Go out on the first frosty morning, before the sun reaches the yard.
- Look for frost on grass blades, on a fence rail and on fallen leaves.
- Press a warm fingertip onto the frost and count how long the dark print stays.
- Breathe on a frosted leaf and watch the white pattern vanish.
- Find the corner of the yard where the frost is thickest and decide why.
- Come back at midday and see which side of the fence still has frost on it.
