Today
is quite cloudy so this experiment might not work so well, but try it on a day
with lots of sunshine!
Some garden flowers follow the sun as
it travels across the summer sky.
Flowers that track the sun are called heliotropic or phototropic flowers.
Heliotropic flowers actually turn
their blossoms to face the sun while phototropic flowers grow toward the
sun.
Many plants with heliotropic flowers
belong to the Sunflower family.
Find a daisy in your garden. it
should be open and facing towards the sun.
Place a container over the flower,
e.g a cup or an empty food tin.
Leave for a while.
When you check back, the daisy should
have closed up.
It thinks it is night-time because it
is dark!!
Let me know if you tried this
experiment!
(a daisy is a great flower to sketch,
examine one closely and try to draw it as accurately as possible)
