Homeschool pine cone science experiment
PINE CONE SCIENCE EXPERIMENT Vol 1
Why do pine cones open and close?
Someone was very impatient to see the result:)
PINE CONE SCIENCE EXPERIMENT Vol 2
Which one will close faster?
The one in the hot water or the one in the cold water?
Before finding the answer to this question,this little lady observed that pine cones float.As long as nobody touches them of course:)
PINE CONE SCIENCE EXPERIMENT Vol 3
This little lady discovered that pine cones close up when they get wet.
She also observed that the pine cone in the hot water closed faster than the one in the cold water.
Honestly speaking,I had thought that the one in the cold water would close faster (as I had read so on Pinterest),but the result was just the opposite.
