Fall For Fall
This season is the perfect time to see gravity in action. The
gravity created by Earth pulls everything down. Look around and encourage your
little one to explore the evidence of gravity. What objects have fallen from a
higher place? Make a list of everything you find. Can you guess where it came
from and how high? You may come across some acorns, which are very common to
find laying on the ground this time of year. These nuts are an important part
of the food chain for foraging animals. Animals forage and gather food in
preparation for the colder weather ahead. As you forage for gravity’s evidence,
compare your treasures. How many different shapes or colors did you find? Ask
your child what might happen if gravity didn’t exist on Earth. How would it
affect animals that rely on this food source?
Here are some good gravity points to think about:
·
The
gravity from Earth keeps the moon from flying off into space.
·
The
reason objects stay on the Earth’s surface is because of the gravitational pull
towards Earth’s center. If there was no gravity anything not secured to earth
would float away!
·
Gravity
affects how much you weigh. Mars has a lower gravitational pull than Earth, a
person weighing 200 pounds on Earth would only weigh 76 pounds on Mars.
·
The
more mass that an object has, the more gravitational pull it will have, and the
smaller the object’s mass the less gravitational pull it will have.
·
Gravity
guides the growth of plants; stems grow away from the Earth’s center, toward
the sun and roots grow towards the Earth’s center, away from the light.
