pulleys help us? Use this simple activity to help your child find out.
Have your child fill
a sand bucket with blocks and try to lift it. Ask your child if the bucket
is heavy or light.
Tie one end of the rope to the sand bucket handle and drape the other end
over a doorknob.
Then let your child pull the loose end of the rope to lift the bucket.
Your child will discover
that using the rope makes lifting the bucket easier. Explain that a
simple machine called a
"pulley" operates in the same way as pulling the rope over the doorknob.
Point out that cranes have pulleys that allow them to lift heavy objects

machines in the different centers. I use a pulley
system connecting the writing center and mailboxes.
The kids can pull the rope and deliver the mail.
Hard Hat Hide - n - Seek
In advance, collect
three plastic hard hats (without the inside padding and straps) and an
assortment of metal hardware items, such as hinges and large washers.
Set these items
in a center along with a roll of masking tape and a strong bar magnet.
Invite children to
visit this center in pairs. To do this activity, instruct one child
to tape a piece of hardware
inside the top of one of the hats. Then have him mix up the hats and
arrange them in a row.
Next, ask his partner to guess which hat contains the hardware.
Have the partner use the
magnet to check her guess. What an exciting discovery when one of
the hats responds to
the magnet by moving. Have the partners switch roles and repeat the
activity as often as desired.
