While building a soapbox racing car, a pair of friends provide an
easy-to-understand lesson in how simple machines are all around us,
making our work more efficient. Michael and Luci show readers that a
broom is a lever, nails are wedges, and a screwdriver is both a lever
and a wheel and axle. The two also prove that curious children can be
just like scientists, making observations and using how and what
questions to explore physical science principles they encounter all the
time. Michael's Racing Machine is part of the I Wonder Why book
series, written to ignite the curiosity of children in grades K-6 while
encouraging them to become avid readers. These books explore the marvels
of light, color, machines, sound, and other phenomena related to
physical science. Included in each volume is a Parent/Teacher Handbook
with coordinating activities. The I Wonder Why series is written by an
award-winning science educator and published by NSTA Kids, a division of
NSTA Press.
