Humans and bugs both have legs, brains, and the use of gravity to help make walking easier. The body uses energy when lifting the leg up and forward during walking. The immediate action of putting your foot down is a result of gravity doing the work. The strongest insect in the world is called the rhinoceros beetle. It can carry up to 800 times its body weight on six skinny legs.
Cockroaches are arthropods, which means they have jointed limbs.
See how jointed limbs and muscles attached to a strong skeleton allow these insects to move very quickly. Resisting Gravity Begin the experiment by asking students to define gravity. Using these materials, design a parachute for a paper clip. Next, hold a plain paper clip in one hand, and a paper clip with a parachute attached in the other hand. Drop both paper clips at the same time from the same height.
