Read. Look and point to
three objects in the park
that people made.
Different Materials
People use materials to make objects. Some materials are
natural. Natural means not made by people. Materials that
come directly from Earth are natural. Wood and cotton are
natural. Rocks and minerals are natural, too. Sometimes
people use natural
materials to make
new materials.
Plastic is a material
