Physical Science: How People Get Food
How People Get Food
As the human population grows, more food must be produced to feed a greater number of people. Students will discover some of the ways people produce, process, and distribute food. They will learn of inventions that have solved food problems but have caused new problems that now must be solved; such as taking care of our soil and water. Vocabulary words include: chemical, crops, distribute, grain, hydroponics, irrigate, package, plow, preserve, and tractor.
