LESSON PROBLEM: What does the rice farmer use to get the rice to the mill?


The rice farmer uses many machines to get rice from the farm to the market. There are tractors, trucks and combines.

Tractors get the field ready for planting. Combines are used to harvest the rice.

Trucks carry the rice from the field to the rice mill. The truck carries heavy loads of rice.

Many trucks are used to carry the rice to the mill.

The rice is cleaned at the mill. Once it is cleaned the rice is ready to eat.


Have your parent help you get ready for this experiment.
