Talk about why people might take a bus rather than a car. Show class a gallon container filled with water. Have students conduct a survey for homework. Instruct them to keep track of all the different types of trucks they see in one week. Collect all the information and record it on a large class chart.
Students can classify the trucks by the type of work they do.
In advance, you might draw chalk tracks for the train to follow. Let children take turns being the engineer, riding in the front car, or the locomotive. The engineer can wear a cap, and use the whistle to signal the rest of the cars to stop, go, or get ready to stop at the next station. Unfold the paper so it lies flat. Turn the paper over.
