Dear Johnny,
Thank you for speaking to our class last Thursday. We’ve all learned a lot about how you make your weather forecasts. After your left, we made a list what we had learned. Then we set up the small weather station outside your classroom. From tomorrow on, one student in the class will be the weather forecaster every day. He or she record data in our weather book. In a few month, we will start drawing graphs and charts what show our weather patterns here in Nebraska. Which you can see, your visit has been given us a lot of ideas. Thank you so much for opening our eyes to this interested subject.
Yours,
Jack
