1. Grade Level: 4th
2. Theme/Title of the day’s lesson with a brief description:
Flood!
As a class we have discussed the purpose and use of transportation on the Mississippi River. We have also talked about how useful the river is. Today students are going to create an experiment to see the negative effects a river can have on a community. This lesson will also include matter on the resent flood in Winona and the surrounding areas.
3. Materials/resources needed:
- 4 pictures from the Winona Historical Society
- Copies of the worksheet, “Overflowing the Banks”
- Access to the website: http://www.mnstories.com/archives/2007/08/winona_flood.html
- 4 large flat containers or trays with sides (Aluminum baking pan)
- A sufficient amount of model clay to cover the bottom of the pans
- Water
- Drawing paper
- Pencils
4. Goal(s) for today’s lesson: (This shows people how you lesson “fits” into the MN standards.)
Physical Science: Properties and change of properties in matter.
Earth and Space Science: Properties of earth materials.
5. Objectives for today’s lesson: (This tells people what kids will know or be able to do at the end of the lesson.)
- The students will construct a model of the river system.
- The students will understand the effects a flood can have on the river system and the land surrounding the river.
6. Lesson Preparation
a. Make transparencies of the pictures taken from the Winona Historical Society.
b. Make copies of the “Overflowing the Banks” worksheet.
c. Have materials set up and ready at 4 different stations.
7. Procedures
a. Introductory experience
i. Review with the students, what they have learned in the past few days. Use the pictures of steamboats used in yesterday’s lesson to help them remember what was talked about.

a. Introductory experience
i. Review with the students, what they have learned in the past few days. Use the pictures of steamboats used in yesterday’s lesson to help them remember what was talked about.
ii. Also review with the students the uses of the river. Show the pictures of the “Highways of Water” and “Highways of Steel.”
iii. Tell the students that today they are going to create an experiment to show the negative effects a river can bring. This will also show the effect weather can have on transportation.
b. Developmental experiences
i. Show the students the videos from the website: http://www.mnstories.com/archives/2007/08/winona_flood.html.
ii. Pass out the worksheet “Overflowing the Banks” to each student. Split up the class, and have each student go to one of the four different stations set up.
iii. Within their group, have them sketch a rough map of a river that will run from one end of their pan to the other, at least 3 cm (1 inch) wide. Add several tributaries (small streams) that will feed into your river as it heads downstream.
iv. Using the clay, build a model of your map inside the tray, making sure that the banks of the river are approximately 1 cm deep.
v. With the tray lying flat on a desktop or table, pour water into the streams and river so that the water level is not quite at the top of the 1 cm.
vi. Tip the model slightly so that the water runs downstream. Notice how the tributaries feed into the river, increasing the depth of the water as it flows. No pour more water into the model from the top to simulate increased rain flow into the system. Observe what happens.
vii. After the experiment is complete empty the water and clean up the area around.
c. Culminating experience (closure)
i. Have the students return to their desks.
ii. Discuss the Winona flood with the students. Allow for any personal experiences. Discuss with them, the effects of transportation when the flood occurred.
iii. Discuss the effects of transportation when an even bigger flood occurs.
iv. Using creativity, have the students write two paragraphs discussing what other modes of transportation are affected by Mother Nature, and how they are affected.
8. Assessments used during the lesson:
- Class experiment on a flood simulation.
- Completion of a short writing activity to check for understanding.
