Reflection: Self-Talk Exploring Erosion by Wind, Rain, and Waves - Section 3: Erosion Stations 1-2-3


It worked really well to insist that students initialized which steps they would do! It ensured that the steps were read, and classmates could discuss what the directions meant. One of the overarching goals I have for my class, is for them to read directions and to check that they understand the directions. Although, I did need to remind teams that the directions said for them to 'gently' make waves.

All that said, teams thought they understood the width of the beach, they saw this as a side to side measurement, as in the width of the container. Next time, I will be sure to review this term with the kiddos. 

Here is the definition for 'width of beach': The horizontal dimension of the beach measured at right angles to the shoreline measured from the extreme low tide to the landward limit of the beach. 

I as well as the students wanted to see some dramatic changes, but due to wet sand for the wind station and dry and loamy soil for the erosion station, 'erosion episodes' were less than dramatic.

My lesson and theirs: erosion can be a slow process, even when erosion episodes are contrived, damp sand does not move much even with a box fan and loamy soil will absorb lots of water. These lessons were all talking points we had during our wrap up session, which we realized would help us answer our anchor question: How can we prevent or slow down water or wind from shaping the land?

Bottom line. Remember it is O.K. for the lab to not work out in the way you intended learning still happens, observations can still be made, scientists learn to let go of expectations and just allow the experiment to take its course. WOW life learning yes?

Exploring Erosion by Wind, Rain, and Waves

Unit 4: Unit 4 - Surface Water and Landform Interactions
Lesson 11 of 18

Objective: SWBAT make observations of erosion processes caused by slope, waves or wind.

Big Idea: Students 'speed up' time to observe how wind, waves or slope may change surface features.
