The six-grade science classes had a lab in which they experimented with water systems. Running water is a very powerful force that shapes the landscape as it travels down a slope.
On Friday and Monday, April 29th and May 2nd, I went over to Mrs. Dandridge’s class to observe the lab and asked the students what they learned from it.
On Friday, the students wrote out their hypothesis regarding they thought would happen when they used the water system tables.
The following Monday, 6th grader Gisselle Barragan hypothesized that when the table is elevated at the first bar “the land will stay the same and the water stays in the same place.”
They started off their lab by setting up the stream tables, a plastic table with sand in it and a stand with a bucket of water. The bucket has a nozzle that releases water at a controlled rate as it moves down the table to shape the landscape.
They started on the first level then increased the slope. From this experiment, 6th grader Caitlyn Timmons learned how the water traveled faster when the slope was steeper.
After each experiment, the students had to identify the types of water channels that appeared in their sand. There are six different channels: the meander, river delta, floodplain, u shaped valley, waterfall, alluvial fan, braided stream, and oxbow lake.
Being able to simulate water systems right before their eyes, the sixth-graders were thoroughly engaged with this hands-on experiment.
