Watershed Experiment and Water Flow

Laurel Sebastian, an educator with Kids for Debate, guides viewers through creating a watershed model using paper and markers. The tutorial involves crumpling paper to form a landscape, marking water flow paths with blue markers, and ridge lines with brown markers. Observations are made by spraying water on the model to see if it flows as predicted. The concept of watersheds is explained, highlighting how water flows over land to bodies of water. The video encourages viewers to consider watersheds in their environment and how they connect to larger water systems.

What is the first step in preparing for the watershed experiment?

• Draw rivers and lakes on the paper

• Spray water on the model

• Crumple the paper into a ball

• Gather materials like parchment paper and markers

What can you use if you don't have a spray bottle for the experiment?

• A hose

• A sponge

• A cup of water to flick onto the model

• A watering can

What should the crumpled paper resemble once unfolded?

• A mountain with high points and ridges

• A flat surface

• A plain with no features

• A smooth hill

What is the purpose of using magnets in the experiment?

• To weigh down the water

• To keep the paper in place

• To decorate the model

• To mark the starting point of rivers

Which type of marker is recommended for tracing water flow paths?

• Washable blue marker

• Pencil

• Permanent marker

• Red marker

Why is it important to trace ridge lines with a brown marker?

• To make it easier to crumple the paper

• To create a pattern

• To identify high points where water will shed

• To make the model colorful

What should you observe when spraying water on the model?

• The temperature of the water

• The weight of the paper

• The flow of water and its interaction with the markers

• The color of the paper

What should you do if your predictions about water flow are incorrect?

• Ignore the results

• Try a different shape of mountain

• Change the color of the markers

• Stop the experiment

What is a watershed?

• A type of marker used in the experiment

• A tool for measuring water flow

• An area of land where water flows over or through to a body of water

• A type of paper used in experiments

How can you identify watersheds in your own backyard?

• By measuring the rainfall

• By observing where water flows during rain or snow

• By checking the soil type

• By planting trees
