“The kids loved the hands on learning making clear connections to science concepts. The teacher loved the simple prep and activities. The video step-by-step instructions for students were very manageable.”
· Tara · Teacher
“Students had fun and stayed engaged. I really appreciate the step by step instructions. It makes the experiment more meaningful and the students can follow along.”
· Connie · Teacher
“The students loved the hands-on activity where they got to make sand and then touch it. They enjoyed being scientists and pouring the water in to each cup to make the mud. They loved "playing" in the mud. The whole activity was a huge hit!!”
· Polly · Teacher
“The students really enjoyed the fact that they got to touch the 'dirt' without getting dirty :)! The conversation about where to build a city like this after the activity was also impressive. Thank you! ”

“As usual, a wonderful lesson in which the hands-on activity brought the topic to life. Students were extremely engaged and the soil tests were fun and informative.”

“My students loved making observations of the different soil types. They also loved learning that mud isn't just goopy and dirty but can be an important natural resource to build homes and schools. ”

In this lesson, students explore a unique building material: mud! The properties of mud depend on the properties of the soil it's made from. In the activity, Mystery Mud, students use models of sand and clay soils to investigate how the properties of soils can differ. They use their observations as evidence to classify each soil model based on whether or not it would make mud that’s good for building.

Prep Instructions

We suggest students work in pairs. You will need access to water for this activity.

Prepare Dixie Cups

Divide your Dixie cups into three equal piles. Use a marker to write “A” on each cup in one pile, write “B” on each cup in the second pile, and write “C” on each cup in the third pile.

Add 2 teaspoons of cornmeal into each cup that is labeled “A.” This is a model for sandy soil.

Add 2 teaspoons of flour into each cup that is labeled “B.” This is a model for clay soil.

Add 1 teaspoon of flour and 1 teaspoon of cornmeal into each cup that is labeled “C.” Gently shake these cups to mix the cornmeal and flour together. This is a model for a mix of sand and clay soil.

Prepare Water Cups

Fill each Solo cup about a quarter full of water. Each pair of students will only need a few spoonfuls.

Teacher Tip

Making a mud model is very fun, but it can also be distracting! We recommend waiting to distribute the cups of water and spoons until Step 5 of the activity, after students have explored the dry soil models.

State Soils. We learned that the type of mud you can make depends on the type of soil where you live. If you live in the United States, did you know that every state has its own state soil?

You can learn all about your state's special soil and explore its properties!
