**Getting Started** 5 minutes

- Review of the previous day’s lesson and concepts. Connection to today’s lesson.

**Activity #1: Math Basics for Modelling** 15 minutes

- Review coordinates on a graph; connect coordinate system to Spaceland.
- Create turtles in different quadrants of Spaceland and use new blocks to make turtles move in a specific direction.

**Activity #2: Inspecting the Water Pumping Model **10 minutes

- Identify familiar coding blocks
- Decode model in pairs.
*Optional*: connect prerequisite concept review from Lesson 1 to ask what is and is not reflected in the model.

**Activity #3: Adding Slider for Evaporation Rate **15 minutes

- Add a slider for evaporation rate.
- Run an experiment using the evaporation slider.
- Discuss the results and relate them to the hydrologic cycle.

**Wrap-Up** 5 minutes (Reflection)

- Discuss limitations of the model and think of ways of improving it.
