Note: This lesson is part of this unit’s Anchor Layer. If you have the Anchor Layer turned on, we recommend teaching all of the lessons in this unit in order.

The anchor phenomenon for this unit is based around some surprisingly large floating objects that can be found in ponds around the world.

During the introduction, students generate observations and questions about the phenomenon and create a list of possible explanations for the phenomenon.

Students will gather clues during and after each lesson in this unit to help them improve their understanding and explanations. It is important to encourage students to recognize that even if they don't know the perfect answer yet, they are going to learn a lot throughout the unit and will have an opportunity to revisit the phenomenon over time.

Set Up Your Classroom

Set up your classroom by creating a class "See-Think-Wonder" chart. You will start the chart today, and you will add to it over the course of the unit.

For the See-Think-Wonder charts, you can use chart paper or a space on your board that won't be erased to create a whole-class chart. If you would like to have students complete the See-Think-Wonder charts on an individual basis, here is a blank chart.
