Resource Type: Lessons Discipline: Science Grades: Grades K–2 Professional Commentary: This resource details a lesson to demonstrate that simple models can be used to represent real world objects that are not easily brought into a classroom. The lesson is designed to allow K-2 students to create a wave model using two different types of simple models.... Resource Type: Lessons Discipline: Science Grades: Grades 1–3 Professional Commentary: During this activity, children observe, measure, and describe water as it changes from solid to liquid and back again. Guiding questions are provided for teachers.... Resource Type: Lessons Discipline: Science Grades: Grades K–2 Professional Commentary: The activities in this lesson focus on sorting and ordering things so that they can be easily retrieved at a later date. These experiences can provide students with the foundation they will need to address more sophisticated information management problems in the future.... Resource Type: Lessons Discipline: Science Grades: Kindergarten Professional Commentary: Students demonstrate understanding of shadows by creating a physical model of concepts learned. This lesson is part of a series in which students observe the daytime and nighttime sky regularly to identify sequences of changes and to look for patterns in these changes.... Resource Type: Lessons Discipline: Science Grades: Grades K–1 Professional Commentary: In this lesson, students will view objects of various sizes from several viewing distances to discover that their visual field is limited. Students will record what they see and will compare their observations with classmates in an open, nonjudgmental forum.... Resource Type: Lessons Discipline: Science Grades: Kindergarten Professional Commentary: In this lesson, students draw the moon's shape for each evening on a calendar and then determine the pattern in the shapes over several weeks. It is recommended that students make observations for at least two months.... Resource Type: Lessons Discipline: Science Grades: Grades PreK–Kindergarten Professional Commentary: Students take seasonal walks and then record and discuss their observations. They also collect and graph data about the types of clothing worn in each season.... 8 What Makes Shadows?: Observing and Drawing Shadows Resource Type: Lessons Discipline: Science Grades: Grades K–1 Professional Commentary: Students learn about shadows as they observe and draw the shadow of a classmate. In the extension activity, students observe and discuss shadows changing over time.... 9 Water 2: Disappearing Water Resource Type: Lessons Discipline: Science Grades: Grades K–2 Professional Commentary: During this lesson students observe the amount of water in an open container over time, and they observe the amount of water in a closed container over time. Students will compare and contrast the sets of observations over time.... 10 Sky 1: Objects in the Sky Resource Type: Lessons Discipline: Science Grades: Grades PreK–Kindergarten Professional Commentary: Students investigate objects in the daytime and nighttime sky.
