Grades K through 2
School: Indian Land Elementary School, Fort Mill, SC
Planned By: Denise C. Trufan
Original Author: Denise C. Trufan, Fort Mill
ENGAGE-
TW (Teacher will) read an excerpt from IN THE DARK by Stan and Jan Berenstain to begin discussion about shadows.

1. Discuss how shadows make people feel.

EXPLORE -
Over the period of the next six science classes, SW (students will):

1. Explore shadows inside and outside of the classroom both of inanimate objects and animate objects, including themselves and friends. They will trace a peer's shadow on the ground and trace an object's shadow in their journal.

2. Measure shadows using nonstandard measurement, with assistance from teacher.

EXPLAIN -
1. Discuss and experiment to find out what is necessary to make a shadow (light, something to block the light, a surface for the light to fall on), by using sunlight and flashlights to produce light to make shadows.

2. Observe that shadows change shape and size when the object is closer and further from the light and/or changes position.

3. Write shadows and draw their shadow in their Science Journal.

EXTEND -
1. Cooperate to write and illustrate a book about shadows.

2. Participate in video about shadows, including a cheer that tells about requirements to make a shadow, which will be podcasted.

EXPLAIN -
How shadows are made.

EVALUATE -
TW informally observe student responses and journal entries.

RUBRIC -

Comments
Students benefit from hands-on learning. The knowledge they gain becomes their own. They have fun learning this way too. There are about five hundred students who will benefit from this project at Indian Land Elementary.
Thank you for this opportunity.
