Program Overview
The Delta Science Module (DSM) series has 51 life, physical, and earth science units for grades K-8 that emphasize science concepts, science content, and process skills. The series includes 12 modules for grades 5-6 and 8 modules for grades 6-8. Each requires about 3 to 4 weeks to complete and includes a teacher's guide and materials for a class of 32 students.
Teacher's Guide
Recommended grade level:
5-6.
In Color and Light students investigate the relationships between pigments, color filters, and the light that strikes them. In this module, students observe the properties of light by experimenting with prisms; they mix different colors of pigments, observing the new colors that form; and they use paper chromatography to separate a mixture of pigments. Students also use color filters and light sources to investigate and compare the processes of subtractive and additive color mixing. They see how colored light can affect the way colored objects look, observe how primary colors can be used to produce full-color images, and learn to create colors by combining primary colors. Students then observe the effect that color filters have on what we see, apply their knowledge of how color filters affect sight to create the illusion of a 3-dimensional object from a 2-dimensional drawing, explore afterimages, and make and use multicolored wheels to observe the "persistence of vision" phenomenon.
The 13 activities in Color and Light generally take 30 to 60 minutes each and can be done by students working individually or in groups. In addition to directions for activities, the teacher's guide provides a module overview, a schedule of activities, objectives for each activity, background information, materials management and preparation tips, sample answers to discussion questions, teaching suggestions, and reinforcement activities. Also included are reproducible activity sheets for student work and a performance-based assessment. A "connections" feature at the end of each activity provides suggestions for extending or applying the concepts addressed.
