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: 7-8.
Chemical Interactions introduces students to the world of chemical reactions. In this module, students compare the densities of 3 different liquids, explore the inverse relationship between the pressure and volume of a gas, and differentiate between solutions and suspensions. Students then learn about the structure of an atom and the properties of protons, neutrons, and electrons, and are introduced to the concept of an isotope. They build models to demonstrate the 3-dimensional structure of molecules and test various covalent and ionic compounds to see how the type of bond between atoms in the compounds affects the characteristics of those compounds. Then students simulate chemical reactions with models, draw and construct models of isomers of organic compounds, distinguish between saturated and unsaturated fats, and explore the effect of double bonds on their melting points. They use indicators to measure pH and identify common household acids and bases, they discover that bases neutralize acids, they conduct a controlled experiment to determine the factors necessary for oxidation to occur, and they carry out a double replacement reaction and observe the formation of a precipitate.

The 13 activities in Chemical Interactions generally take between 30 and 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.
