Inquiries in Science® Biology Series - Help your students understand hard-to-grasp science concepts. Using a learning cycle of engage, explore, explain, extend, and evaluate, each kit features lab activities designed to actively engage students in learning essential science concepts through guided inquiry. Topics addressed by the kits were organized and selected based on data from numerous sources, including the National Research Council's National Science Education Standards, AAAS's Project 2061 Science Benchmarks, NAEP's Science Framework, and state science education standards from across the US.

The Changing Over Time Kit includes: Lab supplies (classroom-friendly E. coli samples, ampicillin antibiotic, materials to prepare Luria broth agar plates, and supplies to conduct an inquiry experiment) Plus a teacher’s manual with instructions Background information Reproducible student sheets Student questions Extension activities Suggestions for differentiated instruction. Kit Refill replenishes all perishable materials; price includes shipping and handling.

Grades 9–12. Students explore the evidences of evolution through a variety of guided inquiry activities. First, these investigations introduce modern technologies that aid in the classification of phylogenic relationships and explore the anatomical similarities between evolutionarily related organisms. Students then use their knowledge to design and conduct an experiment based on antibiotic resistance.

• Observe antibiotic resistance in bacteria
• Discover how evolutionary relationships influence organism classification
• Practice microbiology lab techniques

Note: Order the Kit Refill with the perishable materials included or with a prepaid coupon to request the perishables later at your convenience. Contact us or return the coupon at least 2 weeks prior to requested delivery date to ensure prompt arrival of materials.
