Investigation and Experimentation 7. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: a. Select and use appropriate tools and technology (including calculators, computers, balances, spring scales, microscopes, and binoculars) to perform tests, collect data, and display data. c. Communicate the logical connection among hypotheses, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence. d. Construct scale models, maps, and appropriately labeled diagrams to communicate scientific knowledge (e.g., motion of Earth’s plates and cell structure). e. Communicate the steps and results from an investigation in written reports and oral presentations. Genetics 3. A multicellular organism develops from a single zygote, and its phenotype depends on its genotype, which is established at fertilization. As a basis for understanding this concept:
Lesson Abstract:
The goal of this ETP is to develop a biology lab activity in which students learn the fundamentals of forensic DNA typing by analyzing bubble gum found under a desk to determine who left it there. Students will participate in DNA extraction protocol, PCR protocol, Gel electrophoresis and analysis protocols which will help them gain a basic understanding of molecular genetics principles underlying DNA fingerprinting. Students will create their own DNA profile (fingerprint) by determining if their genotypes for three Alu alleles at three loci on genes 16, 8, and 19 are homozygous or heterozygous.
