Understanding By Design 1-Page Template Title: DNA Extraction from Peas Stage 1: Desired Results Content Standards B.1.21 Understand and explain that the information passed from parents to offspring is transmitted by means of genes which are coded in DNA molecules Understandings Genetic information is passed from parents to offspring through genes that are found in our DNA, which can be extracted from various living things. Essential Questions Knowledge & Skill What exactly does DNA look like with the Skills naked eye and with a microscope? Read and follow a lab procedure. Do field work RESPONSIBLY. Keep good records of data collected using equations if necessary. Analyze the data collected. Draw conclusions from that data. Collect information and put into a lab report. Ask questions when you need help Knowledge Introductory use of digital microscopes Basic steps of mitosis (PMAT) What does a grasshopper look like Basic DNA structure (double helix) Stage 2: Assessment Evidence The students will be graded through the performance of the lab activity, the production of the digital photos in the lab report, behavior during the lab and their use of technology throughout the time spent on this activity. They will be doing other book activities as well during time. At the end of the topic of study there will be a test discussing DNA and genetics including questions about the lab activity. Performance Task Summary Rubric Titles Formal Lab Report Rubric for all activities Extract and observe the DNA strands from Behavior/On Task Rubric for all activities pea plants Use of Technology Rubric for all activities Self-Assessments Other Evidence, Summarized Formal Lab Report Rubric for all activities Test over DNA and genetics will include Behavior/On Task Rubric for all activities questions about this lab activity. Use of Technology Rubric for all activities DNA extraction lab will include digital pictures taken of the DNA strands extracted during the lab. Stage 3: Learning Activities LESSON SUMMARY: This lesson introduces DNA, genes, chromosomes, and the chemicals that make up DNA. Students will do an experiment to separate DNA from peas. WHERE ARE WE HEADED? We are headed into the topic of heredity and genetics. This lab will be a great introduction to the students and allow them to see something that they usually cannot. HOW WILL STUDENTS BE HOOKED? Students are easily hooked by lab activities where they can get messy and be able to work in groups. WHAT OPPORTUNITIES WILL STUDENTS HAVE TO BE EQUIPPED, AND TO EXPERIENCE AND EXPLORE KEY IDEAS? Throughout the lab, students will be able to ask questions, explore the idea that you can actually remove DNA from an organism, and know how that chemical stuff that makes up DNA can actually carry all of our genetic information. WHAT OPPORTUNITIES WILL BE PROVIDED TO RETHINK, REHEARSE, REFINE AND REVISE? As the students are working in groups they consistently have time to revise and refine their knowledge of the topic of DNA and genetics. Also, at the end of the lab there will be a question/answer time for the students to get any information clarified that they may need. HOW WILL STUDENTS EVALUATE THEIR WORK? The students can evaluate their own work via the rubrics provided for the DNA activities. They can also quiz each other and work together to prepare for the test.
