  • 1. TODAY IN SCIENCE YOU WILL NEED:  Pencil, Calculator, Log #4 (update)  BioChemical Lab – 3 sheets 6 sides Bookshelf-Please Staple  Chemistry of Living Things Booklet Was due yesterday
  • 3. Highlight Scientists use experiments to search for cause and effect relationships. In other words, they design an experiment so that changes to one item cause something else to change in a predictable way. These changing variables can be identified as independent, dependent and controlled. We as scientist focus our observations on the dependent variable to see how it responds to the change made to the independent variable.
  • 4. BIOTECHNOLOGY VIRTUAL LAB Topic: Name Biotech Virtual Lab Class Terminology Period Date ECB -European Corn Borer Yield -Amount of crop production Infestation -Overrun with pests and parasites Independent Variable -Types of Corn & their level of infestation: BT123, Super Harvest –NonBT; BT456; Golden Crop – NonBT Crop
  • 5. BT Corn - BioTransgenic Corn Growing Conditions for Corn What is being Controlled Soil, moisture, temp, light & nutrition -Soil, nutrients, watering amounts, light, heat, infestation level
  • 6. Virtual Lab How does the European Corn Borer affect the yeild of corn? Since we know that the ECBs loves to eat corn…what are the farmers afraid of in terms of corn yield? Kernel mass per each ear of corn= “weighing” the total amount of corn kernels produced by one ear of corn.
  • 7. Hypothesis Based on what you know about the experiment….. If we test four different types of corn under similar conditions and change only the infestation level, then we should be able to determine and give evidence for which corn type will provide the
  • 8. BIOTECHNOLOGY VIRTUAL LAB COLLECT YOUR DATA ECB Level Mass of 1st ear Mass of 2nd ear Mass of 3rd ear Average (show work)   None           Low         • There are 8 different data collection tests. • Continue until all Data is Collected.
  • 9. TODAY’S TASK LIST 1) Work with a partner from your table OR individually. 2) Pick up your Assigned Computer. 3)You will be held responsible for its well- being. 4) Ask Clarifying Questions as needed. 5)Begin experiments & collection of data 6) Our Goal is complete 8 tests by the middle of class tomorrow.
  • 10. HOMEWORK 1)Test #3 Corrections due tomorrow. 2)We will be working in class on the Virtual Lab tomorrow and we will collaborate our conclusions on Friday. 3)This lab is not due by Monday of next week.
