Lesson Plan Title:|Properties of Water|
Grade Level: |10|
Content Area:|Biology I|
Sunshine State Standards or Common Core Standards:|Sunshine State Standards - SC.912.L.18.12 - Discuss the special properties of water that contribute to Earth's suitability as an environment for life: cohesive behavior, ability to moderate temperature, expansion upon freezing, and versatility as a solvent.| Behavior Objectives:|(Three parts: Condition, action, and measurement)Given a model of a water molecule, students will identify the oxygen and hydrogen atoms, the partial positive and negative areas of the molecule, and covalent bonds within the molecule.The learner will correctly identify the 4 main properties of water and give examples of each within 1 minute.| Materials (including technology):|Students: Textbook, Pencil/Pen, PaperTeacher: Classroom board, markers, computer, Powerpoint presentation, Word processor, multiple copies of worksheets to pass out, Warm up :10 -15 Pennies, 10-15 Eye Droppers, Cups, Water Mini Labs: plastic petri dishes, paper clips, ethanol, water in eye droppers, glass slides, water, red food coloring, capillary tubes, straws, ice cubes, NaCl, salad oil in eye droppers, hot platesClosure: Koosh Ball| Hook/Anticipatory Set/Lead-In:Total Time: 15- 20 minutes|Prior to class, the instructor should gather the following supplies: Pennies, Eye droppers, Cups, Water. As students come into class, they should form groups of 3-4 people and pick up a one penny, one dropper, a small cup of water and return to their seats. They will also need a pencil/pen. Once every group has the proper materials, the instructor will hand out the accompanying worksheet (Appendix A). They should explain that each group is going to count how many drops of water will fit onto the top of a penny. The team with the most drops of water on their penny “wins”. As one student is dropping the water onto the penny, another should be counting and recording the results. The other members of the group should be working on the worksheet, consulting their textbook for answers; this worksheet can be completed at home and is not to be turned in. | Procedures:Lecture: ~25 minutesWorksheet: Remaining class timeMini labs – Day 2, 45 minutes. |After the Penny Lab, the teacher should transition into a Powerpoint lecture on the properties of water (Powerpoint attached to lesson plan). The lecture should last for 25 minutes, enough time to get in the necessary information yet short enough to hold students’ attention. The following topics should be covered in the Powerpoint: the physical structure of a water molecule, states of matter, polarity, hydrophobic/hydrophilic substances, high heat capacity, cohesion/adhesion and surface tension, density and solubility. Once lecture is over, students will receive the Properties of Water worksheet (Appendix B) to work on during the rest of class and to complete as homework if not finished. This assignment will be due the following class period at the end of class and will be graded. The following class period, the teacher will set up the class into 6 “centers”. Each center is a mini lab and will focus on a certain property of water, the students should be able to use the knowledge they gained from the previous lesson to effectively answer questions about the properties of water. Each station will have a single worksheet (Appendix C) listing the procedure for the lab and 3-4 questions about the lab and property covered. Students must provide their own paper and copy down the questions and then respond; they can work together but must have their own answers. The work completed during lab time will be turned in a graded on the day of the test. 5 minutes before class is over, the instructor should pass out a study guide and let students know that there will be a test the next class period, topics from both lecture and lab will be covered.| Guided and Independent Practice: |On day 1, students will work...
