Laura Herrick June 5 2008 Lesson Plan Title Better Boiling Experiment Foss based lesson Key Concept s in this lesson Inquiry and investigating systems Grade Level 5th Grade Section 1 WHAT YOU WANT STUDENTS TO KNOW BE ABLE TO DO OR FEEL UNDERSTAND Standards addressed EALRs GLEs EALR 2 Inquiry The student knows and applies the skills processes and nature of scientific inquiry Component 2 1 Investigating Systems Develop the knowledge and skills necessary to do scientific inquiry GLE 2 1 2 Understand how to plan and conduct simple investigations following all safety rules Lesson Goals For students to gain an understanding of inquiry and investigating systems through a boiling water experiment Specific Objectives Given the opportunity to experiment with bringing different temperatures of water to the boiling point the opportunity to fill out an individual data sheet as well as a class data sheet and a class discussion students will be able to work on developing the knowledge and skills necessary to do scientific inquiry Primary Learning Targets Circle Appropriate Targets Be sure learning activities are congruent with targets chosen a Knowledge d Create a Product e Dispositions b Reasoning Proficiency c Performance Skill Section 2 HOW WILL YOU KNOW THAT THE LEARNING TARGETS WERE MET Preassessments Align with EALR s and GLE s You want to find out where they are on your learning targets Attach instruments if appropriate Formative Assessments How are your students progressing toward goals Attach instruments if appropriate The students individual data sheets on their predictions and findings for the amount of time it took to boil hot room temperature and cold water As well as statements about what they learned from doing the experiment Summative Assessment Be specific about how your assessment aligns with EALR s and GLE s Attach instruments if appropriate Section 3 HOW WILL YOU HELP YOUR STUDENTS MEET THE LEARNING TARGETS Scripted guiding questions that you will ask your students You may want to include some possible answers you might get You certainly want to be prepared to respond to a variety of answers 1 Room Arrangement 4 Long tables arranged next to outlets with 3 portable electric burners on each table Materials Needed 12 portable electric burners 12 pots 36 metal cans 48 oven mits 24 pairs one for the right hand and one for the left hand 25 plastic safety glasses 36 candy thermometers data sheets have columns on top labeled cold water hot water and room temperature water On the side the rows are labeled starting temperature estimate of time it will take for each temperature of water to boil and actual time it took the water to boil sink with running water dry erase board or chalk board large chart on the board that is a copy of the data sheet to show the classes predictions and results Accommodations For Special Needs e g ELL 504 ADA extra support by the teacher safety training and extra support by an assistant teacher if needed 90 minute Lesson Activities Label each step in the process Activating Prior Knowledge Disequilibration Elaboration Crystallization Time 5 7 minutes What Teacher Does What Students Do Introductory Activity Today we are going do a scientific experiment where we will find out what temperature of water boils faster I will pass out data sheets with the help of one of the students On the top of the data sheet write your name and the date Now think about what you know about boiling water Have you ever boiled a pot of water at home to make pasta How long did it take the water to boil and approximately what temperature was the water What does boiling water look like when it is a roiling boil Write your predictions of how long you think it will take to boil cold room temperature and hot water on your data sheet The teacher models writing the name and Students may say water with lots of bubbles that is the date and has students write their moving quickly in the pot sometimes bubbling up and predictions on their data sheet as well as over the pot putting it on the large data sheet that is Students may answer saying 5 minutes for warm water attached to the board and 10 minutes for cold Time 4550 minutes Notice that there are four long tables in the room with electric burners on them What kinds of safety rules do we have when we are working with boiling water and hot electric burners The teacher clarifies any missing safety instructions calm bodies low voices ask questions if unsure of safety rules Safety rules are displayed in large writing on a large piece of paper clearly visible from the experiment area You will work together with the partner you are sitting next to partners are preplanned based on group work training done previously and teacher s understanding of student ability and respect for each other Everyone has an important role to play in this experiment I need all of you to participate because all of you are scientific investigators and your predictions and conclusions are a very important part of all of us gaining a deeper understanding of how long it takes water to boil A prediction is what you thought was going to happen before the experiment A conclusion is what you find Students may say that we wear plastic eye glasses to protect our eyes oven mits to protect our hands and be very careful around the electric burner keeping hands clothes and hair away from the burners at all times Students put on their safety glasses decide who will be taking the temperature of the water and who will fill the cans with water and put it on the burner to boil One student fills the cans with room temperature One student takes the temperature of each can of water cold room temperature and hot water The other student puts one can of water at a time on the burner They both record their predictions of length of time to boil for each can temperature of water time the water was put on the burner and time the water began boiling and added up the minutes Then copy their information on the class data sheet 2 out by doing the experiment Each pair has their names taped to a table by a burner There are three cans a pot two pairs of safety glasses and two pairs of oven mits and a candy thermometer by each burner Decide in your pair who will be in charge of boiling the water and who will take the temperature of the water Each of you will record your prediction on your data sheet of how long it will take for each can of water to boil You will fill one can of water with cold water one
