Grade Upper Elementary (3) Time 45 minutes Objectives Students will learn the importance of writing clear and accurate procedures write a procedure for making a PBJ samdwih Materials 1 loaf bread 1 jar peanut butter 1 jar jelly paper plates Knife, spoon Standard clean-up equipment Find out if any students have allergies to peanuts before beginning. Introduction Review with students the steps of the scientific method as they have studied them. Focus on the importance of the experiment and the set of directions for how to do the experiment, called the procedure. One of the reasons i he procedure is important is because other scientists must be able to do the same experiment in the same way to see if they get the same results. Today they will be writing procedures for a very important, very difficult task. Procedure 1. The problem Assign students to working pairs. Explain to students that you (the instructor) have just arrived on this planet. You have discovered the greatest thing in the entire universe and want to take it back to your planet, but dont know how to make it, so you need their help. They will work in pairs to write the procedure, the set of directions, for making a peanut butter and jelly sandwich. Show them the materials that you have to work with - a loaf of bread, a jar of peanut butter, a jar of jelly, and a knife. Give students 10 minutes to work on writing the procedure. 2. Making a peanut butter and jelly sandwich At the end of the time, have volunteers read the directions they have written, as you follow them to the letter. Be extremely literal, for example if they say, put the peanut butter on the bread as their first step, place the unopened jar of peanut butter on the unopened loaf of bread. If they say, open the peanut butter, struggle with pulling the cap off. Have students verbally change directions to make them more precise as you go along. Always give the person who gave you the directions the first crack at
