My Favorite Stuffed Animal Objectives: After completing the lesson, students will be able to:  Use a metric ruler to measure length  Estimate the size of an object in metric units Key Question: "How big is my favorite stuffed animal?" Overview: The appeal for students in this lesson is that they get to work with their favorite stuffed animal. Students measure the dimensions of their animals in centimeters, and then try to guess which animal has which set of measurements. Time Required: 45 minutes (1 class period).  Materials:

For each student  Metric ruler  Stuffed animal  3" x 5" note card

 Procedure:  Give each student a metric ruler and a note card. Have them measure the various parts of their stuffed animals, and record the data on their note card, along with their name, and the name of their stuffed animal. When everyone has finished, place the animals on display in the front of the class, and collect the note cards. Read the measurements from one of the note cards, and have students guess which animal is being described. Repeat until end of class. Remind each student to bring a 2-liter plastic soda bottle to class for the next lesson. Assessment:  Accuracy of measurement as recorded on their note cards Homework: Read "Measuring Liquid Volume," p. 31 in the Inquiry Skills Activity Book, and answer the questions  Bring a 2-liter plastic soda bottle to class for the next lesson OUSD Science Content Standards (State of California Science Content Standards):  #1-b (7-b)References: Inquiry Skills Activity Book. Upper Saddle River, New Jersey: Prentice-Hall, Inc., 2001, p. 31. Notes:             It is a good idea to bring in a supply of stuffed animals for those students that "forget" to do their homework. The unused animals can be added to the display to make the estimation segment of the lesson more challenging.
