Ms. Heinz Biology 1 Day 1 Lesson 2 50 minutes Objectives: TSW identify important equipment used in a science lab. TSW describe the proper use of given lab equipment. (Bio 1a, DOK 1) Materials: lab equipment, markers/colored pencils, mini-posters Bellwork: Name a hobby or something you enjoy doing (sports, cooking, school work, carpentry, etc.) What equipment or tools are necessary for you to do this? List as many as possible. (5 minutes) Bellwork: Discuss bellwork with students. Science is also something that requires lots of tools and equipment, and you have to know what they are and how they’re used. You are constantly observing things and measuring things in science, and the equipment we use makes us more effective. Today you’ll learn several different pieces of equipment, and you’ll describe how certain things are used. (5 minutes) Procedures; 1. Pass out the lab equipment worksheet and handout: How to Read a Graduated Cylinder to each student 2. Have student skim the worksheet and identify the lab equipment they’re already familiar with. 3. Pick up the graduated cylinder and have the students look at their handouts. Describe the meniscus and demonstrate the proper way to read its volume. Explain how the volume will seem different if your eyes are above or below the meniscus, thus they should be at eye level. Pass the graduated cylinder around. Allow students to look at it. 4. Next, students will fill in the two columns on the worksheet for graduated cylinders. Explain that this is what they will do for every piece of equipment on the 2 page worksheet. 5. Have every piece of laboratory equipment available for viewing and handling. Students will continue to work on filling out their sheets. 6. Students will then pick once piece of lab equipment to make a poster out of. 7. Collect all work (35 minutes) Closures: Today we learned about laboratory equipment. What are the different types of equipment? How are these pieces of equipment used in the lab? Next class, you will be taking a pretest. (5 minutes) Assessments Informal: Teacher will question (M) students on the different types of lab equipment (C). Formal: Students will complete an exam (M) on laboratory equipment (C). Grades will be recorded in the gradebook (D).
