Lesson Plan : Density Problems

Teacher Name:
 Mr. McKie
Grade:
 Grade 11-12
Subject:
 Science

Topic:
 Density
Content:
 Density, mass, volume, grams, liters, cm x cm x cm formula,
Goals:
 1. Define density 2. Use lab equipment to find appropriate and useful measurements. 3. Be able to use the density formula to solve for density, mass or volume
Objectives:
 1. Students will be able to define density 2. Student will be able to identify the density of different substances by using D=m/v 3. Students will be able to use the density triangle to solve for different variables.
Materials:
 snack size 3 musketeers bars regular size 2 musketeers bars; graduated cylinder, triple beam balance, ruler,
Introduction:
 Pre-assessment quiz (its called a quiz so the students will try, but it doesn't count as a quiz...rather an assignment completion). Purpose of this is to see how much they understood from the Guided Outline and previous science classes.
Development:
 Smart Board PowerPoint on density. Slides are kept short and to the point. Density Triangle -- to limit the need for algebra and math. Density Lab-- I will model how to find the mass of an object and the 2 different ways that you can find volume of an object (by a ruler and by the graduated cylinder)
Practice:
 Class examples located on the white board. Students will be in partners and they will complete all 5 problems on the white board together. They might have to present the material in the front of class
Accommodations:
 Copy of notes for C.J. (as requested on IEP) ** Student who feel that they understand the objectives will complete only the odd numbers on the homework and their homework will be graded on accuracy; others who do not feel comfortable will complete all the problems for completion credit.
Checking For Understanding:
 Debrief of the lab -- does both objects have the same density? The answer should be yes, because they are made from the same materials. Size does not matter.
Closure:
 Density Problem were for homework, if students have time after the lab students can start their homework.
Evaluation:
 If students are able to complete in the in-class problems and show no problems in the lab computing the density they should have successfully completing the learning targets for today. If students are have trouble in a particular area, there is time during and after the lab for students to clarify any misunderstandings.
