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. |
