**Lesson Plan Day: 29 **

** **

**Teacher: P. Kirk**

**Subject: Science**

**Course: Chemistry**

**Topic: Density, DA, Percent Error**

** **

**NGSS: **

**C.PM.1: Atomic structure, Evolution of atomic models/theory**

C.PM.2: Periodic Table

** **

**Objectives:**

**Complete the density lab. Apply the learned rules of sig figs to manipulate
the answers and then determine the amount of error of those calculations.**

** **

**Vocabulary:**

**Mass, volume, density, error, percent error, accepted value, determined
value **

**Student:**

**Students will work with partners to measure the mass and volume of regular
and irregular objects to determine their densities. Those densities will then
be compared to known densities and the Percent Error calculated. **

** **

**Teacher:**

**Teacher will copy the lab papers and set up the lab. **

** **

**Resources:**

**Density Lab materials, calculators **

** **

**Evaluation:**

**Density Lab will be graded.**
