Praise for Honors Physics Essentials:
"This book is thorough and entertaining. The physics concepts are explained clearly enough for anyone to understand." -- Jeff, Physics Teacher.
"If you are looking for an SAT Physics review book, or a review book for any non-calculus physics test, I'd recommend the Honors Physics Esssentials book. The charts and illustrations helped me organize key information, and I felt like I understood the concepts behind every question on the test." -- Nick, High School Physics Student.
"I highly recommend this book to anyone who is having a hard time with entry level college physics. Quite frankly, I wish my school would adopt this book as our official text." -- Missy, College Physics Student.

Students will independently determine the resistivity of an unknown material (Play-Doh) using common electrical equipment available in the lab. Students have been introduced to Ohm’s Law and the Resistance of a Resistor formulas previously, and have had a very brief introduction to building electrical circuits from a schematic from the “Resistivity” Lab. Students have also used ammeters and voltmeters in the resistivity lab, though all the equipment is still quite unfamiliar.
The goal of this activity is to reinforce Ohm’s Law and the resistance equation in a practical sense, while guiding the students to develop their own experimental procedure and analysis in an inquiry-based format. The added challenge of students working with circuit schematics to design and build their own circuits will also provide them a head start into our next activities, focused on series and parallel circuit analysis.
Objectives: CIR.A2 I can utilize Ohm’s Law to solve for current, voltage, and resistance.
CIR.A3 I can calculate the resistance of a conductor
CIR.B3 I can use voltmeters and ammeters effectively
DC Power Supply
Brief webquest to introduce students to the APlusPhysics site and resources, and walk them through the registration process.
An end-of-kinematics / beginning-of-dynamics concept mapping exercise in which students build a concept map to create a "big-picture" look at what has been studied so far. The current version assumes students have access to Inspiration software, though I have also done this with index cards and string, poster paper, etc. The end-of-activity group discussion typically centers around transitioning from describing motion to causing motion, which introduced the concept of forces, making this a great transition activity from kinematics to dynamics.
An introductory electrostatics lab in which students utilize electroscopes, Vernier charge sensors, and the standard rubber and glass rods (with fur, wool, etc.) to explore electric charges and their basic properties.

Students use their knowledge of acceleration and kinematic equations to find the acceleration of two different balls rolling down an incline. A nice "early lab activity" following introduction of the kinematic equations to get students a hands-on application of their problem-solving principles as well as continued development of general measurement and lab procedures.
Description: A simple take-home lab in which students melt marshmallows in a microwave to experimentally determine the speed of electromagnetic waves in air using the wave equation and the given frequency of the microwave.
Objective: Determine the speed of light experimentally
Bag of marshmallows (preferably mini's)

Summary: Minimalist lab in which students determine the mass of a cart.
Purpose: Accurately determine the mass of a cart using Newton's Laws without using any scales, mass balances, spring scales, or "homemade" mass balances.
Overview: Basic introduction to Ohm's Law lab in which students utilize a voltage source, an ammeter, and varying resistors to determine the resistance of each resistor. Calculated (empirical) resistance is then compared to the printed resistance, illustrating the variation in electrical components.

Write up for an open-ended "popper" lab in which students use their kinematic equations to determine the launch velocity of a popper toy.
Popper toys can be found in a variety of places such as Amazon, CVS and Wal-Mart, as well as Oriental Trading.
CVS Spring Toys item number is SKU# 439412, bar code 50428 06656, "Spring Up & Catch Game", $2.99 each or 2/$5
Walmart item number is #ES-41035, 6 to a package for $2.98, called the "Sport Pop-Up Game", bar code 79940 41035
Objective: Moment of Inertia by Inquiry
Description: Students experimentally determine the moment of inertia of six different objects (2 solid spheres, 2 solid discs, and 2 rings) by rolling them down a ramp. They then compare their experimentally determined values to the theoretical values which they calculate themselves.
2 solid spheres
2 solid discs
(note that these items can be purchased as a group set through lab supply vendors, or you may create your own)
Students develop their own procedures for this lab. Note that the students can take one of two paths to determining the moment of inertia of the rolling objects... both result in the same values if derived carefully, and each is a good reinforcement of key concepts students have been studying up to this point in the class.
Students roll various objects down an inclined plane and use their knowledge of rotational motion to determine the moment of inertia of the objects. Two equally valid paths to the answer make this a great inquiry lab, and you can differentiate easily by having advanced students search for BOTH paths to the answer, verifying both paths give you equivalent solutions.
A short lab in which students experimentally determine the absolute index of refraction for Lucite using two different shaped blocks (rectangular, triangular). Easily adaptable to other materials and shapes.
A lab in which students oscillate an extended spring to create standing waves. By measuring the period or frequency of the standing waves, as well as the wavelength, students calculate the speed of the wave using the wave equation.
Ultimate goal of this lab is to have students understand that the type of wave and the medium determine the speed of the wave. The wave equation, holds true and describes a relationship, but the speed of the wave is not determined by adjusting the wavelength or frequency.
Overview: Students experimentally determine the wavelength of a laser using the theory of Young's Double-Slit Experiment.

From my review quizzes, which spanned almost 300 of the 966 MC questions since 2002. (I had many versions. I don't make the kids do 300 questions!) I compiled a list of the 40 most missed questions (by my students anyway) in order.
I also made a youtube video explaining how I think about each question with a little review snuck in.
The most missed topics by my students were
Min and Max values of Vector Addition
Energy Problems with Internal Energy
Diffraction (slit size/wavelength relationship)
Displacement from Area of VT
Estimation (of Weight Force)
Thanks to Dan Hosey for creating this.
Students are presented a d-t graph and asked to create the corresponding v-t graph and formulate an appropriate story around it. Then they are given a v-t graph, asked to produce a corresponding d-t graph, and formulate an appropriate story.
From Barry Hopkins at Severna Park High School
"I use the inexpensive clear plastic storage containers (shoe box size) from the dollar store and a couple of 9 volt batteries. Small pieces of copper wire and aluminum strips are placed into the tubs and water in the various configurations shown on page 3 of the Word document. We eventually print out each group’s results and make copies for everyone, and they use the equipotentials to help them trace out the electric fields.
If you’ve never done this before, you’ll find it’s extremely tedious and time-consuming, so I usually get them to come after school (for some extra credit) to collect the data, rather than waste valuable class time."
