This lab activity has student groups riding an elevator while a volunteer stands on a bathroom scale in order to get readings on the Normal Force. After conversion from pounds to Newtons, students create 8 Free Body Diagrams showing the forces on the person, the directions of the velocity and acceleration vectors, and calculations for the net force and acceleration experienced by the rider.

Introductory worksheet gives students practice drawing Free Body Diagrams for a simple situation (huskies pulling dog sled) involving 2 vertical forces and 3 horizontal forces. Students write an expression for net force along each axis using the correct symbols/abbreviations and apply the 2nd law to find the acceleration. Follow up questions use kinematic formulas to describe the resulting motion.

This is a fun activity introduces students to the wonderful world of observational astronomy. Includes an explanations of "constellations" and of the "ecliptic", and numerous exploratory activities. Students download the "Star Walk 2" app onto their phones. They are able to aim their phones and get an augmented reality view of stars, planets, constellations, deep sky objects, as well as the current locations of the ISS and the Hubble Space Telescope. The app displays a real-time map of the sk

This assignment/activity engages students in analyzing 12 realistic scenarios where the 3rd Law is at play. Focuses on situations that students find surprising and where common misconceptions occur. Student are given one representation of an interaction and complete the grid with the remaining representations: Pictorial Representation Identity of 2 objects interacting Verbal A/R Counterparts Vectors Labeled with Agent-Object Notation

This perennial favorite lab has students go outside to compete in teams pushing my car and collecting data. I honk my horn for a team to start pushing, and then honk again when the acceleration starts to wane (usually at 6-9 mph). Once data is collected we can return to the classroom and calculate the acceleration and net force for each team. Works best on a slight incline to cancel out rolling friction.

This tutorial explains clearly and intuitively what "pi" is, and how the radian angle measurement system works using the intrinsic properties of all circles. Students learn the natural advantages of this system in simplifying math formulas. The tutorial ends with two example problems computing arc length of angular displacements in both revolutions and degrees.

Students turn a mundane Periodic Table into a very useful reference in this assignment. Following the checklist of 15 tasks (included in this bundle), students annotate their Tables with color coding for metals/non-metals/metaloids, labeling groups with Lewis Dot Structures, valence electrons, oxidation numbers, and also with the customary names for element groups (such as "halogens" etc).

This scaffolded worksheet gives students the Names of 24 ionic compounds, students then look up the cations and anions and deduce the Chemical Formula based on the charges of the participating ions. Includes transition metal cations but only monatomic anions. The final example introduces the concept of polyatomic ions Includes a complete answer key.

This scaffolded worksheet gives students the Names of 28 ionic compounds, students then look up the cations and anions and deduce the Chemical Formula based on the charges of the participating ions. Includes transition metal cations and polyatomic anions. Includes a complete answer key.

A 1 page review of the concepts of Work and Power and their relationship energy transfer and transformation. Students fill in the blanks using a word bank. A good warm-up activity with a partner or a small group. Complete solution is included.

This worksheet has 28 binary covalent compounds: Task: Given a Covalent Comound's Name --> Write the Chemical Formula Given a Covalent Comound's Chemical Formula --> Write the Name Students should see the Naming Flow Chart for Guidance on this assignment.

This worksheet is a grid with both main group and transition metal cations in the columns, and both monatomic and polyatomic anions in the rows. Page 1: students write the corresponding ionic compound names in the cells. Page 2: students write the corresponding ionic compound chemical formulas in the cells.

This worksheet is a grid with main group metal cations in the columns, and monatomic anions in the rows. Page 1: students write the corresponding ionic compound names in the cells. Page 2: students write the corresponding ionic compound chemical formulas in the cells.

Students complete the grid in this worksheet involving rich real-life scenarios of interactions. Students identify the pair of interacting objects, determine if the force exchange is contact or non-contact, express the interaction "verbally", and express the Newton's 3rd Law using Agent-Object notation for the forces.

A 1 page review of Potential Energy, Kinetic Energy, and Mechanical Energy and conservation. Students fill in the blanks using a word bank. A good warm-up activity with a partner or a small group. Complete solution is included.

Using proportional reasoning lets us find quantitative and qualitative answers to Physics and Math problems in a fast and easy way. This 4 page tutorial explains a three step process for approaching these problems, and also has 6 completely worked examples to help the student become a master at solving proportional reasoning problems. Great prep for the AP Physics and other standardized Physics exams.

This tutorial and mini-worksheet explains the rationale for and the steps for creating a Free Body Diagram (FBD). Includes determining the contact and non-contact forces at play, and labeling forces. A short, but challenging, exercise lets students create 2 FBDs so they can practice the steps, and see how the choice of system changes a FBD.

Using the chart in Handout/Tutorial "Visual Metric Conversions How To" the student can quickly, intuitively, and visually convert between the metric units in this practice worksheet.

Using a simple and intuitive visual method, a quantity that uses a metric prefix can be quickly and visually converted to another prefix or to the root unit!

This set of DVT Word Problems are scaffolded to walk students through an organized problem solving process. This includes determining if inconsistent units require a conversion, writing down givens and formula to be used. The first of the 12 problems is completely solved as an example.
