Distinguish between scalar and vector quantities and assess which should be used to describe an event.


General Information

Subject Area: Science
Grade: 912
Body of Knowledge: Physical Science
Standard: Motion -

A. Motion can be measured and described qualitatively and quantitatively. Net forces create a change in motion. When objects travel at speeds comparable to the speed of light, Einstein's special theory of relativity applies.

B. Momentum is conserved under well-defined conditions. A change in momentum occurs when a net force is applied to an object over a time interval.

C. The Law of Universal Gravitation states that gravitational forces act on all objects irrespective of their size and position.

D. Gases consist of great numbers of molecules moving in all directions. The behavior of gases can be modeled by the kinetic molecular theory.

E. Chemical reaction rates change with conditions under which they occur. Chemical equilibrium is a dynamic state in which forward and reverse processes occur at the same rates.

Lesson Plans

Name Description
The Adventures of "Shelly the Sea Turtle"

This is a hands-on activity that will keep your students engaged while learning about vectors. Students will create a map using provided coordinates that will plot the "Adventures of Shelly the Sea Turtle."

Students are given the opportunity to be creative and distinguish between scalar and vector quantities and assess which should be used used to describe an event.

X Marks the Spot

This inquiry-lead activity that will engage students to discover the distinguishing qualities of scalars and vectors via a treasure hunt.

Florida Vacation Project- Distance, Displacement, Speed and Velocity

This is a culminating lesson for a unit on Motion. Students will be asked to plan a vacation around Florida that includes 5 destinations. By generating and analyzing their own data students will apply knowledge of distance, displacement, speed and velocity to a real world experience.

Olympic Snowboard Design

This MEA requires students to design a custom snowboard for five Olympic athletes, taking into consideration how their height and weight affect the design elements of a snowboard. There are several factors that go into the design of a snowboard, and the students must use reasoning skills to determine which factors are more important and why, as well as what factors to eliminate or add based on the athlete's style and preferences. After the students have designed a board for each athlete, they will report their procedure and reasons for their decisions.

Motion: Speed and Velocity

In this lesson students should be able to :

  • Identify appropriate SI units for measuring speed.
  • Compare and contrast average speed and instantaneous speed.
  • Interpret position-time graphs.
  • Calculate the speed of an object using slopes.
Acceleration

In this lesson students will learn to:

  1. Identify changes in motion that produce acceleration.
  2. Describe examples of objects moving with constant acceleration.
  3. Calculate the acceleration of an object, analytically, and graphically.
  4. Interpret velocity-time graph, and explain the meaning of the slope.
  5. Classify acceleration as positive, negative, and zero.
  6. Describe instantaneous acceleration.
Splash and Learn

Students will utilize their knowledge about projectiles to devise a method to launch a water balloon so that it lands on a 1 meter square cloth target at least 25 meters away. If they hit the target with the balloon (not just splash a few drops on it), they receive extra credit on the lab.

Distance and Displacement.
  • In this lesson students, will be able to identify frames of reference and describe how they are used to measure motion.
  • Identify appropriate SI units for measuring distances.
  • Distinguish between distance and displacement.
  • Calculate displacement using vector addition.
Linear Motion

The lesson explores ways for students to describe linear motion and investigate relationships between the velocity, acceleration, and the concepts of vector/scalar quantities.

Momentum and the Law of Conservation of Momentum: A Student-Centered Lesson

This is a largely self-paced unit for students to learn the basics of Momentum as well as the Law of Conservation of Momentum. Students complete two investigative exercises (one hands-on, the other virtual). They then are directed to read a website (or a textbook could be substituted) and take notes with the teacher"s support as needed. After taking their own notes, students complete a worksheet to practice calculations involving the Law of Conservation of Momentum. At the end of the unit, students take a traditional summative assessment with True/False, multiple-choice, and fill-in-the-blank questions along with a calculations section. Note that this lesson only covers the basics of linear momentum and does not include impulse or angular momentum.
