Physical Quantities: Scalar and Vector – Fundamentals

WATCH THE VIDEO OF THE COMPLETE ACTIVITY

⚠️ This material is an adapted Physics activity designed to teach Scalar and Vector Physical Quantities in a visual, progressive, and accessible way for students who are developing literacy skills or need additional support with reading and interpretation.

Number of questions in the activity:

6 adapted questions + complete answer key, distributed across 3 activity pages.

The sequence begins with a simple situation involving the mass of a backpack, progresses to distinguishing between scalar and vector quantities, explores the elements that characterize a vector, presents examples involving mass, time, temperature, energy, force, and acceleration, examines the combination of forces acting in opposite directions, and concludes with a practical direction and orientation activity on a grid.

Target audience:

The material can be used in middle school and high school, depending on the student’s curriculum adaptation needs. The learning objective covered is Scalar and Vector Quantities.

It may especially support students with mild to moderate Intellectual Disabilities, difficulties with abstraction, reading and interpretation difficulties, students developing scientific literacy, and those who have difficulty distinguishing scalar from vector quantities.

It is also suitable for students who need to develop spatial orientation skills, since the final question uses cardinal directions and movements on a grid to make direction and orientation more concrete.

Content covered:

The activity explores the difference between scalar and vector quantities. Through the examples provided, students learn that quantities such as mass, time, temperature, and energy can be characterized by a value and unit, while vector quantities, such as force and acceleration, also involve information related to orientation.

The three elements used to characterize a vector quantity are also covered: magnitude, direction, and sense. These concepts are later reinforced through a situation involving two opposing forces and a route guided by cardinal directions.

Important information for teachers:

In the first question, Lucas places his backpack on a scale, which reads 6 kg. From this concrete situation, students identify the mass of the backpack as a scalar quantity. The image allows them to connect the object, measurement, value, and unit before classifying the quantity.

In the second question, students complete a “Find the Odd One Out” activity. They are presented with mass, time, force, and temperature. Since three are scalar quantities and only one is a vector quantity, students identify force as the one that differs from the others.

In the third question, students complete the definition of a vector quantity using a word bank. They recognize that a vector quantity has magnitude, direction, and sense, becoming familiar with specific Physics vocabulary without having to produce the entire answer independently.

In the fourth question, six quantities are presented with visual representations: force, time, temperature, acceleration, energy, and mass. Students select only the scalar quantities: time, temperature, energy, and mass. The images help students recall the meaning of each term while classifying them.

In the fifth question, Ana and Bia exert forces in opposite directions on a toy cart. Ana applies 5 N to the right, while Bia applies 8 N to the left. Students observe the situation and trace the information describing the resultant force: magnitude of 3 N, horizontal direction, and sense to the left. In this way, the elements of a vector are applied to a concrete situation rather than appearing only as an abstract definition.

Finally, the sixth question presents a grid containing a boy, obstacles, a waterfall, and a compass rose. Starting from the red point, students draw the route by following instructions such as 4 squares East, 2 squares North, 6 squares East, and 1 square North until reaching the destination. This activity provides practical experience with the ideas of how far to move and which way to move.
