Measuring Mass with a Triple Beam Balance

#### Slide 1 -Tekstslide

Deze slide heeft geen instructies

Learning Objective
At the end of the lesson, you will be able to measure the mass of different objects in grams using a triple beam balance.

#### Slide 2 -Tekstslide

Explain to the students the main objective of the lesson and what they will be able to do by the end.

Classifying Objects
In this activity, you will be given a set of objects and asked to classify them based on their physical properties: Mass, Magnetism, Solubility, Density, Conductivity, and States of Matter.
1. Spin the wheel.
2. Collaborate and make an educated guess to classify each item based on the property of matter selected.

#### Slide 4 -Tekstslide

Engage students in a hands-on activity where they can practice classifying objects based on their physical properties. Provide a variety of objects with different physical properties for them to sort.

What is mass?
Mass is the amount of matter an object contains.

#### Slide 6 -Tekstslide

Introduce the concept of mass and its definition to the students.
What is mass?
A
The amount of matter an object contains.
B
The size of an object.
C
The weight of an object.
D
The color of an object.

#### Slide 7 -Quizvraag

Triple Beam Balance
A triple beam balance is a tool used to measure the mass of objects. It has three beams with sliding weights.

#### Slide 8 -Tekstslide

Explain what a triple beam balance is and how it is used to measure mass.
What does a sliding weight on a triple beam balance do?
A
Checks the temperature of objects
B
Measures the length of objects
C
Calculates the volume of objects
D
Adjusts the balance to determine the mass

#### Slide 9 -Quizvraag

Deze slide heeft geen instructies

How many beams does a triple beam balance have?
A
Two
B
Five
C
Three
D
Four

#### Slide 10 -Quizvraag

Deze slide heeft geen instructies

What is a triple beam balance used for?
A
Measuring the temperature of objects
B
Measuring the length of objects
C
Measuring the mass of objects
D
Measuring the volume of objects

#### Slide 11 -Quizvraag

Deze slide heeft geen instructies

Zeroing the Balance
Before measuring an object, the balance needs to be zeroed. Move all the sliding weights to the left until the pointer is at zero.

#### Slide 12 -Tekstslide

Demonstrate how to zero the balance before taking measurements.
Where should the sliding weights be moved to zero the balance?
A
To the center
B
To any side
C
To the left
D
To the right

#### Slide 13 -Quizvraag

Deze slide heeft geen instructies

What needs to be done before measuring an object?
A
B
Resetting the pointer
C
Calibrating the scale
D
Zeroing the balance

#### Slide 14 -Quizvraag

Deze slide heeft geen instructies

Placing the Object
Carefully place the object on the pan of the triple beam balance, making sure it is centered.

#### Slide 15 -Tekstslide

Explain the proper technique for placing an object on the balance.
Balancing the Beams
Start by sliding the largest weight on the beam until the pointer drops below zero. Move it back slightly until the pointer is just above zero.

#### Slide 16 -Tekstslide

Guide the students on how to balance the beams using the sliding weights.
Continue adding smaller weights one by one until the pointer is perfectly balanced at zero.

#### Slide 17 -Tekstslide

Explain the process of adding smaller weights to achieve balance.
Read the mass by adding up the values on each beam. The mass is the sum of the values shown on the beams.

#### Slide 18 -Tekstslide

Teach the students how to read and interpret the mass measurements on the triple beam balance.
How do you read the mass?
A
By dividing the values on each beam
B
By adding up the values on each beam
C
By multiplying the values on each beam
D
By subtracting the values on each beam
