Q1. What is the difference between non standard and standard measurements, according to Chapter 10 of Class 6 Science?
Non Standard Measurements - When an individual measures an object keeping into account the length of the arms, hands or fingers , this measurement is never reliable and accurate because the length of one’s hands, arms or fingers are different compared to the other individual. These methods therefore become the Non standard measurements.
Standard Measurements - When the measurements are the same all over the world for the same object, then that is referred to as the standard measurements.

Q2. What are the different types of motions, according to Chapter 10 of Class 6 Science?
Rectilinear motion: This type of motion refers to the motion in a straight line. For example, the vehicles moving in a straight line on the road or the athletes running straight on the track.
Circular motion: Circular motion refers to the movement of any given object in a circular path along the circumference of the circle. For instance, if one ties a stope to a string and rotates it, the motion thus produced is the circular motion or the fan's rotation.
Periodic motion: When an object repeats its motion after a given time, it is termed the periodic motion. For instance, the motion produced by a pendulum.
Q3. What is the right procedure in the measurement of a length with a broken scale, according to Chapter 10 of Class 6 Science?
To measure the length of any given object precisely, the following steps are to be followed:
The first step involves the placement of the scale in contact with the given object.
While taking the measurements, starting from the zero mark is to be avoided.
For instance, the full mark on a scale, 1.0 rather than 1.7, is to be used.
The reading of one particular end is subtracted from the reading of the other end. For instance, if the reading at the starting, placed from the mark 1 cm, ends with the reading of 5.5 at the other end, the length of the object will be 5.5-1.0= 4.5
Another important point to be remembered while measuring an object is that the position of the reader’s eye also matters. Therefore the position of the eye should be exactly above the point where the measurement is to be taken.
Q4. Explain when there is a combination of two or more motions, according to Chapter 10 of Class 6 Science?
In some cases, it is seen that the object's motion might include the combination involving two or more motions. Some examples of it are as follows -
A rotating ball in motion on the ground makes it clear that because the ball is rotating, it follows a rotatory motion, but it is also moving in a straight line. Thus it can also be said to execute a rectilinear motion.
The motion of a vehicle on the road: the vehicle's wheels can be seen to perform the rotatory motion, but as the vehicle is moving in a straight line, it can also be said to perform the rectilinear motion.
Q5. Is it important to read the activities that are given in Chapter 10 of the Class 6 Science book?
The Chapter 10 of Class 6 Science CBSE textbook provides different sections concerning the activity to the topic being taught. If practiced, these activities will help students understand and learn the concepts in a new and better light. These activities are extremely easy to follow and require everyday items for their function. Therefore, it is easy for students to use the items and practice them to have a fun experience and the learning process.
