What are the three laws of motion? Nature, comprehension
Once children get an basic idea - they can start relating to the three laws and even start using them in their day to day language - like instead of saying, “I am resting” they can say, “I am in 1st law of motion”
Show this video
Whatever idea children get of the three laws - they distribute themselves in teams of 3 and go around and find ways in which they can demonstrate the laws (diff from what is shown in video) and more examples from their day to day life.
Some of the stuff can be purposefully kept to spark their thinking - or even distract it :-)
Stuff like toy truck with marbles, clock, water can and pipe, etc.
How in diff ways we can experience the three laws of motion?
When children see newtons laws in action in diff aspects of life - it gives them a more intuitive understanding of the same.

Watch the video. Based on your understanding together create a small dance drama illustrating the law of motions in space.
Child can google and watch more video of newton’s law in our life

PUSHING A CAR
Students can estimate the mass of a car by doing a simple experiment, under adult supervision of course. You'll need a car, level ground, bathroom scales, chalk, measuring tape, and stopwatches.
Have three strong students push the car. They will push the car from behind with the bathroom scales between their hands and the car. Their goal is to push the car with as constant a force—measured by the reading on the scale—as possible.
Another student sits in the driver's seat to steer and operate the brake. A fifth student sits in the front passenger seat and marks chalk lines on the ground at regular time intervals. A sixth student sits in the back, calling out "mark" every two seconds, after the "ready, set, go" has been announced.
From the changing distance traveled in each time increment, students can calculate the car's acceleration. You can find the speed over each interval, then look at how it changes over the set of intervals. With the force measured from the bathroom scales, and the acceleration, students can then estimate the car's mass using F=ma.
When finished, the estimate of the car's mass can be checked by looking at the posted mass on the doorframe of the driver's side, or by searching the Internet. Ask the students to brainstorm the various possible sources of error in the experiment. You can also film this for later video analysis.
They can also explore diff size of car or even two wheeler or a small cart and see how the same force produes diff acceleration because of diff weight.
How do we observe and or use the laws of motion? Nature, Logical, Synthesis
Making toys is both fun and exploratory. Lets just make more!
Make toys from these shown by Arvind Gupta all based on Newton’s laws.
Children can try and explain what they understand from each toy’s working
