Towards a just, equitable, humane and sustainable society

MOTION

Theme: Motion

Grade: 6,7&8

Students will learn about speed, velocity and acceleration while taking part in a running race.

“How fast can you run? What can you do to improve your speed? How fast must one run to beat the world record?” Compute speeds and interpret the data for improving speed performance. Learn all this and much more in the science class.

SPEED QUEST

This activity - a running race, has four segments to it.  (First -forward running, second - backward, third - hopping, and last - skipping).  Every student is involved in this activity as there are specialized teams needed for different responsibilities to conduct the race – the referees, the runners, the timers and the data gatherers.

Once the runners are timed in the race, compute the data for their speeds; find out who had the best average speed in each segment. Compare your speeds with the track record of athletes and see what it takes to beat their records. 

                        

MEASURING VELOCITY AND ACCELERATION ON A RAMP

Students will investigate how changing the height of the ramp changes the velocity of a ball, and the change in acceleration as it rolls down the ramp. Using a simple set-up of a wooden ramp and a ball, students will do an inquiry on how the motion of an object changes by varying certain factors. Allow them to design the experiment in their own way and gather data; this will give them a feel of how scientists design experiments. 

                   

APPLICATION IN REAL LIFE SCENARIOS

Using the knowledge of the relationship between speed, distance and time, students now use this to solve some real life scenarios. What is the fastest way to get to a place if you have to take multiple modes of transport? Who has the fastest average speed in two given scenarios? Find attached the worksheet with application-oriented problems

                 

MOTION GRAPHS

It is all about graphs - Depict the motion of an object; interpret the journey of a body from graphs and solve problems on motion using graphs. Here is a worksheet that has different problems on graphs. 

                     

VEHICLE SPEEDS

How do we decide which vehicle we want to buy? What are the factors that influence our choice – do we look for a fast vehicle with a powerful engine or one that gives us a good mileage and therefore consumes less fuel? Which of our choices are environmentally friendly? In this activity, students have to help buyers make responsible choices from the available bikes in the market. The factors they have to consider while making these choices are - the purpose, distance travelled, the mileage, speed etc. 

                       

REACTION TIME

We are all aware that over speeding increases the chances of accidents. 61% of the accident cases reported in India in 2016 were due to over speeding. Reaction time is an important factor in ensuring safe driving on roads. Reaction time is the time taken to make a decision and complete it. Find out how reaction time plays an important role when we make decisions on the road. Do a fun experiment and calculate your own reaction time. Is there a way you can reduce the reaction time?
