to touch the ground /

The lesser number of marbles, the longer the time taken for the parachute

to touch the ground /

When the number of marbles increases, the shorter the time taken for the

parachute to touch the ground /

When the number of marbles decreases, longer the time taken for the

parachute to touch the ground

[ 1 mark ]

Give your reason from the observation when three marbles are used ?

When three marbles are used, it reaches the ground at the shortest time

because the three marbles travelled at the fastest speed.

[ 1 mark ]

What conclusion can you draw based on this investigation?

The higher the mass of marbles, the faster time taken for the parachute to

touch the ground /

The lower the mass of marbles, the slower time taken for the parachute to

touch the ground
