Year 5
Junior Secret Agents
In Science, Year 5 have completed secret agent tasks, thinking about
forces such as friction, gravity and air resistance.
The Junior Secret Agents are now experts at using Newton Metres to measure the friction when an item is dragged on different surfaces. They can use this knowledge to decide which is the best route to take if they need to get away from danger quickly.
To learn about gravity and air resistance, the Junior Secret Agents conducted experiments involving parachutes, including whether the weight of the object or the size of the parachute has a difference on it's speed.
We found that wood had the least friction and grass had the most friction, so we would choose to drag the object over wood.
The larger the parachute,
the longer it took to get
to the floor. This is
because of air resistance.
"Making the
parachutes
was really
fun." Toby
"I liked using the Newton
Metres and finding out the
measurements." Maddie
"I liked working as
a team." Annelise
"I really liked
becoming a Junior
Secret Agent and
wearing a badge with my
agent name on it!" Jake
