话题:滑滑梯背后的科学小知识
难易度:☆☆☆☆)
Slides are simple but always fun.All you need to do is to climb up to the top and slide down.But
do you know that there is science behind this simple playground equipment?
DYou climb up the slide and sit down.
You are ready to go.Are you sliding down?No,not yet.Things
stay still(静止的)unless something makes them▲.Itis
Newton's first law of motion(牛顿第一运动定律).So you have
to give yourself a push to start the journey.
2 Now you are sliding down.
3
Of course you are sliding fast.But when two things rub (
against each other,they cause friction(摩擦力).So,there is fric-
tion during the slide.Without friction,you will slide down
much faster and won't stop by yourself.That's dangerous.

话题:拔河游戏的科学原理
难易度:☆☆☆☆☆)
As we know,playing tug of war can help build your strength and raise your team spirit(
)But do you know that you can win the game even if you are not the strongest?Today we will ex-
plore it.You will find it more than a teamwork sport!
MATERIALS:
*At least two kids
¥A strong but soft rope
*A piece of tape(线带)
STEPS:
Put a coloured tape on the ground to mark the centre line.Then,divide the players into two teams
DAS1绿卡图书
and let them line up at opposite ends of the rope.Next,give gloves to players to protect their hands,
and remind()everyone to hold the rope.Then the players hold each end of the rope and wait for
the signal.When the judge()shouts "Go!",both teams will use big forces to pull the rope back-
ward.
MORE ABOUT THE GAME:
When playing,each player on each side of the rope takes
the normal force
four forces--the normal force(支持力)from the ground,tension,tension
friction
friction and gravity.If all forces add up to 0,the players won't
budge.And if they don't add up to 0,the players will be pulled
gravity
forward or move backward.Therefore,you don't have to be the strongest to win.It's about friction.
The bigger the friction is,the better the team can hold its position and pull the other team.
