In this Grade 2 science worksheet, children study how smooth and rough surfaces change motion. They fill in nine sentences about sliding, rolling, and stopping, then match four surfaces to their effects on a sliding toy. Grade 2 students predict which surface lets a block slide the farthest and explain why carpet grabs objects while a waxed floor lets them glide, linking friction ideas to their own experiences.
Style:
Force & Motion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. When two surfaces rub together, the force made is friction.
2. Rough surfaces usually have more friction than smooth ones.
3. A block slides farther on a smooth floor than on a rough rug.
4. Ice is very smooth, so it has very little friction.
5. Sandpaper feels rough, so it has a lot of friction.
6. Friction turns motion into heat, which is why your hands get warm when you rub them.
7. A toy car rolls the farthest on a smooth floor.
8. Shoes with bumpy soles grip the ground because of friction.
9. On a slippery floor there is less friction, so you may slip.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
ice rink
→ sled glides far
sled glides far
sandpaper
→ block stops fast
block stops fast
waxed floor
→ socks slide easily
socks slide easily
grassy hill
→ ball rolls slowly
ball rolls slowly
