This week, we have been exploring the effects of friction on how far something can move.

We measured how far paper “Dragon Racers” moved on different surfaces when we moved them with air. Most groups discovered that the more bumpy or textured a surface is, the more friction is caused and the Dragon Racer moved a shorter distance.

     

“Surprisingly, my team got 790cm on the carpet” HA

“Our Dragon Racer went a lot further on the table top because it has a flat surface” LR

“I didn’t think it would go that far on the aluminium foil.” AM

“We placed the Dragon Racer upwards so it would go further than facing downwards.” IR

“I made a prediction about one of the surfaces and in the end my prediction was right.” SS

“I thought the dragon wouldn’t go far on the rug but it did.” IM

“I was very surprised about two of the surfaces.  the rug only went 25cm and the textbook was the furthest.” FS

“Surprisingly it went really far on the tin foil and I thought it wouldn’t go far” FF
