This week Room 7 got to visit Mrs Dell in Room 6. We read the book The Very Busy Spider and then we got to make a spider that moved as you pulled on the string.
We needed the following materials:
• straw
• tape
• String/wool
• spider template
This was all about friction. Friction is the force that holds the spider up. Friction works against an object that is moving. When you pull down on one of the strings, it moves through the straw. The surface of the straw grips against the string, stopping the basket slipping down. The rougher the two surfaces are, the greater the friction.
