Sweeper

To continue  our adventure with Lego our pupils regularly have lessons with bricks. Recently the 4^th graders have had to build a sweeper – a cart combined with a broom. To check if it works we spread out paper scraps on a table top. When we pushed the sweeper its blades opened out and spun. The table top was clean again.
