3NT kiddos learnt about simple machines in Term 3. Created station-based learning activity for lesson. Each station focus on a key learning point.

They had made their own toy car in previous lesson. At this station, the kids compare the force needed to move 50g weight in a carton with wheels and without wheels.

Here, the kids adjust the slope of the box to compare the force needed to move the weight as the steepness of ramp change.

Another comparison type of station. Comparing force needed to move a weight across sandpaper and concrete floor.

The last one is their favourite! They make their own pulley and fasten a magnet on one end of the string. Then they adjust the pulley to pick-up as many paper clips on the table top. Kids do enjoy games and challenging each other, so they love this station the most!
