Simple Balancing is an excellent and fun science project.
You will need:
2 light weight containers that are identical (butter tubs work well)
a hole punch or something that can poke holes in the containers
6 pieces of yarn or string – cut the same length
and a hanger
Carefully punch 3 holes equal distance around the rim of each container.
Thread the yarn thru each hole and tie in a knot – leaving equal amounts of yarn on each container.
Tie and knot the three pieces onto the hanger – do this with both containers – one on each side of the hanger.
This will create a simple balancing scale.
This will create a simple balancing scale.
Hang the scale from a hook or door knob ( the scale cannot be leaning against anything for more accurate results).
Once the scale has been completed – have the students compare objects weight.
Which item is heaviest? Lighter? Weighs the same?
Also use 'prediction' as well. Graphing the results adds another dimension to this fun activity.
