Science: Waterwheel Procedure

Aim: To create a waterwheel
Teacher Resources from blog: Keynote titled, Whirling Water.

Student Equipment:

  • 4 wooden skewers
  • adhesive tape
  • piece of adhesive tac
  • 30cm of string
  • small weight – an eraser?

  1. Tape the 4 wooden skewers together lengthwise to create an axle.
  2. Tie the end of the length of string to the end of the axle where the skewers are blunt.
  3. Fix the adhesive tac to the other side of the axle where the skewers are sharp

Whirling Water

This week students worked in collaborative teams to create a waterwheel.

They had to identify one variable to change on their waterwheel and test which of the two models ran more efficiently (the time taken to wind up the string with the weight attached).

ENERGY cannot be created or destroyed: only transferred or transformed. Energy makes things work – it produces changes and makes things happen.

Energy is transferred when it passes from one object to another.

Energy is transformed when it takes on another form of energy.

Try to view the footage below from Group 5’s experiment. What is the variable they have changed/modified in their 2nd waterwheel?









Term 3 Science – We Need…..

To help resource the science lessons over the next few weeks, the grade six team are asking students to bring a few items from home. Remember, students will be working in small cooperative groups so only a few items per group is required, not 107 for the year level.

We need…

Battery operated torches (name item)

Battery operated childrens toys (name item)

Empty, unsquashed and rinsed out soft drink cans.

Thanks everybody. Please bring to school no later than 9am on Wednesday 17th July. Miss Convery will be so excited.
