Fun With Water

What are the rules you are expected to follow?

• Do not speak when the presenters or other classmates are talking

• Do not splash around in the water

• Do not put down other classmates for their ideas

• Run and tell your friends about your ideas

What is viscosity?

• How fast a fluid pours

• The measure of a fluid's resistance to flow

• Rubbing two objects together

• The way an object floats

What is friction?

• The speed of objects racing each other

• Forces being pushed together

• How an object drops to the ground

• The resistance of motion between two surfaces

Steps of the engineering design process in order

• Ask, imagine, plan, create, test

• Imagine, plan, ask, test, create

• Ask, plan, imagine, create, test

• Create, ask, plan, imagine, test

What is the engineering design challenge?

• Design a waterslide that has the most materials used

• Design a waterslide that looks the coolest

• Design a waterslide that will have a rubber duck flow down it the fastest

• Design a waterslide that has the most curves

What do you do during the imagine stage?

• Brainstorm how you are going to create your slide

• Think about what you are going to design

• Plan what you are going to build

• Figure out the materials you are going to use

What materials will be used?

• Rubber ducks, duct tape, pencils, paper

• Clear tape, rubber ducks, bendable pipe, paper towels rolls

• Rubber ducks, bendable pipe, bucket, duct tape, and wooden dowels

• Paper, wooden sticks, plastic tubing, bucket, rubber ducks

How long did you have to create your waterslide?

• 20 minutes

• 45 minutes

• 15 minutes

• 30 minutes

What kinds of fluids flowed down the waterslide?

• Water

• Oil

• Water and soap

• Honey

What can you do to improve your waterslide?

• Modify your design

• Use more materials

• Ask groupmates their ideas on how to improve it

• Get inspiration from other groupmates designs
