Properties of Fluids
Enduring Understanding: Fluids
exist in both liquid and gas states and are governed by very specific
properties, including viscosity, density, buoyancy and pressure.
8-3-01 Use appropriate vocabulary related to their
investigations of fluids.
Include:
fluid, viscosity, flow, density, particle theory of matter, buoyant
force,
pressure, compressibility, hydraulic, pneumatic.
8-3-02 Distinguish between fluids and non-fluids.
8-3-03 Explore and compare the viscosity of various liquids.
8-3-04 Identify products in which viscosity is an important
property, and evaluate
different
brands of the same product, using the design process.
8-3-05 Plan and conduct experiment to determining factors that
affect flow within
a given
system.
8-3-06 Measure, calculate, and compare densities of solids,
liquids, and gases.
Include:
different amounts of the same substance, regularly and irregularly
shaped
objects.
8-3-07 Illustrate, using the particle theory of matter, the
effects of temperature
change on
the density of solids, liquids, and gases.
8-3-08 Compare fluids of different densities to determine how
they alter the
buoyant
force of an object.
8-3-09 Recognize that pressure is the relationship between
force and area, and
describe
situations in which pressure can be increased or decreased by
altering
surface area.
8-3-10 Explain, using the particle theory of matter, the
relationships among
pressure,
volume, and temperature of liquid and gaseous fluids.
Hydraulics and Pneumatics
Enduring Understanding: Fluids transmit force in a predictable manner that can be utilized by
humans, including hydraulic (liquid) systems and
pneumatic (gas) systems.
8-3-11 Compare the relative compressibility of water and air,
and relate this
property to
their ability to transmit force in hydraulic and pneumatic
systems.
8-3-12 Identify a variety of natural and constructed hydraulic
and pneumatic
systems and
describe how they function.
8-3-13 Compare hydraulic and pneumatic systems, and identify
advantages and
disadvantages
of each.
8-3-14 Use the design process to construct a prototype that uses
a pneumatic or
hydraulic
system to perform a given task.

In addition to hard-copy resources I have available in the school and from colleagues, I also started to organize some online resources to supplement our classroom activities. Here are the resources I found, organized by the themes I stated above. For each one I've included the title, a very brief point about what it includes, and the link.
Properties
of Fluids
The Density Song
- Musical review option
- Broadway style song
Can I Pour Air Demonstration - Discrepant
Event
- U of M Lesson
- Shows that fluids are liquids and gases
Fundamentals of Fluids
- Articles, quizzes, interactives, videos
Buoyancy Demonstration
- U of M Lesson
- Would need to be a large-group activity
lesson
Buoyancy Virtual Lab
- Great lab that can be used on iPads or as
a large-group activity
- Includes procedural questions
Viscosity of Liquids Video
- Might be good for center activity, have
students list items from
least to most viscous
Viscosity Explorer
- Virtual lab
- Chose from water, olive oil, ethanol,
corn syrup, honey &
factors in temperature http://www.planetseed.com/flash/science/lab/liquids/visco_exp/en/viscosity.htm?width=620&height=500&popup=true%20
Wonderville Pipeline Inquiry Project
- 5 Point experiment, good for group
activity
- Would be great for when there is a sub
Pressure on Gas Virtual Lab
- Great lab that can be used on iPads or as
a large-group activity
- Includes procedural questions
- Density Tower
with 9 different liquids
Hydraulics
& Pneumatics
Hydraulic & Pneumatic Part 1
- Good video explaining both systems
- 6 minutes
Forces & Fluids
- Textbook chapter section
- Good teacher resource
Mega Machines
- Game with hydraulic machines
- Enrichment activity if students are done
early
Pneumatic Air Nailer Lab
- Article about nail guns to help with the
lab
- Lab will take place in the wood shop

I hope you find these resources as awesome as I do!
If there is something you think I should add to my list let me know, I'd love to hear about the awesome things you are using with your class :)
Thank- you so much for posting all these links! I was at a loss when I came to this section of my unit and was having no luck with generic website searches for student friendly sites - and then I found yours! Thanks again for sharing.
ReplyDeleteGreat Stuff! Your resources have been a huge help in planning my next unit!
ReplyDeleteI'm a student teacher from winnipeg and I came across your blog off the first page of google when searching for hydraulic/pneumatic lesson ideas!
ReplyDeleteThank you so much for posting this, very helpful!
Excellent links. If only my school had internet.
ReplyDeleteThanks so much for this post. I am student teaching and this will help me sooooooo much with lesson and unit planning as I was struggling how to make this entertaining and finding resources on the internet.
