To explore this concept we decided to test the density of some household liquids using something kids love density marble race.
Marble density race in different liquids for kids.
To do this density marble race experiment you will need.
Honey corn syrup and molasses.
Calculate the average velocity of the marble through the liquid.
The distance is the height of the liquid and the time will be the average time calculated in step 6.
Different liquids have different viscosities which means some liquids flow more easily than others.
With liquid density it can be equated to thickness of the liquid in it s simplest form.
Average time time 1 time 2 time 3 3.
Preparing your glasses for the marble race.
Timing the marble works best when using liquids that have a high viscosity ie.
The pouring test when you are finished dropping the marbles into the jars try pouring the liquids one at a time into another jar.
After i have introduced max to velocity and density with this fun marble race density became the subject of almost every conversation we have.
Measure down about 2 cm from the top of each glass with the ruler and mark the 2 cm location with the water soluble marker.
When honey is cold it may be very slow to flow because its viscosity is high there is more friction within the liquid that is slowing it down.

Viscosity races making science fun for kids says.
In this project we will determine the viscosities of 5 separate liquids.
In this week s chemistry themed family science activity families explore viscosity a property of liquids that is a measure of the friction inside the liquid.
Calculate the average time.
Repeat the experiment 2 more times for each liquid so there is enough data to take an average.
A kitchen science project by science buddies.

Have a helper hold two marbles level with the tops of two glasses.
The liquids we will test are corn syrup honey vegetable oil milk and water.

You will notice this.
Race your marbles to discover a liquid s viscosity which liquid has the highest viscosity.
July 1 2013 at 1 23 pm done a viscosity race before but this time i wanted to do it on a bigger scale and really get the kids.
