Please proceed outside to be sorted into your activity group.

Getting Started

Number off each member of your group of from 1 to 4 or 5

Number 1 will collect the dixie cup labeled 1 Number 2 will collect the dixie cup labeled 2 Number 3 will collect the dixie cup labeled 3 Number 4 will collect the dixie cup labeled 4 Number 5 (or number 1) will collect the clear

plastic cup and the worksheet.

Almost Ready!

The last thing you need to set up is the clear plastic cup.

Number 1 can pour the syrup in the dixie cup labeled 1 into the clear plastic glass.

**Be careful not to get too much on the sides of the glass**

A Quick Demo

When it is time, pour the rest of the liquids slowly down the side of the tilted glass as shown below.

Step 1

Think about what will happen if you pour the dishwashing liquid into the cup.

Sketch your hypothesis and explain briefly what you think will happen.

Tilt the cup on its side and slowly pour the dishwashing liquid (#2) into the cup.

What happened? Record your observation and sketch a picture.

Step 2

Think about what will happen if you pour the water into the cup.

Sketch your hypothesis and explain briefly what you think will happen.

Tilt the cup on its side and slowly pour the water (#3) into the cup.

What happened? Record your observation and sketch a picture.

Step 3

Think about what will happen if you pour the vegetable oil into the cup.

Sketch your hypothesis and explain briefly what you think will happen.

Tilt the cup on its side and slowly pour the vegetable oil (#4) into the cup.

What happened? Record your observation and sketch a picture.

The End Product

You will have 2 minutes to discuss in your groups what happened and why.

Select one person who will present your hypothesis to the class.

The Ingredients

Everything used was a liquid. Every liquid was different. Every liquid has a different density.

Density

Density is the number of individuals or objects in a specific area.

Example

High Density Low Density

Liquids Are Full Of Stuff!

Liquids are made up of tiny pieces called molecules. Some liquids have more molecules and therefore

have a higher density Some liquids have less molecules and therefore

have a lower density.

High Density

Low Density

Layered Liquids

Liquids with a lower density will ‘float’ on top of liquids with a higher density.

Which liquid has the highest/lowest density?

Corn Syrup

Dishwashing LiquidWater

Vegetable Oil
