Looking for a fun valentines day science activity for February? This liquid density experiment is sure to be a hit with your toddler, preschool, pre-k, kindergarten and elementary age students in first grade, 2nd grade, and 3rd grade students. Children will be amazed as they watch the layered liquids stack up in pretty valentine’s day colors for an EPIC valentine science experiments that kids will remember fondly. This valentines day activityis a great way to teach kids what is density for kids with a fun, hands-on, pretty density experiment.

## Valentines Day Science

This density science project is a fun way for preschoolers, kindergartners, grade 1, grade 2, grade 3, and grade 4 students to explore density for kids! This layered liquids activity allows to explore how various liquids with different densities behave when placed together and what it really means. This density science is filled with pretty red, pink, and white layers to make a pretty and fun science experiment for Valentines day. Use this valentines day activities at home, in the classroom, or as part of your homeschool science lesson.

## What is Density for Kids

Basically density means how much space an object or substance takes up in relation to the amount of matter in that object. Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density. So you can have 1 cup of water and 1 cup of corn syrup. Even though they are both the same measurement, the corn syrup has a higher density because the molecules are closer together. You can visually see then when you pour them both out. The corn syrup goes out slowly because it is a thicker fluid.

Simply put, density is a measure of how close together pieces are. If they are close together, the object is dense. If the pieces are far apart, the object is less dense. An object with a low density has more space for air. In the picture above I have a box with just a couple lego pieces and a box with more lego pieces. The one to the right is more dense as their are more lego pieces in the same space. Make sense?

## Valentines science experiments

For this fun density experiment for kids we will explore how various common liquids have different density. Because they have different densities they will sit on top of one another. This is super cool and pretty simple to do if you follow our directions and go slowly step-by-step. Before we get started, please DO NOT SHAKE or stir your experiment! While the substances would eventually seperate back out by density, the food coloring we are using for the demonstartion would not come out so pretty.

## Valentine’s day science experiments

Put the following common household ingredients in a tall clear container. It can be a vase, tumbler, empty starbucks frapachino cup if that’s what you have on hand.  The quantity or how much of each layer depends on how big your container is. You want to see the layer clearly so aim to get each layer about 1-2″ deep. Poor SLOWLY each layer so they trickle down the side of the jar or use a turkey baster to slowly put the material in the next higher opening.

So in order add the following:

• Honey (mixed with red, pink, or purple food coloring)
• Corn Syrup
• Maple Syrup (mixed with red, pink, or purple food coloring)
• Hand Soap
• Water (mixed with red, pink, or purple food coloring)
• Vegetable Oil

## Valentines Day Activities for Kids

Then add random items to see where they land density wise in your jar. I suggest trying things like a penny, heart, pompom, marble, conversation heart, etc. Have children make predictions (or a scientific hypothesis) of which items will sink down further and to what layer they will fall.

## Density experiments

• Will the light pom pom sink further down than the penny?
• Do you think the items will stop at different layers?
• Will any of them fall to the bottom honey layer?
• As the items drop will you notice any change in the layers?
• Do you think the layers will mix together throughout the experiment

## Liquid density experiment

At the end, you can try to mix the substance with a long wooden spoon and then wait (hours) and see if it seperates back out. What did you notice? Did it all seperate back out? Did the colors end up exactly the same as they were before? Why do you think that happened?

## February Activities for Kids

I suggest using these scientific method worksheets to have kids make predictions, observations, and conclusions. THey can either write or draw their predictions and draw what they observed with each of the layers.
