# Preschool Balance Scale Activity: What is Mass?

Make your own balance scale to compare household items and measure them by mass with this preschool balance scale activity!

This preschool balance scale STEAM activity is so simple to set up! It’s also a great activity to inspire scientific learning.

I love preschool aged kiddos because they are super curious about how things work. This balance scale activity is a great activity to introduce scientific, mathematical, and engineering concepts.

Our goals were to make observations about the physical properties of each object, measure and compare the mass of each object, and measure the mass of each object with a non-standard unit.

To encourage the practice of observing and recording results, I came up with a simple Balance Scale workbook that an adult can help with.

## Why STEAM Activities?

STEAM is the abbreviation for Science, Technology, Engineering, Art, and Math.

STEAM, like STEM, is an integrated approach to learning that encourages learners to make connections between the concepts they are learning and how they apply them to real-world problems.

STEAM helps students ask questions, problem solve, think creatively, and produce innovative solutions. Many schools have adopted STEAM learning activities into their curriculum, but it’s never too early to start building critical thinking skills.

We love to learn through play at our house and have a blast doing activities for toddlers all the way to tweens!

Looking for some more hands-on activities that incorporate Science, Technology, Engineering, Art, and Math (STEAM)? Then you have to check out STEAM Kids!

This book features more than 50 hands-on activities that are organized into easy to implement categories, so you know exactly what concepts your kids are learning!

## Key Simple Machines and Mass Activity Terms

Weight is the measure of the pull or force of gravity on an object and mass is the amount of matter in an object and a measure of the force needed to accelerate it.

A lever is a simple machine that is made of a fulcrum and beam with an input force and an output force. A balance scale is a Class 1 type lever designed with the fulcrum in between the load and the effort.

The fulcrum is the point on which a lever moves. Load is the mass the lever is trying to move, while effort is the force that moves the lever.

Think about a seesaw. The fulcrum of a seesaw is the center point on which the board balances. The load would be the amount of mass on one end that is moved by the effort that moves the seesaw.

This activity also explores key terms such as equal, balanced, more than, less than, compare, heavier, and lighter.

## Preschool DIY Balance Scale Activity Supplies

• Shoebox lid
• Can of soup
• Marker
• Tape
• 2 plastic cups
• Pencil
• 15 pennies
• 10 nickels
• Small objects (gems, rocks, building bricks, blocks, shells, dice, etc.)
• Optional: Magnets (We use these magnets for all of our crafts and activities.)
• Free Balance Scale Workbook (grab this at the end of the post)

## Preschool Balance Scale STEAM Activity

Begin with a handful of different sized objects. Write the objects you are using in your Balance Scale Workbook.

Next, use physical properties to sort your objects from largest to smallest. Record your objects in your workbook.

Build a balance scale with a can of soup (you can also use a pencil), a shoebox lid, tape, and a marker. The can of soup will be your fulcrum.

Tape the can of soup to a surface, so it doesn’t roll. Balance your shoebox lid on top of the soup. Do not use tape to secure the lid to the can.

Place two empty cups on either end of your shoebox lid. Make sure that the cups are all the way to the end on either side. Make sure that the cups are balanced before beginning.

I used magnets on the inside and underneath my shoebox to secure the cups in place. Make sure to balance your lid if you chose to add magnets to your cups.

Use your balance scale to measure your different objects and compare them to one another. Record your results in your Balance Scale Workbook.

Did the order of your items change from Step 1?

Use pennies to measure the mass of your objects. Make sure to record how many pennies each object weighs in your Balance Scale Workbook.

Invite your child to explore independently. Use the balance scale cards in your workbook to help guide them.

## Questions to Discuss During Your Balance Scale Activity

• Does the size of an object always determine its mass?
• Do you have a small object that has more mass than you expected?
• Do you have a large object that has less mass than you thought?

## Levers in Our Everyday Life

Some levers in our everyday life include: seesaws, scissors, tweezers, crowbars, bottle openers, and hammers!

## Connect this Preschool STEAM Activity with other STEAM Buckets

Check out these STEAM extensions!

### Science

Pair this with a density experiment and place each item in a density tower to compare the density of each item. Larger items don’t always have more mass than smaller items.

### Technology

Use the K6 Think Central Math Tools balance scale to explore more objects.

### Engineering

You built a balance scale, which is a lever. This is a way to introduce simple machines to preschoolers. Discuss other types of levers. Move your fulcrum to one side of your lid and show how you can lift heavier items by using this type of lever.

### Art

Use the Balance Scale worksheet provided to write the names of your objects. Draw a picture on the back to show the size of each item in Step 1.

### Math

Graph your results. Use one color for pennies and another color for nickels. Discuss what you see.

We love incorporating books into our activities. Here are some great books about mass and simple machines to read with your activity!
