Apparatus Diagrams 4
Lab tools are cool! But, which one is the right tool for the job? Young scientists participate in a series of puzzles focused around some common lab equipment. Each puzzle requires learners to associate the tool with its image and a...

Introduction to Equations
Do your pupils truly understand inverse operations, or is their understanding a little backward? Scholars learn the meaning of an equation in the second instructional activity of a four-part Algebra series. A series of activities begins...
Curated OER
Newton's Second Law
Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

Are You Balanced?
Fifth graders discuss what it means to have balance in their lives. Individually, they are given a worksheet in which they list their activities and things they are involved in. To end the instructional activity, they place weights on...
Curated OER
Measures
Estimate and explore the length and weight of classroom items using standard measurement and scales. Students will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data chart....
PHET
Equality Explorer: Basics
Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Hydrogen-Oxygen Reaction Lab
High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Estimation Skills
Students use a balance scale with beans or seeds to estimate how many of them would weigh as much as a teddy bear counter. In this estimation lesson plan, students hold items to estimate.

Water Wonders
Students measure the amount of surface tension using a balance scale after a classroom demonstration students diagram the appearance of several liquids and label them.

How Heavy
Break out the balances for this primary grade lesson on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A graphic...

Longer and Heavier? Shorter and Heavier?
For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a...

Place Value Balancing Act
In this place value balancing act worksheet, 1st graders cut out the unit weights (100, 10, 1) and put them on four scales to make them balance with the weights given.
Curated OER
Balance or Tilt?
Sixth graders investigate the concepts of a variable, constant, expressions, and equations. They solve problems which require the interpretation of expressions in and out of equations looking for solutions. Students also use a balance...
Noyce Foundation
Boxes
Teach your class to think outside the box. Scholars use the concept of equality to solve a problem in the assessment task. They determine how to use a scale to identify the one box out of a set of nine boxes that is heavier than the others.

Not So Fair and Balanced: Analyzing Bias in the Media
Life is not always fair. Who's heard that before? This same concept moves to a larger scale using prejudice and bias. Pupils discuss where prejudice attitudes derive and how they develop throughout life. Reading comprehension...

Measuring Yourself Using the Metric System
Students measure using the metric system. In this geometry lesson plan, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.
Curated OER
Scales Problems
In this scales activity, students find the weight of the shapes on the scale by comparing it to the other side, and make up their own problems. Students complete 5 sets of problems.
Curated OER
Balanced Systems of Equations
Students solve equations. In this algebra lesson, students relate solving equations to a balanced scale. They add, subtract, multiply and divide on both sides to keep the scale balanced.
Curated OER
Measurement: Using the balance
Pupils use a balance and gram cubes to measure several different objects. They then record their results on a data chart and answer questions about them.
Curated OER
Balancing Act
In this balancing a scale worksheet, 2nd graders draw pictures to show how they can balance the scale using all four weights in five different scenarios.
Math Mammoth
Scales Problems
In this scales worksheet, students use addition, multiplication, and division to find out how much the shapes on the scales weigh. Students complete 8 problems total.
Balanced Assessment
House Plan
A short assessment has individuals determine the scale of a house plan. They use the scale to calculate the size of a door and window that need to be replaced, and then divide a bedroom in two, calculating the size of rooms created.
Balanced Assessment
A Loud Noise
In a scale measuring noise, an increase in 10 dB is a 10 time increase in power. Mathematicians examine the data graph of a real world exponential growth, with no logarithmic scale, and then create two equations relating the decibels and...
