The concept of more or less is one that needs to be mastered prior to learning other concepts such as quantitative analysis, addition, or subtraction. This activity provides several ways to teach learners with low or no vision to...

This only has three problems, so consider simply projecting it and doing it with the whole class. First, they examine two baseball bats and circle the shorter one. Then, they consider which of two containers will hold more. Finally,...

Expand the the comparative language of young mathematicians with a hand-on weight measurement activity. Working independently or in pairs, children compare the weight of large wooden blocks to various other classroom objects, recording...

In this mathematics worksheet, 1st graders identify which items pictured weighs more or less than a pound. Then they circle the objects that weigh more and place an X on the object that weigh less than a pound.

Primary learners participate in activities that help them explain how different things are measured. They create their own access number chart.

Can you feel the weight of the air on your shoulders? Your classes may not believe that air has weight. A straightforward experiment asks individuals to weigh a bottle before and after adding air. Their results may surprise them!

Upper graders experiment with measurement. They estimate the length, volume, and weight of various objects, then rotate through stations making predictions concerning measurements and then testing their predictions.

Here are 22 problems on 4 pages intended to provide practice in calculating mass. Learners determine the differences in weight, fractional equivalents of given quantities, and determine which item is heaviest or lightest. The problems...

Students order their classmates from smallest to largest foot length.  In this ordering their classmates from smallest to largest foot length lesson, students trace each of their classmates foot.  Students read a story called,...

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Who is two years younger than Meg? Who is older than Paul, but not Kinta? Scholars practice reading tables as they answer comprehension questions based on three sets of data. First, they examine a table depicting ages, then favorite...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Rainy day schedule doesn't mean you can't stay fit! Use a collection of indoor physical activities during periods of inclement weather, substitute teaching days, or for those afternoons when your class just wants to move around!

Here's an interactive with real potential ... potential energy, that is! Scholars analyze scenarios, then rank objects in order of greatest to least kinetic energy, potential energy, and speed. The interactive provides support materials,...

Students confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Some consider physics the branch of science concerned with using long and complicated formulas to describe how a ball rolls. This presentation, while long, is not complicated, yet it covers rolling, falling, and more. It compares vectors...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

The title of this article from the New York Times is "The Cult of Physicality". So are you wondering what this article might be refering to? Well, then read on and find out more about what some call extreme fitness. There is a...

Students discuss how weight is directly related to gravitational force on a planet. Students then choose Space Traveler as companion and compute how much their guide weighs on various planets, based on each planet's relative surface...

Students build a vehicle following technical drawings. They set up a system to pull the vehicles. Students compare and discuss how the motion of the vehicles changes more or less weight on a string is used to pull them.

Getting the right measurements can save a lot of time and money in the real world. Learners are introduced to unit conversion and how to accurately go from one unit to another. The first pages are notes and then the packet finishes with...

Extensive background material, clear objectives, and more are provided to help you teach an introduction to nuclear power. Learners will be able to explain how nuclear power is generated and how it compares to coal-created power. Provide...

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...
