Practice the comparison words lighter, heavier, longer, shorter, smaller, and bigger using this visual chart. For each set of three objects, pupils order them according to one of these terms. The six terms are illustrated...

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...

A variety of concepts are covered in this PowerPoint which gives the main engineering points of different aircraft types. Each slide details the engineering behind non-rigid and rigid categories of lighter or non-lighter than air...

Students observe several rocks and try to tell by looking and feeling, which rock is the heaviest, and which is the lightest. They take turns putting two rocks at a time in the balance scale to see which rock is the heaviest, then they...

In this heaviest object instructional activity, students check the object in a set of 2 that is the heaviest, 6 sets total. Answers are included on page 2.

Students explore the concept of air density. In this air density instructional activity, students fill balloons with helium and carbon dioxide. Students determine which gases are heavier or lighter than air.

Math comes alive in this interactive lesson, which prompts students to weigh small classroom-available items (erasers, pencils, rulers) as well as more obscure items that would need to be provided (a basket, a small toy car). Students...

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 pounds and ounces worksheet, students read about weighing items, and about the words "heavy" and "light." Students circle words that go with pictures of heavier/lighter things. Houghton Mifflin text is referenced.

Comparing college football teams, Division I is said to have heavier lineman than Division III. Your mathematicians are given data from two different divisions and will have to interpret a dotplot and calculate the difference in weight...

If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the...

In this friction instructional activity, students test heavy and light objects to see if the more friction of the heavier object makes it easy or harder for it to slide. Students also answer 5 questions.

Which is heavier, a ladybug or a ship? Learners will have fun with this weight comparison worksheet, that uses visuals to help them determine which is heavier or lighter. They complete two comparisons for each. Lastly, they examine four...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students test whether gravity makes heavier things fall faster than lighter ones.

In this measurements worksheet, students practice the skill of choosing objects that are larger, smaller, taller, heavier and/or lighter than other objects. Students choose the multiple choice answer that best answers 7 questions.

Young scholars participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

In this weight comparisons worksheet, students circle the picture of the heavier object in each set. Students underline the picture for the lighter object. Students finish by drawing items on the balance that have the same weight.

Sixth graders weigh regular and diet soda to see which one is heavier and therefore which one contains more sugar. In this soda lesson plan, 6th graders discover that regular soda contains more sugar because it weighs more. 

Students work together to discover the relationship between the angle of catapults and the flight of different objects. They discover the heavier the object the more force is needed. They examine how engineers use this information to...

First graders experiment with different sized balls and an incline plane to study how a heavy object push a lighter object. They examine the safety message of this activity by showing their drawings of the crossbuck sign.

Students discuss, examine and appreciate the science and inspiration of flight. They study the terms and mechanics of powered flight and demonstrate that the heating of air makes it lighter and therefore rise. They discuss and...

Students compare, order, and measure objects. In this measurement activity, students are assessed on their ability to order, compare, and measure objects. This is an assessment only activity and does not include instruction.

Enhance your math lesson with a series of pictures that illustrate different math concepts. The vocabulary includes a variety of ideas and pictures including fractions, ordinal numbers, picture graphs, and number lines.

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