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...

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

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...

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...

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.

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...

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...

In this friction worksheet, 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.

Students examine how salt water is more dense than fresh water through experimentation with eggs.

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

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 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 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.

Students conduct experiments in gravity by rolling objects down an incline and determining which ones roll slower than others. As part of the experiment, they design objects which will roll the slowest. Using digital movie cameras or...

Students are asked have they ever seen a pig? They are asked what are young pigs called? Students are given the Pigs Display Sheet. They see that on the sheet there are two piglets and their mother. Students are told that mother pigs are...

Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

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...

In this reactions worksheet, young scholars complete the given reactions by writing the products. Students do examples of composition, decomposition, single replacement, double replacement, and combustion reactions. This worksheet has 54...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Students conduct an experiment to discover what happens to air when it is heated or cooled, discover that wind moves from a high-pressure area (an area of sinking air) to a low pressure area (an area of rising air).

Here are some cross-curricular activities whil should help your kids understnad weight measurements and grammar. In this grammar and math lesson plan, learners read the book Skittles Riddles and practice counting and balancing skittles....

In this gases worksheet, students use the concepts of Graham's Law of diffusion to determine the velocity of gases and molecules. They describe kinetic energy and how it relates to the mass and velocity of objects.
