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...

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

Give math vocabulary instruction a boost with a set of flash cards covering terms such as centimeter, pound, and thermometer to name a few. Word cards are typed using a bold-style font, and correspond to picture cards that...

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...

In this force activity, students answer short answer questions about pushing and pulling different objects. Students complete 15 questions.

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...

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...

Bagging groceries is a skill that can help learners with visual impairments understand organizing, problem solving, and weight discrimination. In addition, it is also a wonderful job skill. Help learners as they determine how to bag...

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 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...

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...

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...

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.

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).

Students identify comparatives and superlatives. Students read article on comparatives and superlatives. They explore spelling patterns. Students rewite adjectives to form comparatives and superlatives and complete a worksheet.

First graders measure weight and capacity. In this measurement instructional activity, 1st graders explore visual examples of weight and capacity comparisons. Students also practice solving problems that their instructors model.

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.

Math comes alive in this interactive lesson, which prompts learners 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...

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.

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.

Students are asked what activities or things that they do each day. They are then asked do you do that in the morning, afternoon, or night? Students are then asked which of those things do you do first, second, third, and etc.

This presentation starts with safety warnings for an experiment. Students will be introduced to the reaction that happens when magnesium is burned, the chemical background and the energy changes. Excellent examples and labeled reactions...

Circular motion can make you loopy! On this physics worksheet, learners practice solving problems regarding centripetal force, rotational period, speed, acceleration, and more. A flying aerobat and a couple of amusement park rides make...

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...
