Students use tables showing the ratios between ounces and pounds, grams and kilograms, and pounds and kilograms. They estimate whether an object should be weighed in ounces or pounds and whether an object should be weighed in grams or...

Second graders define "pound," estimate and compare weights, and classify objects as weighing more or less than a pound.

Third graders select appropriate units for measuring and solving problems in customary systems, identify equivalent measures within measurement system, and estimate, determine, record, and discuss weight using appropriate customary...

Students compare and contrast the terms "weight" and "mass". For this physics lesson, students observe an experiment in which objects are placed on a balance scale and weighed under different circumstances. Partners drop items and...

Fifth graders review the definition of mass and volume. They calculate and graph the density of various types of fruit while working in groups on a spreadsheet program. They look at how size of the fruit can be similar but the weight is...

Students use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...

Students find an object that they estimate weighs 20g and check estimates on the balance scales. They read the problem and work in pairs focusing their understanding on the size of grams.

Fifth graders use metric measurement to study the amount a bison eats. For this measurement lesson, 5th graders watch a video about bison and discuss the amount of food they eat. Students weigh their food trays at lunch and complete a...

Students and parents participate in a variety of activities designed to help them explore the similarities and differences of people. They design and wear masks, sort attribute blocks, read stories, discuss the rights and...

In this Earth worksheet, students read about Earth's gravity, the reason the Earth has seasons, and time zones. Then students complete 21 multiple choice, 2 true or false, and 1 short answer question.

Pupils classify, weight and organize items during this lesson. This lesson works great as or with an introduction of the Periodic Table of Elements.

In this word problem worksheet, students solve 1 word problem. Students determine the number of different size weights needed to make any combination of weight from 1 to 17 pounds.

Students solve equations of the form ax+b=cx+d and visualize the concept of "balancing" an equation.

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

Students collect data from measurements and weights for this experiment. In this algebra lesson, students analyze graphs they create form their data to find the expression representing the data. They label which graph provided the best...

Students complete measurement activities. In this measurement lesson, students watch online clips about measurements. Students view items and discuss taking measurements of them. Students discuss what units of measurement and equipment...

Students order five weighted plastic eggs in order from lightest to heaviest.

Second graders distinguish the difference between pounds and ounces and arrange manipulatives from heaviest to lightest.

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales...
