How do you calculate your Body Mass Index, and why is this information a valuable indicator of health? Class members discover not only what BMI is and practice calculating it using the height and weight of six fictitious individuals, but...

Youngsters test magnetic strength by measuring the mass of paper clips that they "hook" with a magnet. Your first and second graders should love the hands-on activities associated with this plan. The reproducible materials are quite good...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

Study the difference between mass and weight. Your math group will compare the weight of an item to the amount of space that it uses. They'll then use conversion factors to find the difference between kilograms and pounds. Essential...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Review questions like these can be used in your biology, chemistry, physics, or earth science classes! They assess scientists' understanding of laboratory measurement tools including graduated cylinders, thermometers, and balances. They...

Explore the mathematical relationship between a solvent and solute. Learners use technology to measure the cooling patterns of a solvent with varying concentrations of solute. Through an analysis of the data, pupils realize that the...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Learners list different uses for common scientific instruments. They identify appropriate instruments to measure length, temperature, and mass. Pupils are given a copy of the "Science Tools" task sheet, students place the correct number...

Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Third graders explore the relationship of mass to volume. In this physical science instructional activity, 3rd graders participate in an investigation with a several materials and measure the mass and volume using scientific tools....

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

Students explore the different arrangement of air molecules in high and low air pressure masses. They compare the temperature of high and low pressure masses and discover how a barometer works.

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

Students investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

Learners circulate through stations to determine the proper instrument to make a certain type of measurement. They must make measurements of mass, volume, length, area, electrical current, temperature and force.

Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Students are asked to estimate mass, length, volume, and area.

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

In this stoichiometry worksheet, students calculate molar masses, empirical and molecular formulas to solve 105 problems and short answer questions.
