Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Students titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Learners comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson plan which provides great demonstrations and hands-on...

Young scholars learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast plate...

Find the mass, volume, and density in five different equations with a straightforward worksheet. Each equation prompts kids to work through word problems of varying difficulty and to find the necessary measurement using different formulas.

In this density activity, high schoolers are given 11 problems and they determine the density of the substance, the mass of the substance or the volume. They write the equation they use to solve the problem, they show their work and they...

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...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Students investigate unit conversion.  In this unit conversion instructional activity, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and...

In this chemistry overview worksheet, students calculated the volume of different gases and liquids given in a word problem. Students had to calculate the molecular mass and write the empirical formula and the molecular formula.

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online worksheet. Your class will determine the volume of water, the shape of water and the shapes of matter.

In this ideal gas law worksheet, students solve eighteen problems using the ideal gas law to solve for moles of gases, temperature of gases, pressure of gases or volumes of gases.
