Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Upper graders experiment with measurement. They estimate the length, volume, and weight of various objects, then rotate through stations making predictions concerning measurements and then testing their predictions.

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

How much does the amount of gas in a sample affect its volume? Young chemists observe the number-volume relationship present in the gas laws through a colorful interactive. A handy meter records the volume as users observe a varying...

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Can your class tell the difference between a burette and a pipette? Develop their lab apparatus knowledge using a series of puzzles. The online activity associates the name, image, and sizes of burettes, pipettes, volumetric flasks, and...

Students determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the volume...

Students measure the rate of diffusion and to calculate the surface area to volume ratios of varying cell sizes. The lesson is very clearly organized with a useful student worksheet provided. They perform a lab experiment which is...

In this measuring chemicals worksheet, high schoolers investigate measurements of an aluminum slab including the length, width, height, mass, volume and density. They do the same for a piece of aluminum foil and they compare their...

In this density worksheet, learners measure the mass and volume of assigned objects and calculate the density. They then find the mass and volume of two objects given their densities and volume and mass respectively.

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...

High schoolers explore the formulas for volume of three-dimensional objects. They participate in various activities involving ice cream, ice cream cones, small candies, and gum balls, recording their calculations on a lab sheet.

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

All together now! Physical science pupils observe the effects of temperature and amount of substance on pressure and volume of a gas. The interactive resource guides learners through the Combined Gas Law, where they observe changing...

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

Adorn your classroom or science lab with posters about units of measurement. Each page has pictures and symbols to show even struggling learners how to define volume, weight, and capacity.
