Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Your young forensic scientists add to and strengthen their measurement and conversion skills with these seven well-scaffold worksheets. Metric conversions, measuring length, area, and volume, reading thermometers, graduated cylinders,...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

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...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Elementary schoolers learn about metric units and how they are used by engineers. They learn how engineers use the units to measure mass, distance, and volume. Then, they estimate measurements of units, and compare them to actual...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

We all have standards and scientists are no exception. Presentation covers standard temperature, standard pressure, temperature conversions, and absolute zero. It explains pressure using pascals, mm of mercury, atmosphere, and torr, then...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Students calculate the SA/V ratio and volume of phenophthalien agar that are cut into different shapes. They then let ammonia diffuse into the various pieces of agar and determine the effect that SA/V had on the rate of diffusion.

High schoolers 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...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Pupils study how to measure and calculate the volume of water flowing down a stream or canal and use simple tools to make measurements. Next, students determine how many people cold live off the volume of water measured. Finally, they...

High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

Learners work with measurements of length, area, and volume capacity of a liquid. They watch a teacher demonstration of both English and metric units before they estimate and take actual measurements of assigned items a three different...

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.

For this measurement worksheet, students fill in a chart with the proper SI units, measurements and symbols. They also practice converting from one metric unit to another. They express numbers in scientific notation.

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Students set up composting sites that allow food scraps and paper to be recycled by nature. They are introduced to one aspect of recycling; composting. Students see how God recycles as the worms change garbage into something that brings...

Enjoy a hands-on lesson that will certainly hold water with your classes. Young scientists design an experiment to determine the materials that absorb water the best. They test both man-made and nature-made materials and conduct...

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.
