In this learning activity you'll explore units of measurement.

Students identify the parts of a triple beam balance and practice measuring the mass of objects.

In this animated object, learners examine how to align a part on the 1808 CMM.

In this learning activity you'll test your knowledge of angular measurement in this 10-question quiz.

In this learning activity you'll review a visual overview of indirect measurement.

Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.

Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

In this learning activity you'll review a visual overview of inside measurement.

In this learning activity you'll review a visual overview of depth measurement using the depth micrometer.

In this learning activity you'll explore the difference between mass and weight.

Test your skills at reading a ruler.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

In this interaction the student is presented with 10 questions on indirect measuring devices and their uses.

In this animated activity, learners follow a step-by-step approach for connecting a digital multimeter to measure resistance. A brief quiz completes the activity.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

Learners read a step-by-step approach on how to connect an ohmmeter when making measurements in this interactive lesson.

As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.
