Measurements & Uncertainty in Science

1. Measurements & Uncertainty in Science

To be valid and reliable, scientific experiments must be based on data that is precise and accurate. Explore techniques for making measurements, review example measurements, and understand how to make calculations with measurements.

Elements of the SI: Base & Derived Units

2. Elements of the SI: Base & Derived Units

The International System of Units (SI) is an addition to the original metric system that can be updated as technology allows for increased precision in measurements. Learn about the concept of base units, such as meters, kilograms, and seconds, and understand how derived units are found by calculating them.

The Metric System: Units and Conversion

3. The Metric System: Units and Conversion

Scientists all over the world need to use a common language when reporting the measurements they make, which they do by using the metric system. Explore the metric units for length, mass, volume, density, and temperature, and discover how to make different conversions.

Unit Conversion and Dimensional Analysis

4. Unit Conversion and Dimensional Analysis

Dimensional analysis is used in converting different units of measure through the multiplication of a given proportion or conversion factor. Learn how to solve single-step and multi-step problems using dimensional analysis and understand the cancellation of units in a numerator and denominator.

Significant Figures and Scientific Notation

5. Significant Figures and Scientific Notation

A significant figure is a number that is necessary to express precise measurements. All non-zero numbers, zeros located between two non-zero numbers, and trailing zeros in numbers with a decimal point are significant figures. Learn about significant figures and how to express calculations in scientific notation.

Factor-Label Method in Chemistry: Definition, Examples & Practice Problems

6. Factor-Label Method in Chemistry: Definition, Examples & Practice Problems

The factor-label method in chemistry is a method for converting units of measure from one kind into another using factors made from the equalities between the units. Learn more about the definition of the factor-label method, including simple and derived unit conversions, study examples of the method in chemistry, and complete practice problems.

Thermometer: Definition, Types & Examples

7. Thermometer: Definition, Types & Examples

A thermometer is a device used to measure temperature. Learn about the definition and types of thermometers, explore examples of thermometers that are using solid, liquid, and gas, and discover how they are used.

Measuring Temperature in the Lab: Instruments & Process

8. Measuring Temperature in the Lab: Instruments & Process

In a lab, scientists measure temperature either in Fahrenheit, Celsius, or Kelvins. This lesson explores the process and instruments a scientist would use to work with the different temperatures.

Bradford Protein Assay: Advantages & Disadvantages

9. Bradford Protein Assay: Advantages & Disadvantages

In chemistry, the Bradford protein assay is a method for measuring proteins using blue dye. Gain a better understanding of the process as well as its advantages and disadvantages.

Bradford Protein Assay: Principle, Protocol & Calculations

10. Bradford Protein Assay: Principle, Protocol & Calculations

Explore the Bradford Protein Assay for measuring the protein concentration in a sample. Examine the Bradford Protein Assay Principle, discover the standards and steps for calculation, and view sample calculations.

Biuret Test: Definition, Procedure & Reagent

11. Biuret Test: Definition, Procedure & Reagent

A biuret test is used to detect the presence of peptide bonds, or proteins, in a substance. Learn more about the definition, procedure, and copper sulfate reagent used in a biuret test.

Lowry Protein Assay: Principle, Protocol & Mechanism

12. Lowry Protein Assay: Principle, Protocol & Mechanism

The Lowry protein assay is a method for determining protein concentrations. Learn more by exploring the principles, protocols, mechanisms, and steps in the reaction of the Lowry protein assay.

How to Take Measurements with Scales, Meters & Gauges

13. How to Take Measurements with Scales, Meters & Gauges

Learning different styles of measurements can help to calculate and plan logistically and architecturally. Explore the necessity of taking measurements and learn how to measure weight, speed, and time using scales, meters, and gauges.

How to Read and Interpret Scale Drawings
