About This Chapter
Scientific Process & Inquiry - Chapter Summary
Polish your skills in conducting scientific research by working through this chapter. You will review measurement of mass, volume and temperature, the Standard International (SI) system of measurement, the procedures involved in the scientific method and how to work with equipment in the lab.
You'll reacquaint yourself with the glassware, instruments and other tools found in a chemistry lab, refresh your understanding of how living things are classified and named, and review how to calculate conversions between units of measurement. The lessons include the following material:
- Converting between units of volume and mass
- Using instruments to measure temperature
- Types and purposes of laboratory equipment and supplies
- Base and derived units of the SI
- Classification and taxonomy
- Scientific observation and questioning and the steps of the scientific method
Make the most of your study time by using this fully online and readily accessible study guide. These brief lessons are interesting and informative, and each is accompanied by a short quiz so that you can check your comprehension and retention of the material. The lessons never last longer than ten minutes, so your time is always used to your best advantage. Each video is accompanied by a transcript if you prefer reading to viewing, and our text lessons, like the videos, are well-written, well researched and skillfully presented.
1. Mass and Volume: Formulas, Unit Conversion & Practice Problems
Learn about how mass and volume are connected by a special formula, how to calculate volumes of common 3D shapes, and how to convert between different units of mass and volume. Complete some practice problems and perfect your skills.
2. Measuring Temperature in the Lab: Instruments & Process
In this lesson, discover what temperature is a measurement of while learning how to properly measure temperature in a lab. Learn about the important instruments needed for this essential lab skill.
3. Common Laboratory Equipment: Types & Uses
Biologists use all kinds of equipment in their labs to run their experiments. In this lesson, you'll identify some of the most common pieces of equipment as well as when you should or shouldn't use them.
4. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
5. Elements of the SI: Base & Derived Units
Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.
6. What is Classification in Science? - Definition & System
In order to understand things in science, we need organization. Because science is such a large umbrella term, we have to organize it into different topics. Learn more about classification in science, and take a quiz to test your knowledge.
7. Taxonomy: Classification and Naming of Living Things
The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.
8. How Scientific Observations Lead to Scientific Questioning
Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.
9. The Scientific Method: Steps, Terms & Examples
The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.
