Ch 1: Core Science Concepts: Help and Review

About This Chapter

The Core Science Concepts chapter of this High School Biology Help and Review course is the simplest way to master basic science. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of core science.

Who's it for?

Anyone who needs help learning or mastering high school biology material will benefit from taking this course. There is no faster or easier way to learn biology. Among those who would benefit are:

  • Students who have fallen behind in understanding the scientific method and core science concepts
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about core science concepts
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the core science chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the core science chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any core science question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a core science unit of a standard high school biology course. Topics covered include:

  • Scientific terms
  • Scientific methods and models
  • Experimental design
  • The metric system
  • Reading scientific charts and graphs

9 Lessons in Chapter 1: Core Science Concepts: Help and Review
Science Vocabulary & Concepts: Study Skills & Word Parts

1. Science Vocabulary & Concepts: Study Skills & Word Parts

Learning science presents a unique set of challenges for students. In this lesson, learn the tricks of the trade as we discuss scientific vocabulary and other science study skills.

The Scientific Method: Steps, Terms & Examples

2. 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.

Experimental Design in Science: Definition & Method

3. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

The Metric System: Units and Conversion

4. The Metric System: Units and Conversion

Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.

Unit Conversion and Dimensional Analysis

5. Unit Conversion and Dimensional Analysis

How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.

How to Read Scientific Graphs & Charts

6. How to Read Scientific Graphs & Charts

How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.

Characteristics of Living Things

7. Characteristics of Living Things

Have you ever wondered what makes something alive? Learn more about the characteristics that classify something as living. These shared traits can be observed in all living things in the world around us.

How Does a Hypothesis Become a Theory?

8. How Does a Hypothesis Become a Theory?

A scientist can collect and analyze data, and eventually publish a hypothesis about the data. In order for that hypothesis to become a theory, other scientists have to agree with it. In this lesson, we'll discuss how a hypothesis becomes a theory.

Operculum: Definition & Types

9. Operculum: Definition & Types

An operculum is a small covering, a lid, or a ~'trap door~' found on plants or animals. Read this lesson to learn where to find an operculum, as well as what it does!
