When we measure matter, we are usually measuring physical properties. But sometimes, we are looking more about how to investigate what we know about the matter we see every day. In this lesson, you will learn more about the differences between facts, theories, variables, and hypotheses. These are all key ingredients to measure the world around us!

As you prepare for the module exam, make sure you're using the study tools right on our class resource page! Start by reviewing your guided notes (available in each lesson on the first and last pages or in the "Notes" tab at the top of the lesson window). A great trick is to cover up the main terms or answers and see if you can explain the concepts out loud in your own words.

Next, take the sample quizzes for each lesson without looking at your notes. When you finish, check your answers to see what you've already mastered and exactly which topics need a quick second review before you take your test!

In Module 1, we discussed the different measurements of matter. In this lesson, you'll learn more about how the states of matter and energy are connected.

When we talk about things like molecules and compounds, it's usually impossible to see these things directly. Instead, we rely on models, which are representations of the real world but in a way we can understand. You are very familiar with models already: a weather map, a planetary model, or even a diagram of the brain. In this lesson, you'll make a model of your own.

What do we know about atoms, except that they are very, very small? There have been lots of theories about atoms in the past, and in this lesson, we will explore some of the things we know - and don't know yet - about atoms. In this lesson, you'll learn about the Atomic Theory and how scientists formed it and changed it over thousands of years.

When something is sour, it's usually because it's acidic, while slick compounds are often basic. These two properties, acidic and basic, are measured in a special scale called pH. In this lesson, you'll learn about the pH scale, and common items that are either acidic or basic.

For this module exam, you will need to answer around 40 questions that include the topics in Module 1, 2, and 3. Some of your questions are multiple choice and some are matching and other types of questions.

Hot tip: Read each question carefully! Many students answer questions incorrectly because they don't read the full question. When writing an answer, make sure to use your best grammar and clearly explain your reasoning.

PREPARING FOR THE SEMESTER EXAM:

Remember:

1. There are two parts of the final exam. They are averaged together for your final grade.

2. Use your guided notes from each section to identify the topics that you know and where you still need to study. See the tip below

3. Did you use the videos in each section above to prepare for the exam.

Great Study Tip: At LSS, we STRONGLY suggest that you use the guided notes to help you prepare for the exam. Here's how: 

• In any lesson, click on the "Notes" link on the menu at the top of the page:

• Open the guided notes and print out a fresh copy of each as a study guide. Without using your notes, try to fill out the guided notes. You'll very quickly identify where you need to study more.

Like photosynthesis, cellular respiration is all about energy. In cellular respiration, however, energy that was stored from photosynthesis is converted into things that all living things can use to grow, move, and reproduce. In this lesson, you'll learn about this process, and the paired formula that is the opposite (sort of!) of photosynthesis.
