TEST REVIEW

1. Vocab Section: Go through the vocab words for this unit. Decide how you will review them. Options:

- Create flash cards

- Create Frayer models

- Write down any you are not sure about with definitions

Be ready to answer multiple choice questions about these words, and answer short answer questions that compare or define these words

2. Concept Section: Get ready to answer multiple choice and short answer questions about science concepts from Unit 1. These include:

- Structure and properties of matter (what each of these mean and how they are related)

Structure of Matter

YouTube Playlist: Structure and Properties of Matter

- Chemical changes vs Physical changes (what are the signs of a chemical reaction?)

Signs that a chemical change has taken place

Physical and Chemical Changes Video

- Atoms vs Molecules

- Conservation of Mass: what is it? How does it apply to chemical reactions?

- Polymers - what is unique about their atomic structure?

3. Written Section: be ready to use vocab and concepts to answer questions. Also consider:

- What is the format for a hypothesis?

A testable, declarative statement that states the relationship you think you will see between the independent and dependent variables. It is NOT an if/then statement, and it does NOT start with "I think" or "I predict." Examples:

• Plants that receive fertilizer will grow more than plants that do not.
• Students who sleep more will earn better grades on the next exam than students who sleep less.
• Increasing the amount of sodium borate in a polymer will increase the bounciness of the polymer.

- In an experiment, how do you find the IV, DV, and constants?

Independent and Dependent Variables

- What is the format for a conclusion? What parts need to be there?

1. Restate hypothesis
2. Make a claim ("The hypothesis was true," "The hypothesis was proven to be false," or "The results were inconclusive.")
3. Use data to support your claim (this should be actual NUMBERS from your data that support your claim).
4. Conclusion (In conclusion, we learned that ... ")

- When is says "use evidence to support your answer," what does that mean in the context of an experiment?

Two people will start out as "it." They are monomers. As they tag people, they become part of their polymer chain (link arms and stay together). People that are part of the chain may only WALK. Everyone must stay inside the tables.
