Science Concept Check (next Tuesday)
This coming Tuesday, science students will be writing their Concept Check on the first part of the Pure Substance and Mixtures unit.
Here is a rundown of the test and the concepts (and associated textbook pages) that students should know before writing:
Part A (Knowledge and Understanding)
- Multiple Choice (12 questions)
- Matching (8 questions)
- Fill-in-the-Blank (5 questions)
Part B (Communication)
- Paragraph answers (3 questions)
1) Particle Theory
- Terminology: particle, theory
- Example Question: What are the five points in the Particle Theory?
- Example Question: What happens to the particles when a substance is heated?
- Textbook: 1.1 What is Matter
2) States of Matter
- Terminology: matter, state, solid, liquid, gas, definite/indefinite
- Example Question: How is the particle configuration different in solids, liquids, and gases?
- Example Question: What does it mean to say that liquids have a definite volume but indefinite shape?
- Textbook: 1.2 States of Matter
3) Classifying Matter
- Terminology: pure substance, mixture, solution, mechanical mixture, homogeneous, heterogeneous, alloy
- Example Question: Would tap water be classified as a pure substance, solution or mechanical mixture? Explain.
- Example Question: When baby oil is combined with water, does it form a solution or mechanical mixture? How do you know? Explain.
- Textbook: 1.4 Pure Substances and Mixtures
- Textbook: 1.6 Mechanical Mixtures and Solutions
