Part 4: Evidence Expert
A student adds 10 drops of vinegar to a piece of calcite mineral. They observe bubbles forming and a slight smell. The total mass decreases from 19.65g to 18.75g because some matter turned into a gas and escaped.

Read every scenario carefully—the answer is often in the details!
For "Claim-Evidence-Reasoning" questions, use at least TWO pieces of data.
Show your math for any Conservation of Mass problems.
Part A: Core Concepts
Section 1 of 3
1. A chef is making a salad dressing by mixing oil, vinegar, and herbs. Which statement best describes the salad dressing?
It is a pure substance because it is used for one thing.
It is a mixture because the different substances are not chemically bonded.
It is a gas because it can flow into a bottle.
It is not made of matter because it is a liquid.
2. A block of ice is heated on a stove until it turns into liquid water. Which of the following correctly describes what happens to the particles?
The particles lose thermal energy and stop moving entirely.
The particles gain thermal energy and begin sliding past each other.
The particles disappear as they are converted into heat.
The particles get bigger in size but move slower.
A student places a 50g beaker of water on a scale and adds 5g of salt. The salt dissolves and can no longer be seen.
3. What will be the final mass shown on the scale after the salt has dissolved?
50g, because the salt disappeared.
5g, because only the salt is left on the scale.
55g, because matter is conserved even when it dissolves.
45g, because some water evaporated during the mixing.
Part B: Spheres & Space
Section 2 of 3
4. Which of the following is an example of the atmosphere and the geosphere interacting?
A fish breathing oxygen in a lake.
Strong winds causing soil erosion on a mountain.
A plant growing in a garden.
Rain falling from a cloud into the ocean.
Sirius is a star that is much larger and hotter than the Sun, but the Sun appears much brighter and larger to us on Earth.
5. Why does the Sun appear brighter than Sirius?
The Sun is the largest star in the galaxy.
The Sun is much closer to Earth than Sirius.
The Sun is made of a special type of yellow fire.
Sirius only appears at night when it is darker.
A group of students wants to build a filter to clean pond water. They are told the filter must cost less than $10 and must be able to filter 1 liter of water in 5 minutes.

Grading Weight
Multiple Choice (Q1-6) 10 pts each
CER Response (Part C) 30 pts
Inquiry Variables 10 pts
Mastery Tip
"Focus students on the 'why'—especially for Conservation of Mass. If the mass stays the same, it's because matter can't disappear, even if it changes form or dissolves."
Part A & B: Multiple Choice
Q# Answer Expert Explanation 1 B Salad dressing is a mixture. The components (oil, vinegar) keep their properties and can be separated physically. 2 B Heating = adding thermal energy. Particles move faster and slide (liquid) rather than vibrating in place (solid). 3 C Law of Conservation of Mass. 50g (water) + 5g (salt) = 55g total. Dissolving doesn't destroy matter! 4 B Wind (Atmosphere) moving soil/rock (Geosphere) is a direct interaction that causes erosion. 5 B Proximity determines apparent brightness. The Sun is our closest star, making it appear much larger than distant, brighter stars like Sirius. 6 B A constraint is a limitation or rule. The budget limit ($10) is a constraint, while the goal (clean water) is a requirement/criteria.
Part C: Inquiry & Analysis
CER Rubric (The Chemical Mystery)
Claim (5 pts)
"Yes, a chemical change occurred."
Evidence (15 pts - 7.5 each)
Observation of color change (clear to blue).
Observation of gas production (fizzing/bubbles).
Observation of temperature change (feels hot).
Reasoning (10 pts)
"These observations are signs of a chemical reaction. A color change, the release of gas, and a change in thermal energy indicate that new substances were formed that were not there before."
Inquiry Variables (Lab Design)
Independent Variable
The shape of the boat
Reason: This is the one thing the scientist purposely changed.
Constant Factors
Type of plastic OR Amount of water
Reason: These must stay the same to make it a 'fair test'.
