Answer 3

Holding on.

Answer 4

These are the first 5, I have 10 I want you to check if you can right now. :)

1. A team of scientists is studying a volcanic hot spring.
Which task would the physical scientist most likely do?
A. Find out where the hot water is coming from.
B. Study the effects of the hot spring on humans. <---
C. Study the organisms that live in the hot spring.
D. Find out what elements are in the spring water.

2. Compounds consist of one or more atoms joining together to form a new substance.
From a scientific perspective, which makes the compound a system?
A. The compound contains both matter and energy.
B. The atoms in a compound interact with each other.
C. There are many different atoms that can make different compounds.<---
D. Compounds are made of materials that scientists want to study.

3. A museum is creating an exhibit about cells.
Which type of exhibit would best explain what cells are?
A. Use a life-size drawing of a cell.
B. Display a three-dimensional model of a cell.
C. Set up a microscope so that visitors can view cells. <---
D. Put a cell on a poster in the exhibit.

4. Models are used by scientists to analyze and understand a system.
How do models compare to what a scientist might be studying? <---
A. Most models simplify what the scientist is studying.
B. Most models are created as exact copies of what the scientist is studying.
C. Most models are larger than what the scientist may be studying.
D. Most models will be more complex than what the scientist is studying.

5. A cold dish of ice cream can be considered a closed system for a very short period of time. Which best explains this phenomenon?
A.The ice cream will eventually gain heat and melt. <---
B. The ice cream can be eaten.
C. The ice cream can be many different flavors.
D. The mass of the ice cream will change as it melts.

Answer 5

The answer to 1 is D. 2 is B. 3 could be B or C, but C is likely better as it conveys the size of cells. 4 is A. 5 is A.

Answer 6

KK! Thanks, Here's the next 5. :)

6. Which information about the earth would be represented when a globe is used as a model? Choose all answers that are correct.
A. the angle the sun hits the earth
B. the speed of rotation
C. the shape of the earth
D. the earth's tilt <---

7. Which information about the earth would not be represented when a globe is used as a model? Choose all answers that are correct.
A. the earth's magnetic field <---
B. the location of the earth's oceans
C. the location of the earth's continents
D. the earth's orbit around the sun <---

8. Why has the model of the atom changed over time?
A. All models of the atom created by scientists are too simple.
B. All atoms are unstable and are continuously changing.
C. The model of the atom changed as scientists made more accurate observations. <--
D. The model of the atom changed over time because the atoms changed composition.

Answer 7

Woops, I didn't post all of them :)

Answer 8

6 is C and D. 7 is A and D. 8 is C.

Answer 9

9. Why might the model of the atom change in the future?
A. The components of an atom differ from atom to atom and scientists have not discovered all the variations.
B. The components that make up an atom can change over time. <----
C. As new discoveries about the atom are made, scientists must update the atomic model.
D. Scientists are not able to see the atom, so all atomic models are a guess.
