Sections covered on the exam: Nature of Science, Life Science, Earth and Space Science, Physical Science.
Question 1 · Nature of Science
A student wants to test how fertilizer affects plant growth. She plants identical seeds in two pots. One pot receives fertilizer and the other does not.
Answer: C. Amount of fertilizer
Explanation The independent variable is the factor that the scientist changes in an experiment. Fertilizer is intentionally changed. Plant height is measured as the result. Therefore, fertilizer is the independent variable.
Question 2 · Nature of Science
Answer: D. Developing solar panels from energy research
Explanation Scientific knowledge about energy conversion led to technologies such as solar panels, which convert sunlight into electricity.
Question 3 · Earth and Space Science
| Original Rock | Metamorphic Rock |
|---|---|
| Limestone | Marble |
| Shale | Slate |
Answer: D. Troposphere
Explanation The troposphere is the lowest atmospheric layer. Important facts: Weather occurs here Contains most atmospheric gases Height about 8–15 km.
Question 4 · Physical Science
Answer: B. Do work
Explanation Energy allows objects or systems to perform work or cause change. Examples include moving objects, producing heat, and generating light.
Question 5 · Life Science
Answer: A. Chromosomes
Explanation Genes are segments of DNA found on chromosomes inside the nucleus. They carry instructions for inherited traits.
Question 6 · Nature of Science
A student investigates how temperature affects the rate at which sugar dissolves in water. The student uses the same amount of sugar and water in each trial but changes the water temperature.
Answer: C. Time required for sugar to dissolve
Explanation The dependent variable is the factor that is measured during an experiment. In this investigation: Independent variable: water temperature Dependent variable: time required for sugar to dissolve.
Question 7 · Nature of Science
Answer: B. Developing vaccines using biological research
Explanation Scientific research in biology led to medical technologies such as vaccines.
Question 8 · Earth and Space Science
Answer: B. Stratosphere
Explanation The ozone layer is located in the stratosphere and protects living organisms from UV radiation.
Question 9 · Physical Science
Answer: B. Kinetic energy
Explanation Kinetic energy is the energy of motion. Moving objects such as cars or flowing water possess kinetic energy.
Question 10 · Life Science
Answer: A. Chromosomes
Explanation Chromosomes are structures made of DNA that contain genes responsible for inherited traits.
