Praxis 5001 Science in Elementary Education 1 — Questions and Answers
Question 1: Which type of rock is formed when magma cools and solidifies?
- Sedimentary
- Metamorphic
- Igneous (Correct answer)
- Limestone
Correct answer: Igneous
Igneous rocks form when magma (underground) or lava (above ground) cools and solidifies; examples include granite and basalt.
Question 2: A student observes that plants placed near a window bend toward the light. This response is called:
- Geotropism
- Photosynthesis
- Phototropism (Correct answer)
- Hydrotropism
Correct answer: Phototropism
Phototropism is the directional growth of a plant in response to light, causing plants to bend toward the light source.
Question 3: The water cycle includes evaporation, condensation, and precipitation. What causes water to evaporate?
- Cold air temperatures
- Heat energy from the sun (Correct answer)
- Wind patterns only
- Gravity pulling water downward
Correct answer: Heat energy from the sun
Solar heat energy provides the energy for water molecules to escape from liquid water into water vapor through evaporation.
Question 4: Which of Newton's laws states that an object at rest stays at rest unless acted upon by an outside force?
- Newton's First Law (Inertia) (Correct answer)
- Newton's Second Law (F=ma)
- Newton's Third Law (Action-Reaction)
- Newton's Law of Gravity
Correct answer: Newton's First Law (Inertia)
Newton's First Law of Motion states that objects resist changes in their state of motion — a property called inertia.
Question 5: During a food web lesson, which organism is always a producer?
- Rabbit
- Hawk
- Oak tree (Correct answer)
- Mushroom
Correct answer: Oak tree
Producers are organisms that make their own food through photosynthesis; plants like oak trees convert sunlight into energy.
Question 6: A student mixes baking soda and vinegar and observes bubbling. This is an example of which type of change?
- Physical change
- Chemical change (Correct answer)
- State change
- Mechanical change
Correct answer: Chemical change
Bubbling gas produced by mixing baking soda and vinegar indicates a chemical reaction creating a new substance (carbon dioxide).
