The Science assessment, offered as part of the Georgia Assessments for the Certification of Educators, is divided into two tests.
The first test consists of 80 selected-response questions. The content areas covered by the first test are scientific inquiry, processes, technology, and society; and physical science. The scientific inquiry, processes, technology, and society subarea covers the nature of scientific inquiry and processes, including the collection and analysis of data. It also includes questions about the relationship of science and technology to society and the environment. The physical science section covers the organization of matter; the atomic model; relationships involving energy and matter; chemistry, including periodic table, compounds, formulas, bonding, reactions, and solutions; and physics, including mechanics, electricity and magnetism, and wave properties.
The second test consists of 80 selected-response questions. The content areas covered by the second test are life science and Earth and space science. The life science subarea covers the structure of cells and basic cellular processes, including genetics; and mechanisms of evolution, characteristics of organisms, and principles of ecology. The Earth and space science section covers geology, including Earth’s structure, rocks, minerals, plate tectonics, and historical geology; the hydrosphere and atmosphere, including the water cycle, bodies of water, weather, and climate; and astronomy, including solar system, stars, and other features of the universe.
The examination must be completed within four hours. Test-takers will receive performance indices indicating their success in each subarea of the examination. Scores will be available approximately a month after the date of the examination; unofficial results are posted on the internet, and an official score report is mailed to the test-taker, the Professional Standards Commission, and the institution specified by the test-taker during registration.
GACE Science Practice Questions
1. Why are plant proteins called “incomplete proteins”?
A: they supply less energy than animal proteins
B: they contain cholesterol
C: they contain no amino acids
D: they lack some of the essential amino acids
2. Which of the following is an example of a third-class lever?
B: bottle opener
C: baseball bat
3. Which problem occurs when the human eyeball is too long?
4. A heavy stone wheel is resting on the ground. A student attempts to roll it forward, but finds it impossible. Which form of friction is acting against the student?
A: sliding friction
B: fluid friction
C: rolling friction
D: static friction
5. A plastic bottle is filled with water and sealed. If the bottle is squeezed at its base, where will the increase in water pressure be the greatest?
A: the increase in pressure will be the same throughout the water
B: near the top of the bottle
C: near the bottom of the bottle
D: in the center of the bottle’s gravity
1. D. Animal proteins contain the full battery of amino acids.
2. C. A third-class lever has an input force in the same direction as the output force, with both forces positioned on the same side of the fulcrum.
3. B. When the eyeball is too long, it is impossible for distant objects to become accurately focused on the retina.
4. D. Static friction is the force that makes it more difficult to set a stationary object in motion than to keep it in motion.
5. A. The fact that force applied to a confined fluid results in a uniform increase in pressure is known as Pascal’s principle.
