ACT SCIENCE Study guides, Class notes & Summaries

experimental group - ANSWER the experimental part in which all conditions are kept the same except for the condition being tested explanation - ANSWER a statement that makes something clear extrapolation - ANSWER estimating a valu

Strategy for data representation and research summaries one thing - ANSWER Go straight to the question without reading the passage Strategy for data representation in research summaries questions that you can't answer with visuals - ANSWER Circle and come back later Data representation in research summaries after you answer all the questions you can do what with the visual questions - ANSWER Skim the passage for keywords and answer the remaining questions

apparatus - ANSWER To understand an experiment, you need to understand the apparatus. On the ACT Science Test, several questions ask about the apparatus and possible modifications. So part of your focus in reading and summarizing an experiment should be to take note of the apparatus. Dependent variables - ANSWER Dependent variables are those whose values are being measured-the results of the experiment. Experimental variables - ANSWER Experimental variables are the variables whose effects ...

Cell membrane - ANSWER An organelle found in all cells that acts as the passageway through which materials can pass in and out. This organelle is highly selectively permeable, only allowing materials to pass through that it "chooses" chemically. Cell wall - ANSWER An organelle found primarily in plant cells and fungi cells, and also some bacteria. The cell wall is a strong structure that provides protection, support, and allows materials to pass in and out without being selectively permea...

Ecliptic - ANSWER path of the sun and the planets Electric potential energy - ANSWER Energy a charge has due to its location in an electric field Electromagnetic Wave - ANSWER A form of energy that can move through the vacuum of space. Electrostatic force - ANSWER The force between electrically charged objects (like charges repel and opposite charges attract each other).

metamorphic rock - ANSWER A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions. mineral - ANSWER Elements found in food that are used by the body mitochondria - ANSWER An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur

cuticle - ANSWER A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants. cytoplasm - ANSWER A jellylike fluid inside the cell in which the organelles are suspended cytoskeleton - ANSWER A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement

Acceleration - ANSWER The rate that velocity changes per unit time and the direction it changes in. Computed from the change in velocity divided by the change in time. Common units are meters per second squared (m/s2 ). Acceleration due to gravity - ANSWER The acceleration of an object that is only acted on by the force of the Earth's gravity. This value is given the symbol g and near the surface of the Earth it has a value of approximately 9.8 m/s2. The direction of the acceleration due t...
