MTEL Middle School Mathematics and Science Test Answer Key

1. A: One of the functions of leaning math is improving reasoning ability and honing critical thinking skills and discovering these talents are applicable in all academic disciplines as well as issues in the real world. Students discover patterns and relationships and the activity becomes a meaningful learning experience rather than a rote exercise in memorization.

2. C: The steps described are not necessarily used in exactly the same way in all sciences. Sometimes they happen at the same time or in a different order and may be repeated during the course of the study. The steps are: pose a question, research the issue, form a hypothesis, design and conduct an experiment, and analyze the results.

3. B: The cell is the basic building block of all living things; it is the smallest unit of life able to function on its own. There are two kinds of cells: prokaryotic which are present only in bacteria and eukaryotic found in all other life forms. New cells form by dividing from existing cells.

4. C: Energy is the capacity to do work or cause change. It is always associated with movement. Its companion is entropy, which is the measurement of energy unable to do work. Energy can change forms but it cannot be created or destroyed. There are two types of energy: potential which is energy that is stored and waiting to be used and kinetic which is energy that is currently being used.

5. D: A chemical reaction is a process that changes one substance into another substance (the product) with an altogether different structure and composition. There is a rearrangement of the bonds (strong electrical force) that hold the atoms together; however, the total mass and number of atoms equals the sum of all the reactants (the original materials). Energy is always either consumed or liberated.
