TIPS ON HOW TO PASS SCIENCE GED TEST

1. Comprehending scientific presentations that is understanding and interpreting scientific symbols, terms, phrases, and graphics, for example an hypothesis is an explanation that might be true and can be teste by additional observation and experimentation and a theory is a set of interrelated hypotheses that have been tested and confirmed many times by many different scientists.
2. Practice analyzing experimental and observational investigative designs that is understanding and using the scientific method (Independent and dependent variable, a control, a constant).
3. Independent variable is one which is manipulated while a dependent variable is the result of changes made to the independent variable and is what is being measured or observed, for example, the amount of time a plant is exposed to light is the independent variable while the resulting growth or death of the plant is the dependent variable, so growth or death of a plant is dependent on the amount of exposure to sunlight.
4. A control is a standard to which the resulting findings are compared. It’s a baseline measurement that allows scientists to determine if the results are positive or negative, for example the control can be a plant that receives no sunlight at all.
5. A constant in an experiment remains unchanged, for example all plants receiving sunlight should have the same amount of water, the same kind of soil, the same species of plant.
6. Practice using textual evidence and data to support a finding or conclusion.
7. Practice presenting scientific findings and theories in visual, numerical, and symbolic formats. For example, when applying a science formula, you can substitute quantities for the known variables and solve for the unknown variable. Also make sure to be familiar with some frequently used standard of measures like, the kilogram (kg) for mass, the meter(m) for length, the kelvin(K) for temperature, the ampere(A) for current, the mole(mol) for amount of substance etc., as you read a lot of science text you will come across some more.
8. Practice probability and statistics, that is describing data statistically, finding the mean, median, mode or range of a data set, and determining the probability of an event.
9. The skills mentioned above are used to answer questions from the different parts of the GED Science which includes Life Science (40% of the test), Physical Science (40% of the test) and Earth and Space Science (20% of the test).

11. Physical Science: Do make sure to read and understand texts on the following topics: –        Matter (Solid, liquid and gases), Balancing Chemical Equations, Temperature and heat (Exothermic and Endothermic reactions, Conduction, Convection and Radiation), Motion and forces (Newtons Law of Motion), Work and Power, Waves, Types of Energy
12. Earth and Space Science: Do make sure to read and understand texts on the following topics: Weather and Climate, Earth’s Structure, Earth’s Resources, Carbon Cycle and, Space and Solar System.
