Taking the BIOLOGY SOL TEST TIPS and THINGS TO CONSIDER w/charts and graphs
Interpreting Charts and Images • You must look for patterns • Identify what is being asked for • Use prior knowledge of scientific research on subject matter. • In the example there are two parents that contribute but only one’s DNA fingerprint is present for analysis. • Choose the best answer • The closest choice is the obvious selection to make.
Interpreting Charts and Images • Comprehend the scientific key terms. • Herb is represnts of plant; vore is latin for eat. Apply common sense Meat eaters need many sharp teeth. Plant eaters don’t need that many sharp teeth to tear into it’s meal.
Interpreting Graphic Data • Y – axis is the measure of the variable tested • X – axis represents the variable being measured. • Look for peaks and declines represented by the lines or bars. • Look for key terms that indicate what the question implies such as maximize!
Interpreting Charts and Images • Identify terms • Best • Adapted • Picking up prey Beware of unnecessary information provided. Like measurements in the diagram provided. Size is not the issue accommodation is key here.
Interpreting Charts and Images • When analyzing images identify what you are looking for by reading the question thoroughly. • Scientific Method is applied here. • What is important for comparison when analyzing the effects of the IV on the DV. In the lab setup pictured above, a student is trying to determine the effect of pollutants on the growth of three groups of seeds. The results will not be valid because the experiment has no — A conclusion B hypothesis C control D variable
Interpreting Graphs • The Food Web is the required knowledge here. • If predator A decreases population B then population C in which B feed on will increase. This graph shows the sizes of lynx and hare populations between the years of 1845 and 1940. If a predator of the lynx enters the food chain, you might expect the number of — A lynx and hares to become equal B lynx to increase C hares to increase D hares and lynx to decrease
Charts • Understand the question then apply skills learned from genetics lessons. • Draw 3 Punnett Squares: They are necessary to simulate the chart data provided.
Images The implied knowledge here is cell types and parts and terminology for cellular life forms. • The one-celled eukaryotic organisms above are often found in freshwater ponds. What is one characteristic they all have in common? • A Cilia • B Nucleus • C Pseudopodia • D Flagellum
Charts • Look for the obvious data in conclusive data charts. • The question asks about production of leaves. • The increase in number of leaves based on the manipulated variable gives away the answer.
