  1. GRAPHS AND CHARTS • OBJECTIVE 1 • TEKS 2C

  2. Bar Graph A bar graph is used to show relationships between groups. The two items being compared do not need to affect each other. It's a fast way to show big differences. Notice how easy it is to see what was done in the experiment above with bean plant growth and different brands of fertilizer.

  3. Bar Graph Prediction Problem: Grade 11 April 2004 (1 of 5) 47 According to this information, what is the best prediction for the boiling point of the seven carbon alcohol? A 169°C B 178°C C 186°C D 192°C

  4. Analyze and Evaluate • The graph shows the amount of carbon-14 in tissue over time. According to the graph, if a bone contains 1/8 the amount of carbon-14 that it did originally, its approximate age is — • F 5,700 years • G 11,400 years • H 17,100 years • J 22,800 years

  5. Line Graph A line graph is used to show continuing data; how one thing is affected by another. It's clear to see how things are going by the rises and falls a line graph shows. This kind of graph is needed to show the effect of an independent variable on a dependent variable.

  6. Analyze: 4 According to the graph, what partial pressure of oxygen would saturate 67% of hemoglobin in the blood? A 2.8 kPa B 5.2 kPa C 8.7 kPa D 12.4 kPa 49 According to the graph, about how much hemoglobin would be saturated at an O2 pressure of 7.3 kPa? A 32% B 67% C 89% D 92%

  7. 39 The graph shows the distance traveled by a vehicle over a certain period of time. Which segment of the graph shows the vehicle moving with the greatest speed? A L B M C N D O

  8. 51 At which temperature do KBr and KNO3 have the same solubility? A 27°C C65°C B 48°C D80°C

  9. Circle (Pie) Graph A circle graph is used to show how a part of something relates to the whole. This kind of graph is needed to show percentages effectively.

  10. 47 Which graph best shows the comparison of the elements to the total composition of the copper ore?

  12. 4 Which statement is best supported by these data? A The solution’s freezing point remained constant with each increase in the amount of solute. B The freezing point of the solution decreased as the amount of dissolved solute increased. C The rate of freezing increased when more solute was dissolved in the solvent. D The solution remained a liquid because more solute was added to the solvent.

  13. 1 While studying the relationship between the pressure and the volume of a gas, members of a science class conducted an experiment in which they changed the pressure on a balloon and then measured the balloon’s volume. They collected the data on the table on the left. Which graph correctly represents these data?

  14. 52 The table shows the atomic radii of some elements in Periods 1 through 4 of the periodic table. Which inference can be made from this information? F Atomic radii decrease from left to right. G Atomic radii increase from bottom to top. H Atomic radii decrease from right to left. J Atomic radii double from top to bottom.

  15. Exercise #1 1.As the volume of a sample increases from 200 ml to 300 ml, what happens to the mass? Use the following graph of Volume vs. Mass to answer the next three questions. 2. According to this graph, what is the density of the substance being studied? 3. Based on the information provided in the chart below, what substance was represented by the data displayed on the graph?

  16. Exercise #2 • Create a lab report that replicates this experiment. Identify the materials, equipment and procedures.
