4 ACTIVITY 1 Which Scientist Is Which? Match the scientist with what he/she studies. 1. paleontologist a. metals 2. entomologist b. human behavior 3. astronomer c. insects 4. metallurgist d. energy and force 5. agronomist e. water 6. hydrologist f. plants 7. archaeologist g. animals 8. psychologist h. prehistoric forms of life 9. chemist i. rocks 10. physicist j. structure and matter 11. botanist k. soil and crop raising 12. zoologist l. weather 13. geneticist m. stars and planets 14. geologist n. human DNA 15. meteorologist o. past cultures ACTIVITY 2 Branches of Science Write the branch of science each of the fields below would belong to: Physical Science, Earth and Space Science, Life Science, Mathematics, Social Science. 1. Zoology 11. Statistics 2. Astronomy 12. Biology 3. Physics 13. Geology 4. Anatomy 14. Psychology 5. Anthropology 15. Seismology 6. Geometry 16. Entomology 7. Botany 17. Archaeology 8. Mineralogy 18. Logic 9. Meteorology 19. Genetics 10. Chemistry 20. Ornithology 2

5 ACTIVITY 3 Write T for true or F for false for each statement. 1. A hypothesis is a statement that can be tested. 2. Theories attempt to explain why a particular thing happens. 3. Scientific laws explain why something happens. 4. An independent variable is the factor that is changed in an experiment. 5. A dependent variable is a factor that stays the same in an experiment. 6. A constant is the factor being measured in an experiment. 7. A control is a standard used to make comparisons. 8. An inference is a conclusion that is based on observations. ACTIVITY 4 SI Units The International System of Units (SI Units) was developed to provide a uniform standard for physical measurements that could be used worldwide. Next to each quantity, list the unit with which it is measured and its symbol. (The choices are in the box). K second cubic meter m meter kilogram s Kelvin kg m 3 Quantity Unit Symbol Mass Volume Time Temperature Length 3

6 /Physical Science ACTIVITY 5 Scientific Units of Measurement Use the words from the box to fill in the blanks and make the information correct. 1. The amount of matter in an object is called the of the object. 2. The mass of an object will be the on Earth or the moon. 3. A measurement of, on the other hand, depends on the force of on it. 4. is the measurement used to determine how hot or cold something is. Such measurements are made on the /Physical Science gravity boils weight absolute time mass temperature same Kelvin This scale starts at zero. At 373 K, water. scale. 5. An interval between two events is measured with the SI Unit of. ACTIVITY 6 Density The measurement of density refers to how the mass of an object (how many atoms are in it) compares to the amount of space that it occupies (the volume). Answer these questions about these squares of equal mass. 1. Which of the squares has the highest density? 2. Which of the squares has the lowest density? 3. How does the mass compare in all three squares? 4. How does the volume compare between the squares? 5. Which do you think has a higher density, a block of wood or a block of iron? 4
