Students will use standard safety practices for all classroom laboratory and field investigations. a. Follow correct procedures for use of scientific apparatus. b. Demonstrate appropriate techniques in all laboratory situations. c. Follow correct protocol for identifying and reporting safety problems and violations. S6CS4. Students will use tools and instruments for observing, measuring, and manipulating equipment and materials in scientific activities. a. Use appropriate technology to store and retrieve scientific information in topical, alphabetical, numerical, and keyword files, and create simple files. c. Read analog and digital meters on instruments used to make direct measurements of length, volume, weight, elapsed time, rates, and temperature, and choose appropriate units for reporting various quantities. S6CS6. Students will communicate scientific ideas and activities clearly. a. Write clear, step-by-step instructions for conducting scientific investigations, operating a piece of equipment, or following a procedure. b. Understand and describe how writing for scientific purposes is different than writing for literary purposes. c. Organize scientific information using appropriate tables, charts, and graphs, and identify relationships they reveal. S6CS7. Students will question scientific claims and arguments effectively. b. Recognize that there may be more than one way to interpret a given set of findings. S6CS9. Students will investigate the features of the process of scientific inquiry. Students will apply the following to inquiry learning practices: a. Scientific investigations are conducted for different reasons. They usually involve collecting evidence, reasoning, devising hypotheses, and formulating explanations. b. Scientists often collaborate to design research. To prevent bias, scientists conduct independent studies of the same questions. c. Accurate record keeping, data sharing, and replication of results are essential for maintaining an investigators credibility with other scientists and society. d. Scientists use technology and mathematics to enhance the process of scientific inquiry. Review Questions Know each of the major SI units of measure, what they measure, and how they are measured. Mass_________________/ _______________/ ___________________ Volume of a liquid - ________________/_____________/____________ Length - _______________/_______________/__________________ Temperature - _______________/________________/_______________ Volume of a solid - _______________/_______________/____________ In labs, what types of materials should be treated as potentially dangerous? ____ ____________________________________________________________________. List four tools scientists use in experiments._______________________, _____________________, _____________________, and __________________. When is playing around in a science lab authorized? ____________________. Identify each of the following items as either a model or not a model: car _________, toy car ____________, boat ____________, toy boat ____________, and map __________. How many meters are in each of the following metric units? Kilometer ______, decimeter _______, centimeter _________, and millimeter __________. Hot air __________ and cold air ______________. What part of a fire do you point the fire extinguisher? ______________________ Know the six steps in the scientific method. _____________________________, _____________________, ______________________, ____________________, __________________________, and ___________________________. Wearing goggles in a science lab is very important? List three potentially dangerous things that could hurt your eyes during a science experiment. _________________, ____________________, and _______________________. T F Models are possible substitutes if you need to conduct a scientific experiment. Although object X and object Y are the same size, object X is more dense than Y. If you place both of them in mud, which one will sink lower? ________. Why? ________________________________________________________________. T F It is better to conduct an experiment only once so you dont get confusing results. What is the first thing you do when there is an accident during a science lab? ________________________________________________________________. Why does hot air rise and cold air sink? ________________________________. If something gets hotter, the particles in it move (faster/slower), they get (more/less) dense, and they have (more/less) volume. T F A failed experiment is a waste of time. The person doing the experiment must have done something wrong and they must keep trying to do the experiment until they get it right. How many variables should you have in an experiment? ___________________. T F The best experiments have very detailed steps. What is the first thing you should you do if you find broken glass in a science lab? _________________________________________________________________. T F The best experiments are repeated many times. Why is an unsuccessful experiment good? _______________________________ _____________________________________________________________________ ____________________________________________________________________. What is density? ___________________________________________________. What is volume? __________________________________________________. T F Density and volume are the same thing. What is the meniscus? ______________________________________________. What are the four main sections of Earth Science? ________________________, ________________, _____________________, and __________________________. How does the water displacement method for determining liquid volume work? ____________________________________________________________________.
