  2. Science Curriculum

  3. Objective 1: Nature of ScienceVocabulary • Toxic • Corrosive • Dilute • Flammable • Waft • Biohazard • Temperature • Mass • Volume • Time • Distance • Accurate • Precise • Observation • Problem • Hypothesis • Independent variable • Dependent variable • Control group • Experimental group • Constant • Prediction • Inference • Trend • Pie (circle) graph • Line Graph • Bar Graph • Valid Conclusion • Claim • Critique • Theory • Law

  4. Lab Safety • Toxic: • Corrosive: • Dilute: • Flammable: • Waft: • Biohazard: Poisonous, harmful Acid, burns the skin lower the concentration, (acidwater) catches on fire easily safely smell, protect your respiratory system caution bodily fluids (blood, urine, bacteria, fungi)

  5. LAB EQUIPMENT

  6. Measurements • Temperature: • Mass: • Volume: • Time: • Distance: • Accurate: • Precise: thermometer(*C, *F, Kelvin) triple beam balance, scale, (kilograms or grams) Graduated Cylinder, buret, pipet (milliliters) stopwatch (hours, minutes , seconds) Meter stick ( kilometers, meters, centimeters) Exact true value (accuRIGHT) consistent, close together, nearest decimal (pREPEATABLE)

  7. Never to measure, only to hold and heat liquids Used to swirl and slows evaporation rate Used to observe chemicals Used to measure volume in mL (precise) Used to measure volume in mL (more precise) Used to measure small amounts of volume in mL (most precise) Used to hold HOT beakers Used when working with toxic gases or noxious fumes Used to measure time in hours, minutes, seconds Used to measure mass in kilograms, grams, and milligrams Used to measure temperature in *C, *F, and Kelvin Used to measure distance in kilometers, meters and centimeters

  8. Scientific Method question you want to solve • Problem: • Observation : • Inference: • Hypothesis: • Independent variable • Dependent variable: • Control group: • Experimental group: • Constant: see, smell, taste, hear, feel gathered from clues try to answer or solve the question (If _______, then ________) : added, tested or changed in an experiment (x-axis) what happened from the change, has to measurable, (y-axis) group or set up that was left alone groups tested (with independent variable) what was the same in all groups

  9. TIM & MOBY’s “Scientific Method” • Problem: Why is Moby’s plant dying even though it is being watered every day? • Observations:The leaves are brown and falling off, and the soil is wet and squishy • Inference: Maybe Moby is watering his plant too much. • Hypothesis: Fig trees grow best when watered only once a week. • Independent variable:Amount of water • Dependent variable: The plants growth • Control group: A • Experimental groups: B,C,D • Constants: same kind of plant, same pot, same soil, and same amount of sunlight • Conclusion: Fig trees grow best when watered only once a week

  10. Interpreting Charts and Graphs what you think is going to happen • Prediction: • Inference: • Trend: • Pie (circle) graph: • Line Graph: • Bar Graph: • Valid Conclusion: gathered from clues pattern shows % or parts of a whole shows relation between independent and dependent variables used to compare groups or categories restate results with data or evidence to support it
