  1. Safety

  2. Bellchallenge: Equipment Scavenger Hunt • Match the equipment given to you at the door to the correct name located on the desks • Once you have found the correct name, have a seat • With your partner sitting next to you, place the steps of the scientific method in the correct order • When you finish both of the above, sit and wait quietly for the rest of the class

  3. Scientific Method • Problem • Research • Hypothesis • Materials • Procedure • Data • Conclusion

  4. Equipment Scavenger Hunt Presentation(scientific method focus: materials) State each of the following: • Your name • Name of equipment • What do you believe it is used for?

  5. Bellchallenge: Come in quietly & place your belongings on the wall that says bags. Read the 4 different group roles and their responsibilities. Decide which one you qualify for. Write your name in under that role. If all the spots have been taken, choose another role. Stand next to the poster you chose.

  6. Team Building • Class will discuss each role • Team leaders will chose their teams • Material’s manager will choose one of the tables (this will be your group’s name) • Scribe will write down group’s name and names of members • Engineer will turn in the sheet and get a piece of syllabus from teacher

  7. IAN Setup • The Interactive Notebook is: • Classwork, homework, notes, quizzes, etc will all be attached inside notebook. • Notebook checks every other week

  8. IAN Setup • Inside cover-attach Table of Contents • First inside page-Cover page • Include in cover page-name, period, subject & 2 biology visuals

  9. Syllabus Activity In your groups, • Create a visual of your designated part of the syllabus • Present your section and visual to the class

  10. Bellchallenge: In complete sentences, list at least 4 things you observe in the classroom below.

  11. Lab safety guidelines • Inform teacher immediately of any mishap-fire, injury, breakage, spills, etc • Follow teachers instructions & school’s procedures dealing with emergencies • Do NOT wear loose clothing & avoid sandals or open-toed shoes. • Wear safety gloves, goggles, and aprons as instructed • Tie back long hair & loose clothing to keep away from flame & equipment • NEVER eat or drink in the lab • Do NOT inhale vapors or taste, touch, or smell any chemical or substance unless instructed to do so • Do NOT point heated containers-test tubes, flask-at yourself or anyone else

  12. Safety Wheel • Activity Biohazard Hazard: organism/ biological materials may be harmful to humans Toxic Hazard: poison may if touched, inhaled or swallowed Corrosive Hazard: chemicals may irritate or eat away at the skin Electrical Hazard: possible danger from electrical shock SAFETY Radioactive Hazard: materials may be radioactive Flammable Hazard: chemicals may catch afire 1. Attach the correct safety symbol to each hazard. 2. Give an example scenario of each

  13. Safety Symbols

  14. Bellchallenge Safety Equipment LocationFind the location of each of the following in the room

  15. Bellchallenge: Briefly describe what you see in the graph below. (at least 3 complete sentences) • Every graph should contain: • Title • Labeled axes • Units on axes (if quantitative) • Proper increments • Best fit line (if line graph) This is a graph of temperature versus time. The time is the independent variable, while the temperature is the dependent variable. There appears to be a trend. As the heating time increases, the temperature increases.

  16. Identify the Independent & Dependent Variables Independent variable: Dependent variable: Independent variable: Dependent variable: Different months Types of pies Rainfall levels (in inches) % of people who prefer that pie

  17. What’s wrong with the graph? Title Student names?

  18. Measurement Activity In groups, • Answer the questions in the measurement section • Collect the date required data in the data collection section • Record your group’s data for heartbeats/minute on the board (& record theirs) • Create a graph of everyone’s recorded data

  19. I. Measuring • Units • Fill in the following units and symbols missing in the table. • Why is it important to use units when collecting data? _________________________________________________

  20. Data Collection

  21. Identify the value being measured, units used & equipment Graduated cylinder Mass= 352g (grams) volumei= 35L (liters) volumef= 52L (liters) What’s the volume of the rock in the graduated cylinder? • Volume= Vf-Vi= 52L- 35L= 17L

  22. Density Density is the amount of mass within a given volume (or D=m/V) What would the density of the rock be if: mass= 352g and volume= 17L D=m V =352g 17L =20.71g/L

  23. Bellchallenge: Briefly describe what is happening in the animation below. (at least 3 complete sentences) Toxic chemicals can be fatal if inhaled. These chemicals have to be handled in well ventilated areas (fume hood). The fume hood traps most of the vapors and send them out of the lab through a chute at the top.

  24. Scientific Method Cards • Problem • Research • Hypothesis • Procedure/Experiment • Data • Conclusion
