Think First Look around the room and describe things quantitatively and qualitatively. On a piece of paper make a T-chart. One side is titled “qualitative observations” and the other is “quantitative observations.” List as many as you can. Qualitative observationsQuantitative observations Please display your name cards.

Grading Policy

Grades will be based solely on the level of mastery for each area of content. Daily work and homework will not be used to determine level of mastery and thus, not factored in as part of the overall grade. Records will be kept of class work and homework completion, but these records will only be used to determine how much effort has been put forth and how well a student has prepared for an assessment. Some formative assessments will also be recorded as a means to show students how they are progressing, but they will not be factored in as part of the overall grade. Students may retake an exam or quiz if all of the homework is completed satisfactorily as well as an additional assignment to prepare for the retake. Retakes will be given on a designated day after school.

Materials you will need for this class TI-nspire handheld: issued by your math teacher. Bring to class every day. College or wide-ruled composition book. Please bring to class next class. Pen and pencil A section of a three-ring binder to keep written materials Lined notebook paper Graph paper We will use a classroom copy of the chemistry text. You will be able check out a text from the book room when needed to complete homework or study.

Observation and Math Skills Quantitative observations: measureable/objective Qualitative observations: not measureable/subjective Base units: kilogram (kg), meter (m) Derived units: density (kg/m3), volume (m3), mass flow rate (kg/s) Intrinsic properties: doesn’t change depending on quantity and composition (boiling point, density) Extrinsic properties: based on shape and quantity (m, v)

Candle observation mini-lab 1.Get into pairs Each group gets 1 candle. Make at least 10 observation (T-chart) about the unlit candle (quantitative and qualitative) When Mr. George has checked that you have decent observations, you can light your candle Make at least 10 more observations, obtaining quantitative data and creating data with derived units (at least 2). Use multiple trials. Create a graph of your data (multiple groups, rate, etc.) 2. When you are done clean your lab space and keep your observations in your notebook. You will turn it in at the end of the period. 3. Finish by__________ 4. If you finish early share your results with another group that is finished and be prepared to share your results with the class. Possible tools: Scales Your 5 senses A metric ruler Stopwatch/ Timer Something else you can think of (ask Mr. George if it is available)

Exit Ticket At the bottom of your candle mini-lab answer the following question on your own and turn this in before you leave Compare and contrast qualitative and quantitative observations.
