My Summer – Truth? Lie?

• We added 5 pets to our family.• I moved this summer.

• On your entry task paper, write your truth and lie under TUESDAY. Don’t tell yet!

• Share and see who gets the right answer!• Most outrageous truths• Most convincing lies

4 Corners

• Corner A, B, C, D• Walk to show your answer• Before we start, silently pick someone you

think you have little in common with. You may be surprised

• Sit back down and discuss.

9/5/12 Wednesday

• Entry Task:

• Write down one thing you’re looking forward to about this school year.

• Per 1 and 2 room tour• Per 2 and 3 – tour for building expectations• Finish FISH!• Per 5 – Handbook review

9/6/12 Thursday

• Entry Task: • What do you think is the most important

behavior of successful students?

• Per 2 and 3 Syllabus and MI survey

Introduction to Class

• MI Survey – graph as homework! Due Friday• Cards

– FIRST and LAST NAME– Your strongest intelligence– Your goal for a grade– Hopes for the class– Concerns for the class

• What is Chemistry? P. 41• Syllabus – units we will cover, grading, materials• PARENT CONTACT AND SIGNATURE DUE MONDAY! • Your learning goals – choose a topic from syllabus to write

on leaf…

Learning Commitments – help shape them…

• GOAL: create a list of commitments to be successful learners.

• Each team will brainstorm THREE successful student behaviors we can commit to. Try to keep them short and sweet, yet cover all the key points.

• Share and find common themes.• Each class will have a poster of their learner

commitments.

9/7/12

• Entry Task:

• SAY SOMETHING NICE! – watch video, write our own, share

• Table leaders – gather papers, paper clip and turn in

• Reminder – syllabi due MONDAY• MI Survey due TODAY

Week of 9/10-9/149/10/12 Monday

• Entry Task:

• What do you recall to be the most important aspects of lab safety?

• How will you demonstrate safety in the lab?

• PLEASE TURN IN YOUR SYLLABUS!!!!!• Find old or nametag new bins…

SAFETY

• Complete chemistry safety assignment and quiz – turn in.

• Has everyone turned in a safety contract? • Cut them, hand me bottom portion. • Glue top portion to page 1 of notebooks.• Glue “Designing an Investigation” to pages 2

and 3.• This document will guide your experimental

design.

9/11/12 Tuesday

• Entry Task

• Listen to a “story” about Calcium. • Write down 2 interesting things you heard.

• Glue lab sheet to page 4. • Tomorrow we will consider the rubric…this will be

attached to your team poster…

Begin thinking experimentally…

• GOAL: conduct a lab and make a poster of your investigative QUESTION, HYPOTHESIS, DATA and CONCLUSION.

• To start: Get in teams of 3-4.• Read through lab paper and rubric.• Follow the steps listed on the bottom. • ROUGH DRAFT – begin your poster in pencil…

complete in color.

Continue…

• Working on your posters. • Remember to consult your scientific method

guide when necessary:• Step 1 – Question (includes variables)• Step 2 – Hypothesis• Step 4 – Materials and Procedure – given to you!• Step 5 – Data Table – design one and collect

the data.• Step 6 - Conclusion

your scientific method guide on page 2 or your notebook.

• ROUGH DRAFT – begin your poster in pencil…complete in color.

9/12/12 Wednesday

• Entry Task

• Listen to a “story” about Chlorine. • Write down 2 interesting things you heard.

• But remember, when calcium and chlorine form a COMPOUND their characteristics can be totally different: CaCl2

SAFETY in the lab• Put all papers and books under table EXCEPT your

poster – you’ll need to record data!• Goggles at all times. • ONE STUDENT per group should wear gloves and do

the measuring and stirring of CaCl2.• You may TARE and measure the CaCl2 into the paper

cups.• CAREFUL with glass thermometers!• The lab will take approximately 20-35 minutes.

PLEASE STAY ON TASK!!!• I will call for CLEAN UP at 5 minutes to the bell. You

must return all materials exactly as you found them.

Chemical Reactions

• All chemical reactions release or absorb energy. Chemical reactions that release energy in the form of heat are called exothermic reactions. Some chemical reactions absorb energy and are called endothermic reactions.

• CaCl2 (s) Ca2+ (aq) + 2 Cl-(aq)• Reactants:calcium chloride + water • Products: ions of calcium and chlorine

(charged particles)

water

9/13/12 Thursday

• Entry task

• What makes a good poster?• Choose a poster in the room. Make a list of what

makes it a good poster.

• Clear desks. Retrieve posters from back table. • REMINDER: only ONE student from each team to

wear gloves. GLOVES ARE TO BE REUSED until lab is complete. Store in science bin.

Writing Conclusions…

• Consider the data table…discuss HIGHS and LOWS.

• What can you conclude?• Was your hypothesis supported with data?• Write your conclusion using RADDS• R is for restating the investigative question. • A is for answering the question.• D1 is about the HIGH data point. D2 is about the

LOW data point. • S can be your scientific explanation.

Endothermic or Exothermic

• All chemical reactions release or absorb energy. Chemical reactions that release energy in the form of heat are called exothermic reactions. Some chemical reactions absorb energy and are called endothermic reactions.

• CaCl2 (s) Ca2+ (aq) + 2 Cl-(aq)• Reactants:calcium chloride + water • Products: ions of calcium and chlorine (charged

particles)• Please also research the energy changes of

dissolution of salts in water
