1. LESSON PLAN BY KALINDI ZAVERI

2. TEMPERATURE Objectives: The pupil gains an understanding of melting point by experimentation The pupil develops scientific process skill of experimentation.

3. OTHER LEARNING OUTCOMES Science process skills developed Experimentation Observation Writing a lab report Research skill Representing and analyzing the data

4. SCIENTIFIC METHOD REVIEW WITH THE HELP OF QUESTIONS EXAMPLE:WHAT ARE THE STEPS OF SCIENTIFIC METHOD? WHAT IS A HYPOTHESIS? WHAT IS A VARIABLE?

5. LAB ON MELTING CHOCOLATE QUESTION: WHAT IS THE EFFECT OF TEMPERATURE OF CHOCOLATE HAVE ON ITS MELTING POINT? AIM/PURPOSE: RESEARCH QUE: What is the melting point ? HYPOTHESIS: MATERIALS REQD: PROCEDURE: OBSERVTION TABLE GRAPH REP CONCLUSION

6. NOTES Definitions of the following would be given INDEPENDENT VARIABLE: DEPENDENT VARIABLE: CONTROLLED VARIABLE:

7. PROCEDURE FOR THE LAB I CHOCOLATE BAR IS TAKEN. IT IS CUT INTO 6 PIECES EACH PIECE IS MEASURED FOR ITS LENGTH AND WIDTH 2 PIECES ARE THEN PLACED IN A REFRIGERATOR, 2 PIECES IN THE FREEZER AND OTHER 2 AT ROOM TEMPERATURE. AT THE TIME OF EXPERIMENTATION, EACH OF THE PIECES ARE PLACED IN A SEPARATE BEAKER WHICH IS LABELLED AS A, B & C AND THEN THE BEAKERS ARE HEATED ON HOT PLATES AND TIME FOR EACH PIECE TO MELT IS NOTED.

8. Rubric for lab Total points : 50 Question correctly written = 5 Purpose correctly written = 5 Research = 10 Hypothesis = 5 Procedure = 5 Observation table = 5 Graphical representation = 5 Conclusion = 5 Questions = 5

9. Web sites for Research: www.discovery.com www.brainpop.com

10. REMEDIATION THE PUPIL WOULD BE DOING THE EXPERIMENT HIMSELF, BUT WOULD BE ASSISTED AT EVERY STAGE. TEACHER WOULD SHOW THE ACTUAL MELTING OF ICE TO THE PUPIL AND TEACH HIM TO TAKE THE MELTING POINT. EXPLANATION WITH THE HELP OF POSTERS ON MELTING POINT.

11. CHALLENGING QUESTIONS WOULD THE RESULTS CHANGE IF YOU CHANGEDTHE BRAND OF THE CHOCOLATE? IF THE CHANGES OCCUR, WHAT CHANGES DO U EXPECT? ON WHAT FACTORS DOES THE MELTINGPOINT DEPEND?

12. Home work Design your own experimental design examples: temperature, time, boiling point, freezing point, effect of heat on …. Rubrics for the experimental design would be the same as the Chocolate lab.
