Parkside                                       CHICAGO IL 60651                                       (773) 534-6200Objective(s):The students (K-3) will be able to define what a thermometer is and observe changes in temperature using a thermometer. Materials Needed:Two thermometers, two empty pop cans labelled A and B, water, measuring cup, and a refrigerator with a working freezer, stop watch or clock with a second hand Strategy:Day 1Fill each can half full of waterPlace Can A in the refrigerator and Can B in the freezerMake a chart The chart should show the temperature of both thermometers before they are   inserted into the cans.  Times are charted at five minute intervals (5 minutes,   10 minutes, 15 minutes). Day 2Remove both cans from the refrigerator/freezer Leave both cans out for one hourBefore conducting the test get out your chartWrite on the chart the temperature of the thermometer before it is inserted into   the cans Place the thermometers in the holes at the top of the canRecord the temperatures on your chart after 5 minutes, 10 minutes and 15 minutes   on your chart Performance Assessment:Using the chart students should be able to fill in the appropriate numbers and symbols that represent temperature and orally explain their observations. Conclusions:Using the exam below (Note:This can be administered in written form or orally), students should be able to obtain 80% mastery.  1. How many cans were used? 2. How many thermometers were used? 3. How much water was put in each can? 4. Where was Can A placed? 5. Where was Can B placed? 6. On day 2, how long were the cans left out in the classroom? 7. How do you write 70 degrees? (Teacher directed) 8. Was there a difference in Can A and Can B after 5 minutes, 10 minutes and     15 minutes?  9. What were the differences? 10. Ask students what did they learn from this activity?   References:Fields Book of Science for Early Education Students '99.```
