STAAR Test Questions about the Boiling and Freezing Points of Water are shown on this page.
Please contribute teaching ideas for TEKS 5.5B , which is for students to know the boiling and freezing point of water in Celsius degrees.
1. Start using Celsius degrees to record the daily temperature.
2. Point out that the daily temperature describes the weather.
3. Students need to know what ambient temperature is (the temperature around them). Room temperature is the ambient temperature of the room.
Activity: Assign students to be responsible for measuring the ambient room temperature for a period of time.
Ask students to record the measured room temperature in their science notebook. Binders allow students to add materials. You might have them to have a divider for weather. Using at least 5 days, ask the class to calculate the average ambient temperature of the classroom.
Students should be prepared to read the temperature from a diagram of a Celsius Thermometer.
Since the STAAR tests are to encourage critical thinking, I discussed the inaccuracy of question #2 on the 2011 STAAR test with a TEA representative.The response was that it doesn’t make any difference where water samples are taken, the boiling point of the water would be 100 C or close to it.
Parents and Teachers,
Know that you cannot trust the STAAR tests to be correct nor to represent the correct science process skills. TEA does not respond with a positive attitude to questions about errors on the STAAR tests. This is because admitting an error has been made means student grades have to be changed. Thus, not to spend money to change student grades, TEA just stops responding to inquiries about incorrect questions. This results in students having an incorrect score on their permanent records.
