tailieunhanh - Lecture Science 1 - Associate Degree in Education: Lecture 29 - Dr. Arshad Bashir

Lecture 29 - States of matter. In this lecture, revisit the concept of state of matter with Students. The first part of the week focus on exploring states of matter and changes of states of matter in hands-on activities. The inquiry provides them with a shared experience to build a foundation for more detailed group and class discussions. In those sessions, you will introduce particle theory and discuss the models of states of matter. | Lecture # 29 SCIENCE 1 ASSOCIATE DEGREE IN EDUCATION STATES OF MATTER STATES OF MATTER In this week, revisit the concept of state of matter with Students.

WATER Have Students carefully observe what happens when an ice cube (if available) or tap water is slowly heated to 100 degrees Celsius. If possible, conduct these activities in small groups rather than as a class demonstration. Also, if available, have them use a thermometer to take measurements throughout the heating process. Then have them record their data points. A note on guiding Teachers’ activities/mini-experiments: some of them may not be comfortable conducting small experiments on their own. If this is the case, provide them with more detailed instructions on how to perform the experiment. Water continue Also, explain how to record the measurements. For instance, you can make it easier by: providing the materials and step-by-step instructions for the procedure assigning roles providing an empty data table to be filled in telling them how often to record the data (for instance, each time they see a change, every 10 seconds, randomly, etc.). Experiments For more advanced Students, keep the instructions open. They then have the opportunity to apply their knowledge and conduct the experiment in an open-ended inquiry fashion. This might take longer than just conducting a demonstration. However, deeper learning takes place in open-ended inquiry to justify the time. Over the course of this semester, strive to give them fewer instructions on how to set up an experiment. They usually embrace the opportunity to work on their own. Also, the resulting discussion among them . | Lecture # 29 SCIENCE 1 ASSOCIATE DEGREE IN EDUCATION STATES OF MATTER STATES OF MATTER In this week, revisit the concept of state of matter with Students.
