Developing Students' Understanding of Day and Night Changes and Celestial Bodies

Part 1
It is suggested that everyone has their own non scientific ideas therefore students also have
their ideas about the natural phenomenon sun, moon and Earth which they have developed
through everyday interactions. They also have other perception as how day changes into
night and vice versa. This unit work will aim to develop the students prior knowledge about
how day and night is caused by the rising and setting of the sun. Students will develop the
knowledge as how revolution of the Earth around the sun causes regular changes as night
and day and to acquire the knowledge about the size, shape and location of the celestial
bodies which is planets, moon, sun starts. As the changes in Shadow during whole day are
identified and connected to the movement of the sun in the sky (Australian Academy of
Science, 2013). This work will cover the total six chapters in which some include the
student-directed investigation based on the 5Es learning model for teaching science. This
process will make the student able to develop a deep concept about the science subject
through which hey will indulge into the findings and research that will be connected to the
real life experiences that will enable them to ask queries and answer the questions.
-ended questions (National Aeronautics and Space Administration [NASA], 2013).
Part 2
As the diagnostic assessment will obtain during chapter one in the Engage phase. This
assessment is used to develop the students prior knowledge on topic as how rotation of the
earth on its axis drives the changes on regular basis which involves the day and night
changes (Australian Academy of Science, 2013). then the current understanding of the
student over the topic will be used as to develop the proper learning patterns for both
Exploring and describing the phases of this unit of work. The diagnostic assessment will
obtain from the T-chart in which the invigilator gathers and students notes down the current
ideas and knowledge from the class brain storm. Due to this brainstorm students will able
to share what their opinion is about the changes of nights and days and this knowledge can
be see through the questions.
Part 3
As the Formative assessment will happen by finding and to describing the phases. This
assessments will be used as to analyze and to track the student as they are developing
knowledge about the scientific topic and which also enable the educator to provide the
