University of Example: Grade 4 Science Light Interaction Assessment

This assignment assesses a Grade 4 student's understanding of how light interacts with different materials. The assessment focuses on the concepts of opaque, translucent, and transparent materials, and how they affect the creation of shadows. The student is tasked with describing what happens when light encounters a hardboard, a tinted glass window, and a clear glass. The assessment includes a drawing component, where the student illustrates the interaction of light with each material, and a written component, where the student describes the interaction. The assignment is designed to evaluate the student's comprehension of light's properties, its ability to travel in straight lines, and how different materials affect its path. The teacher provides feedback to guide the student and evaluate the student's performance based on the learning outcomes and success criteria, ensuring a comprehensive understanding of the topic.

Grade: 4
Strand: Physical World
Learning outcome(s)
to be assessed: 4PW2: Describe the interaction of light with different materials.
Lesson Outcome: Describe the interaction of light with opaque, translucent and transparent
materials.
Type of Assessment:
Rationale:
Background:
The student took this lesson on how light travels at different materials. The main lesson on this topic
was to learn about shadow, how to create sharp, dark and colored shadows. In addition, the students
learnt that light only travel in straight line and thus can describe its interactions with different materials
such as opaque, translucent and transparent ones. This was a second lesson at the class activity. Since
the students have already discussed with the teacher on this topic, it will be an easy activity for them.
Additionally, the student are familiar with this type of assessment since they carry it frequently after
any experiment or investigation.
Delivery method:
An activity will be presented to the student after investigation. The teacher will read the questions to
the students and explain them if need be. The teacher will then explain the success criteria upon which
the student will be assessed. The students will carry out the task individually, describing how light is
able to interact with different materials. They will be able to draw the light lines and write sentence
which describes their drawings. The teacher will walk around scaffolding the students during the
assessment.
Validity:
The main aim of the assessment is to check whether the student have mastered the outcome of the

lessons. The assessment will test the comprehensiveness of the students and their ability to understand
the lessons learning outcome. The assessment is valid since it requires the student to describe how light
interacts with opaque, translucent and transparent materials. By drawing and describing their drawings,
the students will state how light interacts with those materials to match the outcome.
Feedback:
During the assessment, the teacher will provide the feedback. This feedback will be meant to help the
students during the assessment. For instance a assessment like “Ahmed, make sure that you use the
scientific terms” will ensure the student focuses on the teacher comment. In addition, after the
assessment the teacher will provide feedback on each students paper. This feedback will show the
student how they performed and how they can improve referring to the learning outcome and success
criteria. Lastly, the teacher will provide oral feedback to the students highlighting the challenges which
many student faced during the assessment.
Defense
This assessment was made to be an individual task to help gauging the student as well as providing
them the keywords to use in box and picture drawing in describing light interaction. Pictures and
drawings are uses more since they are still young to write.
8 How light travels
Name:
Grade:
Date:
What happens when light hits a hardboard?

A dense shadow is created since light cannot pass through.
What happens when light hits a tinted glass window?
Light shadow is created since little amount of light penetrated
through the glass.
What happens when light hits a clear glass?
No shadow is created since all light is able to penetrate through
the glass.
