Learners are expected to understand the many types of spirits and regional techniques used to make alcohol. There will be physical and chemical interactions that students must pay close attention to. The students will conduct a water-based control experiment and then track the results. The students will take notes as the tests are being administered. These will be noted and used when drafting the experiment's final report. The experience will be commenced to pupils at grade four. There are several factors to be taken into justification. These include students’ ability to learn, available learning materials, and the classroom settings. Basically, the experiment will be conducted in an open environment especially outside the classrooms.. Alternatively, the experiment can be undertaken in a well-ventilated laboratory setting. However, the experiment will be exclusively conducted in children without learning impairment involving vision and hearing.
National / State Learning Standards:
The relevant grade level standard(s) for the learners for them to comprend practical skills in the upper grade A+, A, B and finally grand C
Specific learning target(s) / objectives:
At the end of the science fair, learners need to;
Understand the concept of physical and chemical changes
Explain the reaction process leading to production of the Methanol
Discuss the principles behind uses of yeast as a catalyst
Teaching notes:
The lesson is categorized under the study of Physical and Chemical reactions. Reactions of methanol as a basis of the experiment
Agenda:
The class begins with an introduction of Methanol. Learners then get insights on the reaction process between the acid and yeast. Pupils are expected to observe and record their findings from the experiment. Finally, the pupils reflect on the physical and chemical changes by observing the control
Formative assessment:
Questions regarding physical and chemical changes will be availed in the study groups to test the lesson understanding. Learners will be expected to explain the examples of physical and chemical reactions common in their area.
Academic Language:
English
Key vocabulary:
Reaction
Physical changes
Experiment
Methanol
Enzyme
Catalyzed
Chemical changes
Control experiment
Function:
The language aims to foster understanding of concepts involved in the science fair project. Intrinsically, simple English will be used mainly when describing key terms used during the lessons. The knowledge of these key terms will be based on the assessment of the key terms used in the experiment. This will form part of the evaluation studies.
Form:
The aim of the science fair will be to enhance the understanding of both physical and chemical reactions. As such, organization of language will start from known to unknown concepts. The language will also begin from simple to complex. The learners will be asked if they are familiar with apparatus and reagents used in the experiment.
Instructional Materials, Equipment and Technology:
Methanol , solutions, four bottles, , funnel, and water
Grouping:
The nature of pupils will be categorized accordingly. This will be based on the learners ability to learn. Pupils that have the ability to grasp information faster will be categorized in the groups of Fast Learners. On the other hand, pupils have slower learning abilities will be grouped as Slow Learners. The instruction methods used for these categories will be different so as to enhance the understanding of the science fair concepts.
II. Instruction
A. Opening
Prior knowledge connection:
This lesson will complement the class studies on the reactions of both the chemical and physical components. In addition, it expounds on the study of the properties of matter methanol.
Anticipatory set:
Let the learners assemble in the classroom prior to the science fair. Explain the uses of the duo for the science fair experiment.
B. Learning and Teaching Activities (Teaching and Guided Practice):
I Do
Students Do
Differentiation
The experiment will be introduced to the pupils. The set-up will be arranged by the teachers and later pupils allowed to arrange on their in the study groups. Carry out the procedures of the experiments systematically to enhance understanding of concepts to the pupils. Allow the learners to make observations during the experiment. Explain the concepts of chemical and physical reactions
Initially, the pupils need to make observations on how the experiment is arranged and the outcome. Thereafter, the students should be ready to prepare their experiments based on the explanations from the teacher. They need to record the observation made and write a report on the same.
Priority will be given to students with slow learning abilities. They will be encouraged to participate in the experiment by use of familiar objects such as toys. On the other hand, students who are fast learners
III. ASSESSMENT
Summative Assessment:
The learners are assessed based knowledge on the principles of the experiment. They will be evaluated on the methodology of the experiment, observation and the ability to draw a succinct conclusion of the experiment. Participation of each pupil in the group discussion will also be important especially during the entire period of the experiment.
Differentiation:
The experiment banks on the observation of color change. As such, the experiment does not favor learning for pupils with hearing and visual challenges. Besides, assessment of understandings for these pupils will come with challenges.
Closure:
In wrapping up the lesson, allow the pupils to brainstorm on the concept of physical and chemical reactions. To achieve these, ask questions regarding the topics learned. Allow them to ask questions on concepts not clearly understood.
Homework:
Homework is part of the evaluation process to the learners. Provide homework on the examples of chemical and physical changes. The task is supposed to be done at home with the support of the guardian. The homework is part of the skill development and therefore will be assessed at the end of the term exams. Precisely, the homework is aimed at developing the observation skills of the learners. Moreover, it allows the learners to develop critical and creative skills. Therefore, a worksheet will be availed to the learners where they will do the assignments given to them.
