The Science and Technology curriculum is therefore designed to develop these skills and habits of mind, which are not only directed towards investigating and arriving at plausible conclusions but also towards finding answers to the problems that affect our daily lives.

Thus, science education will develop personal strengths, which can be directed in a properly conceptualised and implemented science programme.
These strengths include; the ability to read, understand and write complete mathematical operations, to develop good communication, interpersonal and intra- personal skills, problem solving skills and critical attitudes to work.

The Curriculum guide has proposed a number of science activities geared towards helping all students develop their personal strengths.
The science and technology activities are also expressed in such a way that they should meet students’ social and psychological needs or recognition, affection, security, belongingness and so on.

Students will demonstrate an awareness of social realities and natural phenomena and their natural curiosity should be tapped and made the prime motivating device in inspiring them to learn about science and technology.
Through the science and technology programme, students will enjoy science as a fun activity which includes artistic experiences, creating projects, carrying out investigations that they plan, taking part in science games and contests, recognizing that recreational activities and sports, example basketball, all have science information for students.

Students involved in science activities will also recognize science as a means of advising them on how to live healthy and safety life styles.
The agriculture strand included in the science and technology programme at every key stage of primary education is an indication that the Ministry sees the critical importance of that industry in our food security policy.
So in order to make sure that our students are given the opportunity to apply science and technological knowledge and skills, to identify and solve practical problems related to the sustainable use of agricultural resources, to facilitate production, distribution and marketing to meet the needs of society, it is worthy that it be included in the science curriculum and not as a separate subject.

The Curriculum guide is organizes in such a way that teachers, students and parents can easily follow it.
In the past it was felt that a process approach was the way forward to an authentic science curriculum guide.

However, we at the curriculum unit have noticed that teachers find it easier teaching from a unit model approach.

The teachers must realise that science needs a lot of preparation if students are to gain the maximum from their efforts.

No longer should we concentrate our efforts on the above average students.
The differentiation of the curriculum in order to address the learning needs of all students should be our foremost goal if we are to comply with the ministry’s vision of quality education for all.

6 The science and technology curriculum was not designed for a textbook but rather for the scientific advancement of all students.
While we all agree that not all students will develop the necessary skills to be doctors and engineers, however, all our students must be given that choice rather than we making that choice for them.

All our students can be equipped with the minimum science skills which can permit them to take part in a day to day conversation on the different natural phenomenon and the way such phenomenon impact their lives.
Thus the strand is further organizes into four broad strands to include; Life Science, Earth and Space Science, Physical Science, and Agricultural science.

It is expected that these strands together with the teachers’ intervention and guidance will equip students with the necessary knowledge and skills needed for the successful completion of the learning programme.

The learning outcomes and success criteria should be seen as a step forward towards a student-centred learning programme.
We are calling on our hard working teachers to become facilitators in the management of the curriculum instead of being the distributors of knowledge.

Students or pupils can play a part in contributing meaningfully to their own learning.

When this is done science becomes exciting, fun, interesting and enjoyable.

We need to stimulate our students’ interest and give them the opportunity to express these without interruption.

This is the way to go.


Only this time, we are clearing the misconceptions rising time and time again.

Science and technology are also linked to all the various subjects within the broader curriculum.

Here we may mention that the scientific process is the preferred approach to investigating problems within the other subjects.

The tools, devices and other gadgets necessary to deliver the other subjects are made possible through the timely inventions of technology.
Science could not be completed without the added contribution of the Social Sciences, Health and Family Life Education, but more so for the direct impact of Mathematics and Language on the scientific development of the students - the former for the measurement and calculation skills and the latter for its broad communication skills which are impacted on all students.

The year summary is broken up into its corresponding term summary, and each is placed at the beginning of each term’s activities.
The term consists of three (3) or more units and each unit consist of the unit title, the learning outcome and the success criteria.

A number of Success criteria have been designed to help students achieve the Learning outcomes and likewise a number of activities have been designed to facilitate the fulfilment of the success criteria.

Teachers are kindly asked to carefully evaluate these activities and to feel free to develop their own activities to facilitate their students’ specific learning needs.
Make use of the various learning opportunities that the Internet affords us, so that our students can be exposed to a wide range of learning opportunities so that their experiences won’t be limited.

It is not an easy task to teach science to students of Grade 2, however we can guide them through, questions and answers, matching answers and colouring objects.

Help them to observe using their senses and to describe what they discover.
As they develop, help them to be excited about the world around them so that they can begin asking questions and give responses.

Remember that their interest in the subject at an early age will help them develop a love for it later.

7 In ending, always seek the most recent information to help your students develop scientifically.

Scientific information is not absolute and may change as we advance because of the advent of new technologies and better approaches.
Dominica is a big, well-equipped laboratory and you are called upon to make use of this God-given (natural) teaching tool.
