Introduction

The Natural Science 2 Teacher’s Resource Book provides a wide variety of photocopiable worksheets designed to broaden and reinforce the concepts covered in the Natural Science 2 Student’s Book and Natural Science 2 Teacher’s Book.

The worksheets allow a flexible approach in the classroom. Students in the same class can be given different worksheets according to their level: stronger students can expand on the material learnt in class, and students needing more support can use the worksheets to revise when necessary. Students can also work together to complete the tasks with stronger peers. Teachers with more contact hours can make use of the photocopiable materials as and when they need to. They can be used for revision purposes, for extension practice, as progress tests, for assessment or for homework.

There are five categories of worksheets: Reinforcement, Extension, Assessment, Investigate! and Science songs. The Answer keys are provided at the back of the book.

Reinforcement, Extension and Assessment worksheets

There are Reinforcement, Extension and Assessment worksheets for each unit. These worksheets are a flexible tool which can be used after the relevant sections of the Student’s Book.

Depending on the level of the students, they can complete the worksheets with or without consulting their Student’s Books, in the classroom or at home.

There are nine double page Reinforcement worksheets. They are designed to provide additional support for students in need of further practice.

There are nine double page Extension worksheets. They can be used for fast finishers or to further expand on the material covered in class.

There are nine double page Assessment worksheets per unit. These worksheets can be given to students once the unit has been completed, to evaluate progress or as a revision test.
