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.

Amazing frogs and toads! The goliath frog is the biggest frog in the world. It can grow as big as your school bag! It lives in the rainforests in Africa. The goliath frog is an endangered species. One of the smallest frogs in the world is the gold frog. It is only about 1 cm long. It lives in Brazil. It is a carnivore and eats flies, ants and other insects. Some frogs can jump very far. A sharp-nosed frog can jump 10 metres in three jumps! Tree frogs have got sticky toes so they can climb trees easily. Some toads change their skin colour to hide from predators. One of these is the oriental fire-bellied toad. Its belly turns bright red when it is afraid, and it is very poisonous! 1

Space travel Over 50 years ago humans sent the first spaceship into space. Scientists have created many rockets and spaceships to send humans to the Moon and to distant planets. Scientists need to find an energy source for spaceships and satellites when they are in space. They now use solar panels to get electricity from sunlight. Modern satellites have solar panels so their systems and computers work. 1
