Foreword
Eureka! invites you on a voyage of discovery into the world of science and
technology. Like the previous textbook in the series, this one offers a unique
opportunity to explore the plant and animal kingdoms, matter and technology.
After completing the activities in Textbook A, you probably realized why it is
important to study science and technology. When you study science, you are
learning about the whole history of scientific thought and procedure that has
evolved over time. You will want to know more and find answers to important
questions, and you will see the world from a whole new perspective. For example,
you will discover that the Universe is expanding, that water is a precious resource,
that it is possible to slow down climate change and that the planet’s resources
are not unlimited.
As you perform the activities in Textbook B, you will notice the progress you are
making. Your interest in nature will grow, and your observation skills will improve.
You will become more comfortable in describing scientific or technological
phenomena and explaining your findings to your classmates. You will learn how
to solve problems based on a specific reasoning and experimentation process.
Gradually, you will learn to follow the same procedure that scientists have
developed and applied in their search for knowledge. This year, you will learn
about some fascinating topics, such as semi-aquatic environments and the water
cycle. You will also be carrying out some very interesting activities, like preparing
a game show on human development and launching your own perfume.
Eureka! lets you study science by taking part in it, instead of just talking about it.
This series might inspire you to pursue a career in science. In any case, you will
have acquired knowledge and skills that you can apply to other fields too. On
behalf of the entire team, I hope this textbook series will help deepen your
understanding of the amazing world that you share with the other living creatures
around you.
