How to use this book

Welcome to Hodder Education’s MYP by Concept series! Each chapter is designed to lead you through an inquiry into the concepts of MYP Sciences, and how they interact in real-life global contexts.

KEY WORDS

Key words are included to give you access to vocabulary for the topic. Glossary terms are highlighted and where applicable, search terms are given to encourage independent learning and research skills.

As you explore, activities suggest ways to learn through action.

ATL

•  Activities are designed to develop your Approaches to Learning (ATL) skills.

Assessment opportunities in this chapter:

Some activities are formative as they allow you to practise certain parts of the MYP Sciences Assessment Objectives. Other activities can be used by you or your teachers to assess your achievement against all parts of an assessment objective.

Key Approaches to Learning skills for MYP Sciences are highlighted whenever we encounter them.

Hint

In some of the Activities, we provide Hints to help you work on the assignment. This also introduces you to the new Hint feature in the on-screen assessment.

Information boxes are included to give more detail and explanation.

EXTENSION

Extension activities allow you to explore a topic further.

Take action

•  Guidance is given throughout the book about how to apply your knowledge of the scientific process to real-life situations. While the book provides many opportunities to apply the knowledge you have learned in practical ways, you must be an active part in this process. Activities help you explain the ways in which science can be applied and used, and also to discuss and evaluate the implications of using scientific principles to address specific issues. This should give you a better understanding of the issues facing scientists in the twenty-first century. By engaging in these activities, you will also learn the value of consistently applying scientific language to communicate understanding clearly and precisely.

You are prompted to consider your conceptual understanding in a variety of activities throughout each chapter.

Links to:

Like any other subject, MYP Sciences is just one part of our bigger picture of the world. Links to other subjects are discussed.

We will reflect on this learner profile attribute …

•  Each chapter has an IB learner profile attribute as its theme, and you are encouraged to reflect on these too.

Finally, at the end of the chapter you are asked to reflect back on what you have learned with our Reflection table, maybe to think of new questions brought to light by your learning.
