Why are New Zealands plants and animals so special? What forces are shaping the land even as we watch? Where does our petrol come from (and why is it so expensive)? How does a camera work? Why does the sun shineand how long will we be able to depend on it? For New Zealanders to be informed citizens of a modern country, everyone needs an understanding of the basic science behind daily life. Now that Level 2 Science Achievement Standards offer students credits towards their NCEA at Level 2 or Level 3, everyone can find a place for Science in their senior years of secondary school! The Year 12 Science Workbook covers the content needed for AS9031490317, with questions to help students assess their own learning and understanding, including six NCEA-style practice tests. There is a glossary of words which will be particularly useful for readers who have English as a second (or third) language, and a full set of answers.
