科学是可以被修正的
Science Can Be Revised
科学知识是暂时的——它是基于现有证据的最佳解释；当更好的证据出现时，科学可以也应该进行修订。
Scientific knowledge is provisional — it is the best current explanation based on available evidence, and it can and should be revised when better evidence arrives
学习证据 / Evidence
- 举出一个科学观点因新证据而改变的例子，例如人们曾以为太阳绕着地球转。
- 解释科学家在实验出现意外结果时会更新自己的想法，这是一种优点而不是缺点。
- 说明为什么持续检验想法很重要，而不是仅仅因为专家这么说就接受它们。
- Give an example of a scientific idea that changed when new evidence was found — e.g. people once thought the Sun orbited the Earth
- Explain that scientists update their ideas when experiments give unexpected results, and that this is a strength not a weakness
- Describe why it is important to keep testing ideas rather than just accepting them because an expert said so
评估问题 / Assessment
{{name}}是否明白，随着新发现的出现，科学事实可能会被修正——而且这正是科学正常运作的表现，而不是说明科学家以前错了？
Does {{name}} understand that scientific facts can be revised as new discoveries are made — and that this is science working properly, not a sign that scientists were wrong?
