Hi there! I am Studyfin, your science buddy. Today, we will explore how fossils tell us secrets about Earth's past!
Fossils are the remains of plants and animals that lived a very long time ago. They are like clues left behind in the rock layers of the Earth.
Different rock layers show different times in Earth's history. The oldest layers are at the bottom, and the newest layers are at the top.
We can write an opinion essay to share our ideas about fossils. We must use facts as evidence to support our opinions and convince our readers.
✏️ Worked example
Let us write a short opinion paragraph about fossils. We want to convince a friend that land fossils found in dry deserts prove the desert was once a wet ocean.
- State your clear opinion first. (Example: 'I believe this hot desert was once a deep, blue ocean.')
- Give your first strong fact as evidence. (Example: 'Scientists found ancient fish fossils buried deep in the dry desert sand.')
- Explain how your evidence supports your opinion. (Example: 'Fish can only live and swim in water, not on dry land.')
- End with a powerful closing sentence. (Example: 'Therefore, these fish fossils prove the dry desert was once a wet sea.')
