5th Grade Science
Common Assessment 4 - Wednesday January 20th
We will be taking a common assessment on Wednesday, January 20th. Students will be doing a review in class on Tuesday and will bring it home to study. Please sign and review paper and return Wednesday with your child. Below are some links to videos and websites that will help with studying, a long with an overview of what will be on the test.
What do students need to know?
- How do sedimentary rocks form: 1. Sediments (small pieces of rock) are weathered off of a rock. 2. The sediments are eroded (carried) and then deposited in a new location. 3. The sediments are compacted together over time and with pressure from above layers of sediment. 4. The layers of sediment are cemented together to form sedimentary rock.
- What are some characteristics that may occur in sedimentary rock? Layers, Fossils, and Fossil Fuels
- How do fossil fuels form: 1. Ancient plants and animals die and are buried between layers of sediment. 2. Over TIME, and with lots of HEAT and PRESSURE, the dead plants and animals become fossil fuels (coal, oil and natural gas).
- How do river deltas form? 1. Sediment is eroded down the river. 2. The river slows at the mouth where it enters the ocean. 3. As the river slows down the sediment settles to the bottom of the river and over time a river delta builds up.
- How do canyons form? Water from fast flowing rivers carve out the canyon over a long period of time through weathering and erosion.
- How do sand dunes change? Sand dunes can change quickly due to wind erosion
- What are some ways that Earth's surface can change quickly? 1. Volcanoes can build up land when lava cools and hardens into rock. 2. Landslides change Earth's surface when there has been too much rain and a mass of Earth's surface slides down the side of a cliff/hill. 3. Earthquakes
- What are fossils and what can they tell us about past environments? Fossils are evident of past living organisms. They give us clues about the past such as what was the environment like (land, water, forest, etc.) and they give us clues about the animals.
