Day 41: Shapes of Land

Standard: Grade 2 Science Standard 8, 2.8

Practice record: Landforms, printed on the Week 9 Practice Workbook.

Worked example: What is the low land between two mountains called? Worked answer: A valley.

1. A plain.
2. Cheaha Mountain.
3. Both are raised land. A mountain is much higher and has steeper sides; a hill is lower and rounder. Accept one likeness and one difference.

Teaching note: Use your hand: a fist for a hill, a raised hand with fingers up for mountains, the space between fingers for valleys, and a flat palm for a plain.

Day 42: Bodies of Water

Standard: Grade 2 Science Standard 8, 2.8

Practice record: Bodies of water, printed on the Week 9 Practice Workbook.

Worked example: What is the difference between a lake and an island? Worked answer: A lake is water surrounded by land; an island is land surrounded by water.

1. The ocean.
2. A river.
3. An island is land with water all around it, so Dauphin Island must have water on every side. Accept any answer using the meaning of island.

Teaching note: Fill a pan with water and place a rock in the middle to show an island.

Day 43: Build a Landform Model

Standard: Grade 2 Science Standard 8, 2.8

Worked example: In a model, where should a river go: on top of a mountain or through a valley? Worked answer: Through a valley.

1. The mountain.
2. Answers vary, but the water should be in a low place, such as a valley or plain.
3. The water runs down the sides of the mountain into the valley or low places. Water flows downhill. Accept any answer describing downhill flow, based on what the child saw.

Teaching note: Use a tray with sides for the water test. Use the observation checklist below.

Hands-on task observation checklist (Build a landform model). Check each item you observe. Four or five items shows the child met the task goal; two or three means repeat the task with support.

• ☐ Child drew a plan before building.
• ☐ The model shows a mountain that is higher than a hill.
• ☐ The model shows a valley between raised land and a flat plain.
• ☐ The model includes a body of water.
• ☐ Each part is labeled correctly.

Day 44: Reading a Map of Land and Water

Standard: Grade 2 Science Standard 8, 2.8

Practice record: Map key, printed on the Week 9 Practice Workbook.

Worked example: On a map, a key shows a wavy blue line for River. What does a wavy blue line on the map stand for? Worked answer: A river.

1. A mountain.
2. Blue.
3. A river starts near a mountain and flows down to a lake or the ocean. Water flows from high land to low places. Accept any answer that reads the symbols and describes the river flowing to the lake or ocean.

Teaching note: Look at a real map of Alabama together. Find the Tennessee River and the coast.

Day 45: Independent Check: Land and Water

Standard: Grade 2 Science Standard 8, 2.8

Practice record: Map description, printed on the Week 9 Practice Workbook.

Worked example: What is land with water all around it? Worked answer: An island.

1. A valley.
2. A lake (the blue area).
3. The river starts between the mountains, which are high, and runs across the plain to the lake, which is low. Water flows from high places to low places. Accept any answer about flowing downhill.

Teaching note: Independent check: read the map description aloud if needed, but give no hints.
