Social Studies
Objective: I can name bodies of water and tell how they are different.
Standards: D2.Geo.5.3-5, D2.Geo.2.3-5
Builds on: Needs Day 1 landforms and Week 3 map keys. One-minute check: ask, "Which landform is low land between mountains?" (A valley.)
- ocean – a huge body of salt water
- sea – salt water that is smaller than an ocean and partly surrounded by land
- river – fresh water that flows across the land in a long path
- stream – a small river
- lake – a large body of water with land all around it
- pond – a small, shallow lake
- fresh water – water that is not salty
- evidence – words, numbers or a place on a map that you can point to, to show an answer is true
Materials: Notebook, Pencil, Blue crayon, A U.S. or world map, 1 baking tray, 1 thick book, 2 clear cups with half a cup of drinking water in each, Half a teaspoon of salt, 1 spoon
- Day 17 — Bodies of Water — Big Question Warm-Up · 5 min
Spaced review from Week 3. Ask: "On a map key, what does the color blue usually stand for?" (Water.) Then ask the day's wonder: "Where does the water in a river come from, and where is it going?" Take every idea.
- Mini-Lesson · 10–15 min
Say: "Water on Earth has different names. The name depends on size, on salt, and on whether the water flows." Rest one end of the tray on the book. Slowly pour the water from one cup onto the high end. Say: "Watch. This water flows downhill in a path. Flowing fresh water is a river. A small river is a stream." Point to the pool at the low end. Say: "This water stays in one place with land around it. That is a lake. A small, shallow lake is a pond." Stir the salt into the second cup with the spoon. Your child may taste one drop on a fingertip. Say: "An ocean is a huge body of salt water. Earth has five oceans. They are the Pacific, Atlantic, Indian, Arctic and Southern. A sea is salt water too. It is smaller than an ocean and partly surrounded by land." Ask: "Which flows, a river or a lake?" (A river.) "Which is bigger, a stream or a river?" (A river.) "Why can we not drink ocean water?" (It is too salty.) If stuck, say: "Ask two things. Is it salty or fresh? Does it flow or stay?"
- Activity / Source Work · 15–20 min
Map and chart work. 1) On the map, your child finds the Pacific Ocean, the Atlantic Ocean, the Great Lakes and the Mississippi River. 2) Your child traces the Mississippi with a finger from north to south. Say: "Evidence is what you can point to that shows your answer is true." Ask: "Where does this river end? What is your evidence?" (It ends at the salt water south of Louisiana. The blue line stops there.) Say: "Rivers flow from higher land down to a lake or an ocean." 3) In the notebook, draw a chart with three columns. Head them Water, Salt or fresh, and Flows in a path. List the six water words down the side. Your child fills in each row in pencil. Expect these answers. Ocean: salt, no. Sea: salt, no. River: fresh, yes. Stream: fresh, yes. Lake: mostly fresh, no. Pond: fresh, no. 4) Find the water nearest your home on the map and name its kind.
- Notebook Entry · 10 min
Your child draws and labels the six bodies of water with the blue crayon. Then your child finishes this frame. "A ____ is different from a ____ because ____." Sample: "A river is different from a lake because a river flows and a lake stays."
- Wrap-Up & Exit Ticket · 5 min
Read the three exit questions aloud. Your child may look at the chart for question 2 only. Praise answers that use the words salt, fresh or flows.
Watch for: Thinking any very large water is an ocean.
Try: Ask, "Is it salty? Is there land all around it?" Lake Michigan is huge, but it is fresh and has land around it.
- Which is bigger, a pond or a lake?
- Name the two kinds of water that flow in a path across the land.
- Lake Superior is so wide that you cannot see across it. Why is it still a lake and not an ocean?
Show answers
- A lake.
- A river and a stream.
- It has land all around it and its water is fresh. An ocean is salt water.
Support: Sort only three words today: ocean, river and lake. Your child says salty or fresh, then flows or stays, for each.
Extend: Your child finds the longest river or largest lake in your state on a map. Then your child names one town beside it.
Homework: Your child finds one river or lake on a map of your state and tells a family member its name. Look for the right word, river or lake.
