Unit Checkpoint: Habitats Review

Review: What We Learned

Congratulations! You have finished the Habitats unit. Let's review everything you learned before taking the checkpoint quiz.

Key Vocabulary

Word	Meaning
Habitat	A place where animals and plants live
Forest	A habitat with many trees
Ocean	A large body of salt water
Shelter	A safe place to live and hide
Data	Information we collect
Tally chart	A way to count using marks
Graph	A picture that shows data
Claim	What you think (your answer)
Evidence	Facts that support your claim
Reasoning	Explains why evidence proves your claim

Big Ideas to Remember

All animals need four things: food, water, shelter, and space
Different habitats provide what different animals need
Scientists investigate by observing carefully and asking questions
Data and graphs help us organize and understand information
CER writing helps us explain our scientific thinking

Habitats We Studied

Forest: Squirrels, deer, birds, rabbits - lots of trees and plants
Ocean: Fish, crabs, whales, seahorses - salt water everywhere
Other habitats: Ponds, deserts, meadows, arctic

Review Examples

Example: Matching Animals to Habitats

Think about what each animal needs. Does the habitat provide it?

Animal	Best Habitat	Why?
Polar bear	Arctic (cold)	Has thick fur for cold, hunts seals on ice
Clownfish	Ocean coral reef	Needs salt water and hides in coral
Owl	Forest	Lives in tree holes, hunts mice at night
Frog	Pond	Needs water to lay eggs and stay moist

Example: Using Data

A scientist counted animals at a pond:

Frogs: |||| ||| (8) Ducks: |||| (5) Turtles: ||| (3) Fish: |||| |||| || (12)

Most animals: Fish (12)
Fewest animals: Turtles (3)
Total animals: 8 + 5 + 3 + 12 = 28

Example: Complete CER

Question: Is a pond a good habitat for a frog?

Claim: I think a pond IS a good habitat for a frog.

Evidence: Ponds have water for frogs to swim. Ponds have insects for frogs to eat. Lily pads and plants give frogs places to rest and hide.

Reasoning: This proves my claim because frogs can find food, water, shelter, and space in a pond. A pond gives frogs everything they need to survive.

Part 4: Extended Response

12. Write a complete CER to answer this question: "Can a fish live in a forest habitat?"

Claim: (What do you think? Can a fish live in a forest?)
Evidence: (What do you know about fish? What do forests have or not have?)
Reasoning: (Why does your evidence prove your claim?)

Answer Key

Answers 1-4 (Habitat Basics):

Show Answers

B - A place where animals live
C - Food, water, shelter, space
B - Dolphin
C - Shelter

Answers 5-8 (Investigations and Data):

Show Answers

B - Observes carefully and asks questions
C - 7 (five marks crossed, plus two more)
A - Birds (10 is more than 7 or 4)
B - To see patterns and compare data

Answers 9-11 (CER Writing):

Show Answers

B - Claim, Evidence, Reasoning
A - Claim
B - Evidence (it describes something observed)

Sample Answer for Question 12:

Show Sample Answer

Claim: I think a fish CANNOT live in a forest habitat.

Evidence: Fish need water to breathe through their gills. Fish need water to swim. Forests do not have enough water - they have trees, soil, and land.

Reasoning: This proves my claim because fish cannot get the water they need in a forest. Without water, fish cannot breathe or move, so they cannot survive in a forest habitat.

What's Next?

Celebrate! You finished the Habitats unit!
Review any lessons where you missed questions
Keep observing animals and their habitats in real life
Move on to the next Science unit when you're ready

Great Job, Scientist!

You learned about habitats, how to investigate like a scientist, how to collect data, and how to explain your thinking with CER. These are skills you will use again and again in science!
