Cause & Effect — Answer Key
Part A: Sort the Words
Sort each word or number into the correct category box.
1. Sort each nature sentence part as a Cause or an Effect.
Cause
Snow fell all nightDark clouds rolled inThe hot sun shone on the iceStrong wind blew through the yard Effect
The kids got out their sledsMaya opened her umbrellaThe puddle grew biggerLeaves flew off the tree In nature, one event often makes another event happen right after it, so we look for what came first.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. It rained all morning, so the garden got wet.
Rain falling on the garden is the cause, and the garden getting wet is the effect.
2. The sun melted the snowman because it was hot.
Hot sunshine is the cause that makes frozen snow turn back into water.
3. Leaves fell from the tree because the wind blew.
Strong wind pushes on leaves and that force makes them drop or fly away.
4. A rainbow appeared after the rain stopped.
When rain ends and sun returns, light bends in water drops and makes a rainbow.
5. The pond froze because the weather got very cold.
Cold air pulls heat from the water until it freezes into solid ice.
Part C: True or False?
Read each statement. Circle True or False.
1. Snow on a hill can cause kids to go sledding.
True False
Snow is the cause because sleds slide only on snowy ground, so the snow leads to sledding.
2. An umbrella causes the rain to start falling.
True False
Rain comes first and makes people open umbrellas, so the umbrella is the effect, not the cause.
3. Hot sunshine can cause ice cubes to melt.
True False
Sun gives off heat, and that heat is the cause that makes solid ice turn into water.
4. A strong wind has no effect on loose leaves.
True False
Wind pushes loose leaves and lifts them off the ground, so wind clearly has an effect.
