Alabama Course of Study · from Gradelings · Name: ______________________
Question 1
When two cars bump, you hear a sound. The sound shows…
- energy grew
- some energy turned into sound
- nothing happened
- energy disappeared
some energy turned into sound
Hint: Energy changes form.
Question 2
When you eat a meal, you get energy from…
- food
- air only
- water only
food
Hint: Food is fuel for bodies.
Question 3
In a hydroelectric station, which is the correct chain of energy changes?
- Gravitational potential → kinetic → electrical
- Light → sound → electrical
- Electrical → kinetic → chemical
Gravitational potential → kinetic → electrical
Hint: Water high up flows down (kinetic) and spins a turbine that makes electricity.
Question 4
Waves at the beach can move…
- mountains in a day
- the sun
- sand and pebbles
- the moon
sand and pebbles
Hint: Waves carry energy.
Question 5
A fire alarm uses a loud, high-pitched sound. Why?
🚨- it is pretty
- it is quiet
- it is easy to notice and warns people of danger
- it makes the fire go out
it is easy to notice and warns people of danger
Hint: Sound is a useful warning signal.
Question 6
Too many outdoor lights at night can confuse…
🐦- worms
- polar bears
- migrating birds
- fish in deep oceans
migrating birds
Hint: Some cities turn off lights during bird migration.
Question 7
Cactus spines are a kind of…
- flower
- seed
- leaf
- root
leaf
Hint: Narrow leaves lose little water.
Question 8
Which animal has fur that changes color with the seasons?
- snowshoe hare
- frog
- robin
snowshoe hare
Hint: It's brown in summer and white in winter.
Question 9
You touch a hot pan by accident. Put this fast reflex in order.
- 🧠Your brain notices: "Ouch, hot!"
- ⚡A message zips to your spinal cord
- 💪Arm muscles pull your hand away
- ✋Nerves in your skin sense the heat
- ↩️Your spinal cord sends a message right back
Nerves in your skin sense the heat → A message zips to your spinal cord → Your spinal cord sends a message right back → Arm muscles pull your hand away → Your brain notices: "Ouch, hot!"
Hint: A reflex is a shortcut! The message goes to your spinal cord and straight back to your muscles. Your brain notices the pain a moment later.
Question 10
A warm front is when…
- warm air moves over cooler air
- winds stop
- cold air pushes under warm air
warm air moves over cooler air
Hint: The warm air slides up over the cold air.
Answer key
- 1. some energy turned into sound (Energy, Speed & Collisions)
- 2. food (Energy on the Move)
- 3. Gravitational potential → kinetic → electrical (Forms of Energy)
- 4. sand and pebbles (Waves & Codes)
- 5. it is easy to notice and warns people of danger (Sound)
- 6. migrating birds (Light)
- 7. leaf (Built to Survive: Plants)
- 8. snowshoe hare (Adaptations & Habitats)
- 9. Nerves in your skin sense the heat → A message zips to your spinal cord → Your spinal cord sends a message right back → Arm muscles pull your hand away → Your brain notices: "Ouch, hot!" (Sense & Respond)
- 10. warm air moves over cooler air (Weather and the Water Cycle)
