New York State Learning Standards · from Gradelings · Name: ______________________
Question 1
You touch a hot pan by accident. Put this fast reflex in order.
- 💪Arm muscles pull your hand away
- ↩️Your spinal cord sends a message right back
- 🧠Your brain notices: "Ouch, hot!"
- ⚡A message zips to your spinal cord
- ✋Nerves in your skin sense the heat
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 2
Which surface reflected the most light?
Temperature after 10 minutes in the Sun (°C) - white paper
- foil
- black paper
foil
Hint: It stayed the coolest.
Question 3
Is the sound high or low in pitch? Tap an item, then tap its basket.
Sort into: 🔼 high pitch · 🔽 low pitch
- 🐻a bear's growl
- 🪈a whistle
- 🎺a tuba
- ⛈️thunder
- 🐦a bird chirp
- 🎶a piccolo
🔼 high pitch: a whistle, a bird chirp, a piccolo · 🔽 low pitch: a bear's growl, a tuba, thunder
Hint: Small, short, tight things vibrate fast and make a high pitch. Big, long, loose things vibrate slowly and make a low pitch.
Question 4
Which is a body-part adaptation?
- A bear hibernating
- A rabbit's long ears
- A bird migrating
A rabbit's long ears
Hint: Body parts are physical features.
Question 5
Which sense helps you notice smoke from a fire?
- taste only
- smell
- hearing only
smell
Hint: Smoke has a scent.
Question 6
Which has the most energy of motion?
- A truck going fast
- A bike parked
- A truck parked
- A ball resting
A truck going fast
Hint: Moving and heavy.
Question 7
The distance from one wave top to the next is the…
- depth
- wavelength
- amplitude
- volume
wavelength
Hint: Crest to crest.
Question 8
Big boulders sit in New York fields far from where they formed. They were moved by…
- volcanoes
- raindrops
- birds
- glaciers
glaciers
Hint: Ice sheets carried them.
Question 9
A tsunami is a…
- giant ocean wave
- strong wind
- snowstorm
- kind of volcano
giant ocean wave
Hint: Often caused by an earthquake.
Question 10
Which uses sunlight to make electricity?
- Solar panel
- Wind turbine
- Dam
- Gas stove
Solar panel
Hint: Panels face the sun.
