Arizona Academic Standards · from Gradelings · Name: ______________________
Question 1
A group of similar cells working together forms a…
- organelle
- tissue
- molecule
- organism
tissue
Hint: Like muscle tissue.
Question 2
What is a reflex?
- a slow decision you plan carefully
- a type of bone in the arm
- a hormone made by the kidneys
- a fast, automatic response you don't have to think about
a fast, automatic response you don't have to think about
Hint: Blinking when something flies at your eye is a reflex. It happens before you can think about it.
Question 3
How many senses do people usually talk about?
- three
- two
- five
- ten
five
Hint: They are sight, hearing, smell, taste and touch.
Question 4
A dandelion has one thick, deep root that goes straight down. What kind of root is this?
- A stem root
- A fibrous root
- A flower root
- A taproot
A taproot
Hint: A taproot is a single main root; a fibrous root system is a mass of thin roots.
Question 5
A 2 kg object accelerates at 3 m/s². What force acts on it?
- 9 N
- 1.5 N
- 6 N
- 5 N
6 N
Hint: F = 2 × 3.
Question 6
What happens to an electromagnet when you disconnect the battery?
- it turns into a bulb
- it melts
- it gets stronger
- it stops being a magnet
it stops being a magnet
Hint: The current stops.
Question 7
South America and Africa fit together like puzzle pieces. This supports…
- photosynthesis
- gravity
- continental drift
- the water cycle
continental drift
Hint: Shapes match.
Question 8
Which tool measures wind speed?
- anemometer
- rain gauge
- barometer
anemometer
Hint: Cups on an anemometer spin faster in stronger wind.
Question 9
Which part controls the cell's activities?
- Cell wall
- Nucleus
- Vacuole
- Chloroplast
Nucleus
Hint: It holds the DNA.
Question 10
Which body system does each part belong to? Tap an item, then tap its basket.
Sort into: ⚡ nervous system · 🚰 excretory system · 🧪 endocrine (hormone) system
- 🧵ureters
- 🦋thyroid gland
- 🔗spinal cord
- 🎈bladder
- 〰️nerves
- 🎛️pituitary gland
⚡ nervous system: spinal cord, nerves · 🚰 excretory system: ureters, bladder · 🧪 endocrine (hormone) system: thyroid gland, pituitary gland
Hint: The nervous system carries fast electrical messages. The excretory system removes wastes. Endocrine glands release hormones into the blood.
