Question 1
Put the parts of the digestive system in the order food travels through them.
- 🌀Stomach: acid and juices churn the food
- 🩸Small intestine: nutrients pass into the blood
- 💧Large intestine: water is absorbed
- 👄Mouth: teeth chew and saliva mixes in
- ⬇️Esophagus: muscles squeeze food down
Mouth: teeth chew and saliva mixes in → Esophagus: muscles squeeze food down → Stomach: acid and juices churn the food → Small intestine: nutrients pass into the blood → Large intestine: water is absorbed
Hint: Food is chewed in the mouth, squeezed down the esophagus, churned in the stomach, then moves through the small intestine and finally the large intestine.
Question 2
Put the steps of bending your arm in order.
- 🧠The brain sends a signal to the biceps
- 💪The biceps contracts (gets shorter)
- ↪️The arm bends at the elbow joint
- 🦴A tendon pulls on a forearm bone
The brain sends a signal to the biceps → The biceps contracts (gets shorter) → A tendon pulls on a forearm bone → The arm bends at the elbow joint
Hint: Your brain sends the message first. Then the biceps contracts, its tendon pulls the bone, and the arm bends at the elbow joint.
Question 3
Kenji has a dry mix of iron filings, sand and salt. Put his separation steps in order.
- 🥄Add water and stir until the salt dissolves
- ☀️Let the water evaporate to leave the salt
- 🧲Run a magnet through the dry mix to pull out the iron
- ☕Pour it through a filter to catch the sand
Run a magnet through the dry mix to pull out the iron → Add water and stir until the salt dissolves → Pour it through a filter to catch the sand → Let the water evaporate to leave the salt
Hint: Use the magnet while the mix is still dry. Then dissolve the salt, filter out the sand, and evaporate the water to get the salt back.
Question 4
These ramps all lift a box to the same height. Order them from LEAST force needed to MOST.
- 📐4 m ramp
- 📐2 m ramp
- 📐5 m ramp
- 📐1 m ramp
5 m ramp → 4 m ramp → 2 m ramp → 1 m ramp
Hint: For the same height, a longer ramp is gentler, so it needs less force. The trade-off: you push the box a longer distance.
Question 5
Put the steps that make sedimentary rock in order.
- 🌊Erosion carries the pieces away
- 🟫The sediment settles in layers
- 🌧️Weathering breaks rock into small pieces
- 🪨Layers are pressed and cemented into rock
Weathering breaks rock into small pieces → Erosion carries the pieces away → The sediment settles in layers → Layers are pressed and cemented into rock
Hint: First rock breaks down (weathering), then the pieces are moved (erosion), dropped in layers (deposition), and finally pressed and cemented together.
Question 6
How do fossil fuels form? Put the steps in order.
- 🌿Ancient plants and tiny sea creatures live and die
- 🛢️They slowly become coal, oil or natural gas
- 🟫Their remains are buried under layers of sediment
- 🔥Heat and pressure act on them for millions of years
Ancient plants and tiny sea creatures live and die → Their remains are buried under layers of sediment → Heat and pressure act on them for millions of years → They slowly become coal, oil or natural gas
Hint: Living things died, were buried, and then heat and pressure acted on them over millions of years.
Question 7
Which organ absorbs most of the nutrients from food into the blood?
- the stomach
- the large intestine
- the small intestine
- the esophagus
the small intestine
Hint: The small intestine is long and lined with tiny finger-like bumps that pass nutrients into the blood.
Question 8
Where is a good place to feel your pulse?
- on your fingernail
- on your kneecap
- on the tip of your nose
- on the inside of your wrist
on the inside of your wrist
Hint: You can feel your pulse where an artery is close to the skin, like the inside of your wrist or the side of your neck.
Question 9
What is a solution?
🧪- a mixture that looks the same all the way through
- a mixture where you can see the different parts
- a solid that won't dissolve
- a single pure substance
a mixture that looks the same all the way through
Hint: In a solution, one substance dissolves evenly into another, so every part looks the same. Scientists call this homogeneous.
Question 10
Lever, wedge, or wheel and axle? Tap an item, then tap its basket.
Sort into: ⚖️ lever · 🔺 wedge · ⚙️ wheel and axle
- 🔪knife
- 🎡Ferris wheel
- 🔧crowbar
- 🎛️doorknob
- ⚖️seesaw
- 🚪doorstop
⚖️ lever: crowbar, seesaw · 🔺 wedge: knife, doorstop · ⚙️ wheel and axle: Ferris wheel, doorknob
Hint: A lever turns on a fulcrum. A wedge is thin at one edge to split, cut or hold. A wheel and axle is a wheel joined to a rod that turns with it.
Answer key
- 1. Mouth: teeth chew and saliva mixes in → Esophagus: muscles squeeze food down → Stomach: acid and juices churn the food → Small intestine: nutrients pass into the blood → Large intestine: water is absorbed (Digestion & Breathing)
- 2. The brain sends a signal to the biceps → The biceps contracts (gets shorter) → A tendon pulls on a forearm bone → The arm bends at the elbow joint (Heart, Bones & Muscles)
- 3. Run a magnet through the dry mix to pull out the iron → Add water and stir until the salt dissolves → Pour it through a filter to catch the sand → Let the water evaporate to leave the salt (Solutions & Mixtures)
- 4. 5 m ramp → 4 m ramp → 2 m ramp → 1 m ramp (Simple Machines)
- 5. Weathering breaks rock into small pieces → Erosion carries the pieces away → The sediment settles in layers → Layers are pressed and cemented into rock (The Rock Cycle)
- 6. Ancient plants and tiny sea creatures live and die → Their remains are buried under layers of sediment → Heat and pressure act on them for millions of years → They slowly become coal, oil or natural gas (Natural Resources)
- 7. the small intestine (Digestion & Breathing)
- 8. on the inside of your wrist (Heart, Bones & Muscles)
- 9. a mixture that looks the same all the way through (Solutions & Mixtures)
- 10. ⚖️ lever: crowbar, seesaw · 🔺 wedge: knife, doorstop · ⚙️ wheel and axle: Ferris wheel, doorknob (Simple Machines)
