Question 1
Put the life cycle of a bean plant in order. Tap the first stage first.
- 🫘pods with new seeds
- 🌼plant with flowers
- 🌿seedling with leaves
- 🌰seed
- 🌱seed sprouts
seed → seed sprouts → seedling with leaves → plant with flowers → pods with new seeds
Hint: A seed sprouts into a seedling, grows leaves, flowers, and makes new seeds.
Question 2
Why do we put sand on an icy sidewalk?
🧂- to add friction so people don't slip
- to make the ice melt in a second
- to make it slipperier
- to make it brighter
to add friction so people don't slip
Hint: Sand makes the surface rough, so shoes can grip.
Question 3
Which is the right order for a plant?
- seed, seedling, adult plant, seeds
- seedling, seed, adult plant
- adult plant, seed, seedling
seed, seedling, adult plant, seeds
Hint: A plant grows from seed to adult and makes more seeds.
Question 4
Speed is found by thinking about distance and…
- price
- color
- time
time
Hint: Speed describes distance over time.
Question 5
A sprout grows pale and tall in the dark. Its color is affected by…
- its parents
- its seed shape
- lack of light
- its age only
lack of light
Hint: Plants need light to be green.
Question 6
Musk oxen form a circle around their young. Why?
- To keep cool
- To protect them
- To play a game
- To find food
To protect them
Hint: Adults guard the calves.
Question 7
Which material is best for a roof in a hailstorm?
- Paper
- Strong metal
- Thin plastic wrap
- Cloth
Strong metal
Hint: Hail is hard ice.
Question 8
A magnet's pull gets weaker when it is…
- colder
- farther away
- closer
- painted
farther away
Hint: Distance matters.
Question 9
How does the seed travel? Tap an item, then tap its basket.
Sort into: 🌬️ carried by the wind · 🐿️ carried by animals
- 🐿️acorn buried by a squirrel
- 🐦berry eaten by a bird
- 🍁maple key (a seed with a wing)
- 🌼dandelion fluff
- 🌿milkweed fluff
- 🐕burdock burr stuck in fur
🌬️ carried by the wind: maple key (a seed with a wing), dandelion fluff, milkweed fluff · 🐿️ carried by animals: acorn buried by a squirrel, berry eaten by a bird, burdock burr stuck in fur
Hint: Light fluffy or winged seeds ride the wind. Sticky burrs and tasty fruits travel with animals.
Question 10
Does the force need touching? Tap an item, then tap its basket.
Sort into: 🤝 contact force · 🧲 non-contact force
- 🍎an apple falling from a tree (gravity)
- 🚪pushing a door open
- 🧲a magnet pulling a paper clip
- 🎈a balloon sticking to a wall (static)
- ⚽kicking a ball
- 🤲rubbing your hands together (friction)
🤝 contact force: pushing a door open, kicking a ball, rubbing your hands together (friction) · 🧲 non-contact force: an apple falling from a tree (gravity), a magnet pulling a paper clip, a balloon sticking to a wall (static)
Hint: A contact force happens when things touch. Gravity, magnetism and static electricity can act from a distance.
