Down Clues

1. Part of a water bottle cap with screws
→ The threaded part or screw thread, but more commonly referred to as a screw.
→ But the clue says "part of a water bottle cap", so likely referring to the thread or threads. However, the answer might be SCREW since it's a type of simple machine.
Wait — let's reconsider: The cap itself uses a screw mechanism, so the answer could be SCREW.
✔ Answer: SCREW

2. Wheel and axle device that's often used with screws
→ A wrench or spanner? But the clue says “wheel and axle device” — perhaps a turning tool like a drill?
Actually, think of a hand drill or wrench — but better: DRILL? Or maybe SPANNER?
Wait — perhaps it's WRENCH. But let’s look at context.

Alternatively, consider Crank? No.

Another idea: BOLT? No.

Think again: What wheel and axle device is often used with screws?
→ A screwdriver has a handle (wheel) and shaft (axle), and is used with screws.
✔ Answer: SCREWDRIVER

But is that accurate? A screwdriver is not strictly a wheel and axle — it's more of a lever or wedge.
Wait — actually, some screwdrivers have handles that act as wheels, turning the axle (shaft). So yes, screwdriver can be considered a wheel and axle.

But let's check another possibility: DRILL? Yes, a hand drill is a wheel and axle.

But the clue says “device that’s often used with screws” — so screwdriver makes sense.

However, screwdriver may not be the best fit. Let’s try WRENCH?

Wait — a wrench is used with nuts and bolts, not necessarily screws.

Best fit: SCREWDRIVER.

✔ Answer: SCREWDRIVER

3. Type of simple machine that is a flat surface with one end higher than the other
→ That’s an inclined plane.
✔ Answer: INCLINED PLANE

4. When you push, pull, or turn something you are applying this
→ Force
✔ Answer: FORCE

5. Pulleys are used to raise a flag on this tall object
→ A flagpole
✔ Answer: FLAGPOLE

6. Now that kids do on, often found on a playground
→ Kids play on a slide or swing? But “now that kids do on” — awkward phrasing.

Likely means: “Something kids use on a playground” — possibly swing?

But earlier we had “slide” for Across 7.

Wait — Down 6: “Now that kids do on, often found on a playground”

This seems poorly worded. Maybe it's meant to be “something kids ride on”?

Possibly SEESAW? That's a lever.

Or SWING?

But “do on” — maybe it's PLAYGROUND?

No — too long.

Wait — perhaps it's SEE-SAW? But only 6 letters.

Let's look at the grid:

- Down 6: 6 letters
- Across 10: GARDEN (6 letters)
- Down 6 intersects with Across 10 at letter 6 — so if Across 10 is GARDEN, then Down 6 starts with G.

So Down 6 must start with G.

So what is a 6-letter word starting with G, often found on a playground, that kids use?

→ GARAGE? No.

→ GO-KART? Not really.

→ GLIDER? No.

→ GYMNASIUM? Too long.

Wait — maybe it's GROUND? But that's not a thing kids do on.

Hmm.

Perhaps it's GRAVITY? But that’s not something kids do on.

Wait — maybe the clue is misphrased.

Alternative interpretation: “Now that kids do on” — perhaps “a place where kids play”?

But still.

Wait — maybe it's SWING? But S starts with S.

Unless it's Glider? No.

Wait — could it be GOLF? No.

Perhaps it's GRASS? But not a playground item.

Another idea: Could it be GARDEN? But that's Across 10.

Wait — Down 6: 6 letters, starts with G.

Possible words: GARDEN? But already used.

Wait — maybe the clue is: “Now that kids do on, often found on a playground” — perhaps it's SEE-SAW? But starts with S.

Or SLIDE? Starts with S.

Hmm.

Let's skip and come back.

Wait — maybe it's JUMP? But not 6 letters.

How about RAMP? But R.

Wait — could it be TUNNEL? T.

Nothing starting with G.

Wait — maybe it's GROUNDS? But not a playground object.

Wait — perhaps the clue is: “Now that kids do on” — maybe it's a typo?

Alternatively, could it be GIGGLE? No.

Wait — perhaps it's GAME? Too short.

Another thought: Is it possible that the clue is meant to say “A place where kids play”?

Then “playground” — but 10 letters.

Wait — Down 6: 6 letters, starts with G.

Let's look at the crossword grid.

We know:

- Across 1: SCISSORS (8 letters)
- Across 2: DOORKNOB (8 letters)
- Across 3: KNIFE (5 letters)
- Across 4: FULCRUM (7 letters)
- Across 5: SIX (3 letters)
- Across 6: PULLEY (6 letters)
- Across 7: SLIDE (5 letters)
- Across 8: WHEEL AND AXLE (13 letters — but written as one word? Probably hyphenated)

Wait — Across 8: “Type of simple machine that's made of a wheel attached to a rod” → WHEEL AND AXLE — but that’s 13 characters, including spaces.

In crossword puzzles, compound words are sometimes written without spaces or with hyphens.

But let's assume it's WHEELANDAXLE — no, unlikely.

More likely: WHEEL AND AXLE — but in the grid, it must fit.

Looking at the grid layout:

- Across 8 spans from column 1 to 13 — 13 squares.

So likely: WHEEL AND AXLE — but written as 13 letters: W H E E L _ A N D _ A X L E

But that’s 13 letters with spaces — no, crosswords don’t have spaces.

So probably: WHEELANDAXLE — but that’s not standard.

Wait — maybe it's WHEEL AND AXLE — but split across multiple entries?

No — it's one entry.

Alternatively, the answer might be WHEELAXLE — but not common.

Wait — perhaps it's AXLE? No.

Another possibility: WHEEL? But that’s not complete.

Wait — maybe it's WINDMILL? No.

Actually, the correct term is wheel and axle, and it's often accepted in crosswords as WHEEL AND AXLE — but in a grid, it would be written as 13 letters with spaces or hyphenated.

But in this puzzle, the grid shows 13 boxes for Across 8.

So likely, the answer is WHEEL AND AXLE, but in the puzzle, it might be written as WHEELANDAXLE or WHEEL-AXLE.

But let's assume it's WHEEL AND AXLE.

Now, Down 6: 6 letters, starts with G.

Let’s look at the intersections.

Across 10: GARDEN (6 letters) — starts at row 10, column 1.

So Down 6 goes down from row 1 to row 6 — 6 letters.

So Down 6: 6 letters, starts with G.

And intersects with Across 10 at row 10, column 1 — but Across 10 is row 10, column 1 to 6.

Down 6 is column 1, rows 1 to 6.

So Down 6: 6 letters, first letter G.

Across 10: GARDEN — so G is at (10,1), which is the last letter of Down 6.

So Down 6 ends with G?

Wait — no!

If Down 6 is from row 1 to row 6, column 1, then:

- Row 1, col 1: first letter of Down 6
- Row 6, col 1: sixth letter of Down 6
- Across 10 is row 10, col 1 to 6: GARDEN

So they don’t intersect.

Wait — perhaps the grid numbering is off.

Let me reconstruct the grid.

From the image description, the puzzle has:

- Across clues numbered 1 to 10
- Down clues numbered 1 to 10

Looking at typical layouts:

- Across 1: 8 letters — SCISSORS
- Across 2: 8 letters — DOORKNOB
- Across 3: 5 letters — KNIFE
- Across 4: 7 letters — FULCRUM
- Across 5: 3 letters — SIX
- Across 6: 6 letters — PULLEY
- Across 7: 5 letters — SLIDE
- Across 8: 13 letters — WHEEL AND AXLE (but how?)

Wait — perhaps it's WHEEL AND AXLE — but in crossword form, it might be written as WHEELANDAXLE — 13 letters.

But that’s unusual.

Alternatively, maybe it's WHEEL — but that’s not enough.

Wait — another possibility: WINDMILL? No.

Wait — perhaps the clue is “Type of simple machine that's made of a wheel attached to a rod” — that’s wheel and axle.

So the answer is WHEEL AND AXLE — but in the puzzle, it might be abbreviated or written as WHEELAXLE.

But let's accept it as WHEEL AND AXLE — 13 letters.

Now, Down 6: 6 letters, starts with G.

Let’s look at Down 6 clue: “Now that kids do on, often found on a playground”

Still unclear.

Wait — perhaps it’s SWING? But S.

Another idea: SEESAW — 6 letters, starts with S.

But we need G.

Wait — could it be GIRAFFE? No.

GARDEN — but that’s Across 10.

Wait — perhaps the clue is “Now that kids do on” — maybe it’s a typo for “a place where kids play” — then “PLAYGROUND”, but too long.

Alternatively, could it be GAME? Too short.

Wait — perhaps it’s GLOVE? No.

Another possibility: GOAL? No.

Wait — maybe it’s GOGGLE? No.

Let’s try a different approach.

Look at Down 1: “Part of a water bottle cap with screws” — likely THREADS or SCREW.

But “part” — so maybe THREAD?

But “with screws” — so perhaps SCREW.

But “part of” — so THREAD?

Let’s say SCREW.

Down 2: “Wheel and axle device that's often used with screws” — SCREWDRIVER — 11 letters.

But Down 2: how many letters?

From grid: Down 2 starts at row 1, column 2 — goes down.

How many rows? Let’s estimate.

But without the visual, hard.

Wait — perhaps we can infer.

Let’s list all answers we have:

### Final Answers (after research and logic):

Let’s fill in known ones:

- Across 1: SCISSORS
- Across 2: DOORKNOB
- Across 3: KNIFE
- Across 4: FULCRUM
- Across 5: SIX
- Across 6: PULLEY
- Across 7: SLIDE
- Across 8: WHEEL AND AXLE (written as 13 letters)
- Across 9: SAIL
- Across 10: GARDEN

Down:

- Down 1: SCREW (part of bottle cap — the threads are screws)
- Down 2: SCREWDRIVER (used with screws)
- Down 3: INCLINED PLANE
- Down 4: FORCE
- Down 5: FLAGPOLE
- Down 6: ??? (starts with G, 6 letters, playground item)

Wait — Down 6: 6 letters, starts with G.

What 6-letter word starting with G is on a playground?

- GARDEN — but that’s Across 10.
- GROUND — not a specific item.
- GLOVE — no.
- GAMBLE — no.

Wait — perhaps it's SEESAW — but S.

Another idea: GIRDLE? No.

Wait — could it be GRASS? But not a structure.

Perhaps the clue is misread.

Let’s re-read: “Now that kids do on, often found on a playground”

Maybe it's “a place where kids play” — but then “playground” — 10 letters.

Or “slide” — but S.

Wait — perhaps it's SWING — but S.

Unless it's GOLFER? No.

Wait — could it be GATE? No.

Another possibility: GRADE? No.

Wait — perhaps it's GEAR? No.

Let’s consider that the clue might be: “Now that kids do on” — perhaps “a ramp” or “a slide”?

But both start with S.

Wait — maybe it's GROW? No.

Perhaps the answer is GARDEN — but that's Across 10.

Wait — Down 6 might be GARDEN — but only if it's vertical.

But Across 10 is GARDEN, horizontal.

So Down 6 cannot be GARDEN.

Unless the grid has GARDEN going down — but clue says “area used for digging” — so garden is correct for Across 10.

So Down 6 must be something else.

Let’s try to find a 6-letter word starting with G that is a playground equipment.

- SEE-SAW — 7 letters.
- SWING — 5.
- SLIDE — 5.
- TUNNEL — 6, but T.
- CASTLE — 6, but C.
- MOUSE — no.

Wait — GHOST? No.

Perhaps it's GOGGLE? No.

Another idea: GOLDEN? No.

Wait — could it be GIRTH? No.

Perhaps the clue is: “Now that kids do on” — meaning “a game kids play” — then TAG? Too short.

Or HOPSCOTCH? Too long.

Wait — perhaps it's JUMP? No.

Let’s skip and look at Down 7.

Down 7: “Type of simple machine made up of a bar that moves on a fixed point, or fulcrum” — that’s a lever.

✔ Answer: LEVER

Down 8: “Type of simple machine that's spiral-shaped and pulls two things together” — that’s a screw.

✔ Answer: SCREW

Down 9: “A simple machine used to separate something; made up of two inclined planes back-to-back” — that’s a wedge.

✔ Answer: WEDGE

Down 10: “Simple used for changing speed” — wait, “simple” likely means “simple machine”.

“Used for changing speed” — that’s a gear or wheel and axle.

But “changing speed” — gears are used for that.

So GEAR.

✔ Answer: GEAR

Now, Down 6: 6 letters, starts with G.

Let’s see what fits.

Down 6 clue: “Now that kids do on, often found on a playground”

With Down 7 being LEVER (4 letters), and Down 6 above it.

If Down 6 is 6 letters, and Down 7 is 4 letters, they might be adjacent.

But we don't know positions.

Wait — perhaps Down 6 is GARDEN — but only if it's vertical.

But Across 10 is GARDEN.

So unless the grid has GARDEN vertically, it can't be.

But the clue for Across 10 is “area used for digging/hoes in the ground” — so GARDEN is correct.

So Down 6 must be something else.

Wait — perhaps the clue is: “Now that kids do on” — maybe it's “a swing set” or “a seesaw”?

But no G.

Another possibility: GOLFER? No.

Wait — could it be GROOVE? No.

Perhaps it's GIMBAL? No.

Wait — maybe it's GALLERY? No.

Let’s consider that the clue might be: “Now that kids do on” — perhaps it's a typo for “a place where kids play” — then “PLAYGROUND”, but too long.

Or “PLAY AREA”? No.

Another idea: GROUND — 6 letters, starts with G.

And “kids play on the ground” — but not a specific object.

But “often found on a playground” — yes.

And “now that kids do on” — perhaps “kids play on the ground”.

So maybe GROUND.

✔ Answer: GROUND

Let’s test:

- Down 6: GROUND — 6 letters, starts with G.
- Intersects with Across 10? Across 10 is GARDEN — so at (10,1): G — matches.

But Down 6 goes from row 1 to row 6, column 1.

Across 10 is row 10, column 1 to 6.

So no intersection.

But if Down 6 is GROUND, and it’s in column 1, rows 1-6, then:

- Row 1, col 1: G
- Row 2, col 1: R
- etc.

Across 10 is row 10, col 1: G — so if Down 6 ends at row 6, and Across 10 starts at row 10, no overlap.

So no issue.

So Down 6: GROUND

But is it “often found on a playground”? Yes, grassy ground.

And “kids do on” — play on it.

So plausible.

Alternatively, GRASS — but 5 letters.

So GROUND is acceptable.

Now, Down 1: “Part of a water bottle cap with screws” — the threaded part — THREADS or SCREW.

But “part” — so THREAD?

But “with screws” — so likely SCREW.

✔ Answer: SCREW

Down 2: “Wheel and axle device that's often used with screws” — SCREWDRIVER

But how many letters?

SCREWDRIVER = 11 letters.

Down 2: likely 11 letters.

So possible.

Down 3: INCLINED PLANE — 13 letters.

Down 4: FORCE — 5 letters.

Down 5: FLAGPOLE — 8 letters.

Down 6: GROUND — 6 letters.

Down 7: LEVER — 5 letters.

Down 8: SCREW — 5 letters.

Down 9: WEDGE — 5 letters.

Down 10: GEAR — 4 letters.

Now, let’s compile the final answers.

Explanation of Key Terms

- Scissors: A compound machine combining two levers.
- Doorknob: A wheel and axle that turns to open a door.
- Knife: A wedge used for cutting.
- Fulcrum: The pivot point of a lever.
- Six simple machines: Lever, wheel and axle, pulley, inclined plane, wedge, screw.
- Pulley: A wheel with a groove for a rope, used to lift objects.
- Slide: An inclined plane on a playground.
- Wheel and axle: A wheel attached to a rod (axle), like a doorknob or steering wheel.
