Step-by-step guide to safely take apart a battery-powered toy

What you need

Old battery-powered toy, small screwdriver set, tray or bowl, soft towel or cloth, safety goggles, paper, pencil, flashlight or magnifying glass, colouring materials, adult supervision required

Step 1

Gather all your materials and bring them to a clean table.

Step 2

Take out the batteries from the toy and put them aside in a safe spot.

Step 3

Put on your safety goggles so your eyes are protected.

Step 4

Lay the towel on the table and place the tray on the towel to catch tiny parts.

Step 5

Ask an adult to help you open the toy using the correct screwdriver.

Step 6

Carefully separate the toy halves so you can see the inside parts.

Step 7

Put all screws and small loose parts into the tray so nothing gets lost.

Step 8

Use the flashlight or magnifying glass to look closely at the motor gears and circuit board.

Step 9

Draw the inside layout on your paper showing where each part sits.

Step 10

Label the motor gears and circuit parts on your drawing using colouring materials.

Step 11

Tell your adult how you think the batteries make the motor turn the gears and move the toy.

Step 12

Ask your adult to help you reassemble the toy following your drawing as a guide.

Step 13

Put the batteries back in and turn the toy on to see if it works again.

Step 14

Share your finished creation and what you learned on DIY.org.

What can I use if I don't have safety goggles, a tray, or a magnifying glass?

If you don't have safety goggles or a magnifying glass, wear adult safety glasses or make a cardboard eye shield for the step "Put on your safety goggles" and use a shallow baking tray or muffin tin instead of the tray to hold screws during "Put all screws and small loose parts into the tray".

My toy won't work after reassembly—what should I check?

If the toy doesn't work after "Put the batteries back in and turn the toy on", reopen it with an adult and use your drawing from "Draw the inside layout" to confirm the motor gears and circuit board are seated correctly, battery contacts are clean and batteries are inserted the right way, and no wires were pinched when you "Carefully separate the toy halves".

How can I adapt this activity for different ages?

For ages 3–6 have an adult remove screws and let the child do steps like "Use the flashlight or magnifying glass" and "Draw the inside layout" with crayons, for 7–10 let them help with the screwdriver under supervision and label parts in "Label the motor gears and circuit parts", and for 11+ encourage independent disassembly, circuit inspection, and explaining in step "Tell your adult how you think the batteries make the motor turn the gears".

How can we extend or personalize the activity once it's done?

Turn your labeled drawing into a repair guide, decorate or repaint the toy shell after reassembly, test different battery types to compare runtime in "Put the batteries back in and turn the toy on", or design and 3D-print a replacement gear if you found a damaged motor gear during inspection.

Facts about basic electronics and mechanics

🧸 Archaeologists have found toys from ancient civilizations — some are over 4,000 years old!

⚙️ Gears go way back: the Antikythera mechanism (around 100 BCE) used complex gears to track astronomy.

🔋 Many toys use disposable alkaline batteries, but rechargeable NiMH batteries can often be reused hundreds of times.

🔌 Small DC motors in battery-powered toys usually run on low voltages (often 1.5–9 V) to turn electricity into motion.

🔍 Safety first: always remove batteries and have an adult help when taking a toy apart — batteries can leak and small parts are choking hazards.

How do I do the Toy's Anatomy activity—taking apart a battery-powered toy safely and reassembling it?

To do Toy’s Anatomy, pick an old battery-powered toy that’s broken or unwanted and remove the batteries. Work on a clear, well-lit surface and wear safety goggles. With an adult, carefully unscrew the case, photographing each step. Place screws and small parts in labeled containers and identify gears, the motor, and the circuit board. Sketch or explain how parts connect, then reassemble and test with fresh batteries only after checking connections and safety.

What materials and tools do I need for Toy's Anatomy disassembly?

Materials: an old battery-powered toy (dead or unwanted), small Phillips and flathead screwdrivers, safety goggles, and work gloves. Use a shallow container or ice-cube tray for screws, a smartphone or camera to document steps, magnifying glass, tweezers, notebook and marker for labels. Optional: multimeter, small pliers, and insulating tape. Avoid attempting soldering or live repairs unless a trained adult handles them.

What ages is the Toy's Anatomy activity suitable for?

Toy’s Anatomy is best for children aged about 7 and up with close adult supervision. Younger kids (4–6) can observe, sort and draw parts while adults do the tool work. Ages 7–10 can help unscrew, identify parts, and label components with guidance. Ages 11–15 can take a bigger role in examining circuits and using basic tools, but an adult should manage batteries, sharp tools, and any electrical testing.

What are the benefits, safety tips, or variations for Toy's Anatomy?

Benefits: builds mechanical and electrical understanding, vocabulary, fine motor skills, and problem-solving while promoting reuse. Safety tips: always remove batteries, discard swollen cells safely, wear goggles, keep tiny parts away from toddlers, and have an adult handle sharp tools, soldering, or live testing. Variations: compare two toys’ gear ratios, repurpose parts for art or simple inventions, or focus on only motors or only circuit boards for a shorter session.
