Soldering

Joining wire.

Today we learned about soldering. Daddy bought a soldering kit.

Soldering is where you heat up a special metal until it melts and then you use it to stick other bits of metal together. The special metal is called “solder”. It is mainly tin.

We started by watching a video on soldering.

Then we switched on the soldering iron, waited for it to get hot and melted some solder.

Hot, hot, hot.

We tapped the drops of solder onto some paper to have a look at them. They were shiny and all sorts of different shapes.

Next we tried soldering some wire together. It worked really well.

Daddy bought some bits of electronics so we could make something. There was an LED (a small light), a cable to connect a battery and a switch.

Frieda drew some of the things we were using.

We decided that we wanted to make a lamp for our dolls’ house. First we soldered the LED onto the battery cable. We put a straw over it to make part of the lamp. When we put batteries in the battery box the LED lit up!

We put some plasticine on one end of the straw and a paper cone on the other end. Then we added the switch. Here is the finished lamp in our dolls’ house:

Mummy wanted to know how to solder too so we showed her how it was done.

We liked soldering. We started to look around for things we could take apart and reuse. We found part of a solar lamp that we’re going to do something with next time.

We’re going to put all the bits we find into a special box.

    I loved hearing about this project! I am very impressed with the light for your dolls’ house – it’s lovely. When I was your age, I was only allowed to wind 1 end of a fuse wire around a torch bulb and the other to a battery to make it light up. I had to wait until I was 14 or 15 before I was allowed to solder things but I made wire sculptures using it rather than useful electronic things. I enjoyed soldering things, so am delighted to see you’re good at it!
