The perfect project, I think, is one that combines creativity and learning. This STEM activity fits the bill. Middle daughter really wanted to make an articulated hand. I’ve seen the project before, but was impressed by how clear the instructions were in the Amazing! magazine. Middle is now of the age that she can follow the instructions by herself, with very little
interference help from me.
We used my glue gun to stick the straws to the cardboard. The only other change she made was using cardboard from a cereal box instead of corrugated cardboard. The end result is remarkably sturdy, and strong enough for everyone in the family to play with.
She raided my dressmaking tools and found my loop turner, which is used to turn spaghetti shoulder straps the right way round. Having a latch hook at the end, it was perfect for pulling the wool through the straws.
We used the glue gun again to stick the rubber bands to the back of hand, so the hand will return to a flat state.
We recorded a video to show you how good the movement turned out. I’ve sped it up. It only takes 12 seconds.

Last year, I bought a Glowing House Set for my Middle daughter. I wanted something that coupled her curiosity in science and her artistic nature. It was both a craft and engineering project.
Over the Christmas holiday, she sat down and made the houses. Putting the houses together, decorating them and creating the electronic circuit. All by herself.
The electronics in the roof are the clever part of the kit. She used electric paint, (the black lines in the photo above) to make the circuit which linked the LEDs to the battery and the light sensor. It’s called cold soldering. A great way for a child to make a circuit without risking burnt fingers.
It worked. The houses lit up when the light sensor was triggered in the evening. Very cool for an eleven year old. Only slight problem was that the blue LED was not lighting up. The rest were working. By then the electric paint was dry and would become brittle if broken. Not great for problem solving, as it would destroy the working part of the circuit, so she carefully removed the blue LED.
She took the problem to her father and he had a solution. (Aren’t Dads great?) He found a breadboard (the white board above, not for slicing loaves) to test the blue LED. It didn’t take long for all the children to join in. Pushing in the jumpers, resistors, transistors and lights. Making LEDs light up and the noise component to vibrate noisily.

They made mistakes. Some components died. I cannot lie, but they had even more successes and they learnt so much. Oh, those curious minds. The hands on experience, of putting the circuits together, was perfect. They were captivated.
Oh, and what of the blue LED?
The original problem?
It was dead. It happens. Do you know what, I’m glad it didn’t work? I would not have thought of buying her a breadboard to experiment with. If all the components had worked in the original kit, she would never have experienced the process of isolating the fault.
She loves both kits and has learnt so much. More importantly, she wants to do more.
Steps on to soap box: This is NOT a sponsored post, in any shape or form. I am fortunate to have an engineering father who saw no reason why his youngest daughter shouldn’t become an engineer too, and provided encouragement. That was me, and I did. I’d like my children to see no barriers to pursuing careers in science or engineering, if they want to, especially my daughters. This kit is perfect for stretching her experience. I also love that it does not patronize her or seem to overtly attract her by being obviously for a “girl”. No stereotypes.
