Tinkering with Circuits

They started with four piles – power sources, simple loads, switches, and complex loads – and by the time their hour of tinkering had passed, our students were expertly connecting multiple circuit elements together, drawing circuit diagrams, and investigating how to make more complicated circuit elements like 7 segment LEDs and potentiometers work.  And they were excited!

Persistence is a core part of what it means for students to become makers and circuit blocks is a persistence builder.  All of the students run into circuits they don’t quite know what to do with.  For some it is using a switch in a new situation without any guidance.  But most  struggled with how to use a potentiometer – you see this is the first time they have encountered an electrical device that has three connections.  And so they stumble through it generally using trial and error until they figure it out for themselves and then, hopefully, start to figure out how they can use this new device the next time they are confronted with it.Making9-13 130

But they do it themselves – and that is the magic.  They learn to persist, build, and they learn about electricity and how it works.  We all have to build our own understandings and giving students the chance to explore invests them in understanding these ideas at a deeper level than if they were just given a task to complete.

This activity was brought to us through a collaboration with the Exploratorium Tinkering Studio as part of their vision to bring activities they use on the floor of the museum to classrooms in schools.  Through this partnership we have been able to use circuit boards in 3rd, 7th, 9th, and 12th grades – and learn quite a bit about how different ages engage with and learn from an open ended hands-on activity.  They will continue to bring new activities to Lighthouse in the coming months – and we look forward to sharing them with you!

Kindergarten Starts with Sand

Making9-13 089Our plan for Kindergarten this year is to explore different media each quarter, giving them an opportunity to experience and experiment with a variety of materials.  The new group of five-year-olds entering school have been starting with sand and water.

We started with dry sand.  It didn’t take long to discover that it doesn’t stick together very well.  After pairing it with water they started to build and create. Some students focused their attention on free-form building; others packed containers with wet sand and dumped it out into a shape.  Others started experimenting with how to cut masses of sand.  Anyone who built sand castles as a child remembers the fun and frustration of trying to create a vision with such a temperamental medium.

As a final project for this unit, the students will be making sand sculptures with sand and glue, giving their structures a little more permanency.

One thing we quickly learned about sand and water is that you don’t want wet sand sitting around for long in the classroom — it gets pretty smelly!
