1st Grade Update: From Light Bulbs to Motion Pictures

Since our opening unit on learning styles and multiple intelligences, we've covered LOTS of ground researching Edison and related inventions. 

We started with some traditional research using the text Thomas Edison and the Light Bulb and gathered our data into a class "big book."

One of our major research questions was to discover what material made the best filament inside the light bulb for it to last the longest. Originally, light bulbs used cotton thread for the filament. You can imagine the problem with that. After experimenting with THOUSANDS of different options, the best material Edison found for a long-lasting bulb was bamboo! Today, tungsten is the most favored material for a filament in a traditional light bulb.

We balanced out the analytical thinking required for our research with a creative challenge: design a light bulb of the future using LEGO pieces!

Next, we applied our growing knowledge of light bulbs by using the classic picture book The Important Book as a model to create our own "important pages" about the light bulb. We also illustrated and diagrammed the major parts of the light bulb to go along with it.

Then it was time to move beyond the light bulb and look at another project that Edison played a role in: the motion picture (AKA the movies!). We discussed the concept of persistence of vision that early animators used to explain how a series of still images could seem to move. Edison was fascinated during his life with one particular, very simple animation device called a thaumatrope. Here's a video with the instructions we used to make our own. The students learned by trial and error which methods worked best and created some very fun, animated scenes! 

Our next step is to take a technological leap but use the same basic methods to create a more complex movie. We'll be using a stop-motion movie maker app on the ipads. Our next update should be some movies for you to watch!
