Astonishing inventions that made the IT revolution possible
Hello Everyone! It is so nice to have time to put some finishing touches on a couple of units that we have coming up! Another historical figure we will study after Eleanor Roosevelt is Dr. Martin Luther King, Jr. As a nation we celebrate his life daily! Thank you Dr. King! Officially we celebrate on the third Monday of January. I have posted about our activities before, but I went through and cleaned up, and added to my unit. Here are some pics from the updated unit! If you would like the 30 page free printable unit CLICK HERE!! :) My second offering for today is a unit our curriculum team worked on this summer. We had fun integrating reading and social studies and are finding it a natural way to teach and get everything in. This next unit is about other important historical figures. It includes posters about Alexander Graham Bell, Ben Franklin, Thomas Edison, Garrett Morgan, and Richard Allen along with reading strategy practice activities. It also includes an invention home project packet for kids. The unit ended up to be over 50 pages! I am excited to include this unit in our curriculum in a few weeks!! Here are a few pics from the unit! For your free 52 page Inventors Unit CLICK HERE!! :) So glad I had time to share these endeavors! Hope you can use at least parts of either one! It is my joy to be able to share and help your journey in the classroom or homefront become a little less stressful. As always, please let me know if this is something you can use, if there are any typos or problems, and if you would like to see something else in particular on this little blog. I hear from teachers and parents from all over the world, and I am so grateful for all of you!! Joyfully! Nancy
By designating the realm of technology as 'male,' we overlook key inventions that took place in the domestic sphere
We are now living through a post-Gutenberg moment. The advent of the world wide web has made it possible for individuals to publish and distribute their ideas at a cost that is quickly moving toward zero. So what does this mean for schools today?
Students have to watch the video at https://www.youtube.com/watch?v=F0Ypz9TDMTE and complete exercise A with the necessary information. Some words already have the first letter. Then they answer some questions about themselves. Finally they will have to identify the free time activities shown in the different pictures. Hope you like it. - ESL worksheets

Jacquard’s invention revolutionized the textile industry in the early 1800s. Learn about him, the fabric, and how the Jacquard Loom led to computer technology and the device you are reading this on.
Aspen Aerogels, which makes what arguably is the world’s best insulation, has flopped in a hot market. The company, which produces a super insulating material that leverages the unique properties of air, offered 7.5 million shares for $11 per share this week, below the anticipated $14 to $16 per share price.

Hollerith is a name that you'll come across if you study computer science. Several concepts have been named after Herman Hollerith who invented an automated punch card tabulating machine. Herman Hollerith was one of the founders of a company that later became IBM. Hollerith's invention lead to the punched cards which were a big part of the day to day work of early professional computer programmers. Herman Hollerith was born on February 29th 1860 in Buffalo, New York. Yes, he had a leap day birthday, so we thought we'd better cover him today or we would have to wait another 4 years! We think it's important that kids understand the history of computing. Most western kids today grow up with internet at home and access to mobile technology. We've previously written about key tech innovators such as Ada Lovelace, George Boole, Grace Hopper and Thomas Edison. Hollerith originally invented his punch card machine for accurate data handling for the US census. (There had been punched cards before in use in weaving looms and musical instruments.) IBM progressed the use of punch card based machines and early general purpose computers were programmed with punch cards. Thanks to Hollerith, early computer programmers were able to capture their programs on physical punched cards that could be fed into a computer. This meant that programs could be prepared in advance and modified by adding, removing or physically editting cards. Punch Card Early computer programmers didn't have the benefit of being able to run their code immediately. They would have to write the whole thing and then submit it when they got a slot on a computer. It was very annoying if it had a bug. Throughout my career I met lots of people who had used punched cards in their job. The legacy of punched cards was very strong in the layout of the FORTRAN programming language that I used in one of my early jobs. If you want to see a punch card preparation machine then watch Bubble Whiting's fantastic demonstration and explanation of how she used one in her job: In this video Professor Brailsford explains how punch cards, or Hollerith cards, work and shares his experience of using them: In these days of fantastic browser based coding sites for kids, Hollerith cards look really hard work! But they were a significant step towards coding becoming accessible.
