### 7 Lessons About Electricity - From the Archive

Due to an injury and some pressing personal matters requiring my attention, posts for the rest of week will be some favorites from the archives of the blog.

One of my most memorable elementary school science lessons included all of us creating working circuits with multiple switches to illuminate light bulbs. Our power source was 120 volt standard outlet. I don't think that would be allowed in most classrooms today, but our teacher, Mrs. Carlson, was young and fearless. I was reminded of that lesson this morning when I watched SciShow Kids' new video about the power of circuits. The video provides students with clear visuals and explanations of how a circuit works including the function of a switch. The video then demonstrates creating a circuit with a battery, small switch, and a light bulb.

Not all electricity is distributed in the same way. Some is distributed through direct currents like batteries in a flashlight and some is distributed through alternating currents which is what you find in the power lines running through your neighborhood. The following from Derek Owens explains the differences between direct current and alternating current.

An interesting TED-Ed lesson on The Science of Static Electricity.

Brain Stuff has a video that offers a good explanation of why we hear a buzzing sound coming from fluorescent lights found in many schools and office buildings. The video is embedded below.

Minute Physics offers a short video explaining how modern light bulbs work and how light bulb design has changed over the last 100+ years.The video also includes explanations of the different types of modern light bulbs and their applications. The video is embedded below.

Hydro to Home is an interactive story of hydro-electric power from raindrops to homes. The story walks visitors through each step of the process of generating hydro-electric power and delivering to consumers' homes. The story is narrated and along the way there are interactive images that visitors can click on to learn even more information about hydro-electric power.

The Blobz Guide to Electric Circuits is a neat series of interactive animations designed to help students of elementary and middle school age learn how electric circuits work. There are five sections to the series. Each sections builds upon the lessons of the previous section. The series starts with the basics of what makes a circuit complete and concludes with diagramming and building circuits. Each section in the series has a few short lessons and is followed by an animated interactive activity to which students can apply what they have just learned.

### Benefits of Using Backchannels In Your Classroom

Over the years I've introduced a lot of teachers to using  tools like Padlet, TodaysMeet, and Socrative in their classrooms. All three of these tools can be used as backchannel and informal assessment tools. I've written about various ways to use each of these tools in the past. (Click here for TodaysMeet, here for Padlet, and here for Socrative). Here are some of the key benefits of using backchannels in your classroom.

1. Shy students are given a place to ask questions and contribute to conversations.

2. Students who process information by asking a lot of questions can ask an unlimited amount of questions without dominating the classroom conversation. Everyone can see their questions and you can choose when to address their questions.

3. Gauge your students' interest in and or prior knowledge of a topic.

4. Extend your classroom conversations beyond the time in your school's schedule. If you have started a backchannel during a classroom conversation and it's going well you don't have to worry about running out of time because you can have students continue the dialogue later in the day. Students who thing of a question or comment later in the day can add them without having to wait until the next class meeting to share that question or comment.

5. Gauge the effectiveness of an activity in real time. By having students share questions and comments during an activity, you can get an immediate sense of the effectiveness of that activity by gathering feedback from all of your students.

### DOGO News - Current Events Lessons to Share in Google Classroom

DOGOnews is a student news site that features articles for K-8 students. DOGOnews covers current events stories in the areas of science, sports, entertainment, and variety of topics that fall under the banner of social studies. Teachers can find stories by browsing the categories, filtering by grade level, or filtering by grade level.

All articles on DOGOnews are accompanied by an embed code that you can use to put the story into a blog post for your students to read. There are two other ways to share articles and questions from DOGOnews. You can create an DOGOnews classroom account. In your classroom account you can post articles with notes and questions attached to them. When your students log into the classroom account they will see the articles you've posted along with the notes and questions you've added to the articles.

DOGOnews has a Google Classroom integration. The following video demonstrates the Google Classroom integration.

### How to quickly show or hide your Chrome bookmarks bar

In a webinar last week I incidentally showed a quick way to show or hide the bookmarks bar in Chrome. The webinar was not about Chrome or anything Google-related so I was surprised when someone asked me to show the trick again. There is not a trick, just hit CTRL+Shift+B to show  or hide the bookmarks bar. Watch my video below to see the tip in action.
