1. Display this icon:
Elicit any words related to it and its use. Write them down. Have the students complete the following sentence:
“Bluetooth is the technology that…”
The students share their sentences.
2. Ask the students to read about the origin of the name Bluetooth. Check comprehension orally.
3. For each sentence, the students look for extra information in the Bluetooth icon. Tell the students to pay attention to what or who the extra information is about so that they can match the sentences correctly and in the right place. Remind the students that, since this is additional information, they will be using non-defining relative clauses to rewrite the sentences (including the use of commas and not using “that” in this type of clause.)
1. Not many people have given much thought to the inspiration behind the iconic Bluetooth name and logo, which has become very popular.
2. Bluetooth is actually named after an ancient Viking king. King Harald, who reigned as the king of Denmark and Norway in the late 10th century, was known for uniting the tribes of Denmark and converting the Danes to Christianity.
3. Scholars say Harald was nicknamed “Blåtand”, which means blue tooth, because he had a dead tooth that looked blue and dark.
4. In December 1996, Intel’s Jim Kardach, who had read a book on Viking history, suggested the name Bluetooth as a codename until the marketing group could come up with a formal technology name.
5. “When I was asked about the name Bluetooth, I explained that Bluetooth was borrowed from the 10th century, second King of Denmark, King Harald, who was famous for uniting Scandinavia, just as we intended to unite the PC and cellular industries with a short-range wireless link,” Kardach said.
6. He added that he created a PowerPoint foil with a version of a runic stone, where Harald held a cellphone in one hand and a notebook in the other hand.
7. The codename Bluetooth was first used for a while. When other names, which had been considered for some time, did not work out, Bluetooth remained.
4. The students watch a short video with more information about the origin of Bluetooth. Have them read the selected words provided first and ask them to take notes about each of them as they listen, explaining why they are mentioned in the video.
