Using an example such as the distance from the Sun to the Earth (93 million miles) serves as a good example of scientific notation (9.3 x 10^7 -- the first number must be between 1.0 and 9.9) and how it differs from engineering notation (93 x 10^6 -- engineers group in thousands, millions and billions).
Familiarity with calculator notation which shows these numbers as 9.3E7 and 93E6 can help students understand and remember scientific notation. The video ends with a connection to children's literature with the delightful "Millions of Cats" by Wanda Gag.
