Film movie cameras snap many photos per second. When the photos are shown in order at the same speed, they appear to move.

The First Cameras

Let’s take a trip back to the mid-1800s. At that time, there were no movies, TV shows, or tablets. A device called the camera had just been invented. Early photographers would coat a metal or glass plate with light-sensitive chemicals. They’d place the plate in a bulky camera box. When light entered the box, the chemicals reacted. Adding another chemical caused an image to appear.

People were amazed by the way cameras captured real life in pictures. But they soon wondered: Could cameras take pictures that moved?

The invention of film in the 1880s was an important step. Sold in rolls by a company called Eastman Kodak, film made it possible to take many pictures one after another.

Inventors set out to design cameras that could use film to make moving pictures. “The cameras had to move the film really fast, taking many photos a second,” says Vito Adriaensens. He’s an expert in film history. Showing the pictures one after the other could trick a viewer’s eyes. The still pictures would look like they were moving!

Cameras showed real life in pictures. People were amazed. But a question came up. Could cameras take moving pictures?

Film was invented in the 1880s. That was an important step. The Eastman Kodak company sold film in rolls. People could use it to take many pictures in a row.

Inventors wanted to make moving pictures with film. So they designed new cameras. “The cameras had to move the film really fast, taking many photos a second,” says Vito Adriaensens. He’s a film history expert. The pictures were shown one after the other. That tricked a person’s eyes. The still pictures seemed to move!

Designed in 1895, this camera could also project films. It made early moviemaking possible!

One of the first moving picture cameras, invented by the Edison Manufacturing  Company, was as big and heavy as a refrigerator! You could only watch the films on a one-person viewing device.

Later, French brothers Auguste and Louis Lumière invented a camera that was much lighter and more portable. It could also be used as a projector to show the moving pictures, or “movies,” to a crowd.

In 1895, the brothers used the device to show 10 of their films at a Paris café. It was one of the first public movie showings before an audience!

The first movie theaters opened in 1905. They were called nickelodeons because a ticket cost only a nickel.

From Silent to Sound

Thousands of movies were made with the Lumières’ camera. By connecting sections of film, people could tell longer stories—and create special effects, like making objects seem to vanish.

Today, these movies are called “silent films” because the cameras didn’t record sound. But in theaters, movie-watching was anything but silent! “There was live music, and people would narrate,” says Adriaensens. It was a noisy, interactive experience.

Filmmakers began making movies with sound in the 1920s. At first, they captured sounds on records and played them with the pictures. Shortly after, new technology allowed sound to be recorded on film.

Movies with sound, called talkies, were a huge hit! By about 1932, most U.S. theaters used projectors that played movies with sound.

People made thousands of movies with the Lumières’ camera. They connected pieces of film to tell longer stories. They also created special effects. For example, they made objects seem to vanish.

The cameras didn’t record sound. So we call these movies “silent films.” But movie-watching in theaters wasn’t silent! “There was live music, and people would narrate,” says Adriaensens. It was noisy and interactive.

The first movies with sound came in the 1920s. The sounds were on records at first. People played them with the pictures. New technology soon came along. Then sound was recorded on film.

Movies with sound were called talkies. They were a huge hit! So theaters got projectors that played them. Most U.S. theaters played movies with sound by about 1932.

Creating Color

Early talkies were filmed in black and white. In the 1930s, studios began using a new process to add color to film, called Technicolor. Cameras filmed through three colored filters. The films were combined to create bright, colorful images.

The Wizard of Oz, released in 1939, remains a famous example of Technicolor to this day. The bright green of the Emerald City and the deep red of Dorothy’s ruby slippers dazzled audiences.

But the technology was expensive. It was also uncomfortable! The lights needed to film in Technicolor heated up movie sets. The Wizard of Oz cast and crew sweltered in temperatures of 100° Fahrenheit (38° Celsius)!

In the 1950s, Kodak introduced color film. This made filming movies in color easier and less expensive.

Digital tools allow filmmakers to combine footage of actors with animation. In this scene from A Minecraft Movie, actors appear over an animated background.

The Future of Movies

By the late 20th century, movies had changed a lot. Filmmakers often worked with big teams of experts in filming, design, sound, editing, and more.

Plus, the next revolution in movie technology was underway—digital cameras. These devices record using sensors, not film. People edit the movies on computers. This has opened up new possibilities for special effects. Today some filmmakers are even using artificial intelligence to do things like add objects to scenes or make actors appear older or younger.

What’s next for movies? One thing’s for sure: They will continue to evolve. Next time you watch one, think of the inventors and artists who made it possible!

Step-by-Step Lesson Plan

1. PREPARE TO READ (5 minutes)
Activate prior knowledge about movies and how they’re made.

  • ASK: What are some of your favorite movies? In what year do you think the very first movies were made? How do you think those first movies might have been different from the ones you watch today? Have students jot down their responses. Then choose volunteers to share their ideas with the class.

2. READ AND Analyze (15 minutes)
Explain how movies have changed over time.

  • Play the video “Movies: Then and Now.” ASK: What surprised you the most about the history of movies? Have students turn and talk to discuss their responses.
  • Share the article and demonstrate how to preview it, skimming headlines and examining images along with their captions. Then read the article aloud, pausing to compare descriptions of early movies with students’ predictions. If time allows, have students practice their fluency by quietly rereading the article aloud with a partner.
  • Have students locate and compare the images of movie cameras from 1895 and from the 1990s. ASK: About how many years passed between the creation of these two cameras? (about 100 years) How are they similar? (e.g., They both have lenses.) How are they different? (e.g., One uses film to capture images, while the other uses sensors.)
  • Assess student comprehension with the Quick Quiz (available in higher- and lower-level versions).

3. RESPOND TO READING (25 minutes)
Make an image appear to move by creating a flipbook.

  • Examine the article’s images of the running horse. ASK: What changes between the frames? (e.g., the location of the horse’s legs) How did someone make these images? (They snapped a sequence of photos very quickly of a running horse.) What needs to happen for the images to appear to move? (They have to be quickly shown one after another.)
  • Preview the Make a Flipbook activity. If desired, play the “STEM in a Snap” video to guide students through the steps. Have students make and test their flipbooks. Afterward, allow students to walk around and try each other’s flipbooks. Reconvene and ask students to share what advice they would give someone who wanted to make their own flipbook.
