Science Heroes: Digestive System for Kids

Common Sense Media says

Animations and games engage; learning approach needs boost.






What parents need to know

Ease of play

The start-up images that kids have to tap are a bit confusing and do not include any narration or text. Once kids get to the the main page, navigation is easy. Game controls may be difficult for some users to master. 

Violence & scariness

There is mild cartoon violence. The primary goal of the missions is to break down food particles or destroy harmful substances. Kids spend a lot of time shooting at these objects.

Parents Need to Know

Parents need to know that Science Heroes: Digestive System for Kids aims to teach young learners about the digestive system, offering options in English or Spanish. A video reviews key concepts and vocabulary, and it includes colorful animations that will engage kids. Leveled games challenge kids to protect different parts of the digestive system by completing missions such as chomping food particles and blasting harmful substances. However, the focus on learning gets somewhat lost. Brief quizzes are given between game levels, but kids are likely to spend more time trying to blast the enemy than learning about the digestive system. Users can try a free version of the app, which includes one game level. The full, paid version includes five levels.

Engagement, Approach, Support


Kids will enjoy watching the video animations and playing the games. The challenge of unlocking levels is a great motivator.

Learning Approach

Learning content is thin; a video is the primary source of content, with two-question quizzes given between game levels. Kids likely will focus more on shooting objects than on learning about the digestive system.


Users can request a learning guide in the parents' section. Audio and text are available in English and Spanish, and kids get instant feedback in the quizzes.

What kids can learn



  • biology


Thinking & Reasoning

  • memorization

Kids can learn key concepts about the human digestive system through a video filled with lots of information and engaging visuals. After kids complete a game level, they have to answer two quiz questions. This helps reinforce learning, and kids get instant feedback. But, depending on how long it takes kids to complete a level, a lot of time may pass between viewing the video and answering the questions. Gaming skills are a heavy focus with Science Heroes: Digestive System for Kids; it could work as a way to get kids interested in the digestive system, but it doesn't offer deep learning.

What's it about?

On the main page of SCIENCE HEROES: DIGESTIVE SYSTEM FOR KIDS, users have three options: Tap the gear icon to control the sound and choose a language (English or Spanish), tap the Parents section to sign up for a learning guide and read the privacy policy, or tap the green arrow to start playing the game. Upon tapping the green arrow, first-time users are taken to an instructional video that lasts just over three minutes; an Internet connection is required to watch the video. Next, kids are given a series of missions, three per game level, that are broken down by body part: mouth, esophagus, stomach, small intestine, and large intestine. Each mission begins with an explanation, and the general theme is to shoot at various objects such as food particles (to break them down) or harmful substances (to protect various body parts). Kids have to complete each mission set and answer two quiz questions to unlock the next level.

Is it any good?


Kids will enjoy the video and the challenging missions in Science Heroes: Digestive System for Kids. The colorful characters and animations are engaging, and the science content is presented at an age-appropriate level. Quizzes between game levels attempt to reinforce learning, but they are so staggered that kids may have a hard time recalling the information. On a positive note, feedback for incorrect answers is provided, so kids can learn from their mistakes.

Although the graphics are well done and the missions are fun and engaging, kids are probably not going to spend most of their time learning about the digestive system. Instead, they likely will focus on shooting at targets in hopes of advancing to the next level. 

Families can talk about...

  • Search for diagrams of the digestive system and talk with kids about the processes that occur in each structure.


  • While watching the video, pause it as needed so kids can jot down key terminology. Then have them create an illustrated glossary.
