Once your students have completed at least five lessons of Programming 101 or equivalent coding experience, you can assign these NGSS-aligned projects to complement your teaching on topics in physics and chemistry. For example, if you’re teaching a lesson on Newton’s laws of motion, you can assign the Newton’s Third Law project. Your students will use coding and outside research to animate a scene that involves Newton’s third law, such as a collision, and show how Newton’s laws apply.

With this collection of physical science projects, you can easily integrate coding and project-based learning into your curriculum. Each STEM lesson walks students through how to make a project about something they’re learning in school with step-by-step instructions. At each step, it encourages them to make their project unique and interesting, emphasizing that coding is a creative medium much like writing or drawing.

We’re constantly updating our STEM courses with new projects, so if there’s something you’d like us to add, send us a message at

What Students Learn

  • Use programming for science projects
  • Build a slide show on a topic
  • Build a quiz game
  • Make an interactive charts and models
  • Use animation to illustrate
  • Narrate using your own voice
  • Use the physics engine to model
  • Troubleshoot and debug programs

Technical Requirements

* Online courses require a modern desktop computer, laptop computer, Chromebook, or Netbook with Internet access and a Chrome (29+), Firefox (30+), Safari (7+), or Edge (20+) browser. No downloads required.
* Tablet courses require an iPad (iOS 10+) with Tynker or Tynker Junior app installed and Internet access

Lesson Summary

Create a project that demonstrates your knowledge of density.
In this lesson, students will play a quiz game to learn which objects sink or float based on their density. They will need to drag the provided items to either the “sink” or “float” side of their screen, based on the item’s density. Next, students will follow a step-by-step tutorial in the DIY (do-it-yourself) module to create their own version of the quiz game they just played! Activities include changing the background; adding Actors; programming draggable Actors; programming objects to float or sink; and checking the user’s answers. If students finish early, ask them to show their project to a neighbor. How many objects did they answer correctly?

After completing the DIY module, students will be asked 5 multiple-choice quiz questions about density and whether or not a given item will float in water. By the end of the lesson, students will have experimented with coding concepts (e.g., simple costume handling, simple events, detecting conditions, conditional loops, simple motion, screen bounds, simple messaging, input/output) while creating an interactive quiz game where the user guesses whether a given item sinks or floats.

Code Blocks

  • Density: The amount of matter in a given space or volume, can be determined by dividing the mass of the object by its volume

Students will...
  • Inspect whether a specified object will sink or float
  • Use code blocks to create an interactive game where the player guesses whether a specified object will sink or float

  • Computers or iPads (1 per student) with student account access to

  • simple costume handling
  • simple events
  • detect conditions
  • conditional loops
  • simple motion
  • simple conditionals
  • advanced motion
  • screen bounds
  • simple messaging
  • input/output

  • NGSS-Science: 5-PS1-3

Class Presentations

These student-facing slide presentations help educators seamlessly run Tynker lessons in a virtual or physical classroom setting. Each lesson has its own set of slides that introduce the big ideas, suggest unplugged activities, and include a section for each activity module. While running lesson slides, you can switch back and forth between the activity, the slides, answer keys and other lesson materials.
