Objectives

In this activity, students will:

  • Learn how to use an Augmented Reality (AR) program to explore how AR works.
  • Practice creating objects using AR by visualizing them in 3D.
  • Engage in interactive learning to evaluate how AR might enhance learning science topics.

Research

  • Discuss with your students the importance of becoming a creator of technology rather than just a consumer of technology. Technology is not just smart phones and computers, but any tool that is created to help us better understand or interact in the world around us.
  • Review Chapter 1 and discuss how technology shapes science and how science shapes technology.
  • Review the difference between independent and dependent Variables?
  • Independent Variable: This is the variable that you, the scientist, will change or control in the experiment. It's what you manipulate to see how it affects something else.
  • Dependent Variable: This is the variable that you measure or observe. It depends on the changes you make to the independent variable.
  • Discuss how creators of technology create new ways to vary, use, or determine both independent and dependent variables.

  • After logging in, students will be taken to their TinkerCad dashboard.
  • Provide a brief overview of the dashboard, highlighting key features.

Create New Design:

  • Have students click on the "Create new design" button.
  • Inform them that this will open up the main workspace where they can start building their project.

Step 3: Design A 3D Model or Circuit

Choose Your Workspace:

  • 3D Design: Ensure students select the "3D Design" workspace if they're creating a 3D model.
  • Circuits: If working on an electronic project, instruct them to switch to the "Circuits" workspace.

Building A Model:

3D Design:

  • Guide students to drag and drop basic shapes (like boxes, cylinders, and spheres) from the right sidebar onto the workplane.
  • Encourage them to adjust the size, color, and position of these shapes and combine them to create their desired model.
  • Show them how to click and drag to select multiple shapes, then use the group function to combine them into a single object.

Circuits:

  • Instruct students to drag and drop components like resistors, LEDs, and batteries onto the workspace from the right sidebar.
  • Demonstrate using the wiring tool to connect components and create their circuit.
  • Have them click the "Start Simulation" button to test their circuit and see it in action.

Step 4: Save, Export, and Share

Saving The Project: Inform students that TinkerCad automatically saves their work as they go, but it's a good practice to manually click the "Save" button to ensure their project is saved.

Export Your Design:

  • 3D Models: Guide students to click on the "Export" button to download their design as an STL or OBJ file for 3D printing.
  • Circuits: Instruct them to click on "Download" to save their circuit design or export it to another format.

Share The Project: Show students how to use the "Share" button to get a link to their project. They can share this link with friends, teachers, or collaborators to showcase their work or get feedback.

Analyze

  • Encourage students to look for patterns or interesting findings in their observations. How would using AR help them understand the science phenomena better?
  • Based on their observations, what can they conclude about the power of augmented reality in learning science?
  • Have students think about how AR technology can be used in other areas of education and everyday life. Encourage them to share their thoughts with classmates.
