# Real-World Application with STEM Lessons in 3D!

Boost STEM learning outcomes by using 3D pens to design prototypes and engage students in real-world thinking.

With 3D printed models, students are able to observe characteristics of objects that can be more challenging to comprehend through 2D worksheets or textbooks. For example, students can create models of cells, atoms or historical buildings that would otherwise be inaccessible in a classroom. By creating and examining models hands-on, non-visual learners gain accessibility to educational concepts that would otherwise be out of reach. With 3D printing pens, students gain confidence in STEM subjects by exploring real-world topics in 3D with direct application, engaging in creative thinking and open ended problem-solving.

3Doodler offers an extensive library of resources to educators and we’re sharing our top STEM lesson plans for the in-person, remote, or hybrid learning settings for the 2020-21 school year.

## Geometric Collage Maker

Learn about: Geometric shapes, how to calculate area and perimeter
Overview:  In this lesson, students create a Doodled collage of geometric shapes, resulting in crayon rubbings used to calculate the area and perimeter of combined shapes.

## Geometry & Tessellations

Learn about: Geometric shapes and problem solving through design
Overview: Students will design a simple tessellation for a 3D shape such as a cube, a cylinder, or a cone using 2D templates. Students will enjoy seeing their designs come together in 3D, and will even be able to use it as a functional item, such as a pen holder!

## Construct a 3Doodler City

Learn about: City planning, geometry, area and perimeter calculations
Overview: Students will identify the structures that make up a city (e.g. roads, buildings, bridges), and then analyze the way in which these structures are composed of lines and geometric shapes. Students will design 2D shapes and then Doodle over them to construct their own 3D structures. This real-world, hands-on project combines math, problem solving, and technology.

## Prokaryotic & Eukaryotic Cells

Learn about: Biology, cell structure, prokaryotic cells and eukaryotic cells
Overview: In this activity, students will Doodle two cell models, one of a prokaryotic cell, and one of a eukaryotic cell. The students will build all parts in each model such as the nucleus, plasma, cytoplasm, mitochondrion, etc. The students will analyze and record the differences and similarities between the two cells.
