90 Degrees Education

A tidy living room coffee table transformed into a mini engineering lab: an open cardboard box spilling out assorted building materials like bright plastic gears, wide rubber bands, craft sticks, and cardboard tubes. At the center, a half-assembled, whimsical rubber-band-powered car sits on the table, with small sticky notes nearby showing sketched diagrams and simple force arrows. Warm, indirect golden-hour light enters from a side window, casting longer, soft shadows that highlight textures in the cardboard and wood grain. Photographic realism with a three-quarter angle, balanced composition using the rule of thirds, playful and inventive atmosphere, subtle bokeh on a couch and bookshelf in the background to keep focus on the DIY engineering project.

STEM Activity Blog

A blog-style list updates regularly with new activities, sortable by age, subject, and difficulty to fit your family’s learning pace.

A large, transparent plastic bin on a smooth laminate floor, filled with water and floating STEM objects: foam cubes numbered with bold digits, a small plastic boat with a paper flag labeled with a simple formula, and metallic washers sinking to the bottom to illustrate density. A laminated chart with colorful icons explaining "sink or float" leans against the side of the bin. Natural afternoon light from a nearby window reflects off the water surface, creating sparkling highlights and soft ripples. Photographic realism, slightly elevated angle, moderate depth of field, playful and hands-on mood, with a tidy, neutral-toned living room softly blurred in the background to emphasize practical, at-home science exploration.

Our gallery showcases finished projects and in-progress experiments to inspire your young scientists and help parents imagine what to try next.

A bright wooden kitchen table covered with a neatly arranged STEM activity setup: transparent plastic measuring cups filled with vividly colored liquids, a clear glass jar mid-reaction with bubbly foam rising, and neatly labeled index cards showing simple math equations and science terms. In the background, a blurred view of a clean, modern kitchen with stainless steel appliances and a sunlit window. Soft morning natural light streams in from the side, creating gentle reflections on the glass and glossy table surface. Photographic realism, eye-level composition with shallow depth of field, playful and inviting mood, vibrant colors, and a clean, family-friendly aesthetic that emphasizes simple, practical at-home experiments without any people visible.
