Christmas STEM Activities for Kids – 12 Science Experiments & Challenge Cards (Printable, Ages 5–10)

What you get

Make the holidays a little more curious. Christmas STEM Lab is a printable science pack for children ages 5–10. Kids race candy canes in cold and warm water, make raisins dance, cut six-sided paper snowflakes, build cup trees and marshmallow towers, pick up "snow" with a static balloon, time melting ice snowmen, fly a paper sleigh glider and grow salt crystal stars. Every experiment uses things you probably already have at home.

Each experiment comes with a lab page and a record sheet. The lab page lists materials, numbered steps, a safety box and "The Science", a short kid-friendly explanation of what really happened. The record sheet walks children through the scientific method: predict, observe (data table and drawing space) and explain, with a word bank for younger scientists.

What's included (42 pages, US Letter + A4 PDFs):

1. Grown-up guide - how to run an experiment, tips for ages 5–7 and 8–10, classroom group roles and station ideas
2. Safety notes for grown-ups - hazard table (hot water, choking hazards, balloons, magnets, sharp points, allergies, salt, launching)
3. Lab safety rules - 10 kid-friendly rules and a lab promise
4. How scientists work - ask, predict, test, observe, explain, plus what a fair test is
5. Materials checklist - everything you need, with the experiment numbers that use it
6. 12 experiments, each with a lab page and a record sheet (24 pages): Candy Cane Dissolve Race, Dancing Raisins, Paper Snowflake Symmetry, Build the Tallest Cup Tree, Marshmallow Star Structures, Static Snow Balloon, Melting Snowman Race, Paper Sleigh Glider, Snowflake vs. Coin Drop, Frosting Color Lab, North Pole Magnet Maze, Salt Crystal Star Ornament
7. Printable North Pole magnet maze with cut-out tokens
8. 12 STEM challenge cards (4 per page, cut apart) - paper chain, gift box bridge, tree tower, parachute, snowball launcher, foil boat, ornament mobile, ramp race, straw blow race, card house, smart wrapping and an unplugged coding grid
9. Challenge tracker and Design your own experiment page
10. Science words - a 16-word word wall
11. Junior Scientist certificate
12. What should happen - expected results for all 12 experiments, plus maze and coding answer keys

Why you'll like it - Science explanations are short, simple and accurate, so you can answer the "but why?" questions - No fire, candles, borax, dry ice, hydrogen peroxide or strong chemicals anywhere in the book - Grown-up steps and adult supervision are clearly marked on every experiment - Secular winter and Christmas theme (candy canes, snowflakes, trees, sleighs, reindeer); original illustrations, no licensed characters - Great for winter break, homeschool, classroom stations, science clubs and December countdowns

Please note - This is a digital product. No physical item will be shipped. - Adult supervision is required for every experiment. Some experiments use small items (candy, raisins, marshmallows, balloons, coins, paper clips, a magnet) that are choking hazards for young children; hot water steps are for grown-ups only. - Results can vary with room temperature, materials and technique. - Colors may look slightly different depending on your screen and printer. - For personal, family and single-classroom use only.
