Christmas STEM Science Experiments KS1

Fourteen real Christmas science experiments for KS1, with a prediction page, a results page and the working scientifically method built into every one.

Chemistry, physics and engineering from kitchen and classroom materials, with a full checklist. No specialist equipment.

What children will explore

• Working scientifically - predict, test, observe, record, conclude
• Chemistry - dissolving, acids and bases, chromatography, crystals, density
• Physics - static electricity, magnetism, insulation, sound absorption
• Engineering - structures, stability and forces, in three challenges

The fourteen experiments

• Candy cane dissolving race - which liquid dissolves sugar fastest
• Candy cane colour separation - chromatography on filter paper
• Crystal snowflake growing - with a three-day observation journal
• Snow volcano - an acid and base reaction
• Cranberry colour magic - juice as a natural pH indicator
• Density column - honey, syrup, water and oil, then drop objects in
• Static tinsel - a balloon, a woolly jumper, no touching
• Insulation test - which material keeps ice frozen longest
• Frozen bubbles - ice crystals forming on a sub-zero morning
• Magnetic Christmas - testing eight objects with a magnet
• Jingle bell sound test - which materials absorb vibrations
• Gingerbread engineering - build a house that stands up
• Marshmallow towers - cocktail sticks, marshmallows, a wide base
• Balloon sleigh race - Newton’s third law along a string

What’s inside - 43 pages

• Fourteen experiment cards with method, prediction and results pages
• Sorting across chemistry, physics and engineering, plus vocabulary tracing
• Comprehension story, sequencing, true-or-myth and equipment labelling
• Shadow matching, a counting scene and a laboratory colouring page
• Design your own experiment, a progress chart and an answer key

Why teachers and parents love this pack

• A prediction is recorded first, so the method is taught, not the result alone
• Independence badges mark what needs an adult and what children can run alone
• Materials come from the cupboard - vinegar, marshmallows, balloons, bells
• Suits a December science club, an end-of-term carousel or a holiday project
