Earth and Sky at Home Grades K–5 · partly supports this outcome

Make a rainbow on the kitchen floor, grow crystals on a windowsill and build a cloud in a jar. Three classic home experiments that actually work, with the real science explained for grown-ups.

• How do crystals grow? 40 min to set up, then 5 min a day for 5 to 7 days

  Children watch the grown-up make strong salt, Epsom salt and sugar solutions, set out dishes and a string, then check them every day for a week. They finish able to explain that crystals form when dissolved particles line up as the water leaves.

Kitchen Chemistry for Families Grades K–5 · partly supports this outcome

Four famous kitchen experiments, done properly: a homemade lava lamp, oobleck, a baking soda volcano and invisible ink. Each one starts with a real question, works with things from your cupboard, and leaves your child able to explain what happened.

• Is oobleck a solid or a liquid? 45 min

  Kids mix cornstarch and water into oobleck, then poke, squeeze, slap and drip it to find out when it acts like a solid and when it acts like a liquid. They finish able to explain why speed and force change the way it behaves.

• What makes a volcano erupt? 45 min

  Kids test baking soda and vinegar to find out where the fizz comes from, build the classic kitchen volcano, then open bottles of sparkling water to see what really drives an eruption: gas trapped under pressure. They finish able to explain how the model is like a real volcano, and how it isn't.

• How do spies write secret messages? 45–60 min

  Kids write invisible messages in baking soda, then reveal them by painting on grape juice or turmeric water, which change colour where the baking soda is. They finish able to explain that acids and bases make some colours change, and why a plain-water message stays hidden.

Clean Water Challenge: Mixtures, Dissolving and Separating Grade 5 · partly supports this outcome

Where does the salt go when it disappears in water? Can a filter make muddy water safe to drink? How do you get fresh water out of salt water? Three hands-on lessons on dissolving, separating mixtures and the solar still, with nothing tasted and nothing boiled by children.

• Where does the salt go when it disappears in water? 50–60 min

  Teams stir salt, sugar, sand and flour into water to sort what dissolves from what only mixes, then weigh a jar before and after to find out whether dissolved salt is really gone. They use the evidence to name three mystery powders and to explain, in their own words, why dissolving is not melting.

• Can a filter make muddy water safe to drink? 50–60 min

  Teams separate a made-up muddy, gritty, salty mixture by sieving, settling and filtering through cloth, a coffee filter and layers of gravel and sand, and score how clear each filter makes it. Then they find out what every filter missed: dissolved salt and dye, and germs, and why clear water is not the same as safe water.

Solids, Liquids and Gases Grade 5 · partly supports this outcome

Where does a puddle go? Why does ice float? A first look at the tiny particles that explain the stuff around us.

• Where does a puddle go? 50–60 min

  Teams race wet paper towels in still air, in wind, in a warm spot and under a cup to find out what makes water disappear faster. They catch the 'missing' water on the inside of the cup and explain evaporation with particles.

• Why does ice float? 50–60 min

  Students compare water before and after freezing: same weight, but more space. They float a block of ice, measure how much sticks out, and use particles to explain why lakes freeze from the top down and fish survive the winter.

Living with Water: Salt, Rice and the Mekong Grades 4–5 · partly supports this outcome

Science and English together, for English learners (CEFR A2–B1). Three investigations from Vietnam: how salt farmers turn the sea into salt, how rice terraces stop a mountain washing away, and how a house in the Mekong Delta stays dry in the flood season.

• How do salt farmers turn the sea into salt? 60 min, plus a 10-minute check the next day

  Science and English together, for English learners at CEFR A2–B1. Teams paint salt water on dark paper to find the salt hiding in sea water, then set out wide and narrow dishes in sun and shade to see what makes water leave fastest. They use the evidence to advise a salt farm in Khánh Hòa.
