Grade 5 matter and materials
Solids, liquids and gases, properties of materials, mixtures and reactions. Here is what we have for Grade 5.
Lessons
Solids, Liquids and Gases
Where does a puddle go? Why does ice float? A first look at the tiny particles that explain the stuff around us.
Winter Science: Ice, Snow and Staying Warm
Why roads get salted, which mitten really works, how a seal stays warm in icy water, and why a mouse is cosier under the snow than on top of it. Four hands-on lessons on ice, heat and insulation.
Kitchen Chemistry for Families
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.
Keep It Cool: Ice, Insulation and Staying Comfortable
Why salt makes ice melt faster, which wrap keeps a drink coldest, how a seal and a fennec fox each keep their body temperature steady, and how to build a cool box that beats the heat. Four hands-on lessons that start from a freezer and work in any climate.
Clean Water Challenge: Mixtures, Dissolving and Separating
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.

Periodic Table Explorer
All 118 elements, coloured by family. Click one for its atomic number, mass, state, discovery and an everyday use, or highlight metals, gases and more.
States of Matter
Heat and cool a box of particles and watch them pack into a solid, slide as a liquid and fly apart as a gas, with a live thermometer.
pH Scale Explorer
Test household liquids on a pH scale with a cabbage-juice indicator colour, from lemon juice to bleach, and mix acids and bases to see neutralisation.
