Demonstrate the difference between saturated and unsaturated solutions (crystal-growing lesson; an early start on a Grade 7 outcome).
The Manitoba Science, Kindergarten to Grade 8 outcome 7-2-22 (Cluster 2: Mixtures and Solutions) for Grade 7 says: “Demonstrate the difference between saturated and unsaturated solutions (crystal-growing lesson; an early start on a Grade 7 outcome).” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Manitoba Science, Kindergarten to Grade 8.
Earth and Sky at Home Grades K–5
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.
- Where do rainbows come from? 45 min, plus 10 min outside on a sunny day
Children split sunlight into colours with a glass of water, test whether the water is what makes the rainbow, and make their own rainbow with a hose mist. They finish able to explain that white light is a mix of colours that water bends apart.
- 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.
- How does a cloud form? 40 min
Children watch the grown-up set up two jars of hot water with ice on top, add a wisp of smoke to one, and compare the clouds. They finish able to explain that clouds form when moist air cools and water collects on tiny specks.
