In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals.
Hypothesis. The hypothesis is that the crystals will grow best in warm temperature. Method & Materials. You will purchase a crystal growing kit, gather materials, mix solutions, place dishes with crystal solutions in different temperatures, observe and record growth, and dump solutions from dishes.
See how to grow crystals of sugar, salt, borax, alum, and many common chemicals. Get recipes to grow crystals using household ingredients.
Growing Crystals. From the Centre for Science Education, and with support from Shell Education services, these materials help children to grow large crystals using salt solution. The crystals take about a week to grow.
Background and National Curriculum links. These activities are intended for two lessons for Year 7-9 students, focusing on crystals. In the first lesson, students consider substances they think are crystals, compare these with substances that are crystalline, and set up crystal growing experiments. In the second lesson, they examine the results ...
Step-by-step instructions for basic crystal growing experiments; Ideas for variables to test and how to display your results; Safety precautions for grown crystals at home; So let’s get started with the magical science of growing crystals!
In this chemistry science project, you will discover the best temperature conditions for making the largest, purest crystals by growing your own crystals out of borax (a home cleaning product) in different temperature conditions.
