This is an experiment/craftivity that will dazzle your students, as they create a physical change with both the salt and the candle wax.
You can use any container to layer the colored salt, but I use baby food jars. I just collect them from my students throughout the year.
This STEM product includes a foldable which helps students:
S= Science: understand the difference between a physical change and a chemical change.
T= Technology: There is a technology component with links to Student Friendly sites for center work which allows your students to research the parts of a candle. [I'm also working on a webquest for this~ which should be out soon!]
E= Engineering: This gives your students a chance to demonstrate what they have learned about the science of candles when they create a model of a candle to show their learning.
M= There is actually quite a bit of math involved in the preparation of this project. I've added three multi-step problems for students to solve involving how much salt and wax to purchase, as well as how much string to use in making the wicks.
Two components in this Salt Craftivity that is not in my seasonal projects are: A look at Navajo Sand Painting and a Quick Write lesson.
I have done this for Christmas, Mother's Day, as a special science day, or when studying native Americans of the southwest. This will be an activity that students will always remember.
