I propose you a volunteer Do It Yourself practice about MAKING CRYSTALS.
Read the following information, and carry out this Lab Practice at home,
When finished, you should show to the teacher:
Your final crystals
And the Lab Report.
This Lab Report should include, as usual:
Title / Materials/ Procedure and Opinion or conclusion.
In the procedure you must include:
the STEPS TO MAKE CRYSTALS with
explanation
and drawing /or real picture.
Your Lab report wil be evaluated according to:
Presentation.
Scientific explanation of the process.
English grammar and accuracy
Complete description structured in steps.
Explicative drawings or pictures
Lab report structure
Even if you do not obtain a good crystal you should also do the LAB REPORT and boost your mark somehow.
he final result is not as important as the learning experience. Explain the process and reflect about why do you think it did not crystallize.
"Every failure is a step to success."
Make sure to show
your crystals and Lab Report
before the DEADLINE
This volunteer task could give you
up to 0.5 EXTRA POINT
in the coming exam.
To learn how to make crystals, check this out:

Your Lab report wil be evaluated according to:

As you can see, you could decide to use sugar for an edible crystal too... yummy!
Crystal geodes are also possible, you would need a special type of salt. Check out this web tutorial: https://www.stevespanglerscience.com/lab/experiments/incredible-egg-geode/ or the videos below.
NOTE: Alum or Borax are toxic and controlled products so you cannot acquire them without a certificate (sugar and salt are common and easy alternatives to it).
If you're hoping to incorporate crystals into a science project think about building a few different types of crystals and comparing their rate of growth, size, color, taste (when appropriate) and how long they last. You can discuss, like we did above, how crystals form and why. You could even try testing different materials to see if they will form crystal structures! Sugar forms crystals, does brown sugar form Crystals? How do they compare?
