Genetic Vocabulary Practice
What to do
• Open a blank page in Educreations or Notability
• I will show you a word or letter(s)
• You WRITE what it means, and add a PICTURE/EXAMPLE if you can.
For Example
• If I said “Cell”
• You could write something like “the smallest basic unit of life.”
and
• You could draw a cell
