1) Get one more note card for each stack you’ve made.
2) Think of a topic sentence that introduces the information in a stack. You'll need to write one topic sentence for each stack.
For example, the notes in the “diet” stack mention many different sources for food. So, a topic sentence could
“The European Hornet eats both animals and plants”.
Sometimes it’s a good idea to avoid using the actual word for the topic in the topic sentence. Notice that the
sentence doesn’t actually say “diet” but uses words to get that idea across.
