*If you do not have a particular material, feel free to substitute something similar (make a paper funnel if you don't have a plastic one, etc.). I may also have suggestions for quick and easy to find substitutes during my instructions for each challenge. If a partner is needed, but one is unavailable for challenges, I will give students suggestions on how to complete the activity alone. As always, feel free to message me with material questions.
