Use the list of words below to summarize the lesson on hand sanitizers. You will need to use some words more than once:
neutrons, non-polar, soap, atoms, positive, polar, likes, electrons, lipids, molecule, water, protons, negative, coronavirus

1) A ________________________________________________ is the smallest piece of a substance that is still that substance. Page 2

2) If you break a ________________________________________________ down into smaller pieces, you will separate that substance into ________________________________________________. Page 2

3) Atoms are made of ________________________________________________, ________________________________________________, and
________________________________________________. Page 3

4) Protons have a ________________________________________________ charge. Page 3

5) Electrons have a ________________________________________________ charge. Page 3

6) If a molecule has a slight positive charge on one side and a slight negative charge on the other, we call that a ________________________________________________ molecule. Page 3

7) A molecule with balanced charges throughout is called ________________________________________________. Page 3

8) ________________________________________________ is a polar molecule. Page 3

9) Most fats are ________________________________________________. Page 3

10) “Likes dissolve ________________________________________________.” Page 4

11) A coronavirus is protected by a layer of ________________________________________________. Page 5

12) In this protective layer of ________________________________________________, the
________________________________________________ section of the lipid molecule faces outward. Page 5

13) This is why ________________________________________________ alone cannot destroy the coronavirus. Page 5

14) Both isopropyl alcohol and ________________________________________________ molecules have
________________________________________________ sections that attack the lipid layer of the
________________________________________________. Page 5

15) Between isopropyl alcohol and soap, ________________________________________________ usually destroys the coronavirus faster. Page 5
