SPF Challenge

Gather two or more sunscreen lotions with varying SPF levels. (This may be repeated with different brands of sunscreen or one brand offering varying SPF levels.)

Place a small amount of sunscreen on the back of your hand and massage into your skin. Wash off and repeat with other levels or brands.

Compare consistency, absorption, and then residue after washing the hand.

Repeat with each level of SPF and compare results.

  • Which SPF level felt the thickest?
  •  Which let like it most absorbed into your skin?
  • Which had the most remaining after washing the hand?
  • Which do you believe would best protect while in the sun?
