Materials List: Exploring the Integumentary Systems of Animals

For Motivation/Introduction Activity:

Each group will need:

  • various types of sunscreen; one different type per group (for example: sprays, lotions, organic sunscreen, inorganic metallic sunscreen, zinc, etc.)

To share with the entire class:

For the Main Activity:

Each group will need:

  • Sample Procedures worksheet; three copies per student
  • Control Lab Procedures worksheet; two copies per student
  • Testing Apparatus Construction presentation and Data Collection worksheet; one copy per group
  • Conclusion Poster Layout worksheet, one copy per group
  • hot plate
  • 1000 ml beaker
  • two 250 ml beakers (students will use one while the other cools following use on the hot plate)
  • 100 ml graduated cylinder
  • two 10 ml graduated cylinders (one for measuring vinegar; one for measuring glycerin)
  • permanent marker
  • silicon spatula, available on Amazon and in other stores
  • timer (students may use smartphones)
  • electronic balance
  • metal spatula (one large enough to measure 10 g of corn starch and other for measuring 0.6 g of glowing powder)
  • weighing paper (used in chemistry classrooms)
  • weighing boat (used in chemistry classrooms)
  • five petri dishes
  • ~60 g corn starch
  • ~30 ml vinegar
  • ~30 ml glycerin
  • ~300 ml distilled water (tap water will work for this activity)
  • ~3 g red phosphorescent (daytime white-glow) powder, available online
  • pipettes (one for vinegar, one for glycerin)
  • additional materials needed for different groups; note: all of these items can be purchased in department store craft section, craft store, or online:
    • group 1: feathers, ~10 cm in length
    • group 2: chocolate protein powder or coffee grounds, ~30 g
    • group 3: yellow food coloring, 1 vial
    • group 4: acrylic nails, 50 count bag
    • group 5: brown plastic lacing thread
    • group 6: green glitter, 100 g jar
    • group 7: see Student Sample Examples and Cuticle Procedures

To construct the quantitative testing apparatus; each group will need:

  • two ring stands
  • two clamps (that will fit a ring stand)
  • 1 cardboard box (approximate measure: 29.8 cm x 20.3 cm x 12 cm)
  • masking tape
  • box cutter
  • UV flashlight, available online
  • light sensor probe (can be purchased at Vernier; or check with your school’s science department)
  • LabQuest Interface or Lab Quest Mini (can be purchased at Vernier; or check with your school’s science department)
  • 25 – 50 g bottle of black acrylic paint

For evaluation of the activity, each group will need:

  • large dry erase board (60 cm x 80 cm) or poster board
  • dry erase markers or regular markers
  • meter sticks
