Brainstorming
• What kinds of things hurt your stomach?
• What might soothe your stomach?
• What are some ways to keep medicine from
hurting your stomach?
Digestive System Anatomy
Your Challenge
• Your team will create an “enteric” coating for a
pill that can protect it from a simulated acidic
environment (stomach).
• You will be provided the Following Materials:
–
–
–
–
–
Oil
Sugar
Flour
Corn Starch
Candy (your pill to protect)
Brainstorm
• As a team, take 5 minutes to discuss and
decide on an initial recipe for your pill coating
• Write your initial recipe on your worksheet
Build!
• As a team, gather the ingredients (in the
correct proportion that you need) and start to
mix your coating
• If you need to adjust your recipe, that is ok!
Make sure to document what your ending
recipe ends up being.
• Coat your pill and be ready to test.
Test!
• Each team should label their cup and bring it
up to the front.
• We will test each team’s pill against a control
pill (1 Skittle with no coating)
• After 10 minutes, we’ll gather data on which
pills worked and what recipes were used
• Write your team’s recipe up on the
whiteboard to share with the class
CREATIVE TIME
• While we wait for our test to be finished:
• As a team, come up with a commercial or ad to
try to sell your candy coating to manufacturers.
• Your commercial/ad can be in the form of a skit,
song, rap, dance, poster, art…or something else
creative!
• We’ll share these during our next CREATIVE TIME
Reflect!
• Record the results of your test next to your
recipe
Is the coating still intact?
Does your candy still have it’s color?
Has your candy started to dissolve?
• Can anyone see any trends with which
coatings survived and what
ingredients/fractions were used?
ITERATE!!!
• Based on the results of the first test, let’s try
this again!
• This time, you must write down your recipe
for your coating and stick to it…no
adjustments!
• Coat your candy and be ready to test again!
ITERATE!!!
• Let’s test again!
• While we wait…who wants to share their
commercial/ad?
Report Time!
• What did we learn today?
• Why did we test in the Sprite? Why didn’t we
have someone swallow our “pill” and see how
it lasted?
Today’s Video!
• Now let’s watch how pills are made!
