The cookies and Milk Experiment

By Madison Christensen

Big Question

Which cookie will hold the most milk?

Hypothesis

• I think that the hard Chips Ahoy cookies will hold the most milk because the hard Chips Ahoy cookies have no moisture and unfilled air bubbles.

Interesting facts from research

• Cookies are full of pores. These pores are empty spaces which allow the milk to enter into them.

• The chunky Chips Ahoy cookie has been a very popular cookie to dip in milk.

Materials

• Hard Chips Ahoy cookies• Soft Chips Ahoy cookies• Oreo cookies• Cookies all covered in hardened fudge• Gram scale• Glass of milk • Piece of paper • Pencil

Step by step instructions

1. Use a weighing scale ( in grams) to measure each cookie. Write down the grams each one weighs.

2. Get a glass of milk out and then dunk a cookie in it for 10 seconds.

3. Use the scale to weigh it then record how many grams it weighs.

4. Repeat step 2 - 3 for each cookie. Also write down how much they weigh after being dunked in milk.

5. Subtract their weight when they weren`t dunked to the weight when they were dunked.

6. Find which cookie changed the most in weight by finding the biggest sum of answers.

Observations

• When I dunked the cookie that was all covered in hardened fudge, it actually absorbed some milk when I thought it wouldn`t.

• The hard Chips Ahoy cookies and the soft Chips Ahoy cookies weighed 230 grams before being dunked
