1. The cookies and Milk Experiment
By Madison Christensen

2. Which cookie will hold the most milk?
Big Question
Which cookie will hold the most milk?

3. 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.

4. 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.

5. 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

6. Step by step instructions
Use a weighing scale ( in grams) to measure each cookie. Write down the grams each one weighs.
Get a glass of milk out and then dunk a cookie in it for 10 seconds.
Use the scale to weigh it then record how many grams it weighs.
Repeat step for each cookie. Also write down how much they weigh after being dunked in milk.
Subtract their weight when they weren`t dunked to the weight when they were dunked.
Find which cookie changed the most in weight by finding the biggest sum of answers.

7. 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

8. Data (in grams)

9. Analysis of data
The cookie that gained the most milk was the hard Chips Ahoy cookie with 120 grams gained

10. Conclusion
My conclusion is that the Hard Chips Ahoy cookies hold the most milk and if you love cookies to absorb a lot of milk the best cookie to use is Hard Chips Ahoy cookies.
