Explore the fat in different milks by watching the colors swirl and mix. Using the scientific method students will investigate the question:
Does the amount of fat in milk affect the amount of swirling colors?
This investigation is in the process of being updated. A new K-1 version is available. This download will become a bundle containing the K-1st, 2nd-3rd, and 4th-5th grade versions by the end of October 2018. Purchase today for the low price before the bundle is added or download the new K-1st grade version at the link below.
Students will discover that whole milk is made mostly of water, but it contains fat. The fat can be separated from the milk using soap. The food coloring enables us to see the fat separating. This investigation journal meets the *Next Generation Science Standards 2nd Grade Benchmarks for Structure and Properties of Matter (2-PS1-1 and 2-PS1-2) and K-2 Engineering Design (K-2-ETS1-3).
Students will love the beauty of the swirling colors. Teachers will love its’ ease of use and watching the students get excited about science and using higher order thinking skills.
Great activity for St. Patrick’s Day. Perfect for classrooms, homeschooling, science fairs, scout groups, or just fun.
