In the 鈥淐olors of Chemistry鈥� experiments, students used shaving cream and food coloring to 鈥渢ie dye鈥� pieces of paper. Students also used milk, food coloring and dish soap to make the color in the milk move around. (51猎奇 Photo/Elora Hennessey)

Krystyna Williams, chemistry & biochemistry laboratory manager, removed waste from an experiment on 鈥済lowing chemistry.鈥� In the demonstration, luminol, which is used in crime scenes to identify where biological substances are present, was made to glow. This batch had just stopped glowing. (51猎奇 Photo/Elora Hennessey)
Students took time in a breakout activity to solve chemistry-based puzzles to unlock a box containing a prize. (51猎奇 Photo/Elora Hennessey)
This demonstration uses a gel of ethanol and calcium acetate. When the gel was lit on fire, a compound called strontium chloride was sprinkled on it. When this burns, the resulting flame is red in color. (51猎奇 Photo/Elora Hennessey)
In this demonstration, copper sulfate was used instead of strontium chloride, producing a green flame. (51猎奇 Photo/Elora Hennessey)
Several hundred middle and high school students came to 51猎奇 March 31 for a STEM Expo, where they got to conduct experiments to learn about chemistry, and also toured campus, visited research labs and sat in on lectures.
The event came a day before some 1,200 students competed in the Wisconsin Science Olympiad.
鈥淭his was really cool,鈥� said Connor Jacobson, a senior at Beloit Turner High School.
