Over a score of upper school girls from the Women in Science, Technology, Engineering and Mathematics (WiSTEM) club traveled to Harker Preschool to do science activities with the littlest Harker students.

The visitors, 23 upper school students and 15 preschool parent volunteers, worked with 75 preschoolers on a variety of fun tasks, including exploring milk paint, which involves using soap to move color through milk. Other activities included generating static electricity with wool and plastic rods to attract paper bits; using a microscope and digital imager to look at leaf structures; using filter paper and marker ink to separate colors; making giant bubbles; and looking at preserved octopi, bats, birds, snakes, insects, sea shells and a sea star. The students also collaborated in a Lego Engineering math game. “The children had a great time,” noted Robyn Stone, STEM specialist for the preschool. “Preschool parents were very impressed by the Women in STEM’s passion for science and their ability to communicate with our young scientists,” she added.
