Greg DeFrance, top left, and his children, from left, Eric, 10, Lucy, 4, and Raymond, 11, check out a plasma ball during Family Day at the Wyoming State Museum in Cheyenne on Saturday. Raymond, in particular, has shown a keen interest in science. According to Greg, that morning, Raymond had taken apart a robot to see what was inside. “He was able to put it back together. But I had told him, ‘If you break it, I don’t care,’” recalled Greg. “It had a lot of gears and microchips,” reported Raymond with a smile.
