"Our daughter, age 7, participated in a recent STEM exercise via group ZOOM call. We really like how the teacher, challenged the children to think about the problem and alternative solutions. Amazingly well done, start to finish. If you are looking to add to your child's experience in science, this is it."
"My child is enjoying the program very much. For her it is something interesting to look forward aside her school work, in which she is losing interest now."
"So you definitely did something right in instilling a confidence and a desire for inquiry in them that I haven’t seen before. The experience definitely exposed them to something more than they would have had in their district and yes I teach science but what you did surpassed the standards. There is a silver lining in this storm of remote learning."
