that has a number of free online programs for elementary to high school students. One program is called VROC (or virtual researcher on call that connects specialists in the field with students) and the other is PIR Live Events (webinars). I have done several PIR Live events and been a part of webinars with inventors in the UK. Webinars cover a variety of STEM topics – from makerspace to cancer research. Students can pose questions and “chat” to the guests in real time. It was a great opportunity for students!
They also have their own YouTube channel and PIR TV to get students interested and enthusiastic about STEM.
