An exploratory and descriptive research with a quantitative approach was carried out in order to describe the situation of the experimental activities during the COVID-19 pandemic. It considered the teachers’ point of view. 450 Physic, Chemistry and Biology teachers of Secondary level, University and Teacher Education, voluntarily participated in an online survey in June of 2021. The outcomes of three questions about frequency, relevance and type of experimental activities in emergency remote teaching settings are discussed here. Although the teachers stated the high relevance of these activities, the frequency of them in their classes was around 23%. The predominant types were the home-made (53%) and the video or stream (51%). These results show the extreme necessity to develop new theoretical and methodological models to support the experimental activities in educative settings mediated by technologies.
