Within the scope of science popularization activities Karolina Wojtulewicz, PhD, from our Institute has organised ‘Kitchen laboratory’ classes with the children form nursery school Dreamland in Brwinów. Small scientists observed how the red cabbage juice is changing after adding different substances, checked if banana has DNA, and prepared beautiful oil lava. Also, they learned how to make a note/report of an experiment conducted, and what is needed in the laboratory to ensure safe and professional work.
