Using a digital microscope (i.e. ”Web ägget” or Wifi puck), you shoot images taken with a microscope.
Then have the children try to pair the images with the right object using the microscope. Here it is important to examine carefully as the image may have been taken by a small detail of the object you are studying.
Hint: use magnifying glass as a complement!
Then let the kids look for exciting objects, take their own photos and challenge each other.
Try to draw from your fantastic pictures.
