AHHAA gets soaked!

11:30-12:30 – Workshop: Diving Squids

Squids are master swimmers but how do they really swim? And how – and why – do they dive? Did you know that the diving “mechanism” of squids and submarines is basically the same? In this workshop, we’ll build the “squid tanks”, where you can make the squids move up and down as if by magic!


13:00-13:45 – A science show called ‘Wondrous Water’

Where did water come from? This is the first thing you’ll going to find out. Of course, we’re not going to stop there, so when we’ve created water, we’ll show you how wondrous such a simple substance actually is. Considering the nature of this science theatre show, you’ll also see a surprising amount of fire and explosions.

14:00-15:00 – Workshop: Fish Necropsy

All the participants will get an opportunity to identify the fish species, its internal organs, measure the length and determine the sex of the fish. The person carrying out the workshop will also explain the causes of high concertation of heavy metals in oceans and how this affects first the health of fish and then then health of fist-eating humans.

15:00-16:00 – Laboratory work: corals and coral reefs

Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. Why are the colonies of corals essential and how exactly are they formed?

16:00-17:00 – Science show called “Human Health- Viral Pathogenesis”

This science show presents general knowledge on autopsies and pathogenesis using a special life-sized autopsy doll of a grown man.At the beginning of the show an autopsy table is placed in the middle of the room so that the participants can see the doll perfectly. The performer presents the process of autopsy to the participants and talks about what which will happen to the human body after and introduce the organs as well.

17:00-18:00 – Workshop: the salinity of sea water

The salinity of the Baltic Sea is much lower than that of ocean water, which is due to abundant freshwater runoff from the surrounding land, combined with the shallowness of the sea itself. In the workshop all the participants will compare the salinity of water of the Baltic Sea to other sea/ocean waters. The participants will mix solutions with different amount of salt to get the real salinity for the ocean waters. After making the solutions they will compare the results (by tasting the solutions) and try to figure out the reason of the differences between the geographical locations of the seas and oceans.

18:00-20:00 – Science Café: the impact of pollutants on the health of fish and humans

The speaker of the science café will be PhD Arvo Tuvikene, a professor of biology at the Estonian University of Life Sciences. The science café will address the topic of the pollutants, e.g. heavy metals, in the Baltic Sea and the impact they have on fish and on the health of fish-eating humans.
