The weather forecast.

Finally we have spring here in Olsztyn-Poland. But the weather is perfect for summer. We invited the weather presenter from our local TV station and she told us about her work. Children could try her hand in presenting the weather for our region.

Materials:

• Shallow bowl 
• Water
• Pepper
• Dish soap
• Toothpick or a finger 
• Paper
• Pencil

Procedure

1. Fill the bowl with water.
2. Sprinkle pepper evenly across the surface. 
3. Squeeze a tiny bubble of dish soap onto a clean counter.
4. Touch the tip of your  finger to the bubble of dish soap. 
5. What do you think will happen when you touch your soapy toothpick to the water? How will the pepper flakes react?

As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap, and carry the pepper along with them.

Rosetta in Olsztyn.

We learnt about Rosetta and its mission. Students were very interested in this topic. We had lots of fun to make a model of Rosetta.
