The PTA kicked off Science Saturday with a paint and plant activity. After painting their pots, families planted a succulent and learned how to care for their new plant.
Families learned thermodynamics of melting and freezing by making homemade ice cream! The combination of rock salt and ice water results in a transfer of energy. The energy produced from the salt and ice water mixture transfers to the liquid (milk, vanilla, sugar) changing it to a solid mixture a.k.a ice cream!
Families learned how salt can affect the properties and temperature of ice. When we add salt to the ice, it lowers the melting point of the ice. Since the ice is surrounded by very cold water, it quickly freezes again, causing ice to form again over the string!
What conducts electricity?
Families learned how to make a simple electrical circuit using only a few materials. They used their knowledge to create a unique Valentine's Day card.
Snowstorm in a cup / Tormenta de nieve en us vaso
Families created a snowstorm in a jar by combining water, oil and Alka-Seltzer. Since oil is less dense than water, the water sinks to the bottom of the jar. When the Alka-Seltzer is added to the jar, it creates pressure in an upward direction thus, pushing the water back down!
