Yesterday the Primary 1 pupils visited our class to show and discuss their learning as part of Science Week. They showed the P6/7 pupils the wormeries they had made. The P6/7 pupils were very engaged when listening to the confident P1 pupils sharing what they had been up to and everything they had learned. The P6/7 pupils were excellent role models showing great listening skills and respect toward the younger pupils.
Mrs Hosie returned on Monday this week to deliver lessons on chemical reactions to each class. During these lessons Mrs Hosie involved the pupils in the coke and Mentos experiment. The pupils were encouraged to think of a hypothesis, before the experiment then consider the reasons for the chemical reaction that took place. They learned that when the Mentos sink to the bottom of the cola bottle, carbon dioxide bubbles are created. As the bubbles risethey react with more carbon dioxide which is still in the cola building up lots of pressure which creates an eruption of the liquid.
We were very lucky to have two lecturers (Derek and Shona) from Ayrshire college today and deliver an excellent and informative workshop to our class. They set up a crime scene (The Case of the Missing Sweets) and explained different aspects of evidence. The pupils worked round different stations to analyse evidence samples, carrying out a range of tests. This helped the pupils to identify the prime suspect who turned out to be Mr Houston. Different stations included, chromatography (testing the ink from the ransom note), fingerprints (identifying different types of finger print and determining which suspect’s print matched the crime scene print), FITR (Fourier-Transform Infrared Spectroscopy) to analyse the sticky sweet residue and pH sampling (saliva sample). Finally, Shona demonstrated a flame test using different soil samples which the pupils loved as each sample gave off a different coloured flame due to containing different chemicals (based on where they have come from).
The workshop was so engaging and the pupils all had great fun whilst learning lots of new skills. Derek and Shona commented on how they enjoyed visiting the school and seeing the excitement among the pupils.
