Science Week 2022 in Rm1A ๐Ÿ”ฌ

20th Nov 2022

We had so much fun in Rm1A this week celebrating science week!

As part of science week, the children became detectives to solve the mystery of the missing trophy๐Ÿ†๐Ÿ”

In order to do this the children carried out the following experiments:

  • Taking and investigating fingerprints - children took prints and examined their own fingerprints, observing and classifying their fingerprints according to three basic ‘types’: loops, whorls and arches. The children then tried to match two fingerprints found at the crime scene with those from the four suspects to help solve the trophy mystery.
  • Chromatography experiment: children observed how black inks are a mixture of different colours and that these colours can be separated out through a process called chromatography. Through this experiment, the children discovered that one of the suspect's pens matched the ink on a note left at the crime scene.
  • Shoeprints: The children were busy examining a shoeprint found at the crime scene and comparing the print with shoeprints from the four suspects. The children made great observations and inferences regarding who they thought the shoeprint belonged to.
  • Mystery Powder experiment: Finally, the children had to identify a ‘mystery powder’ found at the crime scene. Children investigated 4 white powders and the mystery powder. In the first test, the children carefully examined each powder using different senses. In tests two and three the children added water and vinegar to the powders and observed what happened. The children learned when vinegar is added to baking soda the mixture fizzes, and this helped them solve the mystery.

 

We had great fun carrying out these experiments and we certainly have some great investigators in the class ๐Ÿ”๐Ÿ•ต๏ธ

Other experiments we carried out:

  • Floating and sinking ๐ŸŠ๐Ÿ’ง - We made predictions about whether oranges with and without skins would float.
  • Dancing Raisins ๐Ÿ•บ - showing how an object's density can change.
  • Self-inflating Balloon๐ŸŽˆ - Vinegar is an acid and baking soda is a base. When they react together they produce carbon dioxide gas which blows up the balloon.
