Ovo je jednostavan eksperiment kojim djeci možete predočiti kako nastaje duga i uvesti ih u očaravajući svijet fizike. Aktivnost također spada u STEM aktivnosti, a više o STEM-u možete pročitati u Što je stem?.
This is a simple experiment that can help children understand how a rainbow is formed and introduce them to the fascinating world of physics. The activity also falls under STEM learning.
Uvod u eksperiment/INTRODUCING THE EXPERIMENT
Before starting the experiment, ask the children what they know about rainbows — when they appear and how they are formed. You can also watch a few educational videos on YouTube channels, for example:
Right before starting the experiment, use visual aids to explain to the children that a rainbow is formed when white sunlight passes through raindrops, where the light bends and splits into the colors of the rainbow spectrum. Tell them that with a simple experiment, they can create a rainbow themselves.
After completing the experiment and discussing it, I suggest an art activity where children draw with markers or colored pencils on the topic “How a Rainbow Is Formed.” The goal of this activity is to document their newly acquired knowledge and understanding.
Priča: JAJE KOJE NIJE ZNALO KOJU BOJU VOLI
For the experiment, you will need:
- a CD placed at an angle in a glass container filled with water (to imitate a raindrop)
- a flashlight
- black and white paper to reflect the rainbow (optional: the light can also be reflected on a wall)
Za eksperiment ćete trebati:
- cd položen pod kutom u staklenu posudu s vodom (imitacija kapljice vode)
- ručna svjetiljka
- crni i bijeli papir na kojemu ćemo reflektirati dugu (opcionalno: svjetlost se može reflektirati i na zidu)
Papir položite okomito ispred posude s cd-om. Kada uperite svjetlost prema cd-u duga će se reflektirati na papiru kao na slikama.
Nakon odrađenog eksperimeta i razgovora o istome predlažem likovnu aktivnost crtanja flomasterima ili drvenim bojicama "Kako nastaje duga"s ciljem dokumentiranja usvojenih znanja ispoznaja.
