Information about Glow in the Dark

1. WALT :

Make connections between different sources of information.

Meaning of WALT - Make links between different websites or videos of information.

2. Collection of Information :

Glow in the Dark known as Luminescence simply requires chemicals that store energy into the light.

These special substances are called phosphors (Different wording - Phosphorescence).

Make sure the expose the item to a light for a while so that it could glow in the dark again.

Chemiluminescence makes the object glow in the dark because of the chemical reaction.

Phosphors found in glow-in-the-dark toys are zinc sulfide and strontium aluminate.  

Radioluminescence uses phosphors that are constantly charged by adding radioactive elements, such as radium, to them.

One from nature is Bioluminescence. Some creatures, such as fireflies and jellyfishes, contain chemicals within them the causes things to glow. Some creates glow for protection.

Science Intensive with Room 7

In our first lesson for science intensive, we were learning about Glow in the Dark. This lesson was very fun and all students learnt a lot. As for our students, we learnt how to make our own black light with just using a torch and two different coloured cellophane and create our own glowing water with just water and a highlighter. These were simple and we also learnt a lot of things by watching videos. 

Here is a drawing of my Glow in the Dark...
