Glowing Ice Cream??

For homework, students were asked to read an article in a Super Science magazine titled "Glowing Ice Cream".
A British inventor has created an ice cream that glows by using the protein from jellyfish. The flavor is called Bioluminescent Jellyfish.

When he licked it, the warmth from his tongue made the ice cream glow!

One scoop costs $230!!

Students were asked to read about it and respond in the form of YES! I would totally eat that OR NO way! I would NOT eat that!! Then they had to support thier answer with an explaination.

Here are just a few samples...

And my question for you is, would YOU eat glowing ice cream??





Merry Christmas from Room 219

The students did a fabulous job when given the task of creating ornaments for our class tree. Each ornament had to be a representation of something we have learned so far this year in Math and/or Science.

We've learned a lot and the ornaments show that wonderfully!

Our tree looks fantastic!!

Lighten Up!

One of the properties of Light is brightness or intensity. To demonstrate that the intensity of light becomes less when the source is farther away and the intensity becomes more when the source is closer, we conducted an experiment.

Students had to place a flashlight 2 centimeters above their paper and record the size of the circle of light. They continue to do this, 2 centimeters at a time until the circle of light went off the paper.

The results proved that the farther away the light was from the paper, the dimmer the light was and the wider the circle became.











Another property of light is making things VISIBLE and identifying the COLORS of light in the VISIBLE SPECTRUM



An object is VISIBLE only if it is a source of light or it reflects light.

Sources of Light come in 3 categories:

Direct/Natural Light
Sun, stars, magma/lava
 

Indirect/Man Made Light
fireflies, fire, candles, light bulbs

 

Reflected Light (not an actual source, it reflects light from another source)
moon, planets, mirrors


Transparent, Translucent, & Opaque

Light behaves differently when it strikes different objects.

Transparent materials allow all light to pass through. Objects can be seen clearly.


Translucent materials allow some light to pass through. Some light passes through and some light is absorbed. Objects appear as blurry shapes.


Opaque materials do not allow any light to pass through.
All light is either reflected or absorbed.



Reflection and Absorbtion

Objects appear to us as certain colors depending on the color that the object is reflecting.

A green apple REFLECTS green and ABSORBS (takes in) red, orange, yellow, blue, indigo, and violet.

A banana REFLECTS yellow and ABSORBS (takes in)  red, orange, green, blue, indigo, and violet.

Black ABSORBS all colors.
White REFLECTS all colors.

The Visible Spectrum

White light is made up of many colors.
White light enters a prism and separates into the colors.
Red, orange, yellow, green, blue, indigo, and violet
Also known as ROYGBIV

Light travels in a straight line.

Light is a form of energy. (the ability to make something move, change, or happen)
Refraction is the bending of light.
