Raven smiled kindly and placed some of the red dust into the pot. Soon taking her wand out she said "Lumos" and pointed the light towards the plant. The plant turned a pretty shade of yellow while it hummed. She smiled at the Professor. She decided to keep that plant and take another one from the tray. She relevitated a plant towards her and poured water in it. Hearing how the plant began to hum as soon as it felt contact she smiled. She crushed the red rock and sprinkled the dust all over the plant She say the plant turn into a blue color. Picking up her wand she said "nox" and sat down in her chair. She wrote down notes quickly and contiuned to keep track of her observations.

Kali began by adding a bit more water first to her plant. It began to hum (finally), but the color remained the same. She then added just a sprinkel of the red dust to her plant. It slowly changed to a yellow-greenish color. She then added a bit of the iron-nutrient to her particular plant and it then bared a more distinct yellow color. Last she casted Lumos onto the plant for about 10 seconds then extinguished it. The plant's final color was a yellow color with bits of red here and there. It also hummed more loudly than when it first started to.

Kali quickly write down her observations on her parchment and raised her hand, "Professor, what exactly type of reaction are we aiming at?"

Raven looked around the room and looked at her watch. Raven looked at her plants which had now changed from yellow to blue to red. "Professor are the supposed to do that?"

Raven smiled. "Maybe emotions? Like when it is blue it could mean sad. Or when it is yellow, happy and entergetic. Or when it is red it could mean mad or disapproving of something?" She hoped she was right. Usually colors talks about emotions. Raven had raised her hand quickly and remember the rule.

Ravens hand was still up but she did manage to put it down to say something else. "Or maybe the plant reflects your mood, your refering to the person that is holding the plant," she said calmly looking at the professor with widdened eyes.

Kali nodded and said to Raven, "Yeah. That would be the logical thing. Colors signifying emotions."

She then thought for a moment and raised her hand, "Or maybe," she said eyeing her plant,"Since this plant's main color of the moment is yellow. Since yellow is the color of the raw berries, maybe the plant is saying that the berries are ready to pick for the yellow dye that they contain?"

Raven looked at Mithos and shook her head. "Just like a guy," she thought and turned back towards the front of the classroom. Professor Virohsa hadn't answered her about her pathetic guess but it was a thought. She merely took the notes that was left on the board while copying down the sketch of the plant.

Sarah looked at her plant for a moment as it hummed softly. She mixed some of the red dust with her water and poured it over her plant and observed it as it's leaves changed to a light blue colour. She added two rocks to the plant and watched as the leaves changed again and faded to a plain white colour.
She took down some notes on the plants changing colours and drew a quick sketch at the bottom of her page.

Raven nodded and looked at Mithos. She had earned 5 points to cover for him but her needed to be more careful himself. She looked at the list and decided to try a combo of red dust, water and light.

Raven looked at Mithos and laughed. "Men, they always complain about the most simplist things," she though soon realizing that her plant had turned a purple shade when she added red dust, light and water. "Pretty," she said breathlessly and looked around at other people plants.

Raven smile turned into a grin of greed as Professor Virohsa told him off. She wanted to laugh at him but Mithos was a nice guy and instead decided to help him. "Professor(she raised her hand before Virohsa could see), for the people that understand the concept can we partner up and work together?"

Sarah added a larger amount of red dust to her plant, watered it and added three small red rocks and then moved it into the shade. She watched as the plant slowly became a dark shade of purple and started to hum slightly louder.
She gazed at it for a few moments and noted down the plants changes on her parchment and looked around at everyone else's plants.

Water, light, red rocks, red dust...

Arkee tapped her chin. How could she change the amount of light?

"Professor," Arkee said, raising her hand, "Would it be alright if I covered my plant with my cloak to see how it reacts to having no light at all? Is that safe?"

Martha sprinkled water on her plant. It took a whole can of it before it began to hum. A little hesitant, she tried a spec of red dust to see what it would do. To her surprise, it turned a light shade of yellow. Smiling she tried watering it again.
