NOT ANOTHER PLASTIC BOTTLE

In obedience to the “Zero Plastic Program of Bagong Lucena”, LDNHS-YES-O will continue to avoid the use of plastics and other related disposable plastic materials inside the campus. The students will begin using reusable liquid containers as a solution to eliminate the use of disposable plastics. There should be a decline in the quantity of plastic materials being disposed by the school population.

Here below were the proposed sticker design...

MATTER: The Investigatory Processes

Fair Testing 
- Changing only one factor at a time while keeping all other conditions the same.
- The changing factors in an experiment is called variables.


Components of an Investigation

• research problem
• hypothesis
• method for testing hypothesis
• identifying independent / dependent variables
•  conclusion based on evidence

High interest and excitement have lead the student to an investigation that reaches far beyond the requirements. Student has read related materials and has used many sources of information for reports and or experiments. The student has used his/her new knowledge when participating in all oral discussions. Student makes connections between past and present, cause-effect relationships, willingness to change beliefs if necessary, and results in the ability to make a prediction. The students notes, labs, debates and assignments	Strong Student presents a clear, specific understanding of the topic. High interest and excitement leads the student to an investigation that reaches beyond requirements.

Capable Student meets assignment expectations. The student demonstrates new knowledge learned in oral participation and or written tasks. The work is well organized and complete. The student understood the assignments. He/she used the number of resources required; and organized information in all notes, assignments, debates and labs. All notes, assignments and labs are complete, carefully done and the student meets the requirements and expectations. All tests meet the standard level of achievement.	Developing Student knowledge of the topic is partly understood, but not complete. The assignments, notes and labs are occasionally incomplete and could be organized better . Some resources have been used, but it is not clear what the student understood. Some of the information included by the student was not important to the topic Student does most what is required, but nothing more. Some of the work may not be finished. Tasks are not carefully done and the information from the resources is not used. Test results often fall below the standard level of achievement.	Limited Student use of the topic is not shown. Steps through the process were not followed. Notes, assignments and labs lack neatness, organization, detail and evidence of new knowledge. Work does not meet requirements. Parts are missing. Participation is weak, or student is often not participating. Labs, tests and assignments are poorly done and fall well behind the standard level of achievement.
