The document discusses respiration and the effects of smoking. It begins by defining aerobic and anaerobic respiration and describing how lactic acid builds up in muscles during exercise. It then explains how respiration works to produce ATP and the role of oxygen. The effects of smoking are outlined, including how carbon monoxide reduces oxygen transport, how tar increases cancer risk, and how smoking can lead to diseases like chronic bronchitis, emphysema and lung cancer. Experiments are described to show that carbon dioxide and heat are byproducts of respiration.
Two types of respiration occur in organisms: internal/cellular respiration and external/ventilation. Internal respiration includes aerobic respiration which breaks down glucose completely with oxygen to release carbon dioxide, water, and energy. It occurs in mitochondria. Anaerobic respiration breaks down glucose partially without oxygen to release ethanol, carbon dioxide, or lactic acid, and less energy. It occurs in the cytoplasm. External respiration is breathing and gaseous exchange. Respiration supplies energy for many cellular processes through ATP. Aerobic respiration is more efficient than anaerobic as it releases more energy.
This document discusses the four major categories of stoichiometric calculations:

Multicellular organisms develop through cell differentiation and organization into higher levels. Cells form tissues, tissues form organs, and organs group into organ systems to carry out specialized functions. This allows organisms like humans to have different cell, tissue and organ types that work interdependently. Unicellular organisms rely only on single cells for all functions, while multicellular organisms gain benefits like larger size, longer life, and specialization through their organized cellular structure.
The first microscopes were invented in the 1600s, allowing Robert Hooke to observe cork cells in 1665 and name them "cells". It took almost 200 years after this to discover that plants and animals are made of cells. The basic unit of structure and function for all living things is the cell. Cells contain organelles that support transport of materials into and out of the cell. Multicellular organisms have specialized tissues, organs, and systems like the circulatory system that transport materials throughout the body.

Thanks to http://www.msnucleus.org/ for the Guide to Identification of Fresh Water Microorganisms. I appended the guide to this worksheet I created.
All living things are composed of cells, which are the basic unit of life. Over time, scientists like Hooke, van Leeuwenhoek, Schleiden, and Schwa nn observed cells and concluded that plants and animals are made up of cells. Finally, Virchow established that all cells come from other pre-existing cells, bringing the modern Cell Theory into focus.
This document is a lesson plan that teaches the difference between observing, inferring, and predicting. The lesson begins by having students define observing as using their senses to gather information. It describes inferring as making explanations or interpretations of observations based on prior knowledge, and predicting as forecasting what will happen in the future based on past experiences. Students then watch a video clip and practice writing observations, inferences, and predictions about it. The lesson concludes by having students summarize the differences between the three skills.
Alvarico\'s Science Class Back to School PresentationJoseph Alvarico
Mr. Alvarico Filipino teaches science in room C-6. He outlines several expectations for student behavior, including being on time, staying seated, using respectful language, engaging in learning, and following directions from teachers. Consequences for not meeting expectations range from warnings to detentions to suspensions. Certain disruptive items will be immediately confiscated, and classroom jobs will be assigned to promote shared responsibility for learning.
The document lists the winners of a science fair held at Oak Grove Middle School broken down by grade level, with the 6th, 7th, and 8th grade winners listed but no names or projects included, and concludes with the one-word title "The Exhibit".

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
