Cells are the basic unit of life. They contain organelles that work together to keep the cell functioning. There are two main types of cells - eukaryotic cells which contain a nucleus and organelles, and prokaryotic cells which do not have a nucleus or organelles. Plant cells contain chloroplasts and a cell wall, while animal cells do not.

DNA is a fantastic molecule. Its storage capacity outpaces today's best technology by lightyears. Show your students how it compares to computers today, teach your students its structure and how it replicates, and enjoy some fun facts along the way. Also, pause to ask yourself "How did DNA become like this?" Another great question to ask is "How do you get DNA without first having DNA?" This is a chicken or egg problem par excellence!
BT corn, insulin - scientists have harnessed DNA from bacteria and humans to make new organisms and products. This is a good slideshow presentation for middle school and high school.
Science is knowledge through observation and experimentation. It is facts of principles gained by systematic study. In order to participate in doing science, we must adhere to a "philosophy of science:" There is order to the universe, humans are able to comprehend this order, and scientists should be able to repeat experiments. There are two major kinds of science - empirical science and forensic science. However, science can't answer a lot of questions, and scientists often make mistakes.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. CELL NOTESOrganisms - living creatures. Any life form
that can survive on its own.
Organ systems - made up of organs - work
together to make an organism function.
Example: digestive system
Organs - made up of tissues - work together
to make organ systems function.
Example: stomach made of muscle tissue
and skin tissue
3. Tissues - made up of cells - work together to
make organs function. Example: skin tissue
made up of different kinds of skin cells.
Cells are microscopic - too small to be seen without
a microscope.
Every living thing has at least one cell.
Humans are made of almost 100 trillion cells.
If a single cell can live on its own, it is called a
unicellular organism.
4. Humans are multicellular organisms.
Cell Theory:
1. Every living thing is made up of one or
more cells.
2. The cell is the smallest, most basic unit
of life in all living things.
3. All cells come from existing cells.
5. Prokaryotic Cells
• Cells that do not
have a nucleus
• Another name for
prokaryotic cells is
Bacteria
• ONLY unicellular –
never multicelluar
6. Eukaryotic Cells
• Cells that DO have a
nucleus
• Most eukaryotic cells
belong to multicellular
organisms
• There are some
unicellular eukaryotes
(amoeba, euglena,
paramecium)
