The cardiovascular system consists of the heart, blood vessels, and blood. The heart pumps blood through arteries, which branch into capillaries where oxygen and nutrients are delivered to cells. The deoxygenated blood then returns to the heart through veins. There are two circulation loops - pulmonary circulation between the heart and lungs, and systemic circulation between the heart and the rest of the body. The cardiovascular system functions to transport oxygen, nutrients, hormones, and waste products throughout the body.

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

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

8. Arteries
• Carry blood away from
the heart.
• Under higher pressure
– smaller tubes.
• Carry oxygenated
blood.
• Surrounded by smooth
muscle.
9.
10. Capillaries
• Tiny tubes
• Run close to every cell in yer body.
• Blood cells have to travel in single file.
• Capillary walls are so thin that oxygen,
CO2 and nutrients can pass through them.
• What’s a bruise?
11.
12.
13.
14.
15. Veins
• Carry blood back to the heart.
• Blood is deoxygenated- it’s carrying CO2
• Lower pressure – larger tubes.
• Veins have one-way valves.
• Contracting muscle squeezes veins,
forcing blood back to heart.
16. Parts of your blood:
• Red Blood Cells (RBCs)
• White Blood Cells (WBCs)
• Platelets
• Plasma
17. RBCs (Red Blood Cells)
• RBCs carry oxygen (O2) AND carbon dioxide
(CO2)
• Each RBC has a protein called hemoglobin,
which binds to the O2 or CO2
• Hemoglobin needs iron to work. If you don’t eat
food with enough iron, you could get dizzy or
faint.
18. RED BLOOD CELLS
Unlike most other cells in the body, red blood cells
have no nuclei. Lacking this large internal structure,
each red blood cell has more room to carry the
oxygen the body needs. But without a nucleus, the
cells cannot divide or synthesize new cellular
components.
After circulating within the body for about 120 days,
a red blood cell will die from aging or damage. But
don't worry — your red bone marrow constantly
manufactures new red blood cells to replace those
that perish - at the rate of 2 million per second!
19. WBCs (White Blood Cells)
• WBCs kill viruses and bacteria
• Pathogens – bacteria, viruses, or other
microscopic particles that make you sick.
• If pathogens enter the body, WBCs will engulf
(swallow) and digest them.
• Other WBCs release Antibodies – tags that
stick to pathogens. CLICK HERE TO SEE
20. Platelets
• Platelets – tiny particles that clot your blood.
This requires a multi step chemical process,
called a cascade.
• If an artery or capillary or vein is broken or
damaged, platelets clump together in the
damaged area, forming a plug that helps save
blood from leaking out.
• Clotting: platelets also release chemicals that
react with proteins in the plasma, starting a
chemical reaction that causes tiny fibers to form
a “net” that stops the bleeding.
21. Plasma
• Plasma – the fluid part of the blood.
• Consists of water, minerals, nutrients, sugars,
proteins and more!
22. The Heart’s Structure
Parts
Atrium - receives the blood that is coming
into the heart. Found at the top of the
heart
Ventricle – pumps the blood out of the
heart. Found at the bottom of the heart
Valve – A flap of tissue that prevents the
blood from moving backwards.
23. How the heart works
First Phase – The heart muscles relax,
blood fills the heart
Second Phase – the heart muscles contract,
the blood is pumped out of the heart
28. Circulation Systems
Pulmonary Circulation
From the heart to the
lungs and back to the
heart
Picks up oxygen, drops
off carbon dioxide
Systemic Circulation
From the heart to the
body and back to the
heart
Drops off oxygen and
picks UP carbon
dioxide
29. Cardiovascular System Functions
Function How?
Carry needed
substances to cells
The blood brings oxygen and
nutrients to the cells
Carry wastes
products away
from cells
The blood takes away carbon
dioxide and other wastes
from cells
Carry disease
fighting cells
White blood cells prevent you
from getting sick by killing
bacteria or other things in the
blood
30. Fun Fact – you’ve got a lot of blood
tubes!
If you were to lay out all of the arteries, capillaries and
veins in one adult, end-to-end, they would stretch
about 60,000 miles (100,000 kilometers). What's more,
the capillaries, which are the smallest of the blood
vessels, would make up about 80 percent of this
length.
By comparison, the circumference of the Earth is
about 25,000 miles (40,000 km). That means a
person's blood vessels could wrap around the planet
approximately 2.5 times!
31. Fun Fact – the bigger the slower
Across the animal kingdom, heart rate is inversely related to
body size: In general, the bigger the animal, the slower its resting
heart rate.
An adult human has an average resting heart rate of about 75
beats per minute, the same rate as an adult sheep.
But a blue whale's heart is about the size of a compact car, and
only beats five times per minute. A shrew, on the other hand, has
a heart rate of about 1,000 beats per minute. Hummingbirds
have a heart rate of 1,260 beats per minute, but their hearts slow
to 50 beats per minute at night when they enter a hibernation
state known as torpor.
32. Fun Fact – your heart doesn’t need
your body to beat!
The heart actually can still beat after
being removed from the body.
This eerie pulsing occurs because the
heart generates its own electrical
impulses, which cause it to beat. As long
as the heart continues to receive oxygen,
it will keep going, even if separated from
the rest of the body.
33. Not so Fun Fact – you can have a
“broken heart.”
A condition called stress cardiomyopathy entails a
sudden, temporary weakening of the muscle of the
heart (the myocardium). This results in symptoms
akin to those of a heart attack, including chest pain,
shortness of breath and arm aches.
The condition is also commonly known as "broken
heart syndrome" because it can be caused by an
emotionally stressful event, such as the death of a
loved one or a divorce, breakup or physical
separation from a loved one.
Editor's Notes
Good question for evolution: How did this system evolve? Which evolved first? The heart – but what would it pump if there wasn’t any blood? The blood – how would it get around if there wasn’t a heart to pump it or tubes to carry it? The blood vessels – why would blood vessels evolve without blood? The whole system has to be in place – all working together. Take out one piece and doesn’t work.
