Matter is anything that has mass and occupies space. It exists in three physical states: solid, liquid, and gas. In solids, particles are closely packed together and vibrate in a fixed position. In liquids, particles are farther apart and can move freely, while in gases particles are very far apart and move at very high speeds. Diffusion is the movement of molecules from an area of higher concentration to lower concentration. Whether an object sinks or floats depends on its density compared to the density of the surrounding liquid - less dense objects float while denser objects sink.
1. Measure Density of an irregular solid,liquids.
2. Discuss the concept of floatation based on relative densities of solid and liquid
3. Solve Numerical Problems based on formula of density
4. Compare Density of matter in three states, solid, liquid and gas
5. Make predictions using scientific knowledge and effectively communicating the same.
1.Distinguish the three states of matter in terms of movement of the particles
2.Relate the three states of matter with energy of movement of particles in them
3. Describe the changes of state using kinetic theory

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Thinking of getting a dog? Be aware that breeds like Pit Bulls, Rottweilers, and German Shepherds can be loyal and dangerous. Proper training and socialization are crucial to preventing aggressive behaviors. Ensure safety by understanding their needs and always supervising interactions.

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

2. What is matter ?
• Matter is anything that has mass and
• occupies space.
• Matter has mass because its mass is acted
upon by Earth’s gravity.
• Matter has volume as it occupies space.
• Almost everything around us is matter,
whether it’s living things or non-living
things.
3. Mass Weight
A measure of Definition A measure of the
the amount of (What is it?) gravitational
matter in an force on an
object object.
Always constant, Does it change Depending on
no matter the with location? where the object
location. is in relation to
the earth.
A balance Measured A spring scale.

9. Result: A reading less than 100cm3 is obtained.

Conclusion: The small pebbles occupied

11. BROWNIAN MOVEMENT
In 1827, a Scottish
botanist, Robert
Brown, used a
microscope to
observe some pollen
grains in water. He
found that the pollen
grains were moving
about in the water
haphazardly-
Brownian movement.
12. About eight years later,
Albert Einstein explained
the random motion of
the pollen grains in the
water was caused by tiny
water particles which
were moving in constant
and random motion,
hitting the pollen grains
in different directions.
13. High concentration Low concentration
The tiny particles (atom or molecules) of liquid and
gases move randomly in no fixed direction.
14. DIFFUSION
High concentration Low concentration
Diffusion is the movement of the molecules from
the region of a higher concentration to the region
of a lower concentration.
15. When there is no difference in concentration,
molecules diffuse in all directions at the same rate.
18. Do object of the same volume have
the same mass?
100 cm3 of 100 cm3 of
wooden block granite block
19. For the same volume, a granite block has more
mass than a wooden block. Thus, having higher
density than wood
20. density
The density of a substance is the mass of the
substance per unit volume
Density (kg/m3)= Mass (kg) Choose the
Volume (m3) formula
depending on
Density (g/cm3)= Mass (g) the size of the
Volume (cm3) object!!
21. 1. Find The Mass
Find the mass
of an object by
weighing it on a
balance.
22. 2. Find The Volume
Find the volume
of an object by
measuring the
volume of liquid
displaced from
the beaker
23. 3. Find The Density
Mass of a stone = 500 g
Volume of a stone = 26 cm3
Density (g/cm3) = Mass (g)
Volume (cm3)
= 500g
26cm3
= 19.2 g/cm3
25. Density of
saltwater =
1.025 g/cm3
No. It depends on
the density of the
gas or liquid the
object to its
surrounding
Density of a
watermelon =
0.959 g/cm3
26. BIG BUT FLOATS
A heavy ship floats because it
contains large volume of air,
which has lower density than
the seawater
27. SMALL BUT
SINKS
A small stone
sinks because it is
denser than the
salty seawater.
28. The less dense
LESS DENSE liquid will float
on top
DENSER The denser liquid will
sink to the bottom
