This document outlines a science lesson plan about Newton's three laws of motion for an 8th grade class. The lesson plan covers key concepts like balanced forces and identifying examples of balanced forces in everyday objects. Students will work in groups to analyze examples, discuss forces acting on objects, and identify balanced forces around their school campus. Formative assessments include having students draw and label examples of balanced forces, and present examples they identified during a campus tour. The goal is for students to understand that an object at rest experiences balanced forces and to be able to describe the properties of forces.

Faults range in length from a few centimetres to many hundreds of kilometres, and displacement likewise may range from less than a centimetre to several hundred kilometres along the fracture surface (the fault plane). In some instances, the movement is distributed over a fault zone composed of many individual faults that occupy a belt hundreds of metres wide. The geographic distribution of faults varies; some large areas have almost none, others are cut by innumerable faults.

Although the angle of inclination of a specific fault plane tends to be relatively uniform, it may differ considerably along its length from place to place. When rocks slip past each other in faulting, the upper or overlying block along the fault plane is called the hanging wall, or headwall; the block below is called the footwall. The fault strike is the direction of the line of intersection between the fault plane and Earth’s surface. The dip of a fault plane is its angle of inclination measured from the horizontal.
Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force.
In Physics, force is defined as:
The push or pull on an object with mass causes it to change its velocity.
Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.

Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

Always be guided by demonstration of learning by the pupils/ students which you can infer from formative assessment
activities. Sustain learning systematically by providing pupils/students with multiple ways to learn new things, practice the
learning, question their learning processes, and draw conclusions about what they learned in relation to their life
experiences and previous knowledge. Indicate the time allotment for each step.
A. Review previous
lesson or presenting
the new lesson
The teacher will show a video on balanced force( stop the video up to balanced force discussion)

B. Establishing a
purpose for the
lesson
What is the video all about?
What are the forces acting on the object?
DAILY LESSON LOG OF S8NS-Ia-2 (Week 2 Day One )
2. In balanced force, are the objects in motion?
C. Presenting
examples/ instances
of the new lesson
1. Group the students into 3, give pictures of the following situations below. Let the students
discuss among themselves the condition of the object at rest. Does this mean that there
are no forces acting on them? So what causes them to stay in place?
2. Group 1 – Hanging pen
3. Group 2 – Book on top of the table
4. Group 3 – A boy standing still on the floor
D. Discussing new
concepts and
practicing new skills
#1
. Let each group select a reporter to discuss the answers on the activity Ask the students the
following questions:
Group 1, Is the pen at rest or in motion? Are there forces acting on the pen? If Yes, draw the
forces. You may use arrows to represent these forces.(The pen is at rest; Yes, refer to the drawing
o Group 2, Is the book at rest or in motion? Are there forces acting on the book? If Yes, draw the
forces acting on the book. Use arrows to represent the forces.
(The book is at rest; Yes, refer to the drawing on page 8,figure 5 of the learner’s manual)
Group 3, What are the forces present on the boy standing still on the floor? Are the forces
equal?(force of gravity, frictional force, and the floor pushes upward on the person;Yes)n page
8,figure 5 of the learner’s manual)
E. Discussing new
concepts and
practicing new skills
#2
The teacher will discuss the different properties of Forces.
Figure 1
To accurately describe the forces acting on an object, it is important to be familiar with the
following terms: magnitude, direction, point of application, line of action. Forces are described in
terms of these properties. Magnitude refers to the size or strength of the force. It is commonly
expressed in newton (N). Consider the diagram in Figure 1 showing a force, represented by the
arrow, acting on a ball. The direction of the arrow indicates the direction of the force while the
length of the arrow represents the relative magnitude of the force. If the force applied on the ball
is doubled, the length of the arrow is increased two times. The line of action is the straight line
passing through the point of application and is parallel to the direction of the force.
3. Figure 2. Force diagram
The diagram in figure 2 shows the force acting on the a)Pen and b)Book. All objects fall down
because gravity pulls on them towards the center of the earth. The pen stays in place because of
another force that acts on it that is supplied by the string referred to as tension force (T). The book
on the other hand, stays at rest because the upward push exerted on it by the table which we refer
to as the normal force (Fn). Both the tension force and the normal force counteract the pull of
gravity (Fg) that acts on the object.
F. Developing mastery (leads
to formative assessment
3)
Group the students into 5, let them give (one) example of balanced force and identify the
forces acting on the object. Draw the example and label the forces acting on the object
using arrows. Use white cartolina (1/4 size) and crayons to color their work.
Criteria: content – 10
Visual impact – 5
15 pts.
G. Finding practical
applications of
concepts and skills in
daily living
“Campus Tour” For 15 minutes, let the students move around the campus. Remind the students to
be careful of hazardous objects during the tour. Let them identify one object that they see that is
on balanced force. Be able to answer the guide questions to be written on student’s journal.
1. Is the object moving? Why or Why not?(No, because the forces acting on the object are
equal in magnitude and in opposite directions and they lie along the same line of action)
2. Are there forces acting on the object? Draw the forces using arrows.(Yes, the drawing
depends on the students encounter of the different objects around the campus)
H. Making
generalizations and
abstractions about
the lesson
1. How are forces described?(Forces are described based on their properties: Magnitude,
direction, point of application, line of action)
2. What does the arrow of force indicate? (It indicates the direction of force)
3. In a balanced force, can the object move? Explain your answer.(No, because the forces
acting on these objects are balanced)
4. I. Evaluating Learning
J. Additional activities
or remediation
“My Trip”. On your way back home, identify at least two objects that you see along the way that is
on balanced force. Be ready for an oral presentation the next meeting.
