science ppt for students that The PowerPoint presentation titled "Stages of Human Growth and Development" is designed to provide a comprehensive overview of the different phases of human life from infancy through late adulthood. It begins with a title slide that captures attention with a collage of diverse individuals at various life stages. The introduction outlines the purpose of the presentation, emphasizing the significance of understanding human development. The subsequent slides systematically explore each stage, starting with Infancy (0-2 Years), where rapid physical growth occurs alongside significant cognitive milestones, such as the development of object permanence. The emotional and social aspects highlight the formation of attachments with caregivers. The presentation progresses into Early Childhood (2-6 Years), focusing on steady growth, language acquisition, and the importance of play in socializing and forming a self-concept. As it moves into Middle Childhood (6-12 Years), it highlights logical thinking development, peer relationships, and the role of education. The adolescent stage (12-18 Years) captures the impactful changes of puberty, identity exploration, and the challenges of peer pressure. Transitioning into Early Adulthood (18-40 Years), the presentation addresses peak physical health, crucial decision-making concerning education and career, and the significance of intimate relationships. It then shifts to Middle Adulthood (40-65 Years), discussing the onset of aging signs, experience-based knowledge, and generativity, the desire to contribute to the next generation. Finally, the presentation concludes with Late Adulthood (65+ Years), emphasizing health maintenance, cognitive functions, and the reflections on life. Each section features relevant visuals and infographics to aid understanding, ensuring clarity and engagement throughout. The presentation wraps up with a conclusion that summarizes the importance of the stages of human growth, inviting discussion and questions from the audience, while maintaining a cohesive design with consistent themes, colors, and fonts. This approach ensures a comprehensive yet engaging exploration of human development As the presentation transitions into Early Childhood (2-6 Years), it emphasizes the importance of imaginative play, which fosters social skills, language development, and self-concept formation. Visual aids, such as pictures of children engaged in cooperative play, enhance the narrative by illustrating these concepts in action. The Middle Childhood (6-12 Years) segment highlights the development of logical thinking and the acquisition of academic skills, noting how peer relationships begin to play a significant role in social development. Emphasis is placed on the cognitive shifts as children move from egocentric perspectives to understanding others’ viewpoints, marking a critical phase in their social development. In discussing Adolescence (12-18 Years), the presentation

1. MIXTURES AND
THEIR
CHARACTERISTICS

2. Lesson Outcomes
1.Defined mixtures;
2.Described how mixtures are formed ;and
3.Classified mixtures as homogeneous and heterogeneous
based on their observable characteristics.

3. Explain:
• A mixture is made up of two or more substances or
materials that put together by physical means .
When marbles ,paperclips ,buttons ,sugar and saw dust are
combined together they form mixtures .

5. In forming mixtures ,no new
substances and or materials
are formed because mixing
materials or substances
together does not change
the physical properties of
substances or materials.

6. All phases of matter can be physically
combined to form mixtures and one
more phases of matter can be
abserved in mixtures.

7. What are the example of mixtures ?Some are listed below:
MIXTURE SUBSTANCES COMBINED PHASES COMBINED NUNBER OF PHASE
OBSERVED
salt and pepper salt and pepper solid and solid two (solid)
oil - vinegar oil and vinegar liquid and liquid two (liquid)
air nitrogen,oxygen,argon,carbon
dioxide other gases
gas and gas one (gas)
sea water salt ,water,gases ,such as
oxygen and carbon dioxide ,
and other impurities
solid ,liquid and gas
one liquid
orange juice from powder
concentrate
juice powder and water solid and liquid two(solid and liquid)
smoke air and burnt debris solid and gas two(solid and gas)
carbonated drinks carbon

sugar

9. The three basic characteristics of mixtures are as follows:
1.The
composition of
the mixture is
variable - The
proportion of it's
components can
change.

10. The three basic characteristics of mixtures are as follows:
2.The components
retain their original
characteristics
- The individual substance
that make up the mixture
do not lose their unique
properties when
combined.

11. The three basic characteristics of mixtures are as follows:
3. The components are
easily separated by
physical methods.- A
mixture is a combination of
two or more substances
that are not chemically
combined, allowing for
separation using methods.

12. Mixtures can be classified as homogeneous and heterogeneous.
Homogeneous mixtures, or
well-mixed mixtures, are those
that appear single phased. The
particle size of the components
is too small to be seen by the
unaided eye and the mixture
appears transparent or clear.

13. Mixtures can be classified as homogeneous and heterogeneous.
Heterogeneous mixtures or
unevenly-mixed mixtures are those
where the particle of one or more
components can still be
differentiated from the rest of the
mixture by the unaided eye. Two or
more phases of matter can be
observed.

14. Homogeneous vs Heterogeneous

15. SEPARATING
MIXTURES

17. There are different ways of separating the components
of mixtures:
1. Manual separation is done to mixtures which
components differ in size.

18. There are different ways of separating the components
of mixtures:
2. Magnetic separation is a process that uses
magnet to separate the magnetic component from a
nonmagnetic one.

19. There are different ways of separating the components
of mixtures:
3. Filtration is a process that can separate
suspended particles from the liquid Water can be
separated from starch to some extent using filtration.

20. There are different ways of separating the components
of mixtures:
3. Filtration is a physical
separation process that
separates solid matter and
fluid from a mixture using a
filter medium that has a
complex structure through
which only the fluid can pass.

21. There are different ways of separating the components
of mixtures:
4. Decantation is a process of separating a mixture
of liquids that differ in density The less dense liquid
usually stays on top.

22. There are different ways of separating the components
of mixtures:
5. Evaporation process is used to separate a solute
that has been dissolved in water.

23. There are different ways of separating the components
of mixtures:
6. Freezing or cooling is a process of separating
mixture used for mixture composed of two liquid
components of different freezing points.
