  1. Life Science

  2. What is Life Science? • Everything in the world can be put into two categories: • Living things • Ex: Animals. Bacteria, insects • Non-living things • Ex: rocks, water, air

  3. What is Life Science? • Life science is the study of living things • Also known as Biology • Scientists who study living things are called biologists • Some of the fields can be broken down into specialized branches: • Ex: Zoology (study of animals), botany (study of plants)

  4. How Biologists Work • Depending on the field, they may work in different ways, but they share one thing in common: many biologists work in a lab at least part of the time • What might a biologist who studies genetics do? • A microbiologist?

  5. Living Things are Alike • What do all living things have in common?

  6. Cells!

  7. Organize your thoughts! • Create a flow chart with the following information: • Living things have similarities and differences • The similarities include they consist of cells, have life activities, and use/require important chemicals • The differences include the 5 kingdoms

  8. Living things are made of cells • All living things are made of cells • A cell is the basic unit of life • Most living things are made of many cells • Cells are found in all parts of animal • In animals they may up blood, bones, skin, nerves, and muscle • In plants they make up roots, stems, leaves and flowers

  9. Cells • Cells carry out many specialized functions: • Skin cells: cover and protect • Muscle cells: allow for movement • Bone cells: support and protect • Nerve cells: send and receive messages • Blood cells: transport material and fight disease

  10. Increase your vocab! • Another word for living thing is organism • An organism is a complete, individual living thing • It can carry out all basic life activities • Bacteria are the simplest organism that can carry out all basic life activities

  11. Bacteria

  12. Observing cells • Cells come in different sizes • Most cells are so small they are invisible to the unaided eye • In this case, they can only be seen with a microscope • A microscope is an instrument used to magnify small things

  13. Looking at cells • When looking at cells under a microscope, more details can be seen • Size, shape, colors, etc. • Even parts of a cell can be seen • Organelles: stores material , produces energy

  14. Tissues • Groups of cells that are alike and act together to do a certain job are called tissues • Ex: muscle tissue

  15. Organs • A organ is a group of different tissues that work together • Organs are the main working parts of animals and plants • Organs have specific jobs • Even plants have organs • The roots, leave and stems are organs

  16. Comparing plant and animal cells • Complete the Venn Diagram to Outline the similarities and differences of plant and animal cells • We will share the best Venn Diagram to post on our websites. • Use the Office program you feel most comfortable with to complete the activity • Word • PowerPoint • Publisher
