DWA

1. DWA What are the two types of cells? Describe the two types of cells?

2. Organelles

3. Tues – Aug 15, 2017 • Today’s Lesson: • CELLS • Essential Question: • Where do cells come from? • Opening: • What are Cells • Mini-Lesson: • Comparing Cells • Work Session: • The Organelle Trail • Notetaking – Organelles • Summarizer: • Homework: • PROJECT: • HOMEWORK: Due TODAY

4. Standard – S7L2 Obtain, evaluate, and communicate information to describe how cell structures, cells, tissues, organs, and organ systems interact to maintain the basic needs of organisms.

5. Sort Activity • Complete sort activity. Students are given choices of cells and must figure out how to group them and explain the reason for their grouping. Create a chart with their results of how they sorted the cards. Explain why you put the cards where you did. Write this explanation out.

6. Sort Activity • Should colors be a major factor? • (Some pictures might be a specific color just because they are stained in order for them to be more visible.) • What about size? • Did you consider shape?

7. Sort Activity The different sizes and shapes of cells is our phenomena!

8. PHENOMENA An exceptional fact, event, or circumstance that can be observed AND communicated!

9. Cells • Cells are the basic building blocks of all organisms (living things). • Example: plant and animal cells, some animal cells that we have are red blood cells.

10. Tissues • Tissues are made up of different cells. • The blood that runs through our body is made up of many types of cells and therefore is a tissue. The muscle that makes up our heart is made of many cells and is also a special type of tissue.

11. Organs • Organs are made up of different tissues. • Cardiac tissue, epithelial tissue and other types of tissue make up our heart, veins and arteries which are organs. Some other organs are our lungs, kidneys and eyes.

12. Organ System • Organ systems are made up of different organs. • Our circulatory system is made up of our heart, veins, arteries, etc… and therefore is an organ system. Some other systems are our respiratory, skeletal and digestive systems.

13. Organism • Organisms are made up of many organ systems. • Our body is made up of our circulatory, respiratory, digestive, skeletal and many more system. Therefore, we are organisms!

14. The Characteristics ofLiving Things • Biologists use six characteristics to classify something as a living thing. 1. Made of Cells 2. Use and Need Energy 3. Adapted to Their Surroundings (Respond to stimulus) 4. React to Changes 5. Reproduce 6. Grow and Develop

15. The Characteristics ofLiving Things • All living things have these six characteristics. • Anything without one of these six characteristics is nonliving. • Living things are called organisms.

16. 1. Made of Cells • Organisms are made up of one or more cells. • A cell is the basic unit of structure and function in living things. • Cells = the of life. “Building Blocks"

17. All organisms need and use energy to live. Energy is the ability to do work. Sunlight is the source of energy for most living things. Plants use the energy in sunlight to make food, and animals get energy by eating plants or other animals that have eaten plants. 2. Use and Need Energy

18. 3. Adapted to Their Surroundings • Organisms are adapted, or suited, to their surroundings. • Some break this into 2 categories by saying organisms respond to stimuli also. • All organisms have features that help them survive in their surroundings. • For example: fish have gills

19. 4. React to Changes • Organisms react to change in their surroundings. • Any reaction to change is called a response. • For example: A bright light may cause you to blink.

20. 5. Reproduce • Organisms produce more organisms of their own kind. • Reproduction allows organisms to continue living on the earth.

21. Living things change, or develop, during their lifetimes. One way organisms change is by growing. Living things may also change in appearance. For example: tadpoles and frogs All organisms grow and develop. 6. Grow and Develop

22. Summary • Biologists use six characteristics to classify something as a living thing. 1. Made of Cells 2. Use and Need Energy 3. Adapted to Their Surroundings 4. React to Changes 5. Reproduce 6. Grow and Develop • All living things display all of the above characteristics.

23. Discussion As a teacher, one of the techniques for presenting information to your students is through lecture. However, traditionally lectures have been thought of as dull, boring, and utterly uninteresting. Often students don’t pay attention, and even those who do don’t get much actual learning out of it. That was until now. With the help of Power Point almost any lecture can be spiced up to captivate its intended audience and at the same time convey the information that needs to be conveyed. Using Power Point a teacher can add sounds, pictures, movies, and even Flash programs to any lesson. Trying to incorporate these types of valuable multimedia to the chalkboard is virtually impossible. Thus, in my classroom I can foresee myself using Power Point as a tool to lecture with. I could set up my lectures over the summer or whenever I had the free time and could then present them to my students when that chapter was being covered. I think that Power Point would add some value to my lectures in that the students would be more interested and numerous sources of multimedia could be included. The only drawback I see to using Power Point is that it’s somewhat involved and can take a while to produce. However, the extra time that is spent making a Power Point lecture is not wasted time because the lectures can be used again and again. For my students I can foresee Power Point as a project that they might have to complete. I could apply this idea in a number of ways. For example, when learning about the periodic table each student could be assigned a specific group from the table or a specific element and could then produce a Power Point slide show to describe the properties of that specific group or element. Students could also use Power Point as a way of writing-up one lab that they do during the year. The students could develop a slide show to explain the purpose of the lab, the procedure of the lab, and then their results from the lab. They could then present their slide show to the class. I think both of these ideas provide a good break from the normal monotonous homework, lab write-ups, and tests that a chemistry class entails.
