  1. Science Notebook • Title – Microworld • Table of Contents: Page – Activity -Date

  2. What I Know About Magnifiers What I Would Like to Find Out About Magnifiers. Notebook- KWL

  3. OBSERVING A PENNY Materials: For Each Participant • Activity Sheet 1 • Penny • Hand Lens

  4. OPTIONAL ACTIVITY • 1 small bottle of vinegar • 1 small container of salt • Paper towels • Wax paper

  5. Notebook Study • What are some characteristics found here that you would probably find on other coins? • What E-Pluribus Unum mean, and what language is it? • Why did you use the magnifying glass on the penny? • How was the smaller magnifier differ from the larger magnifier?

  6. COMMUNICATING YOUR OBSERVATIONS Materials: • Activity sheet 2 • Hands lens For Each Team: • 1 set of objects (screen wire, yarn, burlap,pencil shavings)

  7. “Peanut Babies” • Give each student peanut –Can’t write on the peanut • Write a description of their peanut baby- Include: weigh-measure circumference-length or any other observable feature. • Take the peanut back up: Staying in the nursery • Kidnap the peanut • Students can write an ad for the newspaper describing their peanut. • Reappear – claim their baby

  8. LEARNING ABOUT LENSES Materials: • Hand lens • Activity sheet 3 For Each Team: • Water-dropper • 4 – pieces of waxed paper (about 3 – inches square) • 2 – transparent acrylic cubes • 2 – transparent acrylic spheres • 2 – transparent acrylic cylinders • 4 pieces of newspaper (3 – inches square)

  9. Expository Writing • If you were at home and you had to see an object up close and you did not have a magnifying lens, what could you use to see up close? • Or Explain how you would make a magnifier in an emergency.

  10. LOOKING THROUGH LENSES Materials: • Activity sheet 4 • Marble • Hand lens For Each Team: • Set of transparent acrylic shapes • Water-dropper bottle • 4 pieces of waxed paper • Set of objects from Lesson 2 (screen wire, burlap yarn pencil shavings)

  11. Notebook: Study Questions • Why doesn’t a flat lens magnify? • Do items magnify if they are rounded? • Why did the cylinder magnify the word on it’s side, but not vertically?

  12. Materials: Microscope Microfiche 2 – Slides Reading Activity: Who Invented the Microscope? Student Activity Book: Page 11-12 LEARNING TO USE THE MICROSCOPE

  13. PRACTICING WITH THE MICROSCOPE Materials: • Microscope • Screen wire • Tape • Black and white photographs from newspaper • Black and white photographs from glossy magazines • Colored pictures from newspapers (Comics) • Colored pictures from glossy magazines

  14. Materials: Microscope Activity Sheet 5 Hair (Their Own!) Microfiche Flat Slide For Each Team: Set of objects from Lesson 2 (yarn, burlap, screen, pencil shavings) Water –dropper bottle Pieces of newspaper THE FIELD OF VIEW For Teacher Demonstration: Rigid ring at least 2 ½ inches in diameter

  15. Materials: Microscope 2-flat slides Well slide Cover slip Hair (Their Own) Lens paper For Each Team: Water-dropper bottle Forceps Feather Sponge Poppy seeds Fish scales PREPARING SLIDES For the Class: 1 –2 containers of clear rinse water and paper towels

  16. Materials: Microscope Well slide Cover slip For Each Team: Table salt Epsom salt Quartz sand Tape Lens paper WHAT IS IT?

  17. Materials: Microscope Well slide 2 - Flat slides 2 – Cover slips Optional Activity: Index card with hole punched in center For Each Team: Water-dropper bottle Forceps Hand lens 4 pieces of lens paper Tape EXPLORING COMMON OBJECTS For the class: an assortment of objects, 1-2 containers of clean rinse water, and paper towels

  18. EXPLORING COMMON OBJECTS Reading Selection: Taking a Look with Robert Hooke Student Activity Book (Page 35)

  19. PREPARE HAY INFUSION“IT’S A STINKY JOB, BUT SOMEONE HAS TO DO IT” • Fill several jars one-third full of plant matter of your choice (hay, dried grass, fresh grass). • Add water to the top of the jar. River, stream, pond, swamp, bog, or aquarium water works best. • Cover

  20. Materials: Activity Sheet 6 Microscope Hand lens Slide Coverslip For Each Team: Small onion Water-dropper bottle Scissors Forceps Toothpicks Paper Towel LOOKING INSIDE AN ONION For the teacher: paring knife , cutting board, and a Container of clear rinse water

  21. CELL CAKES • Have parents bake one round cake and one square cake for each group • Students create a 3-D representation of the the animal cell on the round cake and the plant cell on the square cake using icing and candy • Each component is identified and labeled with a toothpick marker

  22. CELL CAKE ASSESSMENT (Layered Look Book) • Name each component of the cell • Identify cell component with its representation on the cake • Explain the function of each component of the cake • In Marie Antoinette's famous words, “Let them eat cake!”

  23. Materials: Microscope “Very” clean well slide Lens paper Coverslip For The Class: Volvox Culture Clean dropper Container of clear rinse water for cleaning slides LOOKING AT LIVING THINGS: VOLVOX

  24. VOLVOX • Found in ponds • Group of organisms known as Green Algae • Uses process of photosynthesis • Live in colonies of 1,000 – 3,000 in hollow spheres held together by clear jellylike substance. • Each cell has two flagella • Smaller daughter colonies are visible inside sphere • Daughter colonies released through opening in parent colony • Rich bright green color the rotates slowly

  25. Materials: Microscope “Very” clean well slide Lens paper Coverslip For The Class: Blepharisma culture Clean dropper Container of clear rinse water for cleaning slides LOOKING AT LIVING THINGS: BLEPHARISMALESSON 13

  26. BLEPHARISMA • Member of ciliates: body covered with short, moveable, hairlike extensions called cilia that move it through the water and force food into its mouthlike opening • Binary Fission: reproduces by dividing itself in half

  27. Materials: Microscope “Very” clean flat slide Piece of lens paper coverslip For The Class: Vinegar eel culture Droppers Container of clear rinse water for cleaning Cotton balls Unflavored gelatin Paper towels LOOKING AT LIVING THINGS: VINEGAR EELS

  28. “WILD THINGS”VINEGAR EELS • Harmless roundworm • Nearly transparent • One of the lowest animals to have a digestive track • Embryos develop inside the female’s body and are born “Alive and Wiggling” • Spends its entire life in unpasteurized vinegar

  29. Materials: Microscope Well slide Flat slide 2 – coverslips Lens paper For The Class: Hay and grass infusions Droppers Container of clear rinse water Cotton balls Unflavored gelatin Paper Towels HAY AND GRASS INFUSION

  30. HAY AND GRASS INFUSION • SAFETY REMINDER: Students should avoid putting hands near eyes or mouths when handling infusions. Have students wash their hands to remove any bacteria.

  31. HAY AND GRASS INFUSION • Hay and grass have begun to decompose • Bacteria on the hay, grass, or your hands began the process • Single celled organisms appeared and fed on bacteria • Organisms had been in a resting state on or in the hay and grass • When the organisms were introduced to water they came out of their protective coverings
