1. Horticulture 4/2/15 Thank you in advance for being respectful and on task today. Please go through the notes in this PowerPoint together and teach each other using the utmost respect. Please stand and teach the class your specific part of the lesson with passion and confidence.

2. DUSTIN PLANT OF A DAY

3. MATTHEW & TREVAN Hardiness

4. The USDA classifies plants on their ability to withstand cold weather (hardy) or not. – Plant Hardiness Map: shows average minimum winter temperatures for given areas (TREVAN - Pass out map and answer questions on the next slide in your notes)

5. Hardiness How many plant hardiness zones are across the US? Which plant hardiness zone is Mishicot in. Why would this map come in handy to horticulturalist? (3+ reasons)

6. KIM Heat Tolerance

7. Heat Zones The American Horticultural Society classifies plants on their ability to withstand hot weather. – Plant Heat Zone Map: shows rating of a summer heat calculated based on average days above 86 degrees F (Answer questions on the next slide in your notes based on map)

8. Hardiness How many plant heat zones are across the US? Which plant heat zone is Mishicot in. Why would this map come in handy to horticulturalist? (3+ reasons)

9. ALEX WATER VS LAND AVALIBIABLITY (APPLE)

10. As Alex Demonstrates.. Answer the Following Questions in your notes: _____% of the earth is water _____% of the earth is land – _____% of the earth is uninhabitable, unarable – _____% of the earth is habitable – _____% of the earth is habitable but unarable – _____% of the earth is habitable arable – _____% of the earth is topsoil Why is this demonstration important? (3+ reasons)

11. Treven R WATER – SOULTIONS

12. Define the following in your notes: Water is a UNIVERSAL SOLVENT – most things dissolve in it SOULTIONS are a – uniform mixture of two or more substances – A SOLVENT is present in the greatest amount – A SOLUTE is present in a lesser amount Hypothesize 3+ places in horticulture we will use solutions with H2O?

13. MEGAN HUMIDITY

14. DEFINE EACH IN YOUR NOTES: HUMIDITY – amount of water vapor in the air as compared to the amount of water vapor the air can hold at a certain temperature CONDENSATION – change in matter of a substance to a denser phase DEW – water in the form of droplets appearing in morning or evening due to temperature PRECIPITATION – forms of water that fall from the sky

15. After defining each… 1. Megan leads a discussion in partners then as a class of 3+ examples of where we would see each in horticulture 2. DRAW one example of each in notes next to definition

16. AUSTIN Functions of Water

17. 1. Pass out scratch paper and have partners brainstorm 3+ functions of water 2. Lead a discussion of hypotheses as a class 3. Record 3+ functions from next slide in your notes.

18. Water’s Functions – RECORD TURGOR (rigidity and shape in plant) CELL DIVISION (growth) INTERNAL PRESSURE (growth – ex: root strength) PHOTOSYNTHESIS RESPIRATION TRANSLOCATION ( & dissolving of minerals) TEMPERATURE REGULATION

19. CHRIS & CARTER EXCESS & LACK OF WATER

20. 1. Pass out scratch paper and have partners brainstorm 3+ plant responses to lack/excess of water 2. Lead a discussion of hypotheses as a class 3. Record 3+ functions from next slide in your notes.

21. NICK - LACKING WATER – RECORD Water Stress Wilting (limp plant tissue) Leaf Rolling or Color Change Brittle/Dead Fibrous Roots

22. CARTER- EXCESS WATER – RECORD Reduced Oxygen Levels Root Hair Death Reduced Transpiration and Photosynthesis Rot

23. JEREMIAH Irrigation

24. Play Video and ensure video/sound quality https://www.youtube.com/watc h?v=24LJSJqpYuY https://www.youtube.com/watc h?v=24LJSJqpYuY

25. NICK IRRIGATION - Question & Answer

26. JORDAN LIGHTS

27. Record In Notes: FLUORESCENT Lights: Higher levels of blue wavelengths – Can be placed close to plants/seedlings INCANDESCENT Lights: Give off red and orange wavelengths – Should not be placed too close to plants as they burn hot! DISCUSS: What type of lights do we have in our headhouse?

28. KYLE J. Photoperiods of Plants

29. Record In Notes LONG DAY PLANTS – initiate flowering when the nights are shorter – ex: barley, red clover, oats, spinach, winter wheat SHORT DAY PLANTS – initiate flowering when the nights are longer – ex: chrysanthemum, poinsettia, soybean DAY NEUTRAL PLANTS - do not appear to change due to day length – ex: grapes, peas, tomatoes, corn

31. KYLE M. Weeds

32. Record In Notes…. Weeds effect on plants… – Compete for water, nutrients, light, space – Reduce quality and yield – Can be poisonous – Host insects and diseases – Increase cost

33. Record in Notes… Broadleaf Weeds - dicot plants – Ex: dandelions, ground ivy, plantain Grass Weeds – monocot plants – Ex: crabgrass, quackgrass
