Sweet Pea Perfume Delight- Lathyrus Odoratus
1. Flower
2. Annual blooms. Spring/Summer full sun
3. 10-15 days to emerge. Soak seed in water for 12-24 hours or nick with sandpaper before planting.
4. Thin when 3" tall, thin to 6" apart.
5. 2" between each seed. 1" seed depth
6. Do not use garden soil. Use a good quality potting mix. Potting mix recipes are formulated to perform in the conditions present in a small container, where using garden soil can result in problems like compaction and poor drainage. Always pre-moisten your potting mix before filling your container.
7. Sweet peas require a lot of water. Be sure to water germinating seeds, seedlings, and actively growing mature vines regularly. Keep them moist at all times.
8. Grow sweet peas with other cut flower plants or in cottage gardens with heirloom flowers and herbs.
9. Sweet peas have been cultivated since the 17th century and a vast number of cultivars are commercially available.
Lima Beans- Phaseolus limensis
1. Vegetable
2. In Southern California the best time to grow lima beans is from March to August.
3. 6-8 days to germination.
4. 75 days to harvest.
5. Spacing: Row/Plant 2.5 ft - 4in. 1.5 inches deep.
6. Medium-rich, well-drained, deep sandy loam. pH RANGE: 6.5 - 7.5
MOISTURE/WATERING: Average
7. Lima beans need a sunny, warm spot with very well drained soil as lima beans prefer a dry soil and a long, warm growing season.
8. Since beans fix nitrogen in the soil, they are great "helper plants in the garden. They are particularly good with the following vegetables: carrots, beets, broccoli, brussels sprouts, cauliflower, celery, corn, cucumbers, eggplant, kale, peas, potatoes, radishes, strawberries, swiss chard.
9. Raw lima beans contain a cyanide compound and should not be eaten raw. Only those varieties with the lowest cyanide levels are legally allowed to be sold in the United States. Cooking deactivates the cyanide compound.
Dipper Gourd- Lagenaria
1. Vegetable
2. Late fall.
3. sprouts in 10-15 days
4. Matures in 110 days. Harvest in lat fall after plant has died back. Dry in a cool place with good air circulation. Black spots and mold are normal while drying. After a few months, when the seeds rattle inside, your gourd is completely dry.
5. Seed space- 24" Seed depth- 1"
6. Ideally, gourds should be planted in mounds of nutrient rich, well-drained soil with a pH of 5.8-6.2. Space mounds about 4 feet apart with 3-4 seeds to a mound. Mulch around plants to control weeds. Gourds will deplete the soil of nutrients and should not be planted in the same place in consecutive years.
7. Gourds are not drought tolerant. Soil should be kept consistently moist (not wet) and plants should be watered at least once a week during dry periods.
8. Some plants to use with gourds: radishes, catnip, broccoli, tansy, dill, marigolds
9. Lagenaria, or hard-shelled gourds, have been cultivated since prehistoric times for use as storage, drinking vessels, and utensils. Dipper Gourds grow about fifteen inches long-- much longer if trellised. Easy to grow like squash. Great for craft projects.

Carbon Fixation in Elodea- Lab
1. Why does the phenol red change color when we blow bubbles into the tube? Phenol red is an indicator in this experiment. What did it indicate?
The phenol red changes color because when we blow through the straw we are adding CO2 to it causing it to change a yellowish color. It indicated the carbon dioxide that plants need to go through photosynthesis.
2. How long did it take to observe a color change in the phenol red? What does the color change indicate in terms of the Elodea plant?
The phenol red turned yellow after only a couple seconds of me blowing into it with a straw. The color change indicates that there is enough carbon dioxide in the phenol red for the plant to go through photosynthesis.
3. If carbon fixation occurs during the light independent stage of photosynthesis, why did the procedure call for placement of the test tubes under the grow light?
It called for us to place the test tubes under the grow light for the other stages of photosynthesis. We covered one of the tubes with foil to prevent any light for entering to see how that would effect the process.
4. Did you see a change in color of the phenol red test tube with no elodea added? Why or why not?
No, because there was no plant to take in the carbon dioxide in the phenol red.
5. Does carbon fixation occur in humans? Can you think of any other organisms that fix carbon?
No, I believe that carbon fixation only occurs in plants.
6. How does a plant use carbon? What is meant by the term carbon fixation?
Plants can reduce the carbon from carbon dioxide to the carbon in the organic compounds which they depend on. This is called carbon fixation. These organisms may be called primary producers or autotrophs.
7. Identify and explain the control in this experiment. What is the purpose in having a control?
When doing any kind of experiment you want to have a control to compare the results of the final product. The control in this specific lab was the tube with no Elodea plant in it so we could observe what exactly the plant does with the phenol red.
