1) ASK A QUESTION

What is the best lettuce cultivar for Mrs. Parsons 4th grade class lunch?

---

2) RESEARCH

• There are many different lettuce cultivars
• Different cultivars are used for different things
• Different cultivars have differences in leaf color, size, shape, etc.
• Click here to see more information on the six (6) lettuce cultivars you will be growing.

---

3) HYPOTHESIS

• I predict all lettuce cultivars will / will not grow the same.
• I predict all lettuce cultivars will / will not taste the same.

Briefly explain your thinking:

4) DESIGN EXPERIMENT

• Plant six lettuce cultivars: DATE: October 4, 2016

1. Camino Verde
2. Rio Bravo
3. Ridgeline
4. Green Star
5. Red Zin
6. Tropicana

• All lettuce cultivars were planted in the same size containers (5" diameter, green pots).
• All lettuce cultivars were planted in the same soil (standard greenhouse potting media).
• All lettuce cultivars were given the same fertilizer.
• All lettuce cultivars were watered the same days, time and amount.
• All lettuce cultivars were grown in the greenhouse under the same environmental conditions (light, temperature...).

5) COLLECT DATA

To determine the "best lettuce" we are going to measure four things:

1. Plant height: Tallest would indicate best because it would produce the most leaves for our school lunch.
2. Leaf Quality: The leaves that look the best are the ones we are most likely to eat.
3. Nutrition: We would like the most nutritious lettuce.
4. Taste: We want the lettuce that tastes the best.

Notes:

Plant Growth. How tall are your plants?

Leaf Quality Evaluation:

• 1 = Unacceptable - Leaves brown, shriveled, dying
• 2 = Poor - Leaves have some dead / brown spots
• 3 = Average - Leaves look OK, but are nothing special
• 4 = Good - Leaves appear healthy, good color and no damage
• 5 = Outstanding - Leaves look GREAT! Just looking at these leaves makes you want to eat them!

Taste Evaluation:

• 1 = Terrible - Disgusting! I need to spit this out!
• 2 = Poor - I didn't spit it out, but I don't want to eat it again!
• 3 = Average - Not bad, not great, either
• 4 = Good - I would eat this again (maybe with a little ranch dressing)
• 5 = Outstanding - I LOVE the flavor. I will definitely eat this again!

6) EXPLAIN DATA

So... what does all your hard work tell you? What does it all mean?

Here are a couple of questions to guide your thoughts:
Look back at your hypothesis. Now look at your data.
Does your plant growth data

support your hypothesis about lettuce cultivar growth? Explain why it does or does not.


Does your taste data

support your hypothesis about lettuce cultivar taste? Explain why it does or does not.

Next let's decide which Lettuce cultivar is the best for Mrs. Parsons 4th grade class lunch:

Look carefully at this data summary table. Consider your Height, Quality, Nutrition and Taste data.




Overall, using all the data you have: What is the overall best lettuce cultivar for Mrs. Parsons 4th grade class lunch? Explain why you think that.

We think rio bravo because it really good and ntion
