| Explore | We have a garden currently at school where we water the plants, and even harvest them. We just took a test, including information and topics about germination, for instance we learned that a radical forms into a seed, an epicotyl forms into the stem, and a cotyledon forms into the leaves. This project will further enhance our learning about the topic of germination. We like to test the limits of germination to see what a seed can endure. |

| Research Question | We would like to test how seeds react with other liquid other then water. |
| Predictions | We think salt water will not germinate, we think vinegar will cut into the seed coat and possibly help the seed germinate, and we think baking soda will do nothing to the the seed. |
| Experimental Design | LAB PROCEDURE 1) Inquiry Question: a) What will happen to the seeds if they get different liquids rather than regular water? 2) Hypothesis: a) salt water- will not germinate b) vinegar (acid)- this will burn the seed coat, therefore possibly helping the seed grow c) baking soda (base)- absorb in the seed and it will damage the inside, therefore it will not germinate. d) sugar water- the seed will germinate as normal or even quicker. e) Calcium- the seed will germinate like normal or quicker 3) Procedure a) What We Need i) Salt water, vinegar, baking soda, sugar water, pea seeds, petri dishes, wetted paper towel with the selected liquids. b) Procedure i) Create solutions with all liquids- mixed with water. ii) Set out petri dishes with the paper towels. iii) Add solution to the paper towel. iv) Set seeds in dishes. v) Wet daily with solution. c) What data will be collected? i) The timing of germination will be collected Day Tap Water (%) Sugar Water (%) Salt Water (%) Calcium Water (%) Vinegar Baking Soda 1 0 0 0 0 0 0 2 75 90 0 96 0 0 3 94 100 0 100 0 0 4 98 Roots moderate length. 0 Roots long, stems growing up. 0 2.7 5 100 (Stem super long) Stems short. 0 Stems getting big. 0 5.4 Conclusion The calcium made the plant grow the fastest, however, the tap water grew the longest. Our hypothesis was mostly right. 2nd Half of Lab: We will put seeds in soil and water them with tap water, sugar water, and calcium water respectively. We want to know how long these seeds will grow. Questions 1. How will the seeds react in soil? 2. How long will it take to germinate in light? 3. What is the average time for germination in normal/ same conditions? |
| Conclusion | The calcium made the plant grow the fastest, however, the tap water grew the longest. Our hypothesis was mostly right. |
