| Explore | Germination- to start growing seeds wait to germinate until the three needs are met: water, goo location, and correct temp. Early stages of growth relies on the stored food in the seed |

| Research Question | Which type of water (salt, sugar, fertilizer, or tap) would make a pea germinate faster? |
| Predictions | If fertilizer is added to water to germinate a pea, then it will germinate the fastest. |
| Experimental Design | 1. Get 4 petri dishes and lay paper towel down on the inside of each of them 2. Put 10 pea seeds into each dish 3. Create 4 different types of water to give the peas. The 4 different types are sugar, salt, fertilizer, and tap water a. Get 4 different bottles of water b. Add either a tbs spoon of sugar, salt, or fertilizer into it. Leave one with just tap water c. Try to mix it the best you can 4. add ______ drops of one solution to their specific petri dish 5. Put under light for _____ hours 6. Repeat this each day until thy germinate |
| Conclusion | Claim: The type of water that made a pea seed germinate the fastest is inconclusive. Evidence: We know this because the sugar seed germinated 3 cm and regular tap water didn’t germinate at all. This would show its inconclusive because tap water wouldn’t make a seed not germinate. Reasoning: We know this would be inconclusive because others groups pea seeds germinated when just water was just added. We think this happened because we didn’t wash the beaker before soaking in the seeds. This might of made our seeds mold, and that’s why we think most of our seeds didn’t fully germinate. Also we could've added too much solution to each petri dish and made our seeds not germinate, but mold. Another outcome during this experiment is our water seeds shriveled up, possibly from the not washing the beaker or the loose lid ( most likely coming from the loose lid). This is why we think our data is inconclusive. |
