| Research Question | How does the amount of salt in the water affect the rate of germination? |
| Predictions | If we add more salt to the plant´s water, then it will take longer to germinate. |
| Experimental Design | 1. Take 8 pieces of paper towel and split them into four equal groups of two 2. Fold each of the groups in half 3. Take your 4 plastic bags and put the folded paper towel inside 4. Put 10 nasturtium seeds in each of the four plastic bags 5. Get four beakers, measure 200 ml of water for each of them 6. Keep one beaker with no salt and label it “No Salt” 7. Take half a teaspoon of salt, put it in a different beaker, and label it “1⁄2 tbsp of Salt 8. Take one teaspoon of salt, put it in the third beaker, and label it “1 tbsp of Salt” 9. Take the fourth beaker, put two teaspoons of salt in it, and label it “2 tbsp of Salt” 10. Use a dropper to put 20 equal drops of water from the beaker with no salt in the first bag and label it “No Salt” 11. Repeat with beakers and bags 2-4, make sure to label each bag based on the amount of salt in the water 12. Observe and count the amount of seeds that germinate over five days |
| Conclusion | Claim: The less amount of salt added to the water and given to the seed the faster they germinate and have a higher chance to germinate. Evidence: The seeds with no salt in the water germinated on the second day and 8 of them germinated and the seeds with 2 tbsp of salt in the water germinated on the second day and only 2 germinated Reasoning: This is because salt cant travel through cell was and pass of its own nutrients and some of the water's nutrients and just the water in general because salt absorbs it. |
