|Explore||Alfalfa seeds need to be in a certain environment to grow correctly. For example, they grow best in well-drained heavy clay soil. They should also be planted about 1cm deep to give the best results. If you live in a cooler area then its best to plant them during spring but if you live in a warmer...|
|Research Question||How does the type of soil affect the number of leaves an alfalfa seed grows?|
|Predictions||Our prediction is that if we plant Alfalfa seeds in potting soil, Adri, Nash's, And Ellery's dirt, then the Alfalfa seed will grow best in Adri's dirt. We believe this because Alfalfa seeds grow best in soils that have more clay and by looking at all of our dirt we decided that we think Adri's...|
|Experimental Design||Independent Variable ( What we're testing): Type of Dirt Dependent ( What we're measuring): How many leaves the plant grow The constant variables are the amount of water that we use when we water the plant, and how much light the plants get. Alfalfa seed germinates best at soil temperatures...|
|Conclusion||Claim: Alfalfa seeds will grow best in potting soil and Adri's soil Evidence: In the investigation, the graph shows that Adri's soil and the potting soil both have an average of about 6 leaves which is the highest average compared to Ellerys which is 4 leaves and Nash's average is only 1 leaf...|

"This team did an overall nice job. There final storyboard showed thorough research, planning and data analysis. They were consistent in posting and communicating with their mentor!" - Evelyn Gray, Teacher
The team gave the extra mile to present make a graph and make sense of...
These are great data everyone! It is really neat to see how much Nash's soil differed from the other three. It looks like most of the data on the first three groups are similar except for trail 3. Since you only looked at three trials (which were not consistent), can you think of a different way to set up this experiment if you had more time, space, and money?
Ok team, it sure looks like you have data to record and analyze! As you all are thinking about your observations, think about other factors that may impact what you saw. You have different soil types (and defined how they are different), but are there other differences that you did not originally think of? Is there anything else that might explain your results? I am excited to see what you all come up with.
Ok, great job team. Nash, I see your comment that your plants are not growing, so be sure to record those observations. Your plants may emerge soon, or perhaps not at all. If they never emerge, I think you should try to dig out the seeds at the end of the experiment to see if they even germinated.
Thank you! This was a great project!
