How do you test a hypothesis in science?
Here’s our sample hypothesis: Plants grow more quickly when fertilizer is used than when it’s not used. You can start to test your hypothesis by getting two, near identical plants and growing one with fertilizer and one without fertilizer, but you’ll also have to make sure the test is reproducible and can provide the necessary data.
Why is it customary to make hypothesis before alternative hypothesis?
There is no difference in the speed of plant growth when plants are grown with or without fertilizer. It’s customary to make this hypothesis before the alternative hypothesis, because it allows for a lot less ambiguity in the researchers expected results.
How does temperature affect the growth of plants?
Earlier studies have shown that the protein PIF4 directly controls plant growth and that this protein is also dependent on temperature. When it’s cold, PIF4 is less active—in other words the plant doesn’t grow. At higher temperatures, PIF4 activates growth-promoting genes and the plant grows taller.
What should the Alpha be to write a hypothesis?
Set alpha = .05. Let’s focus on writing hypotheses, rather than any other steps we have learned for now. In order to write the research hypothesis look at what the researcher is trying to prove. Here we are trying to show that the genetically altered plant grows at a faster rate than unaltered plants.

You can start to test your hypothesis by getting two, near identical plants and growing one with fertilizer and one without fertilizer, but you’ll also have to make sure the test is reproducible and can provide the necessary data.
How to grow crops in a dry climate?
Plant shade loving crops in-between larger plants, trees or shrubs. Shade nets can offer relief to newly planted seedlings or plants. When water is scarce, space your plants as close together as possible.

Why is it important to check hardiness of plants?
So whether it’s extreme heat or cold, temperature does affect plants and their growth. This is one of the reasons why it’s important to check a plant’s hardiness and see if it is compatible to your particular growing zone.
