Title
Sugar water versus salt water: What effect did they have on seed germination?
Purpose
The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination.
Background information
Plants need nutrients to survive. These nutrients can include nitrogen, calcium, phosphorus, magnesium, sulphur and iron. The plant absorbs these nutrients through the roots from the soil. These examples aren’t the only things plants need to survive though. They need things like water, sugar, and salt. There are many ways that the plant can get its sugar. Photosynthesis within the leaves and the water intake from the roots. The roots cannot make the sugar, but can take in water that contains …show more content…

Although the plant can become dependant on the sugar in the water, the plant will germinate and grow faster than usual. Salt can have the same effect, although the quantity that is essential to survival is far less. Certain amounts of these can accelerate growth, stop growth, and even kill the plant. That is the purpose of this experiment; to see if the effects of the salt and sugar on the plant being tested.
Hypothesis

If the seeds are watered with sugar water, then the germination and growth will be accelerated
Materials
5 Solo …show more content…

Procedure Step 1: Label each of the five cups as follows: 2 salt, 2 sugar, and 1 control Step 2: Fill each of the cups with 1 ½ cups of soil Step 3: Poke holes in the bottom of the cups (enough so that the water can drain) Step 4: Place 10 seeds in each of the solo cups Step 5: Mix 1 cup of water with 2 tablespoons of sugar Step 6: Pour ½ a cup of water into the two cups labeled “sugar” Step 7: Mix 1 cup of water with 2 tablespoons of salt Step 8: Pour ½ a cup of water into the two cups labeled “salt” Step 9: Pour ½ of regular water into the cup labeled “control” Step 10: Record results for the next week (take pictures, notes, any, form of log)

Summary of Data
There are quite a few trends shown within both the graphs and the pictures. The graph shows that the sugar water accelerated the seed germination greatly. The graphs also showed that none of the seeds that received salt water germinated at all. The pictures showed later on that the seeds who had sugar water actually grew taller than the ones that recieved regular
