Observation • Use your senses to make ari observation about
your environment.
Questions
• Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "If then" wording. It describes what will happen to the dependent variable
when changes are made to the independent variable. For example, "If a plant is fertilized (independent variable).
then it will grow faster (dependent variable)
• Design and plan an experiment
Be sure to identify an independent variable, a dependent variable, and any controls. Remember, controls are factors
which stay the same. In an experiment designed to test the previously stated hypothesis, one control would be to
use the same kind of plant. Write a complete description of your experiment. Include a list of necessary materials. It
is a good idea to follow a step-by-step procedure format. Think of everything you need to do, then write it down in
the order it must be completed. Your description and procedure should be clear enough that another person could
duplicate your experiment exactly.

Ithink it is quantity of plants

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different.  let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones).  now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first.  for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours.  so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia.
