When studying cress seeds, key variables include temperature, light exposure, water availability, soil type, and nutrient levels. These factors can significantly influence germination rates, growth speed, and overall health of the plants. Additionally, variations in seed quality and age can also affect the outcomes of any experiments or observations.
sunlight,water,soil and space.. temperature
Observation-Seeds placed in cotton germinate the same as seeds placed in soil, Hypothesis- Seeds do not need soil for germination Manipulating variables- soil, cotton Responding- height of seeds germinated
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
Variables can be classified into several types: Independent Variables: These are variables that are manipulated or controlled in an experiment to test their effect on dependent variables. Dependent Variables: These variables are measured or observed in response to changes in independent variables, reflecting the outcomes of the experiment. Control Variables: These are constants that are kept the same throughout an experiment to ensure that any changes in the dependent variable are solely due to the independent variable. Categorical Variables: These variables represent distinct groups or categories (e.g., gender, color) and can be nominal (no natural order) or ordinal (with a defined order).
Sunlight signals for germination of cress seeds
Variables: Independent variable: amount of water given to the seeds Dependent variable: length of time taken for seeds to germinate Controls: Temperature of the environment Light exposure Seed quality Soil type and composition
Just put the cress seeds in water and it'll work in days
Garden cress seeds
Cress seeds can be dispersed by being carried by the wind, water, animals, or humans. The seeds are small and lightweight, making them easily transportable to new locations for germination and growth.

Cress seeds come from the Lepidium sativum plant, which is a member of the mustard family. The seeds are small and round, and are commonly used for sprouting or as a salad ingredient due to their peppery flavor.
you can pot dem by putting cottenwool and tissuepaper (toilet paper) in a plastic container then sprinkle in the seeds.
