In learning about density, a measurement of the amount of matter in a given volume of a substance, we have looked at multiple examples of how two substances will either float or sink in relation to each other. The picture below is an example of how mulitple liquids and solids relate to one another in one example.

We are currently practicing using the Scientific Method in order to conduct controlled investigations, meaning that only one thing is changed. Listed below are some of the key things we have been practicing in class and on labs.

1. Writing a scientific question. I have been encouraging students to start their scientific question with, 'What is the relationship between.....?'  This format allows us to easily add the independent variable and dependent variable into the question without changing much.

What is the relationship between how deep a grass seed is planted and how long it takes to sprout above the ground?

The orange phrase represents the independent variable, the one thing that is changed during an experiment. The green phrase represent the dependent variable, the one thing that is measured to see if the independent variable actually does cause a change in results.

2. Writing a hypothesis using the If...then....because.... format.

If I plant grass seeds at varying depths in soil, then the seeds that are planted the deepest will take the longest to sprout above the ground because they will have to grow longer in order to break the surface.

3. Identifying the controlled variables, everything that needs to be kept the same in order to achieve accurate results.

Controlled variables would include: amount of water, type of soil, sunlight, temperature, seed type, planting method, amount of soil, time of watering, watering method, etc.
