Answer:
water and oil don't mix
they form an emulsion
oil is less dense then water
Explanation:
Since there are no given answers, let's examine all pieces of information we can find here.
After mixing two liquids, Janet shook this mixture. She did it in order to enhance the rate of dissolving. After some time passed, we see that these liquids are separated into two distinct layers, meaning that water and oil do not mix (oil doesn't dissolve in water). This also means that water and oil form an emulsion - an unmixable suspension of two liquids.
Another feature we can observe is that the oil had risen to the top. Denser liquid will always fall down, meaning that oil is less dense then water.
After reading the instructions, we can identify the independent, dependent, and control variables as the following:
1. Independent variable: The two types of fertilizers that will be used.
2. Dependent variable: How fast the plants will grow with each fertilizer.
3. Control variable: The plants that will not have any fertilizer added to them.
- When conducting an experiment such as the one described in the question, we are looking for the relationship between two things.
- In this case, we want to see if and how the fertilizers affect the plants' growth.
- The independent variable is the factor we change in order to affect something. Here, it is the use of fertilizers.
- The dependent variable is the thing affected by the independent variable. Here, it is the plants' growth.
- To make sure that the independent variable is affecting the dependent one, we need a control variable.
- In this case, we would select a few plants to not receive any fertilizer. That way, we can compare the plants and see if the fertilizer is making any difference.
