Question

scenario 7: laurie and abby decide to make guacamole dip with chips to bring to sensational six. laurie used a type of avocado called a hass avocado and abby used a type of avocado called a fuerte avocado. laurie and abby both made their guacamole dip the same way except for one thing...abby put lemon juice in hers to give it a tang. when the girls uncovered their dip at the celebration, lauries had turned a brownish green but abbys was still bright green. the girls wondered if adding the lemon juice to abbys guacamole dip had helped it stay a nice bright green. iv: dv: hypothesis: constants: control group: experimental group: what is another variable that laurie and abby could test in this situation in a 2nd experiment?

Explanation:

• IV (Independent Variable): The presence or absence of lemon - juice in the guacamole dip. This is what is being changed between the two dips.
• DV (Dependent Variable): The color of the guacamole dip. It is what is being measured and is affected by the independent variable.
• Hypothesis: If lemon - juice is added to guacamole dip, then it will stay a nice bright green compared to guacamole without lemon - juice.
• Constants: The method of making the guacamole (except for the lemon - juice addition), the occasion (Sensational Six celebration), the time when the dips are uncovered. These are factors that are kept the same in both cases.
• Control group: Laurie's guacamole (without lemon - juice). It serves as a baseline for comparison.
• Experimental group: Abby's guacamole (with lemon - juice). It is the group where the independent variable is applied.
• Another variable to test: The type of avocado (Hass vs Fuerte) could be tested further to see if it affects the browning rate of the guacamole. For example, they could make two batches of guacamole with each type of avocado, both with and without lemon - juice, to isolate the effect of the avocado type on color change.

Answer:

IV: Presence or absence of lemon - juice
DV: Color of the guacamole dip
Hypothesis: If lemon - juice is added to guacamole dip, then it will stay a nice bright green compared to guacamole without lemon - juice
Constants: Method of making guacamole (except lemon - juice addition), occasion, time of uncovering
Control group: Laurie's guacamole (without lemon - juice)
Experimental group: Abby's guacamole (with lemon - juice)
Another variable to test: Type of avocado (Hass vs Fuerte)
