I am doing a crossword puzzle that has statements that you write their answers in the right column. I have two that I can't get.

Heart of a scientific investigation
what I have so far: --e-t--
standard of comparison for checking the results of an experiment
what i have so far: c---r--
Please help I can't figure it out

well, the second one might be control

Thanks! Do you have any idea about the second one?

How about QUESTION for the first one?

Ok thanks I got it now thank you! :)

You're welcome.

For the first statement "Heart of a scientific investigation," you have identified that it is a 7-letter word and you have two letters already filled in as "--e-t--."

To find the answer, you can think about the core element of a scientific investigation. In scientific studies, the central focus is often the thing being studied or observed. It is the main subject or topic that researchers investigate.

Keeping this in mind, the answer to "Heart of a scientific investigation" is likely "Subject." This word fits the pattern you provided: "--e-t--."

Moving on to the second statement, "Standard of comparison for checking the results of an experiment," you have identified that it is a 7-letter word and you have two letters filled in as "c---r--."

To solve this, you can consider the purpose of a standard of comparison in an experiment. In scientific experiments, researchers often use a control group or a known reference point to compare and evaluate the results of their experiment.

Taking this into account, the answer to "Standard of comparison for checking the results of an experiment" is likely "Control." This word also fits the pattern you provided: "c---r--."

So, the answers to your crossword puzzle statements are:
1. Heart of a scientific investigation: Subject
2. Standard of comparison for checking the results of an experiment: Control
