ISD G7 Science Midterm - 2024 - Lorie Delizo-Osborne | Library

----Please read before starting your midterm. ----
Begin the midterm. When finished, do something quietly (seriously, quietly!!).
Midterm Test-Taking Tips:
*****READ THE ENTIRE QUESTION *********
Read the entire question!!
Read tips (a.) and (b.) from above.
Check your work before submitting.
If you’re not sure, try to eliminate options that you know are wrong (with multiple choice questions).
DON’T leave any questions blank. Always at least try. Leaving questions blank and later saying, “I don’t know” is a bad look. Trust me. The person typing this right now is also the person grading this. Hint hint.
Read tips (a.) and (b.) again. Geeeeeeeeeeeez.

Many moons ago, we did a bottle flipping lab. Remember? Well, I hope so. Tell us what the independent variable, the dependent variable, and at least two controlled variables were from that lab AND WHY. It'd be wise to add a bit of detail to your answers to show us what you really know. Just saying.
