Ok. just prepare.

during a snow day, marissa noticed a truck spreading salt all over the road. after the truck went past marissa's house, she put on a coat and stuff and went to the edge of the driveway to make an observation.

apparently i need to marissa come up with an investigative question, and the answer is probably gong right over my head. , .

Now, i might be wrong but, you have to make a hypotosis of possible theories as to what the truck is doing. Then observe what changes were made after the salt was added then the question should be why was the salt added and how it changed the area. I hope this helps!
