Question

alana wants to measure the speed at which drops of precipitation fall to the ground in los angeles. which statement identifies a way alana uses technology to complete her experiment? ⓒ she observes daily rainfall data from multiple weather stations throughout the city. ⓒ she graphs the relationship between rainfall speed and time using graphing paper. ⓒ she analyzes a map to determine different places to collect rainfall for the study. ⓒ she estimates how fast rain falls by studying the sky at different locations in the city.

Explanation:

To determine how Alana uses technology, we analyze each option:

• Option 1: Weather stations are technological tools that collect and store rainfall data. Observing data from them uses technology.
• Option 2: Using graphing paper is a manual method, not technology.
• Option 3: Analyzing a map (even if digital, the act here seems manual) and determining places is not using tech for the experiment's data collection/analysis related to speed measurement.
• Option 4: Estimating by studying the sky is a manual observation, not technology.

Answer:

A. She observes daily rainfall data from multiple weather stations throughout the city.
