# Filling Up A Car With Other Liquids

🔓 This is an unlocked sample! Byrdseed.TV is open for new memberships through October 1st, 2021. Join today!

### Objective

Students will calculate how much it would cost to fill up a car with liquids of their choosing.

We often complain about gasoline being expensive, but, as this New York Times column points out, compared to other liquids, gasoline is actually cheap!

### Steps

1. Pick a car and find its fuel tank capacity. Calculate the cost of filling that car up with gas in your area.

2. Pick at least three other liquids (get creative!) Calculate the cost per gallon and the total cost of filling up the car with each liquid.
