There’s been a fire. Your job is to figure out where the fire started, and how.
Fire safety is a complex problem without a single answer. Learn how to engineer and design fire safe spaces.
Safe and sustainable cities will depend on lithium-ion batteries to power our modern lives. But what are the costs?
From hoverboards to cell phones, portable electrical power makes life as we know it possible. But it can come with some dangerous possibilities. Let’s investigate, experiment and search for solutions.
This student guide supports students as they interact with a slice of bologna, a button cell battery, and a dropper of saline solution and observe the results over time.
Through the bologna test, we can visualize some forms of energy transfer. You can replicate the bologna test or observe it through the video.
The bologna test is performed with a lithium primary cell, which is not rechargeable. Lithium primary cells are different from lithium-ion cells, which are rechargeable. However, you could expect a similar reaction from a lithium-ion battery.
