A Science Club Dissection Adventure Have you ever heard someone say, “We’re going to dissect a squid,” and thought, “Wait… the same squid we eat for dinner?” That’s exactly how many people react at first. But once we picked […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Have you ever thought, “Using lots of chemicals in science experiments can’t be very good for the environment…”? Fortunately, there’s a clever solution: micro-scale experiments. In this article, we’ll use this eco-friendly approach to explore the neutralization reaction between hydrochloric acid and sodium hydroxide. […]
