To minimize barriers to entry, we focus on systems that require minimal prep time and use mostly readily available materials. This is one video of many across the high school physics curriculum that aims to prepare teachers to engage their students authentically. =========================== Connect with us on social media! =========================== Linktree: https://linktr.ee/idealizedscienceins...
