Electromagnet - Coil Turns vs Magnetic Strength STEM Investigation
Students will investigate electromagnetism by building their own classroom-made electromagnets and testing how changing the number of wire coils affects magnetic strength. Using an iron nail, insulated wire, a battery, and paper clips, students observe how electric current creates a magnetic field and how increasing coils strengthens that field. Through repeated trials, data collection, averaging, graphing, and a CER, students discover the relationship between coil turns and magnetic force whi

Newton 1st Law of Motion STEM Investigation | Penny and Index Card Inertia Test
Students will investigate Newton’s First Law of Motion by testing how different masses behave when the support beneath them is removed rapidly. Using an index card, a coin, and a cup, students flick the card to observe whether objects of varying mass drop straight into the cup or move with the card. Through repeated trials, data recording, percent-success calculations, class graphing, and a CER, students learn how inertia affects motion and why mass influences the likelihood of movement. Learni
