The link below takes you to two very useful demonstrations to illustrate Inertial which follow the Predict, Explain, Observe, Explain (PEOE) format.
It is suggested that both demos are performed before introducing Newton’s First Law of motion.

Here’s a twist on the classic chemical hand warmers you can buy for you to research and improve.
If you’ve been outdoors when it’s really cold, there’s a good chance you’ve either used these yourself or wished you had. You can experience a variation on the science found inside a commercial warmer with some pretty basic materials. You’ll discover how an everyday chemical reaction like rusting is used to keep your digits toasty. This experimental version of the hand warmer is offered as a test idea and not as a definitive solution. You’re encouraged to share your science fair results online.

Mars InSight will be the first to detect seismic activity on Mars’ surface, first to measure rate of heat transmitted from interior, first to dig nearly 5m down, first to measure magnetic fields on Mars’ surface, and first to use a robotic arm to place instruments on the surface of Mars (assuming it lands of course…) Continue reading
The 358-kilogram InSight probe is the eighth spacecraft to successfully land on Mars without apparent mishap, but it is not yet certain whether it will be able to fulfill its mission to study the planet’s deep interior
