Mulgrave Science

Here you can explore the physics of the inclined plane. For the mass M, we show all forces, gravity and normal force, acting on it. As you change the angle, you can see how the components of the forces change.

Excellent video for explaining atomic spectra in relation to astronomy

Do your students fully understand how a plant cell is organized and how it operates? Let them interact with an online model, learning about the nucleus, the endoplasm and cytoskeleton, centrosomes and lysosomes, mitochondrion, chloroplasts, and plant cell anatomy and functions. Key words can be added to student vocabulary for a comprehension test; be sure to have them draw and label their own models as well. /animcell.htm gives the animal cell version.

Several hands-on experiments are logged here, where students can learn about magnetism and electricity by building their own circuits, playing with compasses and magnets, or simply observing the properties of magnetism and recording them on a student worksheet.

Four student activities explore the properties of magnets, with student worksheets included. The exercises target grades one through five.
