Daydream Education's posters boost student engagement and are great learning and teaching tools for students of all ages and abilities.

Seismic waves are waves that travel through or over Earth. They are usually generated by movements of the Earth's tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides. They can tell us much about the Earth's structure.

Amendments to the Sound information – added info when sound travels from less dense (air) to denser medium (water or solid)

Sound has both volume and pitch. Volume is seen as an increase in amplitude of the sound wave. Pitch is seen as a change in the frequency of the sound wave.

Students learn about the scientific and mathematical concepts around electromagnetic light properties that enable the engineering of sunglasses for eye protection. They compare and contrast tinted and polarized lenses as well as learn about light intensity and how different mediums reduce the intensities of various electromagnetic radiation wavelengths. Through a PowerPoint® presentation, students learn about light polarization, transmission, reflection, intensity, attenuation, and Malus’…

Seeing, hearing, feeling warmth, surfing, tuning the radio, using a cellphone – these and many more activities involve waves. But what is a wave? In this article, we get to grips with the different kinds of waves and look at the key characteristics of all waves – their wavelength, period, frequency, speed and amplitude. These concepts are important for describing waves of all kinds.
