Ocean Waves: Parts, Motion & Breakers | Grade 6-8 Earth Science
Ocean Waves: Parts, Motion & Breakers | Grade 6-8 Earth Science General Information: This slideshow introduces wave vocabulary (wave, crest, trough, wavelength, wave height, frequency, amplitude) and explains that most ocean waves are caused by wind. It shows how water particles move in circular orbits that diminish with depth and describes what happens as waves approach shore: wavelength decreases, height increases, and the crest outruns the base to form breakers.

Human Evolution | Hominin Evolution PowerPoint (+ FREE guided notes) NEW!
This PowerPoint presentation is for teachers who need a 20-30 minute interactive overview of hominin (changed recently from hominid) evolution. Topics discussed are what makes humans similar and what makes them different from other primates, pieces of evidence scientists use in this line of study (fossils and the molecular clock), major developmental milestones in hominin evolution (bipedalism, increased brain size, decreased jaw size, tool-making), and some of the major transitional species ( A

Stoichiometry: Percent Yield
This NGSS aligned lesson builds on the stoichiometry and limiting and excess reactants concepts. The emphasis of this lesson is on concept development of percent yield. Students will distinguish between actual yield, theoretical yield, and percentage yield. Conceptually, students will understand that the percent yield tells chemists about the efficiency of a reaction. Chemists can then work to improve efficiency in several different ways, and increase percent yield. Students will calculate pe

S3.1 Discontinuities in Ionisation Energy, HL (IBDP Chemistry)
This PowerPoint lesson explains discontinuities in first ionisation energy for IBDP Chemistry HL (first examination 2025), helping students understand deviations from periodic trends. It provides a clear, structured explanation of how these discontinuities give evidence for sublevels and electron pairing. Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous 1+ ions. Across a period, first ionisation energy generally i

S3.1 Metallic and Non-Metallic Continuum (IBDP Chemistry)
This PowerPoint lesson explores the metallic and non-metallic continuum, showing how bonding and oxide behaviour change smoothly across Period 3. Designed for IBDP Chemistry (first assessment 2025), it helps students connect electronegativity, bonding type, and acid–base properties to observable chemical trends. Chemical bonding and element behaviour exist on a spectrum rather than in rigid categories. This lesson develops the idea of a continuum from metallic to ionic to covalent bonding using
