This two-lesson sequence introduces learners to viruses. It includes: • A 31-slide PowerPoint presentation that includes many visual aids and is thoughtfully animated to allow opportunities for discussions during the lesson. • An interactive note-taking worksheet (double-sided A4 size) customized for the presentation. I find that taking notes in this manner keeps lower-level students engaged while allowing differentiation for higher achievers.

This 45-slide PowerPoint and accompanying Lesson Notes teaches the strength of acids and bases. Learners often have misconceptions related to 'concentration' and 'strength' in reference to acids and bases. One of the aims of this lesson is to correct this misconception. The other main aims are listed below. A worksheet (with answers) to practice pH and pKa calculations is also included. By the end of this lessons, students will: 1) discuss and share their initial conceptions of acid strength. 2) be able to define strong acids and weak acids 3) be able to relate the strength of an acid to the value of its acid dissociation constant, Ka 4) learn to calculate an acid dissociation constant 5) be able to differentiate between concentrated acid and strong acid 6) identify common strong and weak acids and bases in everyday life 7) Calculate the pH of strong acid solutions 8) Calculate the pH of weak acid solutions I hope you find this lesson useful.

* Updated January 2017 * Added a crossword puzzle with answers. This 30-slide presentation revises the following learning objectives: 1) To explain how the Earth spinning explains day and night 2) To know what a leap year is and explain why we need them 3) To explain why the average temperature changes as we go through the year 4) To explain why the length of the day changes as we go through the year 5) To describe difference between stars and planets 6) To describe the phases of the Moon 7) To explain that the apparent movement of the stars is caused by the rotation of the Earth 8) To explain total and partial solar and lunar eclipses 9) To explain the effect the sun and the moon have on tides on earth 10) To describe spring tides and neap tides

This resource includes a 50-slide PowerPoint presentation, scaffolded notes, and a revision many practice worksheets on the topic of PRESSURE and the pressure equation. By the end of these lessons, pupils will know that: 1) pressure exists on surfaces, in air and in liquids. 2) pressure is measured in Pascals (Pa) 3) on surfaces, pressure is calculated by dividing force by area. 4) pressure is smaller when a force is applied over a big area because the pressure is spread out over a big area. 5) pressure is bigger when a force is applied over a small area because the pressure is confined to a small area. 6) atmospheric pressure decreases with height, 7) liquid pressure increases with depth. 8) upthrust effects floating and sinking 9) hydraulics is an application of liquid pressure (qualitative and quantitative) I hope you find this resource useful. Thank you.

This resource pack includes 2 of my most popular resources on TES: Magnetism Parts 1 and 2 A total of 61 interactive and and visually appealing slides are included to help Year 7 or Year 8 pupils learn and understand magnetism. Scaffolded note-taking worksheets for pupils have been customized to be used during the series of lessons. Additional worksheets and assessments are also included. The learning objectives are listed below. By the end of these lessons, learners will: 1) be introduced to the discovery and history of magnets 2) know the elements that have magnetic properties 3) observe how magnets attract or repel each other and attract some materials and not others 4) compare and group together a variety of everyday materials on the basis of whether they are attracted to a magnet, and identify some magnetic materials 5) describe magnets as having 2 poles 6) predict whether 2 magnets will attract or repel each other, depending on which poles are facing 7) know that materials contain groups of spinning electrons called domains 8) know that the domains are aligned in magnetic materials 9) know that the domains of a non-magnetic material are not aligned 10) learn about magnetic fields by plotting with compass, representation by field lines 11) learn about Earth’s magnetism, compass and navigation 12) explore the magnetic fields of permanent and induced magnets, and the Earth’s magnetic field 13) discover that a magnet can be made by stroking a steel bar with the same pole of a permanent magnet from one end to the other end in one direction 14) be able magnetise a needle and use it as a simple compass. 15) discover that when electric current flows through an insulated wire wound around an iron core, the core becomes a magnet 16) be able to build a simple electromagnet 17) explore ways to manipulate a variety of variables to increase the strength of the electromagnet 18) know some uses of electromagnets 19) distinguish between a permanent magnet and an electromagnet 20) learn the components of an electric bell and how an electric bell works Please rate and comment.
