 # Assessment Criteria - Science (Physics) - Year 8

 KS3 Level Waves and their properties Heating and Cooling Contact Forces Magnets and Electromagnets Projected KS4 Grades Compare the two types of waves and explain the similarities and differences between. Draw particle models to help explain why conduction and convection cannot occur in different states of matter. Apply your knowledge of forces to an unfamiliar context such as: the design a rollercoaster cart and explain how the design helps it travel fast. Apply your knowledge to design a new electromagnetic circuit which could be used in an unfamiliar context. Explain you design. 9 5 Explain how the frequency and the amplitude of a wave relates to how much energy is present in the wave. Explain why conduction and convection cannot occur in different states of matter. Correctly drawn a force diagram for each of the  situation with no errors Compare the magnetic fields of a bar magnet, the earth and a straight coil. 8 4 Apply your knowledge and explain why sound cannot travel in space Explain how a convection current in established using keywords Explain forces acting in each example using most relevant scientific terminology Explain what factors affect the strength of an electromagnet 7 3 Explain how a transverse wave is formed Explain in terms of energy how heat is transferred in convection Explain forces acting in each example using some relevant scientific terminology Explain how to make an electromagnet 6 2 Explain how a longitudinal wave is formed Explain in terms of energy how heat is transferred in conduction Describe what the terms accelerate and decelerate mean Describe simply how an electromagnet works 5 1 Draw a diagram each type of wave and label the key parts Describe what convection is Describe whether or not the forces are balanced or unbalanced in force diagram Draw the shape and direction of a magnetic field around a bar magnet 4 WT+ Identify 2 examples of both longitudinal and transverse waves Describe what conduction is Define the terms balanced and unbalanced force Describe what happens when you place two magnets next to each other 3 WT Define the terms oscillation, wavelength, amplitude, frequency Correctly identify where conduction and convection occurs Correctly identified forces involved in a force diagram Name the ends of a magnet and list 3 strongly magnetic materials 2 WT- 1

Each KS3 level can be subdivided into:-

• + (all of the assessment criteria are met)
• full grade (most of the criteria are met) and
•  (some criteria are met)
