• Physics Paper 1 Required Practicals
• Specific Heat Capacity
• set up joulemeter to power unit and into the heater too
• measure starting temp + mass of metal block on water on a balance
• turn on joulemeter and heater + measure energy transferred on joulemeter
• measure temperature reached + use equation to calculate the specific heat capacity
• repeat and take an average
• Resistance
• set up ammeter in series
• set up voltmeter in parallel with the wire to be tested
• use crocodile clips to attach the wire to be tested into a series circuit
• measure the current + voltage for 10cm, increase length to 20cm
• repeat increasing the length each time + record results in a table
• calculate resistance and take an average
• Resistors in series
• set up series circuits
• measure current + PD across resistor
• calculate resistance using equation
• add another resistor in series + measure current from each
• calculate resistance from each resistor + add them together
• Resistors in parallel
• set up series circuit
• measure current + PD across resistor
• calculate resistance using equation
• add another resistor in parallel + measure the current + voltage next to each resistor
• calculate resistance for each resistor
• measure voltage across cell + current next to cell, calculate resistance of whole circuit
• Electrical components VI Graphs
• set up circuit
• set up ammeter in series + voltmeter in parallel to component
• set variable resistor on it's minimum resistance + measure current + voltage
• increase the variable resistor + measure current + voltage
• record results in table, repeat, take an average
• draw VI graph
• Calculating Density
• measure mass of object
• measure length of all sides + multiply to find volume
• Calculate density using equation
• measure mass + fill displacement can with water
• place measuring cylinder under spout
• attach string to object and put in can, measure the water displaced
• this is the volume of the object  calculate density using equation
• Force and extension of a spring
• set up a spring hanging over a clamp stand, with weights on holder hanging below + ruler
• measure original length of spring
• add a weight + measure extension
• repeat increasing weight each time + record weight added/extension
• repeat and take an average
• draw a graph and line of best fit, use line of best fit to give extension
