Follow this order to complete the activities:
- Activities 0, 1 and 2 from Learning Apps (at the bottom of the page)
- Activity 3 from this web
- Activity 4 from Learning Apps (at the bottom of the page)
- Activity 5 from this web
Activity 0. Electric components (revision)
Activity 1. Electric magnitudes: current, voltage and resistance
Activity 2. Electric circuits: components (paper activity 8)
Activity 3. Electric circuits: how they work (paper activity 8)
Now you are going to build the electric circuit above (activity 1) using an on-line simulator (PhET) .
- Have a look at the pictures below.
- This is very important. Click on Lab and place a lamp on the right top of the work area. Select the lamp and change its value (the resistance) at the bottom of the simulator. The new resistance is the number of your user name for Learning Apps. For example, if you are tpr2m_16, the resistance is 16 ohms.
- Show conventional current, labels and values.
- Now drag the components (a switch, a lamp and a battery) on to the work area; then use wires to connect these components. Don't change any value. Call the teacher to check your circuit. This exercise continues below the pictures.
- When finished, click on PHTE (at the right bottom of the page) and take a screenshot (Circuit Construction Kit_DC screenshot.png) and download your picture to Descargas and then upload it to your Classroom/unit4_1/ICT_Revision.
- Now answer the questions (next activity: part 3) about how this circuit works.
Activity 4. Electric circuits: understanding electricity (paper activity 8)
Activity 5. Series Circuits 1 (paper activity 11)
Draw the circuit below (pay attention to the different values):
- This is very important. Click on Lab and place a lamp on the right top of the work area. Select the lamp and change its value (the resistance) at the bottom of the simulator. The new resistance is the number of your user name for Learning Apps. For example, if you are tpr2m_16, the resistance is 16 ohms.
- To change the value of each component (resistance or voltage), select the component and change the value at the bottom of the simulator. The 2.5-Ω lamp represents the motor in the circuit on paper.
- To measure the current through the circuit place an ammeter in between.
- To measure the voltage drop across 0.5-Ω lamp place a voltmeter touching the terminals of the resistor.
- Check how the voltage is shared in a series circuit (voltage drop across the resistor, the lamp and the motor ).
- When finished, click on PHTE (at the right bottom of the page) and take a screenshot (Circuit Construction Kit_DC screenshot.png) and download your picture to Descargas and then upload it to your Classroom/Unit4/ICT_Revision.
- Extra. Now download the activity in paper. Go to PDF Bob, upload the activity and:
- First complete activities 9 and 10: creating the series, parallel and compound circuits.
- Answer the questions you have in the PDF file (Series Circuit1: measurements with the voltmeter and the ammeter).
- When finished, export your PDF file and upload it to your Classroom/unit4_1/ICT_Revision. Don forget the sticky note, name and surnames...
