3 L.O: To differentiate between complete and incomplete circuits. Circuit An electrical circuit can be complete or incomplete. Only a complete circuit will work. Incomplete Circuit Complete Circuit What are the similarities and differences between the complete and incomplete circuit?

4 L.O: To differentiate between complete and incomplete circuits. Let s learn more! 7Q-r7G9ug

5 L.O. To make systematic observations in electrical circuits. Task Instructions: Complete or Incomplete Circuit? 1.On your activity sheets, you will see pictures of circuits. 2.You will need to first predict if you think the circuit will be complete or incomplete. 3.Next, you will need to take the correct equipment and test to see if your prediction was correct or incorrect. 4.Lastly, you will need to record what you have found out on your activity sheet.

6 L.O. To make systematic observations in electrical circuits. Label the circuits on your worksheet. Using the template and items draw an open and closed circuit. Label the circuit.

18 L.O: To learn what a conductor and an insulator is. Aim I can identify and sort materials into electrical conductors or insulators. Success Criteria I can explain why some materials conduct electricity and why others don t. I can test materials to check if they are conductors or insulators.

19 L.O: To learn what a conductor and an insulator is. Insulators and Conductors There are two types of materials: Insulators do not allow an electric current to flow through them so the circuit will not work. Conductors do allow an electric current to flow through them so the circuit will work.

20 L.O: To learn what a conductor and an insulator is. Parts of a Circuit motor wires bulb battery (cell) crocodile clip

21 L.O: To test if a material is an insulator or a conductor. Materials In your groups look at the materials you have been given and label them. What materials did you have? plastic wool linen cupronickel wood copper Are there any materials you were unsure about? Which ones?

22 L.O: To test if a material is an insulator or a conductor. Testing Materials Before you start to test materials to identify if they are conductors or insulators, first create a complete circuit using the following parts: bulb bulb holder battery (cell) The circuit should look like the one on the right when complete. N.B. check that it works and the bulb lights. If the bulb is dim in this circuit, change either the bulb or the battery. Battery holder 3 wires and crocodile clips

23 L.O: To test if a material is an insulator or a conductor. Testing Materials You will need one additional wire. Connect it to your circuit so it now looks like this: Choose a material and add it to the circuit so it looks like this: If the bulb lights, then the material is an electrical conductor. If the bulb remains unlit, the material is an electrical insulator. N.B. Check that all parts of the circuit are connected properly.

24 L.O: To test if a material is an insulator or a conductor. Testing Materials Record your findings on the Insulators and Conductors Activity Sheet.

25 L.O: To test if a material is an insulator or a conductor. Testing Materials Record your findings on the Insulators and Conductors Activity Sheet. Record your findings on the Insulators and Conductors Activity Sheet and answer the after experiment questions. Complete cutting and sticking activity in your science copy. Record your experiment and results in your science copy. Include labelled diagrams.
