Nine months ago I posted a blog which was the translation of a page of a Japanese text book (here and here). Mary Whitehouse saw it and introduced me to Shinjiro Ogawa – a Japanese science teacher on secondment to Italy. We met at the ASE conference. Shinjiro introduced me to several Japanese colleagues, all of who are working on fascinating projects.
Shinjiro has been very generous sharing Japanese resources – here is a year 6 activity on electromagnets (from: http://happylilac.net ‘Chibi-Musu-Drill’)
You could use Google Translate and a bit of editing to read this, but I’ve done the first page for you (see below)
I hope you enjoy it!
Elementary school 5th Grade Physics
Strength of an Electromagnet (1)
1. The figure on the right shows how the electromagnet is connected to the circuit. Let’s answer the following questions.
(I) Let’s write the names of ① to ③ of the circuit in the brackets.
(2) In addition to the ammeter in the figure, choose the instrument that can measure the strength of the current from the following and write the number.
① Galvanometer ② Voltmeter ( )
(3) In the circuit shown, some of the wires are not connected. Where should you connect the wires? When the wires be connected and the switch is turned on, will the current flow through the circuit? Let’s write a line in the figure.
2 As shown in the figure on the right, make a circuit with electromagnets connected. Change the number of cells and investigate the strength of the electromagnet. Let’s answer the next question.
(I) For the electromagnet A, 12 steel clips were attracted. How many clips are on B? Before you try, choose from the following ① to ③ and then write the actual number.
① 12 clips ② 23 clips ③ 35 clips
