\"Ionoids<\/a><\/p>\n

Next month I am helping Mrs. Trusty with an after-school STEM coding class using Scratch<\/a>. \u00a0I have used Scratch in the past, but have never tried to do anything complicated. \u00a0After reviewing the basics, I thought I would try to recreate a classic arcade game. \u00a0I made my own version of Asteroids<\/a>.<\/p>\n

After\u00a0I had the Asteroids game working, I converted it to a game\u00a0that can help a student trying to learn\u00a0ionic charges of elements. \u00a0Typically this subject is covered in the second nine weeks of high school chemistry. \u00a0It is also touched on during freshman physical science.<\/p>\n

The game requires you to shoot an ion with that ion’s charge. \u00a0Cations must be shot with positive bullets and anions must be shot with negative bullets. \u00a0The bullet must match the charge of the ion.<\/p>\n

For instance, sodium is a plus one ion so it can only be eliminated with a plus one bullet. \u00a0Oxygen is a minus two ion and must be hit with a negative two bullet. \u00a0Pressing the 1, 2 or 3 key launches a particle with that numerical charge. \u00a0The space bar toggles the charge between positive and negative.<\/p>\n

See how many of the ionic charges you remember with Ionoids<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
