Each lesson in teaching order: its one-line summary, the article, the script and the quiz, then your ruling.
Topic 5 · Lesson 1 · Video / article words: 149 / 383 · Quiz items: 10 · Figures: 7
Lesson 1 Chemical energy is stored energy
A battery, food and fuel have chemical energy; in the drawer it is stored; with the switch on, electricity carries it out and it is being released; a fuel's is stored until it burns; a stretched rubber band's stored energy is elastic, not chemical
Topic 5 · Lesson 2 · Video / article words: 145 / 378 · Quiz items: 10 · Figures: 8
Lesson 2 Where a battery's stored energy ends up
The same two batteries in a fan (kinetic energy in the moving air), a flashlight (light out, a warm bulb), a hand warmer (thermal energy in the pack); a camp stove's fuel (thermal energy in the water); the battery stores, the electricity only carries; look at what the device does to predict
Topic 5 · Lesson 3 · Video / article words: 145 / 365 · Quiz items: 10 (one order item) · Figures: 6
Lesson 3 Trace the energy, step by step
Step 1 the energy source and its type of energy; step 2 the carrier; step 3 where the energy ends up — on the train, a gas stove, a reading lamp with two carriers; Grade 4's energy source / receiver / carrier sentences recalled word for word
Topic 5 · Lesson 4 · Video / article words: 150 / 362 · Quiz items: 9 · Figures: 5
Lesson 4 Where a dead battery's energy went
Bright at seven, dim at nine, out at ten; some of the energy went out with the light, the rest warmed the bulb, the battery and the air; a dead battery still has energy but no chemical energy left to provide; Flora's "used up" answered; nothing vanished
Topic 5 · Lesson 5 · Video / article words: 147 / 391 · Quiz items: 9 · Figures: 7
Lesson 5 Where the rolling ball's energy went
A fair test on three floors (8, 4, 1 meters); friction acts where the ball and the floor rub; when two things rub together both get warmer; the kinetic energy ended up as thermal energy in the ball, the floor and the air; Esme's "ran out" answered
Topic 5 · Lesson 6 · Video / article words: 145 / 333 · Quiz items: 9 · Figures: 4
Lesson 6 Heavier at the same speed, more energy
A moving object transfers some of its energy to whatever it hits; the farther the box slides, the more energy was transferred; the loaded wagon has more mass, so more kinetic energy; Grade 3's faster-one rule beside the new heavier-one rule; Ezra's "same speed, same energy" answered
