Imagine you're a scientist and you've got a projector in your lab. You're curious about how much energy it uses. You find out that it uses 500 Joules of electricity. But here's the catch, it doesn't convert all of it into light (Radiant energy). Some of it gets wasted as heat (Thermal energy) which is 328 Joules. Now, can you figure out how much energy is converted into light?

• 500 Joules

• 250 Joules

• 172 Joules

• 828 Joules

Hey there, future scientist! Can you tell us a big way in which our fellow scientists track energy in a system? It's a cool trick!

• All of these, of course!

• By using something called Energy Transfer Diagrams to show where energy is going in a system. Sounds fancy, right?

• By carefully measuring the amount of energy they put into the system. Precision is key!

• By carefully measuring the amount of energy that comes out of a system. It's all about balance!

Imagine this fun scenario: A playful dog is pulling his best friend, a skater, on a skateboard. The Energy Transfer Diagram (ETD) for this situation looks like:

Mechanical (1000 Joules, dog pulling) ---------> Thermal (750 Joules) + Sound (50 Joules) + Mechanical (??? Joules)

• 1800 Joules

• 200 Joules

• 300 Joules

• 1000 Joules

Put on your lab coats and goggles, because you're a super scientist for this question! Can you figure out which type of energy is often seen hanging around, not doing much, like it's some kind of "leftover" or "waste" energy?

• Could it be Radiant energy, just chilling out?

• Or is it Thermal energy, feeling a bit too hot to handle?

• Perhaps it's Sound energy, just making noise?

• Or do you think Energy is too precious to be wasted at all?
