The states of matter.
Solid, liquid, and gas are really just three answers to one question: how much are the particles moving? Study Butler builds every state, and every change between them, from that single idea.
Here is what that looks like.
Study Butler will not print the answer. It points at the next step and lets your kid take it.
An example. The butler answers the question with a question.
why does ice melt into water.
think about the particles. what does adding heat do to how much they move.
makes them move more?
right. so when they move enough to slide past each other, what state is that.
Where students get stuck.
The same few mistakes come up again and again. Here is where the butler slows things down.
01Memorizing states without the particle picture
Solid, liquid, gas mean little without how the particles behave. Study Butler ties each state to particle motion, so changes between them make sense.
02Confusing melting and evaporating
Both add energy, but they are different transitions between different states. The butler has your kid name the start and end state for each.
03Thinking gas is weightless
Gas particles still have mass, just spread far apart. Study Butler surfaces that with a question rather than letting it slide by.
Bring the problem they're stuck on.
Type it, say it, or snap a photo. Study Butler walks your kid to the answer one question at a time, so they learn it instead of copying it.
