Science homework fails in two places: a concept that never clicked, and a problem you cannot set up. Nerdly works on both. Ask about a concept and it explains it at your level with one concrete example, then checks you got it with a question. Paste a problem and it writes down what is given and what is asked, names the principle that connects them, and only then does the math, with units carried through.
What it covers
- Physics. Kinematics, forces, energy and momentum, circuits, waves, with the free-body diagram described in words and the equation chosen before it is used.
- Chemistry. Balancing, stoichiometry, moles and molarity, gas laws, acids and bases, equilibrium, with the reasoning for each conversion.
- Biology. Cells, genetics and Punnett squares, evolution, ecology, body systems, explained with an example and the vocabulary a test will use.
- Earth and environmental science. Plate tectonics, the water and carbon cycles, climate systems, energy and resources.
Set up first, solve second
In Check my work mode you paste the problem and your attempt. It checks the setup before the arithmetic: the wrong equation, the missing conversion, the sign error in the direction. That is where most points are lost, and where a plain answer key teaches nothing. The honor code explains how we expect it to be used.
Try one of these.
