Science Labs
Labs your students can actually run. Today.
LoomLesson generates complete science investigations: a testable question, materials you probably have, safety notes, step-by-step procedures, data tables, and a Claim-Evidence-Reasoning analysis framework. NGSS-aligned, inquiry-based, and built for a regular class period.

Question
Which of 4 white powders is baking soda?
Safety
Goggles required. Do not taste any powder. Vinegar fumes, ventilate.
Procedure
- Add a spoonful of each powder to a separate cup.
- Drop 5 drops of vinegar into each cup.
- Observe and record reactions.
- Analyze which cup fizzed and why.
Claim-Evidence-Reasoning
Claim + Evidence + Reasoning, the standard scientific argument framework.
The CER framework
Scientific argument, not just data recording
Every lab ends with Claim-Evidence-Reasoning analysis, the framework that builds real scientific thinking instead of just cookie-cutter lab reports.
Claim
A clear statement answering the lab question
Evidence
Specific data from the experiment supporting the claim
Reasoning
The science that explains why the evidence supports the claim
Works with what you have
LoomLesson defaults to materials that work in a typical classroom: vinegar, baking soda, cups, paper, basic balance. No exotic chemicals, no equipment your school doesn't own. Or tell it exactly what you have and it generates labs using only those.
