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.

Investigating Mystery Powders

5th Grade · 45 min · Physical Science

Question

Which of 4 white powders is baking soda?

Safety

Goggles required. Do not taste any powder. Vinegar fumes, ventilate.

Procedure

  1. Add a spoonful of each powder to a separate cup.
  2. Drop 5 drops of vinegar into each cup.
  3. Observe and record reactions.
  4. 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.
