Tell us which experiment
you want to see.
Whether you’re suggesting an experiment, pointing out an error in our content, or sharing your own lab records, we’d love to hear from you.
We read every message carefully. If you’re suggesting an experiment, tell us the subject and the concepts involved; if you’re reporting an error, include the page link and where exactly it appears.
Reader message board
Tell us which experiment you want to see. Messages only show up after we have read them, and everyone can see them. When several people ask for the same experiment, we write that one first.
Before you write, a few notes
These notes help us help you faster — and let you know what to expect.
Suggesting an experiment
The most useful topic suggestions usually include three things: the subject and grade (say, “8th-grade physics”), the concept or textbook chapter it belongs to (“pressure”, “photosynthesis”), and where you’re stuck — materials that are hard to find, steps that don’t make sense, or a result you got but can’t explain. The experiments we most want to write about are the ones the textbook covers in a single line, yet students consistently can’t get to work or can’t make sense of.
Reporting an error
Please include the page link and the exact spot (a section heading or a few surrounding words), plus a short note on what you believe the correct statement is. Messages about factual errors, wrong data or unsafe steps get priority; once confirmed, we fix the text directly and update the date on the page.
Sharing your own experiments
You’re welcome to send us your experiment notes, photos or improvements. If we use your idea or data, we’ll credit you in the article (under your real name, a nickname, or anonymously — your choice). Please don’t send anything containing real names, schools, home addresses or other personal details about you or anyone else.
Posting on the message board
A message does not appear right away. We read it first, which usually takes 1–2 business days, so there is no need to submit it twice. Two things to watch when you write: leave out real names, schools, classes, phone numbers and social accounts — any display name will do; and leave out links — to report an error on a page, email the link instead. Three messages per person per day. We do not publish advertising, abuse, or anything unrelated to middle school science, and we may take down a published message later. Once a message is public, we may quote it in an article, keeping your display name.
Things we can’t help with
- Homework or exam answers: we write about how experiments work and why — we don’t provide answers to problem sets.
- Dangerous procedures: we will not provide steps for anything involving flammable or explosive materials, strongly corrosive chemicals, or high-voltage electricity — and please never attempt these on your own.
- Buying equipment or brand recommendations: nothing on this site promotes a product; our materials lists only give generic specifications.
Replies and privacy
We usually reply within 1–2 business days; holidays are slower. The email form above goes through your own email client. Our servers store nothing, we see only what you wrote, and we use it only to answer that one message.
The message board has to be public, so your display name, role, subject and text are stored in this site’s database. To stop flooding we also store a salted hash of your IP address; it cannot be turned back into an IP and is cleared after 30 days. The board asks for no email address and no account. To take down a message you posted, email us the display name and roughly what it said. Younger readers should tell a parent or teacher before writing or posting. Details are in the Privacy Policy and Terms of Use.
