How does a glow stick work

What I think now (before we start): I think when you snap a glow stick there is a glass tube that holds another chemical that ignites the chemical that is on the out side of the glass tube.

What I think now (after hearing others’ ideas): Well I know now that there might be a really clear glass tube that holds another chemical that means when it snaps the chemical on the outside of the glass tube that chemical will activate the other chemical.

What I think now (after seeing Miss C cut open the tube): My prediction was right that there was a glass tube in it.

Synthesis is when you start with no knowledge but at the end you understand everything.

Sampling lesson

A sample is a small amount of population that works together to create things together e.g cars.

The reason of taking a sample, is to find something that you want to find out about a certain amount or a culture of people.

An example of sampling irl is to go knocking on doors.

The word population means a group of people or something that is living.

You can tell if you are sampling the right population if the population relates to your topic or question.

We picked a question and we asked the amount of people who actually do the question.
