Physics 1 Lab Activity

What's in the Box?

BHS -> Mr. Stanbrough -> Physics -> About Science -> this page

Purpose:

• to practice making observations.
• to distinguish between an observation and a fact.

---

Discussion:

An observation is something you notice, and science is based on observations. This is certainly easy to say. It turns out, though, that it isn't always easy to make observations!  

---

Procedure:

1. When it is your turn, you will have about 10 seconds to observe the items in the box. After your time is up, return to your seat.
2. In the column (of the data sheet) labeled "My Observations", write down the names (or descriptions) of the objects in the box - at least as many as you can remember. Draw a horizontal line below the last item on your list.
3. Once everyone has an opportunity to observe the contents of the box, compare your list with your lab partner's list.
   • If your lab partner observed something in the box that is not on your list, add it to your list under your horizontal line.
   • If you both observed an object, place a check mark next to its name on your list.
4. Once everyone has had time to compare lists with their partners, compare lists with another lab group. Just as before:
   • If the other group observed something in the box that is not on your list, add it to your list under your horizontal line.
   • If both groups observed an object, place a check mark next to its name on your list.
5. Get together with another pair of lab groups and compare lists as before.

Analysis:

Taking into account both your observations and the observations of your lab partners, in the column labeled "What's in the Box" list the items that you are reasonably sure are in the box.
