3 hole bottle inquiry activity

As I introduce the scientific method one of my favorite activities is the three hole bottle activity. It is a great way for students to practice writing a hypothesis and making observations. To start you, need a 2 liter bottle with three holes drilled into it in a vertical line in the middle of the bottle. In the picture they are behind the tape. They are slightly small than the diameter of a pencil eraser. I have the students set up a chart on the right side of their interactive notebook as seen below. To begin, I take the bottle filled with water and the tape over the holes (as pictured) around the room to each student so they can record as many observations as possible . They record these observations in the first column titled  “cue column” . Next, for dramatic effect and to discuss bias I take one student volunteer to the front of the room and hold the bottle over their head (after I give them paper towel) and ask the class to make a prediction as to what will happen when the tape is pulled past the first hole. They record that in the first column. I then remove the tape from the first hole while holding the bottle above the volunteer student’s head (only a few drops usually comes out of the bottle). Students the record their observation and then make a hypothesis about what will happen when the tape is pulled past the 1 and 2 hole and then all three holes. To finish I turn the bottle on it’s side and have the students share their hypothesis with the class. Students then make a conclusion about their observations and a class discussion about what happened.  On the left side, students were given the option to draw a graphic that explains everything that happened or they can fill the page with a written description (since a picture is worth a thousand words). I offered a homework pass for the most creative left and right side notebook pages with accurate descriptions and properly writing hypotheses.

  1. This comment is not about this post, but about your other pages. I am a first year biology teacher and I had found this page really helpful for ideas for lessons and activities. Recently (late December), I have found that all of the pages except for “Home” are now password protected. Is there any way I could still have access to your awesome ideas? If not, I understand, just wanted to check!

    Thanks for all you do!
