Candle Observation


Just wanted to post this quick, last week we completed a candle observation activity.  I broke the activity up into 3 parts: making observations for 5-10 minutes before the candle is lit, 15 minutes for observing the candle as it burned, and about 5-10 minutes after the candle was blown out.  For each set of observations, they had to have one picture, ask 1 or 2 questions, and list 10 or more observations. I also provided rulers so they could take measurements of how tall the candle is, how big the wick was, the width of the candle, etc. For safety reasons, I lit the candles and made sure that the girls tied their hair back with string or a hair tie if they had one. I also placed the candles into beakers since I didn’t have candle holders.

This was a simple activity, but the kids loved it, and it was a great way to review a lot of the skills we learned this year. They were also able to observe physical and chemical changes, and watch the wax melt and “freeze” – I reminded them that changing from a liquid to a solid can happen at any temperature, it depends on the substance you are talking about.

Mystery Footprints


My 5′s completed the Mystery Footprint Activity (ppt) and it went really well! We talked about what an observation is, what an inference is, and how they really have to be careful- they often wanted their inferences to be their observations!

After a brief introduction/ discussion, we filled in their notes. Then I had them close their eyes and I slowly read the three sample observations: I hear people screaming, I see a lot of people around, and I smell cotton candy, popcorn, and hamburgers. When they opened their eyes they wrote down where they pictured themselves-which is their inference. I had students raise their hands to tell me where they were – these are some of their responses:

  • a circus
  • a fair
  • a carnival
  • a theme park
  • on the boardwalk or at the beach
  • at a sporting event

I asked them, “Did we all have the same observations?” And most said no. Then I repeated the observations – people screaming, a lot of people around, smelling cotton candy. Yes, we all had the same observations, BUT our inferences were different. We used our individual experiences to process the information and formed our own conclusions. Ohhhhhh!

I then showed the slides for the Mystery Footprints. Frame 1: One student’s observation was, “I see an animal running”. I said, “I don’t see an animal running, I see tracks that start off close together then become farther apart.” I then explain that I can infer that the animal was running, but I didn’t see it happen, I just see the tracks that are left behind. Some observations are that the background is yellow, there are two sets of prints, the tracks are coming from 2 different directions, the red tracks are close together, etc…

We viewed each frame and discussed our observations and then shared our inferences. When I showed the 3rd frame, a lot of the students gasped, they were so into it and when they saw the red prints missing, they were quickly writing down their observations and inferences!

Some great inferences the kids came up with:

  • the animals were fighting and one ate the other (most common answer)
  • one animal bit the other animal and carried it away to eat it somewhere else
  • the animals were eating food off the ground, one walked away while one stayed behind to eat more
  • the animals fought over the food, and the loser walked away
  • the tracks were made at different times and ate the same food that was on the ground
  • one animal flew away
  • one animal jumped onto the back of the other animal
  • the animals were dancing until one walked away

We went over the homework assignment and I really stressed the difference between observations and inferences. Observations are pieces of information we obtain by using our senses, and inferences are like a “story” that we can make up based on our observations.

Mystery Footprints – Observation vs. Inference


This is another start of the year activity I am going to use to stress the importance between observation and inference. I have a ppt & worksheet for class (left side) and a homework assignment (right side) for this lesson.

I’ll start with the power point and have the students write down their observations and inferences as I show one frame at a time. There is a lot of room for interpretation and I look forward to what they come up with!

  • This is the power point I modified for my class: Mystery Footprints
  • UPDATED 9.16.09 – (I had a few typos towards the end, so the corrected version is posted. My 5′s are so helpful in pointing this out!) This is the booklet of notes and where they write down their observations and inferences: Footprints pdf. To make the booklet, copy two sided, fold in half, and glue the 4th page into the notebook. (I found this lesson last year but can’t find the link I downloaded it from. I reformatted it, but other than that there are only minor changes)
  • And this is the practice assignment for homework and review: Practice pdf
