Take a Bug Expedition!
Take a walk outdoors and practice observing, tallying, and categorizing while
you're at it!
What you need:
· A patch of bug-
filled open space
such as a yard,
park, or neighbor-
What you do:
1 What types of bugs do you expect to find when you take your walk? Make a
chart showing these bugs. Leave blank spaces for any other bugs you find
along the way. Place the chart on a clipboard so you can walk around and
2. Go outdoors and make a tally mark in the appropriate column each time
you see a bug. You may want to add an "unknown insect" category to your
chart, just in case you come across anything that's not easily identifiable.
While you're walking, take time to observe the bugs, noting their size and
pattern of movement (flying, crawling, or both).
3. Make a bar graph to show the bugs you found. List the types of bugs on the
left, and then on the horizontal line, write numbers 0 to the greatest
amount you tallied. Then make bars to show the data. For example, if your
data shows 4 bees, draw a bar to number 4 on the graph. Continue until you
have represented all of the tally marks on the graph.
4. What does your data show? Which bugs did you see most or least often?
Bar graphs make your comparison of bugs easy and fun!
As you observe your visitors, observe their similarities and differences. You
may just become a bugwatcher for life!
