This fun project from my book Outdoor Science Lab for Kids shows you how to collect and identify amazing arthropods using a net you make yourself. For more engaging outdoor experiments, you can order the book here, or anywhere else books are sold.
– sweep net or: two wire hangers, an old, light-colored pillowcase, scissors, pliers, long wooden broomstick or sturdy yardstick, and duct tape
– area with long grass
-large white piece of fabric, like an old sheet
– insect identification books (optional)
Safety Tips and Hints
- Don’t pick insects up with your bare hands, unless you know they don’t bite or sting.
- Ticks love tall grass. If there are ticks in your area, take precautions and do a tick check after your insects hunt.
Step 1: If you don’t have a sweep net, make one by straightening and twisting two wire hangers together. Form them into a loop, leaving about 3 inches (8cm) straight on either end. Cut about one third off of the open end of a pillow case and pull the mouth of the pillowcase over the wire loop. Tape it securely around the perimenter.
Step 2. Find an area with long grass and plants. Sweep with your net the same way you’d sweep a floor, but flip the open side of the net back and forth to capture insects in the grass.
Step 3. Close your net by flipping the bottom over the top and take it over to your large piece of fabric.
Step 4. Carefully dump the creatures you’ve collected onto the white fabric to inspect them. If you want a closer look, put an insect inside a jar with a loose lid.
Step 5. Count how many legs they have, how many body segments, look for antennae, wings and unique color. Record your observations in a notebook.
Step 6. Use insect identification books, or other means to identify what you’ve found.
Step 7. Keep a journal of the insects and arachnids you capture, the time of day, and where you found them.
The Science Behind the Fun:
When you sweep, chances are you’ll find lots of insects, which are arthropods with six legs. They often have wings, and their life cycle goes from egg to larva, to adult. Some insects, like butterflies, also go through a pupal stage, in which their bodies are significantly transformed. The antennae on their heads are sensory organs.
This morning, we made kid-sized catapults on WCCO MidMorning (Minneapolis/St.Paul)!
It’s one of the new experiments in my upcoming book, Outdoor Science Lab for Kids: 52 Family-Friendly Experiments for the Yard, Garden, Playground and Parks.
I also brought along a marshmallow slingshot , and a brand new experiment…a paper airplane launcher!
