are there bugs under my feet
Transcript of are there bugs under my feet
2.Pour alcohol into the Mason jar to a depth of 1-2 cm.
3.Cut the bottom out of the milk jug.
4.Tape the stick to the handle of the milk jug so it is just long enough to reach the outside bottom of the Mason jar when it is placed on top of it to make the funnel.
5.Use the hardware cloth to create a basket in the wide end of the funnel. To do this, place the hardware cloth over the open top, bending the edges of the cloth over the edge of the plastic container. You can use tape to secure the edges. Make sure you are creating a pit/basket in the middle that is deep enough to hold all your soil and gives the animals enough room to burrow down. If you are using window screen, fit it the same way, but cut numerous slits into the screen first so that larger animals can crawl through, down into the funnel.
6.Collect several handfuls of soil from different locations around your home. Be sure to label where the sample was taken from and include a date. You will use the Berlese funnel one sample at a time to collect micro-invertebrates. Or you could make several funnels, one per sample. If you have a cut or wound, you should wear latex or rubber gloves when collecting and working with the soil.
Put the soil sample, including leaf litter, on top of the wire mesh.
Carefully set the funnel on top of the Mason jar and tape the stick to the jar so it won't tip over.
7.Leave the funnel in a warm, quiet place where it won't be disturbed.
Set a lamp over the funnel, but keep the light bulb at least 10 cm away from the funnel.
Look at your samples with a magnifying lens or Loupe. What differences do you see?
Count the number of micro-arthropods and other fauna in each sample. Record your results in a data table: materials 1.one-gallon plastic milk container (1, empty)
2.Empty jelly jar (or a one-pint Mason jar) with a tight lid
3.A straight stick or rod (about 25 cm long)
1/4" mesh hardware cloth or aluminum window screen (15x15-cm piece)
5.Masking tape or duct tape
6.Black construction paper
7.Rubbing alcohol (ethyl), available at drug stores
9.Soil samples from around your home
10.Magnifying lens or Loupe controls 1.the type of plant
3. amount of soil dependent/independent variables independent
1. the type of soil
2. the amount of bugs data conclusion Hypothesis: my hypothesis is that taking the bugs out of the soil will effect the plant growth causing them to either die or begin to wilt. dependent
2.time location back yard front yard number of micro-fauna 36 19 observations the micro-fauna was black i was suggesting that they were dead. the micro-fauna kept one of the plants some what alive it was a brownish tent which meant they were still alive.
