Studying Bugs!




Last week in science, we did experiments with bugs to determine their preferred environment. Since all biomes have special sunlight, soil, temperature and precipitation conditions, we wanted to find out what conditions these critters would choose.

First, we set up bug runs with three types of soil: dry, moist and wet. We observed the darkling beetles and isopods to see where they went. At the end of the experiment, we concluded that beetles prefer dry soil and isopods like to be where it's wet.

Next, we did an experiment to find out if they prefer a light or dark environment. We found out that both isopods and beetles prefer a dark environment.

Working together in groups was so important during these activities. Everyone learned how important it was to cooperate, listen carefully to directions, compromise with group members and help each other stay on task.

Mystery Seeds...Revealed!


Our mystery seeds are growing zinnia plants! Now that the science experiment has been completed, many students wanted to bring a plant or two home to watch it grow and flower. They carefully scooped the baby plants into a cup and added a lid for safe transport home. As they grow, they will need to be transplanted into a bigger pot.  I will be anxious to hear how the plants are growing at home!

Planting Seeds

On Wednesday, the science classes planted seeds to begin our terrarium experiments. Mrs. Byriel brought some Mystery Seeds that we could plant for an experiment. Before we decided on an experiment, the students brainstormed questions a biologist might ask about seeds.  Then we noted which questions were testable and which would need to be researched. Finally we voted on which testable question we wanted to use for an experiment. Some classes chose "How much precipitation does a plant need to survive?" Another class chose "What kind of soil does this plant grow best in?"


It was a great day of cooperation in our classroom! Each group decided on jobs for its members. The students all worked well together as they scooped dirt, measured water, counted tiny seeds, planted and marked them with toothpick flags.

Next week we will observe any changes in our terrarium  and look for signs of plant growth.
