Anders experimented with planting seeds using two methods. He tried “seed balls” and then “hand planting”. Seed balls are made by mixing seed, clay, and compost together and forming a ball shape, then tossing them out on the land. Hand planting involves placing the seed in the ground individually, one by one. He measured out a plot of bare land and divided it into three sections. One section would have seed balls, one would have seeds that were planted by hand, and one would not be planted at all. In Anders experiment, what is the independent variable?

• the percentage of the land that had seeds sprout

• the amount of rain that falls

• the methods of seed planting

• the ingredients of the seed balls

When Anders tried his experiment, he made observations and recorded his data in a chart. On the land that was planted using seed balls, what percentage of the land was still bare ground?

• 43%

• 35%

• 65%

• 70%

Which of the following might have been a reasonable hypothesis that Anders would have made?

• Planting seeds with seed balls is fun and educational.

• If seeds are spread out across the 3 sections of land, then the seeds that land on bare ground will

  not sprout unless it rains on at least half the ground.

• If seeds are planted using the seed ball method, then a higher percentage of the bare land will

  have seeds sprout.

• If seeds are planted on bare land, then seeds will sprout at a 50% rate.

Why did Anders leave one section of land alone with no specific planting method?

• He could not think of another method to use on that plot.

• He was using this plot as a “control” for his experiment.

• He ran out of supplies.

• He needed that part of the land to use for another experiment.

What conclusion (based on his data) can Anders make after his experiment?

• Planting with seed balls did not make a significant difference in the land with seeds that

  sprouted, but hand planting the seeds had the most percentage of land with seeds that sprouted.

• If you leave the land alone, you will get more seeds to sprout than if you plant them.

• Planting seeds is a difficult job and requires much attention.

• Planting seeds using seed balls was the best method to get seeds to sprout.
