Your teacher asks you to design an experiment that shows how plants respond to changes in their environment. You have two identical sprouted seeds to do your experiment, and you may add any other equipment of your choosing. Using the scientific method, design an experiment that meets your teacher’s criteria. Match each step of the scientific method with a step of the experiment.
Tiles:
Make observations.
Ask a question.
Test the hypothesis.
Analyze the results, and make a conclusion.
Test or modify.
Boxes:
Plant one sprouted seed with its stem
pointing up. Plant the other sprouted
seed so its stem points down, in the
direction that roots grow. Observe
the direction of growth of the stems.
If you observe no change, repeat the
experiment. If there is a change, repeat
the experiment for one or two more trials
to ensure that the stem always grows up,
against the direction of gravity.
Do the stems of plants always grow up
even when the seed is turned so the
stem points down?
Determine whether the direction that a stem
points affects the direction in which the stem
grows.
The stems of plants grow up, against the
direction of gravity.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
