Use watering can to pour water At the high end of the box, record what happens.
Review your results. Do they support your hypothesis?
Explain.
Can anything be done to prevent or ease the damage caused by land slides? Use your results to explain your answer.
What do you think would happen if you placed the barrier near top of the hill. What if one barrier were at top and one were at the bottom? What if every house had fence around it? Write a hypothesis for one of these ideas or forms your own.
Design an experiment to test your hypothesis. Remember to record your observations, run several tests and draw conclusions from your results.
To answer the question about predicting what would happen to the soil in a heavy rainstorm, the student conducted an experiment using a planter box and various materials such as rocks, twigs, wooden blocks, and water. The experiment involved three different steps with different configurations of barriers in the planter box. Let's analyze the steps, predictions, and observations for each of these configurations:
Step 3:
- Prediction: No wall or barrier.
- Observation: Record what you observed in this step.
Step 5:
- Prediction: Wall near the top.
- Observation: Record what you observed in this step.
Step 6:
- Prediction: Barrier near the bottom.
- Observation: Record what you observed in this step.
The student also performed step 4, which involves pouring water with a watering can at the high end of the box. The results of this step should be reviewed to determine if they support the initial hypothesis.
Now, moving on to the question about land slides and how to prevent or ease the damage caused by them. The student is asked to use their results to explain their answer. They should analyze their observations from the previous experiments to draw conclusions about potential measures to prevent or mitigate landslide damage.
Next, the student is asked to make predictions about different scenarios related to placing barriers at different locations. They are also prompted to form a hypothesis based on one of these ideas or come up with their own. The student should use their prior knowledge and observations as a basis for these predictions and hypotheses.
Finally, the student is asked to design an experiment to test their hypothesis. They should remember to record their observations, run several tests to gather sufficient data, and draw conclusions from the results. It is important to approach this experiment systematically and ensure all relevant variables are controlled or observed.
Overall, the student should carefully analyze their observations, make connections to real-life scenarios, and utilize critical thinking skills to effectively answer the questions and design the experiment.
