Objective

By the end of this lesson, you will understand the scientific method by conducting an experiment to determine if a drink umbrella can be used as a parachute.

Materials and Prep

• Drink umbrella
• Scissors
• String
• Tape
• Ruler
• Pen or pencil
• Small object to act as a weight (e.g., a paperclip)

Before starting the lesson, make sure you have a clear understanding of the scientific method and how to conduct an experiment.

Activities

1. Start by discussing the scientific method with your student. Explain the steps involved: observation, question, hypothesis, experiment, analysis, and conclusion.
2. Ask your student to observe the drink umbrella and come up with a question related to it. For example, "Can a drink umbrella be used as a parachute?"
3. Help your student form a hypothesis by asking them what they think will happen when they drop the umbrella from a height.
4. Set up the experiment by attaching a string to the top of the umbrella and securing it with tape. Make sure the string is long enough to allow the umbrella to fall freely.
5. Measure and record the height from which you will drop the umbrella. Use a ruler to ensure accuracy.
6. Attach a small object, such as a paperclip, to the bottom of the umbrella to act as a weight.
7. Hold the string at the desired height and let go, allowing the umbrella to fall.
8. Observe and record what happens to the umbrella as it falls. Does it act like a parachute or not?
9. Analyze the results with your student. Was their hypothesis correct? What can they conclude from the experiment?
10. Discuss the importance of conducting multiple trials and making sure the experiment is fair by keeping all variables constant except the one being tested.

Second Grade Talking Points

• "Scientists use something called the scientific method to investigate and answer questions about the world around us."
• "The first step of the scientific method is observation. This means carefully looking at something and noticing its characteristics."
• "The second step is asking a question. This is when we wonder about something and want to find out more."
• "The third step is making a hypothesis. A hypothesis is like an educated guess about what we think will happen in an experiment."
• "The fourth step is conducting an experiment. This is when we test our hypothesis to see if it is true or not."
• "The fifth step is analyzing the results. We look at the data we collected during the experiment and see if it supports our hypothesis or not."
• "The final step is drawing a conclusion. We use the information we gathered to make a final statement about what we learned."
• "In our experiment, we will be testing if a drink umbrella can be used as a parachute. We will drop the umbrella from a height and observe what happens."
• "Remember, it's important to conduct multiple trials to make sure our results are consistent."
• "By the end of this experiment, we will be able to tell if a drink umbrella can act like a parachute or not."
