Julie took her lunch to work every day. She wanted to know what type of insulation would keep her lunch the coolest. Each day, she took her lunch in a different container: a Styrofoam cooler box, a plastic cooler box and a soft insulated lunch bag. She measured the temperature inside her lunch container every day at noon. She repeated this process for 9 days. In the end, she knew exactly which lunch box to use to keep her lunch the coolest.
How did Julie follow the scientific method? What steps did she include, what steps are missing? What would be the conclusion of the experiment? Remember to include vocabulary from the unit.
I'll be glad to check your answer.
i don't know what the answer
To determine which type of insulation would keep her lunch the coolest, Julie followed the scientific method, which is a systematic process used to investigate the world around us. Let's break down how Julie followed the steps of the scientific method and identify any missing steps:
1. Observation: Julie noticed that her lunch would get warm by lunchtime, and she wanted to find a way to keep it cooler. This led to her question on which lunch container would be the most effective insulation.
2. Research and Background Information: Before conducting the experiment, Julie might have looked up information about different types of insulation and their thermal properties. This step was not explicitly mentioned but would be important to gather relevant information and make informed choices for the experiment.
3. Hypothesis: Julie formulated a hypothesis, which is a proposed explanation for the question or problem being investigated. It could be something like: "The Styrofoam cooler box will keep my lunch the coolest due to its insulating properties."
4. Experiment: Julie conducted an experiment by taking her lunch in three different containers over nine days - a Styrofoam cooler box, a plastic cooler box, and a soft insulated lunch bag. She measured the temperature inside each container every day at noon, ensuring a consistent time of measurement.
5. Data Collection: Julie recorded the temperature measurements for each lunch container throughout the nine-day experiment. This would involve using a thermometer to measure the temperature inside the containers at noon.
6. Analysis: Julie analyzed the data she collected, comparing the temperature readings for each lunch container. She looked for patterns, trends, and variations in the data.
7. Conclusion: Based on her analysis, Julie would be able to draw conclusions about which lunch container provided the best insulation. The conclusion might state that the Styrofoam cooler box kept her lunch the coolest, followed by the plastic cooler box, and the soft insulated lunch bag had the least effective insulation.
Missing Steps: Although the experiment and conclusion were mentioned, a few important steps seem to be missing in the description. These include the formulation of a hypothesis, research and background information gathering, and detailed analysis of the data collected. These missing steps could have further strengthened Julie's experiment and conclusions.
The conclusion of the experiment would be the finding that the Styrofoam cooler box provided the most effective insulation, keeping Julie's lunch the coolest.
