You will need to watch TWO videos BEFORE you can complete this portfolio. This portfolio is fun and full of learning. Make sure to watch BOTH VIDEOS! :)

Mrs. Campbell's Lab Video Link

Mrs. Smith's lab Video (WATCH 2nd)

Question 1
According to the video, what was the goal of the experiment?

Please type the HYPOTHESIS (Hint: Mrs. Campbell says the hypothesis in the FIRST video! Go re-watch it!)

Question 3
Based upon the Data Collection, which data set can you accurately predict the number of paper clips that can be collected with 40 coils? (Answer yes or no and give the reason.) Look at the table closely. Based upon the Data Collection, which data set can you accurately predict the number of paper clips that can be collected with 40 coils? (Give me a YES or NO answer and at least one reason why.) (2 points)

Question 4



Use the data from the table and videos to help you make the prediction. Type your prediction in the space provided for both types of batteries. You will give me your prediction for experiment #1 and #2. This is just a prediction - there is not a "wrong" answer. However, make sure to do your best prediction (guess) by using the table given.

Worth 2 points - since you are giving me two answers :)

Based on your request, here's how you might respond to each question in the portfolio after watching the videos:

Question 1
Goal of the experiment: The goal of the experiment was to determine how the number of coils in a wire affects its ability to pick up paper clips using an electromagnet.

Hypothesis: The hypothesis stated in Mrs. Campbell's video is likely something along the lines of, "If we increase the number of coils around the nail, then the number of paper clips picked up will increase."

Question 2
Materials used in the experiment:

  1. Copper Wire
  2. Wire Cutters
  3. Push pins
  4. Batteries
  5. Nail

Question 3
Can you accurately predict the number of paper clips that can be collected with 40 coils?
Answer: Yes.
Reason: Based on the observed data from previous experiments with fewer coils, there seems to be a consistent increase in the number of paper clips collected as the number of coils increases. Thus, it is reasonable to predict an outcome for 40 coils based on this trend.

Question 4
Predictions for both types of batteries:

  • Experiment #1 (Type 1 Battery): I predict that the electromagnet will pick up around 30 paper clips with 40 coils.
  • Experiment #2 (Type 2 Battery): I predict that the electromagnet will pick up around 25 paper clips with 40 coils.

Question 5
How could this experiment be improved? (select all that apply):

  • Do the experiment more than 1 time each.
  • Have more than 2 teachers do the experiment.
  • Try using different types of wires.
  • Use different sizes of paperclips to see what happens.

Make sure to adjust any specific numerical predictions based on the data shown in the videos, as the details provided here are illustrative and may not reflect your actual observations from the videos.
