Question: How many Calories are found in a single Peanut.

Hypothesis:If…. then

Materials:

Procedures:

Write the steps. Number each step.

Draw your set up

Data:

  1. Data Tables (title) – CALCULATE THE AVERAGE
  2. Observation table
  3. Show your calculations
  4. Graph the calories of each peanut and also the graph of the average number of calories per peanut. So your graph should have 4 bars. Label the y and X axis and include tittle

Conclusion:

  1. Answer the question (claim).
  2. Use evidence from the lab to back up your claim. This means you need to include your measurements into your answer ( typically the average). When referring to your answers include the units.
  3. Reasoning. Why did the peanut have that amount of energy?
  4. Make sure you bring in some of your observations into your reasoning.
  5. Was your hypothesis supported or rejected? What was your hypothesis? Was the amount you obtained in the lab close to the amount of calories you predicted?
  6. What else did the results tell you (data analysis).
  7. Error analysis.

What is the actual amount of calories per peanut assuming that the average weight of a peanut is____g. What was your error %.

Give an explanation of why the calories you calculated from the lab (results) are not the same as the actual Calories in a peanut. In other words why did you have that error difference? (What went wrong. What control variable did you not control for? How can the lab be improved.)

Design and draw a better set-up for this experiment. Design a laboratory tool that would be more efficient in transffering heat from a burning metarial to a quantity of water.

“In this laboratory it was calculated that there are _____ Calories per gram of peanut. If on average, a peanut weighs_____ grams this means that on average one peanut has ______Calories. These results contradict/support the hypothesis which stated that a peanut would have _____ Calories. (ifits not supported, state how far off you were). A peanut has calories that come from stored ______. This energy is used for ______. During the burning of peanut we noticed that……______. (State anything else you learned from the data).

The actual number of calories in a peanut is ______per gram. If again it is assumed that on average a peanut weighs ______grams then the actual Calories per peanut are ______Cal. However, the results from this lab showed that a peanut had ______Calories. This results in a percentage Error of ______%. The reason that our calculated number of Calories differ from the actual Calories is because______.

The experimental design can be improved by ______.

A laboratory tool that would be more efficient in transferring heat from a burning material to a quantity of water would be the following”
