Title: How can I perform an experiment using the steps of the scientific method?


1
Scientific Method
  • How can I perform an experiment using the steps
    of the scientific method?
  • Can I change the data I have collected from an
    experiment into a table, graph, or diagram?

2
Step 1 Question/Observation
  • Would people prefer to eat spiders or worms?

3
Step 2 Research
  • Ask other people and look up information.

4
Why do people eat worms?
  • Silk worms make up the main ingredient in a very
    popular dish in Korea. It was originally made
    with rotten baby worms, but evolved to use
    freshly dead male worms. The worms are battered,
    crumbed, and fried in oil. In some places they
    are merely skewered and fried (as is seen in the
    picture below).

5
Why do people eat Spiders?
  • The thought of eating spiders probably makes most
    of us queasy, to say the least. But, in various
    parts of the world, spiders are a delicacy. You
    can buy them at road-side stalls in Cambodia,
    where people developed a taste for them when they
    were being starved to death by Pol Pot.

6
Step 3 Hypothesis
  • Educated guess
  • Task Come up with your own hypothesis on what
    people would rather eat worms or spiders.
  • Remember to explain yourself.

7
Reality Check
  • How can I perform an experiment using the steps
    of the scientific method?

8
Step 4 Experiment
  • Tests your hypothesis.
  • Example Take a survey and see what the majority
    of people would eat.

9
Reality Check
  • Can I change the data I have collected from an
    experiment into a table, graph, or diagram?

10
Table, Graph, or Digram
  • Create a table to show the data you collected.

11
STEP 5 CONCLUSION
  • Accept or reject your hypothesis.
  • Explain why your hypothesis was correct or
    incorrect.

    experiment into a table, graph, or diagram?

Creepy facts
  • The most commonly eaten worms around the globe
    include agave worms, sago worms and mealworms.
    Most people describe these worms as nutty and
    creamy. One popular way people prepare these
    worms is by frying them just like you'd fry
    crickets or locusts. These common worms are eaten
    all throughout the world

Creepy facts
  • Fried spider is a regional delicacy in Cambodia.
    In the Cambodian town of Skuon, the vending of
    fried spiders as a specialty snack is a popular
    attraction for tourists passing through this
    town. Spiders are also available elsewhere in
    Cambodia in Phnom Penh for instance but
    Skuon, is the center of their popularity. The
    spiders are bred in holes in the ground in
    villages north of Skuon, or foraged for in nearby
    forestland, and fried in oil. It is not clear how
    this practice started, but some have suggested
    that the population might have started eating
    spiders out of desperation during the years of
    Khmer Rouge rule, when food was in short supply
