In 2015, Michael L. Smith, won an IG Nobel Prize for determining the most painful part of your body to receive a bee sting.

Question--Which part of the body does a honey bee sting hurt the most?

Identify all the pieces of evidence.

• Mr. Smith stung himself with honey bees.

• All this proves that the most painful location for honey bee stings were the nostril and upper lip because pain is more intense at locations with thinner skin.

• The nostril is the most painful location for a honey bee sting with the upper lip being the second most painful.

• On a scale of 1-10 he noticed stings at the nostril and upper lip had an average pain rating of 9 and 8.7.

In 2015, a group of scientists won an IG Nobel Prize in Physics or discovering that white horse are more “horsefly-proof”.

Question--What is the effect of horse color on horsefly attraction?

Select all the evidence.

• Brown horses stay two times longer in horsefly-free shady forest than white horses.

• Horseflies are less attracted to white horses than dark horses.

• This means that horseflies are attracted to higher polarization of light reflected from dark surfaces. Since white animals reflect light with lower polarization, fewer horseflies are attracted to white horses.

• Brown test surfaces trapped twenty-one horseflies while white test surfaces attracted one horsefly.

• Black horse models trapped twenty-five times more horseflies than white horse models.

Which of the following is the best definition of "evidence?"

• Data/facts that support your claim

• Reasoning that justifies your evidence

• All data or facts about a subject

• A statement that answers a question

You should eat a banana every day. Bananas have nutrients like potassium and magnesium. Because our bodies need potassium and magnesium to work, it is a good idea to eat a banana every day. 

 

Which is the evidence? 

• Bananas have nutrients like potassium and magnesium.

• Because our bodies need potassium and magnesium to work, it is a good idea to eat a banana every day.

• You should eat a banana every day because they have nutrients.

• Bananas are sweeter when they are ripe.

Air is matter. We found that the weight of the ball increases by .5lbs each time we pumped more air into it. This shows that air has weight, one of the characteristics of matter.
Which sentence is the claim?

• Air is matter.
• We found that the weight of the ball increases by .5lbs each time we pumped more air into it.
• This shows that air has weight, one of the characteristics of matter.

Evidence:

• Bouncy balls bounce to different heights on different surfaces

• The ball bounced to 70 cm on the floor, 40 cm on the rug, and 10 cm on the dirt

• Different surfaces absorb different amounts of energy which causes the ball to lose different amounts of energy for bouncing.

Evidence:

• Objects with a density greater than water will sink, while those with a lower density will float.

• The coin sinks to the bottom of the container, while the piece of wood and the bottle cap float on the surface.

• Density is the amount of mass per unit volume. Objects denser than water have more mass packed into a given volume and thus sink, while less dense objects displace enough water to stay afloat.
