Question

hypothesis activity
the format for writing a hypothesis is:
if (describe specifically what you will do in the experiment) then (predict the outcome of the experiment
based on your \if\ statement.)
for each problem or question, write a hypothesis.
example: i wonder if chocolate may cause pimples?
if _ visit a chocolate candy bar _ then
_ will get pimples_

1. will plant growth may be affected by the color of the light?

if ___
then ___

1. are there more bacteria on the toilet handle or on my science desk?

if ___
then ___

1. which lunch will give me more energy, chicken sandwich or pizza?

if ___
then ___

1. do birds with longer or shorter wings fly faster?

if ___
then ___

1. does caterpillar poop weigh the same as the leaf it eats?

if ___
then ___

1. bob wondered if giving detentions for missing homework would lower the amount of homework missed in his local

middle school. he recorded the number of missed homework for 30 days, and then the school agreed to assign
detentions for each missed homework assignment. he then compared the numbers to see if the policy had any effect.
if ___
then ___

1. does t.v. time seem to affect the reading scores of fourth graders?

if ___
then ___

1. does wing length affect the distance a plane flies?

if ___
then ___

1. bob wants to see if different smells travel at the same speed. he sprays a can of hairspray, peppermint air freshener,

and insect repellant at the same time. six friends stand around him in a large circle, five feet from the center of the circle
where bob stood.
if ___
then ___

Explanation:

Step1: Follow hypothesis structure

Use "If (experimental action), then (predicted outcome)"

Step2: Draft for each question

Tailor to each scenario's variables
1.
If plants are grown under different colored lights,
then plants under blue light will have the fastest growth.
2.
If bacteria samples are taken from a toilet handle and a science desk,
then the toilet handle sample will have more bacteria.
3.
If I eat a chicken sandwich for lunch instead of pizza,
then I will have more sustained energy through the afternoon.
4.
If we test flight speed of long/short wing birds,
then birds with longer wings will fly faster.
5.
If we weigh caterpillar poop and the leaf it ate,
then the poop will weigh less than the original leaf.
6.
If detentions are assigned for missed homework,
then the number of missed homework assignments will decrease.
7.
If fourth graders have increased daily TV time,
then their reading test scores will be lower.
8.
If we test planes with different wing lengths,
then planes with longer wings will fly a greater distance.
9.
If different sprays are released at the same time,
then all sprays will be detected by friends at the same time.
