Which cereal stays crunchier for longer??? (No one likes soggy cereal) Aim: To observe which cereal absorbs the most milk Hypothesis: The Weetabix will absorb milk the quickest due to its large mass. Equipment: 4 bowls‚ sift‚ measuring cylinder‚ 4 different types of cereal Variables; Independent variable: Cereal Dependent Variable: amount of milk first placed in the bowl. (250mL) Risk assessment: A bowl might fall onto the ground and cut someone

Problem (2 Points) Sea turtle populations are falling due to human interference with nesting. Research (2 Points) Coastal development and human activity are disturbing turtle nesting cycles. Due to this‚ sea turtle populations are falling. Hypothesis (4 Points) If the drop in sea turtle population is caused by human interference‚ then areas with lower human interference will have more successful sea turtle nesting. Procedure (4 Points) 1. Choose a large area of coastline and ocean (25 mi

and semantic meaning. To do this we needed a camera to film the experiment‚ around 20 year 8 students and a classroom. In this investigation our independent variable was how 11-13 students would memorize different objects in different ways. Our hypothesis was that we think by looking at pictures students would memorize and study things better than just by looking at the word itself. To carry out the experiment we showed the students 21 pictures and then asked simple question about the picture e

There are 2 categories minus 1. The degrees of freedom is 1. 8. Find the probability (p) value for 1 degree of freedom in the 0.05 row. Compare this with the chi–square value you calculated in your Lab Notebook. What can you say about the null hypothesis? The probability value for 1 degree of freedom in the 0.05 row is 3.84 and the chi-squared value is 0.4848. There is little statistically significant difference between observed results of the experiment and the expected results.

involved in using in an investigation such as this I am going to use Daphnia (water flea) to conduct this experiment. Although humans and Daphnia are very different organisms‚ the affect that alcohol has upon the heart should be similar. Hypothesis: The hypothesis I am going to test during the investigation is: ‘Increasing the percentage of concentration of alcohol (a depressant) solution‚ into which a Daphnia is immersed‚ will significantly cause its heart rate to decrease.’ Background Knowledge:

After statistical analysis‚ the results showed that classical music does not have a significant effect on recall‚ thus the null hypothesis was accepted.

Scientific Method The scientific method is a form of discovery science. Discovery science is when observations and measurements can be verified with data. Applying the scientific method usually requires six steps. These steps are observation‚ question‚ hypothesis‚ prediction‚ conclusion‚ and results. Not all scientists use these steps in the same way. I own a 55 gallon aquarium with koi‚ “algae eaters‚” and three breeds of tropical fish. Just today I used the scientific method to solve the problem of a
