"Sugar 2 -- Hot 4"
---
What is wrong with the presentation of results?
Units are missing
Results are just fine
Results must contain the independent variable
Results should state the hypothesis

How to best measure the mass of a cool drink in a bottle?
Place the bottle of cool drink on a digital balance
Use a graduated cylinder

Which description best defines a "hypothesis"?
A hypothesis is a record of what we actually see.
A hypothesis is an expression of what we think is happening
A hypothesis is a description which needs to be followed in order to obtain results.
A hypothesis is a general statement or explanation which can be tested by an experiment.
A student measured the heights of four other students in the class. The heights recorded

1.35 m
1.40 m
1.45 m
Which piece of equipment should you use to measure out liquids?

plant height increases each day
the plant reached its greatest possible height on Friday
the plant started to grow thicker on Thursday
the rate of growth was greatest later in the week

An hypothesis is "If you increase the amount of fertiliser given to tomatoes plants then they will produce more tomatoes".
The data showed that the control group produced 2.2 kg of tomatoes on average, while adding 20 grams of fertiliser resulted in 3.4 kg of tomatoes on average.
What is a suitable conclusion?
“The hypothesis has been supported. An increase in amount of fertiliser did increase the amount of tomatoes produced. Plants getting no fertiliser produced 2.2 kg of tomatoes; with 20 grams of fertiliser 3.4 kg of tomatoes were produced on average.”
“The hypothesis has been supported as shown by the data."
The experiment showed that fertiliser affects the growth of tomatoes."
“The hypothesis was that if you increase the amount of fertiliser given to tomatoes plants then they will produce more tomatoes. Whether the tomatoes were edible could not be determined by the experiment. The experiment was overall valid and reliable and fun too."
What are the 3 main ways to ensure experimental data is fair?
1) Ensure the experiment is valid and reliable
2) Include prior knowledge in planning
3) Discuss patterns and trends in data
1) Include a question and observation.
2) Include background and a preliminary study.
3) Write a proper hypothesis.
1) Having a control and an experimental group.
2) Controlling as many variables as possible.
3) Large sample size & averaging results.
1) Having an independent and dependent variable.
2) Having an appropriate title for your graph.
3) Ensure to write a proper method.
How do you make sure an experiment is reliable and valid?
Repeating the experiment with modified parameters and adjusting the equipment used.
Repeating the experiment and making sure the equipment & method are fit for purpose.
Repeat with different equipment at least 5 times and take the average.
Write down a hypothesis and a method and test the hypothesis.
You are to design an experiment that test the absorbency of various paper towel brands. What you really want to know is if more expensive brands also absorb better. Phrase a hypothesis for this question that can be tested with a suitable experiment.
Do more expensive paper towel brands absorb more water?
I believe that more expensive paper towel brands can absorb more water because they are more expensive.
When paper towel brands absorb more water then they must be more expensive because they use better quality material.
If paper towels are more expensive, then they absorb more water.
What type of graph would be suitable for the data table shown?
Bar graph with Paper Towel as Independent Variable and Amount of Water Absorbed as the Dependent Variable
Bar graph with Paper Towel as Dependent Variable and Amount of Water Absorbed as the Independent Variable
Line chart with Paper Towel as Independent Variable and Amount of Water Absorbed as the Dependent Variable
Line chart with Price per Sheet as Independent Variable and Amount of Water Absorbed as the Dependent Variable
