Investigation

Starting the Research Investigation

1. Choose a claim

2. Conduct research --> make a research question

3. Use data/trends to make conclusions about research question (answer your question)

4. Tweak and collate!

Multiple Choice

What does CER actually stand for?

• Claim Extra credit Rational

• Creative Extra Reasoning

• Claim Evidence Reasoning

• Claim Evidence Renissance

Multiple Choice

The C-E-R framework is used for

• writing specific and accurate scientific explanations

• organizing data from a lab investigation

• analyzing patterns in data

• creating drawings of scientific concepts

Claim

• This should be a sentence/statement (that you choose from the options presented)

• In Science, Claims should be based of evidence - not an opinion.

• You are going to investigate whether there is evidence to prove or disprove the claim.

• A Claim should answer a question.

Multiple Choice

What is a good description for claim?

• Any statement

• A statement that answers a question

• A question

• A piece of evidence

Multiple Choice

What is an example to a scientific claim that can be proven with evidence?

• Basketballs will bounce higher when filled with more air.

• I think Taylor Swift is the greatest singer alive.

• Plants hate filtered light

• Onions smell really bad.

Evidence

• In a scientific CER, the evidence you gather to answer your research question should include data to prove or disprove the claim.

• Data can be qualitative or quantitative.

• Quantitative = numbers, percentages, numerical

• Qualitative = evidence observed (size, shape, colour, etc)

Multiple Choice

What is a good definition for evidence?

• A statement that answers a question

• All data and facts

• Data/facts that support your claim

• Reasoning that justifies your evidence

Multiple Choice

Which of these is relevant evidence to this claim: Plants in bigger pots will grow taller.

• My family has a computer at home.

• Some plants grow taller than others.

• According to the data, a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall.

• We observed 10 plants total.

Multiple Choice

Which of the following is the most effective evidence to support the claim that "Wave power is the future of renewable energy"?

• Wave energy offers a high energy density compared to other renewable sources, which makes it more effective in generating energy. It has the potential to cover 10% of global electricity consumption due to its abundant and renewable nature.

• Wave energy converters, such as the LIMPET, have proven capable of generating significant amounts of power, successfully integrating with the UK's electrical grid to power over 400 homes on the Scottish island of Islay.

• The development and testing of various wave energy converters around the world indicate that wave power is not only viable but has started being integrated into energy systems, demonstrating its readiness for broader deployment.

• While wave power holds great promise due to its high potential and renewable nature, the high costs and technological challenges associated with the development and maintenance of wave energy converters present significant barriers to its widespread adoption.

Reasoning

Your reasoning should explain how the evidence supports your chosen claim.

Multiple Select

What is the purpose of reasoning?

• To fill up the word count

• We need to connect the evidence to the original claim

• We need to justify the evidence

• All of the answers are correct

Multiple Choice

Which reasoning explains the following evidence? "Wave energy offers a high energy density compared to other renewable sources, which makes it more effective in generating energy. It has the potential to cover 10% of global electricity consumption due to its abundant and renewable nature​​."

• Wave energy's high density means that it can produce more energy from a smaller physical footprint than solar or wind energy, which typically require more space to generate equivalent power.

• Wave energy allows for the consistent generation of power even during periods of low wind or sunlight, ensuring a more reliable energy source.

• The abundant nature of wave energy, derived from the vast oceans, suggests that it can continuously provide energy without the risk of depletion, unlike fossil fuels.

• Wave energy's effectiveness and potential coverage of global electricity needs stem from its capacity to be easily stored and transported to areas far from coastal regions.
