No problem! Take your time and switch to another computer. When you're ready, I'll be here to help you with your worksheet. In the meantime, let me explain some concepts that might be helpful for you to answer the questions.
1. Prediction: A prediction is a statement that suggests what is expected to happen in the future based on observations or previous knowledge.
2. Problem: A problem statement identifies the question or issue that needs to be investigated or solved.
3. Experiment: An experiment is a planned procedure conducted to test a hypothesis or to determine the cause-and-effect relationship between variables.
4. Hypothesis: A hypothesis is a proposed explanation for a phenomenon or a prediction that can be tested through experimentation.
5. Data: Data refers to the information collected during an experiment or observation. It can be qualitative (descriptive) or quantitative (numerical).
6. Observations: Observations are factual statements based on what is directly seen, heard, or measured.
Once you're ready to answer the questions, I'll guide you through them one by one. Just let me know!
