Key scientific terms and definitions include:

• Energy: The ability to do work, which exists in various forms such as heat, light, and motion.
• Matter: Anything that has mass and occupies space, composed of tiny particles called atoms.
• Force: A push or pull that can change an object’s motion.
• Ecosystem: A community of living organisms and their physical environment, interacting with each other.
• Adaptation: A trait or behavior that helps an organism survive and reproduce in its environment.

Experimental Design

Designing and conducting scientific experiments are crucial skills in grade 8 science. Students learn the steps involved in the scientific method, which provides a systematic approach to investigating scientific questions.

Key steps in experimental design include:

1. Formulating a hypothesis: A testable prediction based on observations and prior knowledge.
2. Designing a controlled experiment: Identifying variables (independent, dependent, and controlled) and ensuring fair testing conditions.
3. Collecting and analyzing data: Using appropriate methods to gather and interpret data from the experiment.
4. Drawing conclusions: Based on the data analysis, determining whether the hypothesis is supported or not.

Data Analysis and Interpretation, Elevate science grade 8 answer key

Grade 8 science emphasizes the importance of analyzing and interpreting scientific data. Students learn to use tables, graphs, and other visuals to represent and summarize data.

Key concepts in data analysis include:

• Mean: The average value of a set of data.
• Median: The middle value of a set of data when arranged in order.
• Mode: The value that occurs most frequently in a set of data.
• Range: The difference between the highest and lowest values in a set of data.
