• Work in cooperative groups conduct an experiment measuring the dehydration of apples.
• Identify and control variables in experiments.
• Collect and record data for a period of days.
• Analyze and make sense of the evidence.
• Complete a formal lab report to present the experiment.

1. Students will estimate, make and use measurements to describe and compare phenomena, and explore the structure and use of systems of measurement, including converting units within systems.

2. Students will select and use appropriate measurement units and tools to make measurements to the degree of accuracy required by the situation.

3. Students will solve problems involving the concept of, calculation of, and relationships among length, perimeter, area, volume, angle measure, capacity, weight, mass and temperature.

4. Students will use formulas and procedures for solving measurement problems.

1. Students will demonstrate knowledge of the scientific method through answering open- ended questions and laboratory experiences.

2. Students will conduct scientific investigations, which involves observations and data collection, devising and testing hypotheses, and drawing conclusions to evaluate hypotheses.

3. Students will identify and manipulate variables in an experiment.

2. Use HKMS website to complete lab report.

3. Use Excel to graph data. (optional)
