Middle School Nature of Science Supplement Overview

Time4Learning offers an online, interactive middle school science curriculum that can be used for homeschool, afterschool, and summer education. At the middle school level, science is organized into courses that cover materials typically offered at the sixth to eighth grade level, although parents can register students in fourth grade and above as part of membership.

Nature of Science is a supplemental course, recommended for use alongside middle school Life Science, Physical Science, and Earth/Space Science. It teaches students how to safely and correctly use scientific equipment, take measurements, conduct experiments and investigations, collect and analyze data, draw conclusions, evaluate evidence, and present their work to others.

This page includes information about the materials covered in the middle school Nature of Science supplement.

Chapter 1 – Experimentation

The materials in this chapter introduce and cover the concept of experimentation. It is organized into sections that teach, reinforce and test students on the concepts of lab safety, experimental questions, predictions and hypotheses, hypotheses and theories, measurements, using scientific tools, observations and data collection, characteristics of a scientific experiment, independent and dependent variables and controls, designing an experiment, repetition and replication, and descriptive investigations.

Lessons in this chapter are organized into the following sections:

  • Lab safety – Students are taught how to correctly use safety equipment while conducting an experiment.
  • Experimental questions – Students will learn how to identify testable scientific questions.
  • Predictions and hypotheses – Students must be able to create a prediction or hypothesis for a scientific investigation.
  • Hypotheses and theories – Students learn to explain how hypotheses are revised and tested to eventually produce scientific theories.
  • Measurements – Students are taught how to identify and be able to make metric (SI) measurements for length, temperature, mass, and time.
  • Using scientific tools – Students are taught how to safely use appropriate tools to make SI measurements, including meter sticks, thermometers, balances, and stopwatches.
  • Observations and data collection – Students learn how to distinguish between observations and other information including inferences, make observations, and collect data in a table or chart.
  • Characteristics of a scientific experiment – Students must be able to describe the characteristics of a scientific experiment and identify situations in which experiments are useful.
  • Independent and dependent variables and controls – Students are taught how to identify independent and dependent variables, and factors which should be controlled in an experiment.
  • Designing an experiment – Students must be able to design an experiment to investigate a scientific problem.
  • Repetition and replication – Students learn how to describe the importance of conducting multiple trials in an experiment and having results verified by other scientists.
  • Descriptive investigations – Students must learn how to differentiate between description and explanation, and conduct a descriptive investigation.

Chapter 2 – Data Analysis

The materials in this chapter introduce and cover data analysis. It is organized into sections that teach, reinforce and test students on the concepts of understanding data, accuracy and precision, circle and bar graphs, linear graphs and scatter plots, and scientific models.

Lessons in this chapter are organized into the following sections:

  • Understanding data – Students are taught how to identify patterns in data using statistical methods such as mean, median, mode, and range.
  • Accuracy and precision – Students learn to describe the accuracy and precision of experimental data.
  • Circle and bar graphs – Students learn how to create and interpret circle and bar graphs.
  • Linear graphs and scatter plots – Students must be able to create and interpret linear graphs and scatter plots.
  • Scientific models – Students are taught how to identify the advantages and limitations of different scientific models.

Chapter 3 – Drawing Conclusions

The materials in this chapter introduce and cover drawing conclusions. It is organized into sections that teach, reinforce and test students on the concepts of research, making conclusions from data, presenting experimental results to others, and evaluating scientific evidence.

Lessons in this chapter are organized into the following sections:

  • Research – Students must learn how to conduct research about a topic in science using sources such as books, magazines, and internet sources.
  • Making conclusions from data – Students are taught to draw conclusions and predict trends based on scientific data.
  • Presenting experimental results to others – Students learn how to communicate the steps and results from an investigation in written reports and oral presentations.
  • Evaluating scientific evidence – Students must learn how to distinguish valid sources of information and samples of data, identify flaws in reasoning, and recognize alternate interpretations of data.

The Time4Learning Program Structure

Time4Learning has been refined through years of feedback from educators, parents, and students. Subjects are organized into chapters composed of interactive lessons, printable worksheets, quizzes and tests. Students are guided through the activities at their own pace by an automated system.

When students log in, they choose a subject, select a chapter, pick a lesson and complete the activities. A bright green arrow tells them where they left off, and completed work is clearly labeled with a check-mark or a gold star. Visual and auditory prompts guide students through the lessons, making it easy for even young learners to follow, and an online playground (controlled by parents) rewards and motivates them to finish their lessons.

Parents get access to printable lesson plans, teaching tools, detailed reporting and parental support through our online Parent Forum.

Does your child have different achievement levels for math and language arts? No problem! Time4Learning lets you set each individual subject at the appropriate graded level, making this program great for special needs and gifted students.
