Outcomes

In this lesson you will learn about:

1. Rounding off numbers.
2. Estimating answers to calculations.

This YouTube video explores the concepts of approximations and estimations.

Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms. 

Outcomes:

• Design a diet and exercise regimen.
• Estimate the number of calories required for basic survival.
• Estimate the number of calories burned by exercise.
• Explain how heart health depends on diet and exercise.
• Explain how Body Mass Index (BMI) depends on weight and height.

Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.

Online problems where the student is required to simplify the expression using the product property of exponents.
