###
Proving an Ecosystem’s Health Through Succession

**Students engage in viewing day three of ecosystem changes in lab groups to determine if the ecosystem is healthy or unhealthy based on scientific data and factors. **

###
Mendelian Genetics Using Monohybrids

Students will work collaboratively through a fictitious, real-world scenario to determine the probability of each breeding pair of dogs producing offspring with the desired trait for a fictitious client.

###
Producing Plump Produce

In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.

###
Demonstration and Analysis of Dihybrid Crosses

The students will review related vocabulary, watch the teacher model a dihybrid cross, and then perform a dihybrid cross and answer questions about the outcomes with a partner.

###
Using Theoretical and Experimental Probability to Make Predictions

Given an event to simulate, the student will use theoretical probabilities and experimental results to make predictions and decisions.

###
Plant, Parts, and Function

Students use prior knowledge of body systems as they make connections to systems in plants. Students learn that some plant systems have similar functions as the respective animal systems. The lesson highlights the following systems in plants: root system, shoot system, vascular system, and reproductive system.

###
Using Multiplication by a Constant Factor

Given problems involving proportional relationships, the student will use multiplication by a constant factor to solve the problems.

###
Generating Different Representations of Relationships

Given problems that include data, the student will generate different representations, such as a table, graph, equation, or verbal description.

###
Predicting, Finding, and Justifying Data from a Table

Given data in table form, the student will use the data table to interpret solutions to problems.

###
Predicting, Finding, and Justifying Data from a Graph

Given data in the form of a graph, the student will use the graph to interpret solutions to problems.

###
Determining Slopes from Equations, Graphs, and Tables

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.

###
Predicting, Finding, and Justifying Data from Verbal Descriptions

Given data in a verbal description, the student will use equations and tables to solve and interpret solutions to problems.

###
Energy Transfer in an Ecosystem

All matter contains energy. Energy can be transferred from one object to another. Energy transformation can occur through the conversion of energy from one form to another. Energy is never created nor destroyed; it is always transferred and/or transformed. Students will demonstrate how energy is transformed and transferred in an ecosystem. To do this, students will create energy pyramids by stacking cups that represent organisms and available amounts of energy. Students will graph and analyze the data.

###
Approximating the Value of Irrational Numbers

Given problem situations that include pictorial representations of irrational numbers, the student will find the approximate value of the irrational numbers.

###
Expressing Numbers in Scientific Notation

Given problem situations, the student will express numbers in scientific notation.

###
Taxonomy Standards

Given examples, students will recognize the importance of taxonomy to the scientific community.

###
Taxonomy: Major Groups

Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.

###
Homeostasis: Ecological Systems

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.

###
Biological Systems: Homeostasis

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.

###
Relationships Between Organisms: Food Chains, Webs, and Pyramids

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.
