Cell Specialization and Differentiation
Given examples, descriptions, and illustrations, students will be able to describe the role of DNA, RNA, and environmental factors in cell differentiation.
Producing Plump Produce
In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.
Teacher explains the task to the students
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.
Students working on the task
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.
3.04 Bar Charts
In this video, students learn about bar charts as well as how to read and construct one.
3.05 Comparing Distributions
In this video, students will compare bar charts, pie charts, and frequency tables to see differences in results.
2.01 Sample Surveys
In this video, students are introduced to surveys and the idea that substantial size and random selection are necessary for good results.
2.02 Sources of Bias in Sampling and Surveys
In this video, students learn about the bias that occurs in sampling.
2.03 Sampling Methods, Part 1
In this video, students learn various ways of obtaining sample data.
2.04 Sampling Methods, Part 2
In this video, students continue with practice problems about different sampling techniques.
2.05 Experiments vs. Observational Studies
In this video, students explore the differences between experiments and observational studies.
2.06 Three Principles of Experimental Design
In this video, students learn about replication, randomization, and control when designing and implementing an experiment.
2.07 Lurking and Confounding Variables
In this video, students learn the difference between lurking and confounding variables and how they affect results.
2.08 Generalizability of Results and Conclusions
In this video, students learn how to interpret results and draw conclusions based on them.
6.01 Probability and the Law of Large Numbers
In this video, students are introduced to the concept of probability using the Law of Large Numbers.
6.02 Probability Terminology
In this video, students learn key terminology associated with probability.
6.03 Venn Diagrams
In this video, students represent and calculate probabilities using Venn diagrams.
6.04 Independent and Mutually Exclusive Events
In this video, students calculate probabilities for independent events and mutually exclusive events.
6.05 Contingency Tables
In this video, students calculate probabilities using a two-way contingency table.
6.06 Tree Diagrams
In this video, students calculate conditional probabilities using a tree diagram.
