In this scientific research learning exercise, students will complete a chart by determining if the statements given are examples of quantitative research or descriptive research. Then students will fill in the blank of 8 statements...

Learners discuss ways in which dinosaurs adapted to their environments. They apply the same logic to an analysis of human habitat, survival needs, and survival need fulfillment to explain how people have adapted to their environment.

Students examine the importance of aseptic technique, become familiar with media plates, and general microbiology techniques. They study the benefits and dangers of bacteria and other microorganisms in their lives.

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Students analyze and classify substances.  In this classifying matter instructional activity, students look at various substances and identify them as heterogeneous or homogeneous mixtures, pure substances, or solutions. ...

Students explore how new advancements in technology can lead to advancements in scientific knowledge, and specifically how new technologies are advancing the study of mummies.

Students comprehend the process of making pure maple syrup. They identify differences between pure syrup and artifical maple syrup. Students are asked what is in the displayed containers. They sample the syrups and try to figure out...

Students isolate three species of bacteria using the plate streak method, implement sterile microbiology techniques, and produce pure cultures of each microorganism at the end of this exercise. They write a descriptive paragraph for each...

Students develop a method to separate different types of mixtures. In this chemistry instructional activity, students model the steps in the scientific method. They perform the experiment and analyze data.

Students define all eight water quality parameters and list at list one source for each of the eight water quality parameters. They determine how each of the eight parameters affect river ecosystems.

Students study Georg Ohm and how he changed mathematics with his law.  In this experimental evidence and stastics lesson students complete an experiment on the characteristics of Ohm's law. 

Pupils research the impacts of genetic research on homes, research laboratories, and hospitals. In this genetics lesson, students use the Internet to investigate the ways that genetics has affected our way of life. They present...

Middle schoolers utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether...

Students develop a basic understanding of how color is perceived by the eye. They utilize the technique Seurat used to paint A Sunday on La Grande Jatte to create their own paintings.

Students work in teams to use the scientific method to separate complex mixtures into pure components.

Eighth graders become familiar with Punnett squares, specifically purpose, application and interpretation. Key terms from previous lessons (included below) are reviewed/reinforced before data is applied to a Punnett square and interpreted.

Students identify the eight tests done to check for water quality. In this ecology lesson plan, students explain why it's important to test water in rivers. They explore sources of river water pollution.
