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.
Glaciologist in Action (Lab)
Students participate in a hands-on lab in which glacier (ice) effects on the Earth’s surface is demonstrated.
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.
Push Back, Pull Forward
Students will conduct an experiment to demonstrate force such as pushes and pulls.
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.
In this lesson, students will investigate how gene expression is a regulated process controlled by DNA and the interpretations of codons through translation.
Save the Factory!
Students will design an experiment to test the outcome of friction in force and motion. The students will create an inclined plane demonstrating their knowledge of mechanical energy and the effects of gravity on an object. Students will use previous knowledge of friction to complete their task of stopping their object. Critical thinking skills will be the focus of the lesson as students will have to utilize their scientific problem-solving skills to make decisions regarding their experiment.
Texas Essential Knowledge and Skills (TEKS) Vertical Alignment
Click below to learn about the TEKS related to the unit and Research Lesson. The highlighted student expectation(s) is the chosen focus for the Research Lesson.
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.
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.
Consumers and Producers
Students will investigate various ecosystems to determine what producers and consumers are, as well as their needs within an ecosystem.
What’s the Verdict? An Investigation of Herbicide Drift on Grapevines
Students will investigate the possible effects of herbicide drift on grape production by making inferences from an article about a local vineyard and using various experimental materials.
Students will model real-world formulas and chemical reactions to investigate the meaning of limiting reactants.
