Photosynthesis 7th grade project- love the hands on …

Students learn about the effects of UV light, mutations and DNA repair on the survival of prokaryotes and the risk of skin cancer. In the first experiment, students evaluate the effects of different durations of UV exposure on survival and population growth of Haloferax volcanii. This experiment also tests for photorepair of DNA damage. Students design the second experiment, which evaluates the effectiveness of sunscreen. In addition, students answer analysis and discussion questions that promote their understanding of molecular biology, cancer, and the interpretation of experimental results. (NGSS)

Hands-on Activities for Teaching Biology to High …

In this hands-on, minds-on activity students use model chromosomes and answer analysis and discussion questions to learn how mitosis ensures that each new cell gets a complete set of genes. Students also learn how genes on chromosomes influence phenotypic characteristics and how a single cell develops into the trillions of cells in a human body. In our follow-up students learn how the movement of gene-carrying chromosomes during mitosis, meiosis and fertilization results in the inheritance of genes. (NGSS)

Over the next several years, your child will become immersed in the process of science; thinking the way scientists think and doing experiments the way scientists would. Every experiment your child performs will lead to the discovery of a science concept. Kids find it’s easy to learn science when they’re working with real science equipment and investigating interesting questions.

This activity provides a sequence of learning activities designed to optimize student learning and understanding of osmosis by beginning with a student investigation of osmosis at the macroscopic level and then moving to analyzing osmosis at the molecular and cellular levels. In Part I, "What is happening to these eggs?" students observe and analyze the effects of osmosis on eggs. In Part II, "Osmosis – Effects on Animal and Plant Cells", analysis and discussion questions introduce students to a molecular and cellular understanding of osmosis and challenge students to apply this understanding to interpreting their results in Part I and several “real-world” phenomena.

In the first part of this activity, students learn how to use the floating leaf disk method to measure the rate of net photosynthesis (i.e. the rate of photosynthesis minus the rate of cellular respiration). They use this method to show that net photosynthesis occurs in leaf disks in a solution of sodium bicarbonate, but not in water. Questions guide students in reviewing the relevant biology and analyzing and interpreting their results. In the second part of this activity, student groups develop hypotheses about factors that influence the rate of net photosynthesis, and then each student group designs and carries out an investigation to test the effects of one of these factors.

In this activity, students extract DNA from Archaea or from their cheek cells. Students learn key concepts about DNA function during the intervals required for the extraction procedure. Student understanding of DNA structure, function and replication is further developed by additional analysis and discussion questions and hands-on modeling of DNA replication. (NGSS)

This multi-part minds-on, hands-on activity helps students to understand both alcoholic fermentation and the engineering design process. In the first two parts of this activity, students learn about alcoholic fermentation and test for alcoholic fermentation by assessing CO2 production by live yeast cells in sugar water vs. two controls. The third part of this activity presents the bioengineering design challenge where students work to find the optimum sucrose concentration and temperature to maximize rapid CO2 production. Structured questions guide the students through the basic engineering steps of applying the relevant scientific background to the design problem, developing and systematically testing proposed design solutions, and then using initial results to develop and test improved design solutions.
