Students use model chromosomes and answer analysis and discussion questions to learn how each person inherits one copy of each gene from each of his/her parents. As they model meiosis and fertilization, students follow the alleles of three human genes from the parents' body cells through gametes to zygotes. In this way, students learn how genes are transmitted from parents to offspring through the processes of meiosis and fertilization. Students analyze the results of crossing over, independent assortment and fertilization to learn how meiosis and fertilization contribute to genetic and phenotypic variation. Students also compare and contrast mitosis and meiosis, and they learn how a mistake in meiosis can result in Down syndrome or death of an embryo. This activity can be used to introduce meiosis and fertilization or to review these processes.(NGSS)
The Line of Resistance Kit is the first in a joint effort by ICE and General Atomic Sciences Education Foundation to bring hands-on materials and physical science to teachers and students. It is available as a teacher demonstration or for hands-on classroom use.
The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts.
Every living creature needs food or energy to survive. Some depend on others for food and energy, whiles others can produce their own food.
Plants make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.
Photosynthesis and respiration go hand in hand. The result of photosynthesis is glucose, which is stored as chemical energy in the plant cells.
This stored chemical energy comes from the conversion of inorganic carbon (carbon dioxide) into organic carbon. Respiration releases the stored chemical energy.
Animals that consume plants also make use of this energy, as do those that consume those that consume plants, and so on to the top of the food chain.
As important a job as making all of the world's food is, there's another vital function that photosynthesis performs: It generates the oxygen that oxygen-breathing animals need to survive.
Students learn about enzyme function, enzyme specificity and the molecular basis of lactose intolerance through experiments with the enzyme lactase and analysis and discussion questions. Students engage in the scientific practices of designing and carrying out experiments and interpreting data. (NGSS)
In this weeks lectures we explored the relationships between living things and energy transfer. In this lab we will more specifically consider the relationships between energy and mass transfer in photosynthetic carbon gain. For the next part of this lab we will utilize the ExPASy (Expert Protein Analysis System) proteomics server of the Swiss Institute of Bioinformatics (SIB). Go to the and search for "Ribulose-bisphosphate carboxylase". From the description answer the following questions:
Hands-On Labs (HOL) is the world leader in distance learning. HOL is changing the way education is conceived, delivered and consumed around the world, regardless of location, time zone, or device. Hands-On Labs produces online science lab kits that include modern pedagogy, cloud-based learning platforms, and hands-on lab experiments that mirror the classroom laboratory.
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.
The leader in this discovery process is your child’s teacher, a LabLearner Teacher. LabLearner Teachers receive special on-site, comprehensive teacher professional development to learn how to use scientific equipment and facilitate the inquiry process for students. Your child’s teacher may have even received graduate-level university credits for online LabLearner courses or for participating in LabLearner Summer Institutes.
Follow in the steps of van Helmont, John Woodward, Joseph Priestley and Jan Ingenhousz and discover photosynthesisIs plant growth affected by exposure to ultraviolet light?
Students investigate the effects of molecule size on diffusion across a synthetic selectively permeable membrane. This investigation includes a brief introduction to osmosis. Additional questions introduce students to the roles of proteins in transporting polar substances across the cell membrane and guide students in analyzing the relative advantages of two different types of model of the cell membrane.

There is no denying the fact that our kids learn better through study aids. And worksheets are great tools for their learning. Today, Shining Mom features some great resources for photosynthesis worksheets you can download and use.
