Cloning And b-Galactosidase

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

Students examine how living cells reproduce to make new cells.  In this cell reproduction lesson students complete a lab activity and answer questions. 

Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...

Even today's stem cells have a history—and it's more than 30 years old! Learn how stem cell lines grow in a lab. Observe the various experiments completed to determine how cells grow in human embryos.

Variety truly is the spice of life. A video explores how plants have both chlorophyll a and b and the benefits of possessing both, how varying molecules allows for winter wheat, how possessing the heterozygous combination of sickle-cell...

View this video/animation to see how one type of immune cell-the helper T cell-interprets a message presented at the surface of the cell membrane. The message is an antigen, a protein fragment taken from an invading microbe. A series of...

Students explain how cells reproduce. In this biology lesson, students explain the different stages of the cell cycle. They calculate the number of new cells produced.

Students participate in an extended laboratory research to experience how scientific information is obtained, upon which we build scientific knowledge and understanding.

In this cloning worksheet, high schoolers will read a paragraph about how cloning has been a benefit to medicine and agriculture. Students will underline the main idea in the paragraph and write down three supporting details. Then high...
