In this DNA worksheet, students read information about DNA and messenger RNA. Then students complete 16 short answer questions and color 2 images.

For this atoms crossword puzzle, students read 15 questions about atoms and fit the answers into a crossword. This difficult puzzle has no word bank.

Students define attributes of human chromosomes and match them to make a human karyotype.  In this investigative lesson students demonstrate how traits are encoded in genes found on chromosomes. 

Students examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

In this grade 6 science quiz, 6th graders complete a 15 question multiple choice quiz covering a variety of grade 6 concepts. 

Fourth graders create analogies in poster format between a cell's organelles and their school. For example, 4th graders coul say a cell's mitochondria is like the cafeteria, both are a source of energy.

Students work together to identify the structure of DNA. They practice using new vocabulary as well. They create a 3-D model of DNA to complete the lesson plan.

Students investigate cloning using E coli cultures. Through laboratory exercise, they determine if E coli cells contain b - galactosidase.

Students explore the structure of a plant cell. They carefully peel a single layer of onion skin from a slice of onion and stain it with methylene blue to observe the structures inside. They use a Digiscope connected to a computer to...

In this making atoms science activity, students read about the atomic number of protons, finding the number of neurons, and how electrons function before they complete the atom board graphic organizer and respond to 4 short answer...

In this cells worksheet, students compare the characteristics of eukaryotic and prokaryotic cells. Students describe how different scientists contributed to the cell theory. This worksheet has 6 short answer questions and 1 graphic...

In this science crossword puzzle worksheet, learners determine the answers to 7 clues using vocabulary associated with atoms and matter. They fill in the puzzle both across and down.

Eighth graders use a large Punnett Square and infer how genes determine blood types.  In this blood type lesson students predict blood types and demonstrate how Punnett Squares are related to genes and chromosomes. 

Students investigate vocabulary words associated with electricity.  In this electrical lesson, students utilize the Internet to research what electricity is and how it works.  Students create an actual circuit in class using a...

Students study magnetism. For this science lesson, students participate in an activity to discover how electrons in a magnet move. Students identify items around the classroom that are magnetic.

Students explain concepts related to static electricity, based on a single example: lightning.

Students reinforce the concept that static electricity is a phenomenon that involves positive and negative charges.

Students become familiarized with use of the microscope.

Students explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

Fifth graders, in groups, create a plant or animal cell out of cookies, frosting, and candy pieces.

Fourth graders draw on previous knowledge and create hand-held flip books that show a cell going through the motions of the cell cycle. They create a flip book, which illustrates the cell cycle.

Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Seventh graders examine the functions and roles of membranes in cells. They discover the differences between plant and animal cells.

Students examine the cytoskeleton of a cell. They work together to build a structure with a certain number of materials. They share their "cell" with their classmates.
