In this comparing plant cells and animal cells activity, students view cells from their cheeks and cells from elodea. A Venn diagram reveals similarities and differences between the cells.

Young scholars examine water. For this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...

Learners write the electron configuration of elements in the ground state. In this chemistry instructional activity, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Students become familiarized with use of the microscope.

Students participate in a lab activity in which they extract DNA from a strawberry. After mashing the strawberry into an even, smooth puree inside a bag, they add extraction buffer and mix the strawberry with the buffer. They filter...

In this chemistry instructional activity, students complete 29 fill in the bank questions about atoms based on the movie Exploring Atoms from the website www.brainpop.com .

In this elements instructional activity, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This instructional activity has 20 short...

Students extract the DNA from a strawberry. In this DNA technology instructional activity, students describe what they think DNA looks like. They use a procedure to isolate and extract the DNA from a strawberry.

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative activity students describe the contributions that scientists have helped develop the atomic theory and identify...

Students explore the names and qualities about members in the group. They each say their name and something about themselves. Students gather around in a circle. They listen to the teacher as he or she says the name of someone and throws...

Students study amino acids and discover the different proteins that are in our bodies.  In this living environment lesson students build protein bracelets with beads as an example of the different amino acids. 

Students investigate Mendelian Genetics by studying the history of Mendel and what it was like to be a 19th century scientist. They read a pieces of fiction during this investigation.

Students examine the process of protein synthesis. In small groups, they select an index card, and translate the DNA to an amino acid, and define the words on an anticodon/amino acid chart.

For this nuclear power worksheet, learners compare fission and fusion. Students learn about the different kinds of radiation. This worksheet has 2 short answer questions and 10 matching questions.

For this physical vs. chemical change worksheet, students answer 10 questions about identifying chemical and physical changes. They identify exothermic and endothermic reactions and the parts of a chemical equation. Students answer 1...

Young scholars use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

Students create technology based portfolios for others to use as a pattern for assessment. They make a "Personal Autobiography Page" to start the portfolio.

Pupils review the structure and fuctions of plant and animal cells. They use various types of materials such as sugar cookies and cake frosting for this lesson.

Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...

In this science activity, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.

For this DNA: structure and replication worksheet, students fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.
