Students use various snacks to make large models of human cells. Items such as gumballs, gummy worms, and jelly beans represent the nucleus, golgi bodies, and mitochondria. As each piece of candy is added, the teacher explains what it...

In this atoms learning exercise, learners review terms associated with atoms which includes isotopes, transmutation, and radioactive decay. This learning exercise has 11 short answer questions.

Students investigate the importance of sexual reproduction in evolution. For this sexual reproduction lesson plan, students simulate species with two traits: eye and skin color. They determine what characteristics are beneficial for the...

For this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom....

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

Students discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a microscope.

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

High schoolers use the Internet to research the history of the splitting of the atom. They use that research to prepare a presentation on an aspect of that topic. A map is generated to record findings and results.

Using the periodic table of elements, young chemists fill in a chart of isotopes to show the atomic number, mass, charge, number of protons, number of neutrons, and number of electrons. The chart is followed by 11 questions that...

Tic-Tac-Toe is a game most students will be familiar with. This fun activity prompts students to answer questions about cells organelles in order to place a mark on the grid. There are some non-essential humorous sound effects and...

In this protein synthesis worksheet, students answer 14 short answer questions about the process of making proteins from DNA.

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Students investigate the cycle of mitosis. In this biology instructional activity, students discuss the different stages of mitosis through cell reproduction. They further their investigation through laboratory analysis.

Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

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.

First year physics learners show what they know about electric potential, circuits, power, current, and voltage on this midterm exam. It consists of a multiple choice section, some true or false questions, and two multi-step problems to...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

This multiple-choice and short-answer quiz covers chromosomes, genetic disorders, and more. The multiple choice section could work as a pretest, as well.

In this Geiger counter instructional activity, students read how Wilhelm Geiger developed a device that detects radiation detection. Then students will complete 2 short answer questions.

Students define vocabulary related to the parts of the atom.  In this matter lesson, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with positive and...

For this atom worksheet, students fill in three charts using the periodic table to identify atomic number, atomic mass, number of subatomic particles and the element's symbols. Students draw an atom and it's subatomic particles as well...
