Types of Decay
The types of decay, and why they occur within an atom, are the focus of this chemistry video. Sal covers the basic ways that a nucleus of an atom can decay. He gives examples of beta decay, alpha decay, gamma decay, and positron emission.
Young scholars investigate what is inside three different boxes using indirect observations and relate it to the discovery of the structure of the atom. In this atomic structure lesson plan, students explore the history of atomic structure by experimenting with indirect observations of 3 boxes and testing Rutherford's equation using a box and marbles. Young scholars discuss Rutherford's experiment to determine the size of the nucleus of an atom.
What a comprehensive summary of introductory nuclear physics! Although the delivery is dry, the information is valuable and several "Check for Understanding" slides are interspersed throughout to reinforce learning. As a result of viewing these slides, future physicists will be able to determine the charge of a nucleus, differentiate between alpha and beta particles, describe background radiation and Geiger counters, and more! These 90 slides can provide support for an entire nuclear energy unit for your high school physics class.
What's the Matter? Locating Electrons in an Atom
Learners roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.
What is Matter?
Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons, the nucleus and quarks.
Temple 1-Close-Up of a Comet!
In this comet worksheet, students solve 3 problems using a composite image of the Temple 1 comet. Students determine the scale image, the size of the nucleus of the comet and the height of a cliff on the comet.
Quantum Leap Lab-Probability and Electron Structure
High schoolers use a marble and a bull's eye target sheet to simulate electrons and the nucleus of an atom. In this probability and electron structure lesson plan, students investigate the location of electrons in atoms by using target sheets to drop marbles from knee level and eye level onto the sheet. High schoolers tally the location each marble lands in and they answer 5 questions about probability and the location of electrons in atoms.
Atomic Structure and Bonding
Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different amounts of protons. Students examine the Bohr Model through lecture. Students build their own atomic models with materials provided in the classroom.
Radioactivity-What is the Nucleus Like?
In this radioactivity activity, students answer 40 questions about half life, isotopes, radioactive decay, the uses of radioactivity, nuclear equations and the scientists associated with radioactivity.
Comets and Meteors
Students construct a model of a comet nucleus using dry ice. They add other materials and describe the features. They complete related exercises on an Internet Web site.
What is the Nucleus Like?
In this nucleus of an atom worksheet, learners answer 19 multiple choice questions about the structure of the atom, radioactive decay, isotopes and half life.
DNA and Individual Differences
Students list differences between DNA-related terms and create a simple DNA circle map. They order terms including human body, organ, tissue, cell, nucleus, etc. from largest to smallest. They discuss differences and similarities among members of their class.
A Lesson on Genes: Monster Mash for Grade 9
Ninth graders examine dominant and recessive gene through this activity that uses paper bags filled with upper and lower cases letter which represent a cell nucleus and the genes within it. They design a monster drawing based on the genetic traits that are paired in the bag. They complete a Punnett square with the genetic material.
Those Cells Look Good Enough to Eat
Students explore the parts of the cell. In this cell instructional activity, students use foods to create cell models that represent the nucleus, cytoplasm, cell membrane, mitochondria, ribosomes, vacuoles, endoplasmic reticulum, and Golgi bodies Students also include the cell wall and chloroplasts which only apply to plant cells.
How do protons stick together in a nucleus?
Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.
Students model the removal of a cell nucleus and the insertion of an alternate control center. They define some of the challenges faced in this type of transplant procedure. Students discuss cloning.
Cells and Cancer
Young scholars idenitfy that cancer is a growth of mutated cells and that cancer cells are only one type of cell that causes disease in our body. They also identify that all eukaryotic cells contain a nucleus, cytoskeleton, and a cell membrane. Finally, students create models of a normal and cancerous cell using a handout included in the lesson.
Phases of Mitosis
The lecturer starts by emphasizing that the mitotic process is a separate mechanism to cytokinesis - the cytoplasm splitting to become 2 cells. The video continues explaining the stages of mitosis in great detail. Each stage is diagrammed and the relevant structures are labeled and explained. Your students will find this to be a valuable supplemental study tool.
Nuclear Reactions - Rutherford's Alpha Scattering Experiment
Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this presentation uses a series of diagrams to show how some particles fly through the foil while others bounce back. You will definitely want to add this to your lesson on atomic structure!
Atomic Musical Chairs
An engaging activity enlightens young chemists in this instructional activity on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and neutrons. Oh what fun!
