Ninth grade Lesson Fission and Chain Reactions
The data shows a numerical relationship to the age of the rocks. Explain how control rods where involved in a chain reaction. Adjust mountain snowfall and temperature to see the glacier grow and shrink. The three different types of unconformities are shown in the textbook refer to the index of the book to find where.
Revisiting Wave Mathematics. In performing these projects, students should have the opportunity to observe change, gather data, record information, and make conclusions about the world around them. Observe and record the exact position of sunrise or sunset weekly for several months. They see that as one U isotope splits three neutron are release with the potential to hit other U isotopes causing the fission reaction to continue. In this activity students are given a map with a view of the Earth as a whole including the seafloor structures.
- Did you find this resource helpful?
- Neutrons are not absorbed and more U splits releasing more neutrons.
- Which of the three types of unconformities is this?
- Or, measure the acidity of local ponds.
This means that the remains of living things are useful for carbon dating. At the end of the lab, give them the opportunity to revisit these questions and change or justify their answers. If they haven't changed their answers, ask them to explain why. Also, return to the questions you asked in the introduction to the lesson and allow students to revise their answers.
This activity does not address any continental shapes, seafloor structures or plate motions. They do the multiplication of time by speed themselves and so may adjust the speed depending on distance, for example. Below, 100 percent free you will find a small selection from the Smart Science library of nearly online science labs. Equal aliquots of water are added.
Are you using free Virtual Lab materials you found on the web in your teaching or your learning? Have you posted free Virtual Labs online that are open for others to use? Understand how decay and half life work to enable radiometric dating. Another numerical relationship is having the students use a method called radiometric dating to calculate the absolute age of the rock.

They classify each sample. What happens when you add clouds? Demonstrate how much energy you can collect, or use the energy for some useful purpose, such as cooking something or heating water. We know that radioactive substances disintegrate at a known rate, however.
Details and get access to Glaciers Check out Glaciers. Students can place pins on a map to identify geologically active zones of the Earth. At the end of the simulation students are asked to summarize the key facts of the investigation in their journals. Other aspects of water erosion may be considered as well.

By this point in the unit students have had enough practice working on alpha and beta decay problems that most do not have questions. What was the difference between u and U? Science and Engineering Practices. You need not agree with arguments on the other side, but you should consider their merit.
The project should involve doing science, not just writing about science. Advise students to read through the simulation first so that they understand what they should do. Correlate changes with rainfall or other factors.
Students can supplement this site with a visit to Isotopes Project. When it comes to nuclear chemistry, dating simulations are a very effective way for students to visualize what otherwise would not be possible in a chemistry classroom. Have students look at the Glossary of Nuclear Science Terms for alpha and beta decay. Details and get access to Porosity Check out Porosity.
Students measure the height of water after each addition and calculate porosity of each medium. You may want to construct your own surveying instruments. Details and get access to Earthquakes Check out Earthquakes.
- Details and get access to Gravity and Orbits Check out Gravity and Orbits Glaciers Adjust mountain snowfall and temperature to see the glacier grow and shrink.
- Discover how to create new mountains, volcanoes, or oceans!
- Be sure that your model is to specified scale s.
Measure the maximum height of the tides at a nearby location for a month. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. Write about how the strontium might accumulate in your body teeth and bones and how it might affect you. Details and get access to Plate Tectonics Check out Plate Tectonics Gravity and Orbits Move the sun, earth, dating services that are free moon and space station to see how it affects their gravitational forces and orbital paths.
Some projects will require data collected over a number of months. The only materials that start out with usable amounts of carbon in them are carbon-bearing materials which derived their carbon immediately from the atmosphere or from shallow water. The mathematics of inferring backwards from measurements to age is not appropriate for most students. Sample sediments being deposited in the same place in an active stream or lake for several months. For the students that are still struggling I provide them with another practice decay series with one-on-one help to move them past their difficulties.
Lab 7 - Lab Report Lab Report 7 Atomic Dating Using
Prepare a display to highlight a local pollution problem. Students should complete the Analysis section of the lab sheet, which will be used as part of their assessment. Strata are layers of rock. Suppose we have nuclei of a radioactive isotope. Measure and record the rate of erosion of a hill slope, road-cut, or another unstable land feature.
You may group them in any size, but working in pairs is optimal for this exercise. This is a good opportunity to show your skills in drawing isolines. Correlate changes with weather conditions, storms, human activities, etc. Your teacher can help you in identifying the samples. This provides me with immediate feedback which I will use to begin the next class periods conversation about fission.
Measure stream discharge daily or weekly. Explore how plates move on the surface of the earth. Visit this site for more information about strontium and about the nuclear accident in Chernobyl in and its aftermath.
Construct a solar energy collector. The daughter products and neutrons fly apart with energy. Construct a scale model of the solar system in three dimensions. Analyze and interpret data to provide evidence for phenomena. Where in your environment might scientists look for large concentrations of strontium?
Use a thermometer to record the air and water temperatures in a pond or stream. Patterns in rates of change and other numerical relationships can provide information about natural systems. The display should be presented in a public area. Correlate your data with changes in the speed of the water.
This process will help students develop an understanding that energy is released during fission. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! Word processors, computers, and still or video cameras can add to the value of your report. Remember to put your name on your exercise pages, not just the outside of the envelope. Students record channel width for water flow on a sand-filled stream table for different flow rates and slope angles.
