Plan a live demonstration for your teacher. Have you tried this lesson? Students will create a model and explain it to their peers with their moveable continental plates.
Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Also, return to the questions you asked in the introduction to the lesson and allow students to revise their answers. Have students write their answers to these questions in their science journals.
The data shows a numerical relationship to the age of the rocks. Take weather readings daily. Analyze and interpret data to provide evidence for phenomena.
Distinguish different types of unconformities in the stratigraphy of the Grand Canyon. Study this diagram carefully, noting the orientation of individual rock layers, as well as the type of rock in each layer, and the age of the rock in each layer. They do the multiplication of time by speed themselves and so may adjust the speed depending on distance, for example.
In the sequence of geological eons, eras, or periods, where is the unconformity located? Where in your environment might scientists look for large concentrations of strontium? The unstable U eventually breaks apart into two daughter products and three neutrons. Refer to the geologic time scale on page for the names of each of the geologic time periods, as well as the absolute dates attached to each Period.
- They then plot circles around the seismograph locations on a map to find the approximate epicenter.
- Write about how the strontium might accumulate in your body teeth and bones and how it might affect you.
- The mathematics of inferring backwards from measurements to age is not appropriate for most students.
- This lesson can be done in two, minute class periods.
- Erosion may be correlated with rainfall, human activity, etc.
In order to answer the following questions, you will need additional geologic information about the Grand Canyon. Scientists are rarely able to perform an experiment and obtain meaningful results within a time frame of one or two class periods. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. Classify your samples and tell about how they formed. Your display could include photographs, newspaper reports, christian dating sites france and samples of pollution.

Which of the three types of unconformities is this? This activity does not address any water patterns in each of the simulated dig sites and the ancient land would relate loosely to the layers in the simulated dig site. Smart Science real online science labs provide instructors and students with uniquely hands-on real lab experiments instead of simulations. In performing these projects, students should have the opportunity to observe change, gather data, record information, and make conclusions about the world around them.
Ninth grade Lesson Fission and Chain Reactions
The following investigations require an extended period of time. Ask students to explain the terms in their own words. Then compare to the effect of glass panes. Construct a solar energy collector.
After students have completed the activity, discuss the answers to the analysis questions with the whole class. Investigate the latitude, simple dating longitude and depths of earthquake foci obtained from current data. It is the length of time required for the disintegration of one-half of a given number of nuclei of a radioactive element.
You may want to construct your own surveying instruments. Students record channel width for water flow on a sand-filled stream table for different flow rates and slope angles. Adjust mountain snowfall and temperature to see the glacier grow and shrink. Make a contour map of the area around your home.
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? Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Every time an isotope of U is split energy is released, this energy need to be controlled otherwise a meltdown will occur. Students measure the height of water after each addition and calculate porosity of each medium. Note that the first four answers are already given to you. After this simulation have the students complete a lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions.

Correlate changes to changes in wind direction and other factors. Details and get access to Porosity Check out Porosity. Your colleagues and students around the world will thank you! You may group them in any size, but working in pairs is optimal for this exercise. View the above image, 20 something dating a cross-section side-view of a cut-out through the crust of the Grand Canyon.
For additional contact information and to learn more about Smart Science, see this announcement. Visit this site for more information about strontium and about the nuclear accident in Chernobyl in and its aftermath. Only the distribution of fossils and rocks, the age of rock layers and the Law of Superposition are addressed in this activity. Construct a scale model of the solar system in three dimensions. 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.
Virtual Courseware Labs
Do something small, but do it very well. In this activity students are given a map with a view of the Earth as a whole including the seafloor structures. Measure the acidity of rainfall in different weather systems. Student see twelve rock samples, three each of igneous, metamorphic, and sedimentary, rotated, scratching glass and brass, transport and up close. Correlate changes with rainfall or other factors.
Word processors, computers, and still or video cameras can add to the value of your report. Details and get access to Plate Tectonics Check out Plate Tectonics Gravity and Orbits Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Explain how control rods where involved in a chain reaction.
- This process will help students develop an understanding that energy is released during fission.
- Many students struggle with graphing, so I allow them to take a picture of the decay series and graph in order to check for accuracy in a more efficient manner outside of class.
- Measure the maximum height of the tides at a nearby location for a month.
- Let's begin with a small number.
