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...
Curated OER
Lizard Lab
For this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection.
Texas State Energy Conservation Office
Investigation: Splitting Atoms
In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...
Curated OER
Isotopes of Pennies
Learners demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.
Curated OER
Radiation
Students distinguish between natural and man-made radiation. They measure radiation using a Geiger counter and investigate footprints of radiation.
Curated OER
Math 155 - Worksheet 10. Logarithm
In this logarithm worksheet, students read story problems, write an equation to solve the problem, and leave the answer in logarithm or exponential form. They find the derivative of given functions. This two-page worksheet contains six...
Curated OER
Determining Age Of Rocks And Fossils
Young scholars discuss together how to determine the relative age of each of the rock units in the block diagram (Figure 1). After students have decided how to establish the relative age of each rock unit, they should list them under the...
Curated OER
Thermal Waters & Geologic Provinces
Students investigate thermal waters and geologic provinces. They examine provided maps of geothermal springs and thermal wells in the state of Idaho and their locations relative to Idaho's geologic provinces. Afterward, they use the maps...
Curated OER
Volcanoes
Students study volcanoes. In this volcanoes activity, students read several volcano paragraphs and study the pictures or diagrams. Students then make an erupting volcano, complete website research about volcanoes, and answer several...
Curated OER
What is the Rock Cycle?
Students investigate the rock cycle. For this geology lesson, students read about the rock cycle on a website and discuss the steps of the rock cycle. Students visit a rock cycle website to complete a quiz. This is the first introductory...
Curated OER
Volcanic Violence
In this volcanic violence worksheet, students interactively answer 5 multiple choice questions, then click to find answers and explanations.
Curated OER
Development of the Atomic Theory
In this atomic theory worksheet, high schoolers complete a paragraph describing the development of the atomic theory by filling in the blank with 21 terms.
Curated OER
The Noble Gases
When breaking down the details of the periodic table of elements, this presentation will explain special characteristics for each of the noble gases. The annotations are quite elementary, so this can easily be used in an introductory...
Curated OER
Plate Tectonics
Learners research separate elements of the theory of Plate Tectonics, then share that information with each other, drawing conclusions from the culminated information.
Curated OER
Connection to Fine Arts: Carbon-Dating Masterpieces
In this carbon dating worksheet, students read about how carbon-14 is used to date historical paintings. They answer questions about carbon dating and its importance.
Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
What is Radon?
Students read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.
