Curated OER
Radioactive Decay
Students generate a radioactive decay table for an imaginary element, use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.
Curated OER
Activity One -- Fundamentally Speaking
In this science learning exercise, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.
Curated OER
The Water Cycle and Global Warming
Learners study the flow of water in the environment. In this water cycle lesson students evaluate the consequences of changes in the water cycle using data.
Curated OER
Pauli's Magical Water
Pupils predict the shape of molecules using VSEPR theory. For this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
Curated OER
Causal Patterns in Density Phenomena
Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
Curated OER
Classifying Matter Game
Students identify the different states of matter. For this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.
Curated OER
Physical and Chemical Changes
Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.
Curated OER
Using several learning modalities to teach about the Periodic Table.
Pupils identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also, alkaline...
Curated OER
Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. In this physics instructional activity, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
Curated OER
Reading Labels For Fat Types
Students analyze a variety of cooking oils to determine the amount and types of fats included in each.
Curated OER
Quantum Mechanics and Atomic Physics
Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.
Curated OER
Grating Spectrometer
Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
Curated OER
Code Makers - Electron Configuration, Aufbau Principle
Learners write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.
Curated OER
Static Cling
Young scholars work together to discover the concept of static electricity. They participate in an experiment in which they test different objects charge. They make observations and record them for later use.
Curated OER
Compounds and Molecules
In this compounds worksheet, high schoolers compare separating elements of a compound and substances in a mixture. Students review melting and boiling point. This worksheet has 1 fill in the blank and 5 short answer questions.
Curated OER
Radioactive Decay/Half Life
Students demonstrate radioactive decay using candy corns. In this Physics lesson, students make predictions, collect data and form conclusions about patterns in radioactive decay.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
Quantum Physics
Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
Curated OER
Science Puzzle
In this science worksheet, students identify and locate vocabulary words related to various sciences. There are 20 words located in the word search.
Curated OER
Spectroscopy Demonstrations
Young scholars study light and see what emits photons and that light can be separated onto a spectrum. In this energy and matter lesson students identify gases using a spectrum chart.
