Curated OER
Causal Patterns in Density Phenomena
Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...
Curated OER
Let the Sunshine in
Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...
Curated OER
Cell physiology and chemistry
Students design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
Detecting Disease
In this detecting disease worksheet, students will review the different tools scientists use to identify diseases including the steps of Koch's postulates. This worksheet has 14 fill in the blank and 4 short answer questions.
Curated OER
Structure of Matter
In this science puzzle worksheet, learners solve a crossword puzzle related to matter. For example, "Scientist who discovered protons."
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
Flame Test
Students conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.
Curated OER
Pauli's Magical Water
Learners 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
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
Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
Curated OER
Automated Vehicle Programming Design
Students design a program to make an automated vehicle perform a specific task. In this robotics lesson, students play the role of scientists competing to win a factory's contract. They present their algorithm to class.
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
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
The Physical Setting
Students study atoms and their protons and neutrons. In this physical setting lesson students work together to complete a lab activity.
Curated OER
How Can You Study Things You Can’t See Like: Atoms?
Students simulate how scientists studied things they can't see like atoms. For this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.
