Skills Workshop
Ratio, Scale, and Proportion
Converting units is an excellent example of how math relates to our everyday tasks. The resource prompts mathematicians to use baking, cooking, and other daily activities to discover how to make larger quantities of each ratio or recipe.
Houston Area Calculus Teachers
Area and Volume
An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created from the...
Curated OER
The Same, But Different Part II
Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...
Curated OER
Using Your Marbles - Volume Measurement and Reporting
Demonstrate how to measure the volume of liquids and solids immersed in liquid to your class. They observe a teacher-led demonstration, and in small groups construct a data table that demonstrates how many marbles were used and the...
Beyond Benign
SLS Toxicology Test
Ingredients in your shampoo are toxic enough to kill plants. The 16th installment of the series of 24 tests the toxicity level of various concentrations of SLS, a chemical found in nearly all shampoo. Learners prepare percent solutions...
Curated OER
Examine Methods of Reporting Research Results
Students analyze a research report and the list of components needed in a research report and then identify those components based on a set of standards using the scientific method. They collect data which can be used for a graphical...
Curated OER
The Blue Bottle: An Example of Teacher-Guided Inquiry
High schoolers observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.
Curated OER
Calculating Errors of Measurement
In this errors in measurement worksheet, students answer four questions to show their understanding of errors when taking scientific measurements. They determine the percent error in each problem.
Curated OER
Making Hail
Fourth graders investigate the different types of precipitation and conduct a hail experiment. They identify the types of precipitation during a slideshow, and define key vocabulary terms. Next, in small groups they follow the...
Curated OER
Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Practice with Mass
Fourth graders investigate the weight/mass of a number of items using grams, and equivalents. They examine the use of a triple beam balance before massing objects including oil and water. They go over the weights they amassed and weigh...
Curated OER
Bathtub Physics - Density, Buoyancy and Flotation
Students study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.
Curated OER
"Pandemic" A Disease Simulation
Students use small test tubes with water, salt and a silver nitrate solution to simulate the spread of infectious disease contracted the exchange of bodily fluid. They problem solve to track the original source of infection.
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Enzymatic Reaction
Students explore the effect enzymes have on reactions. They demonstrate the process of enzymatic reaction by making cheese. after experimentation, they answer a series of questions.
Curated OER
The Same but Different Part II
Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...
Curated OER
The Same But Different
Third graders observe a frozen container filled with ice and discuss what happens when the ice sits out in the room. They practice measuring the mass and volume of the ice, watch as the frozen container is placed in a warm water bath to...
Curated OER
The Same But Different
Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...
