1 – 16 of 16 Classroom Resources

• Dimensional Analysis, Measurements | High School, Middle School

### Animation: Measurement

In this animation, students will become familiar with three forms of measurement, including length, mass and volume. Various units of measurement will be presented for comparison, and several conversion calculations will be demonstrated using dimensional analysis.

• Observations, Physical Properties, Chemical Change, Physical Change, Dimensional Analysis, Measurements, Matter, Mixture, Chemical Properties | High School, Middle School

### Activity: Cupcake Conversions, Bench to Bakery

This activity will help to reinforce the importance of scientific measurement and apply it to the introduction of chemical reactions. Using an example of baking a single batch of cupcakes, students will plan for a larger production scale in a commercial bakery. This will help to introduce the idea of producing a reaction at the lab bench and converting it to mass production. In addition this activity investigates how chemistry is used in everyday life and challenges students to consider potentials errors that may occur when completing chemical reactions in the kitchen.

• Physical Change, Dimensional Analysis, Measurements, Matter, Mixture | High School, Middle School

### Activity: Cooking with Conversions

In this activity, students will be given a common homemade recipe for German chocolate cake with measurements in English units. They will be asked to convert the English ingredients list to metric units through scientific calculations. Students will also be asked to identify the ingredients as solid, liquid or gas. While reviewing the cooking procedures, students will classify certain steps as containing compounds or mixtures as well as identify whether chemical or physical changes are taking place. The culinary chemistry involved in this lesson should be introduced throughout the activity.

• Density, Identifying an Unknown, Measurements | Middle School, Elementary School

### Demonstration: Household Densities

In this demonstration, students will make predictions about various household materials and whether or not each will sink or float when placed in water. Data will be collected and then used to calculate the density value of each item. Finally students will analyze the relationship between the density value and the observed outcome, and use their knowledge to identify unknown materials.

• Review, Dimensional Analysis, Measurements | High School, Middle School

### Activity: Dimensional Analysis Show Down

In this activity students will work cooperatively to solve conversion based problems using dimensional analysis. Students are required to independently determine an answer for each question and be able explain their method of solving with their peers. This activity is designed to allow students to work at their own pace, and for students to take on a teaching role by communicating their understanding with their peers.

• Observations, History, Conservation of Mass, Measurements, SI Units | High School, Middle School

### Activity: Lavoisier Video Questions

In this activity, students will watch a video about Antoine Lavoisier, who many consider to be the father of modern chemistry. They will answer questions as they learn about oxygen, hydrogen, and the first proposal of the Law of the Conservation of Mass.

• Physical Properties, History, Measurements, Temperature, SI Units, Accuracy | High School, Middle School, Elementary School

### Activity: Temperature Guys Video Questions

In this activity, students will watch a video and answer questions about how both the thermometer and the concept of temperature evolved over time

• Conservation of Mass, Measurements | High School, Middle School

### Lab: Mass of a Gas

In this lab, students will perform a simple chemical reaction in a closed system to produce a small amount of gas. They will collect mass measurements for the reactants and the products in order to demonstrate the conservation of mass during the reaction. They will also release the produced gas from the closed system in order to verify that gasses have mass.

• Observations, Density, Measurements | High School, Middle School

### Lab: Penny Boats

In this lab, students will explore Archimedes’ Principle and how it relates to density. Each student will be given a piece of aluminum foil and asked to design and build a boat that will hold as many pennies as possible without sinking when placed in water.

• Accuracy, Measurements, Significant Figures, SI Units | High School, Middle School

### Simulation: Measuring Volume

In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.

• Density, Measurements | Middle School, Elementary School

### Lab: Weight Just a Minute!

In this lab, students will learn how volume and mass affect density as they make comparisons and calculations.

• Mixtures, Interdisciplinary, Concentration, Measurements, Scientific Method | High School, Middle School

### Lab: Effect of Salt Concentration on Plants

In this lab, students will observe how salt concentration can affect the structure of a potato tuber.

• Density, Accuracy, Measurements, Significant Figures | High School, Middle School

### Lab: Significant Figures and Lab Data

In this lesson, students will use laboratory equipment of different precision to collect data for several different metals, and then use the data to calculate the density of each. They will then compare their calculated densities to accepted values and determine the combination of equipment that leads to the most accurate calculation of density.

• Density, Physical Properties, Measurements, Matter | High School, Middle School, Elementary School

### Animation: Density Animation

"In this animation, students will visualize density on the particulate level. There are opportunities to make qualitative and quantitative comparisons between substances. **This video has no audio**"

• Observations, History, Conservation of Mass, Measurements, SI Units | High School, Middle School, Elementary School

### Video: Antoine Lavoisier Video

This video tells the story of Antoine Lavoisier who many consider to be the father or modern chemistry. Lavoisier discovered oxygen and hydrogen and first proposed the Law of Conservation of Mass.

• Conservation of Mass, Conservation of Mass, Measurements | Middle School, High School

### Lab: Mass & Change

In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
