Driving Question: How can we as 7th grade math students use surface area to make a mug that retains heat for the longest amount of time possible?
This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.
As an analytical chemist at a company developing new engine coolants your task is to determine the heat capacity of a newly developed product and then to determine if its heat capacity is greater of less than that of ethylene glycol.
How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.

Students come to see the exponential trend demonstrated through the changing temperatures measured while heating and cooling a beaker of water. This task is accomplished by first appealing to students' real-life heating and cooling experiences, and by showing an example exponential curve. After reviewing the basic principles of heat transfer, students make predictions about the heating and cooling curves of a beaker of tepid water in different environments. During a simple teacher demonstration/experiment, students gather temperature data while a beaker of tepid water cools in an ice water bath, and while it heats up in a hot water bath. They plot the data to create heating and cooling curves, which are recognized as having exponential trends, verifying Newton's result that the change in a sample's temperature is proportional to the difference between the sample's temperature and the temperature of the environment around it. Students apply and explore how their new knowledge may be applied to real-world engineering applications.
Students will use science skills of observing, describing and measuring in the context of Making Ice Cream. Students will understand the concept that physical properties can change.
Physics I is a first-year physics course which introduces students to classical mechanics. This course has a hands-on focus, and approaches mechanics through take-home experiments. Topics include: kinematics, Newton's laws of motion, universal gravitation, statics, conservation laws, energy, work, momentum, and special relativity.
This course introduces the structure, composition, and physical processes governing the terrestrial planets, including their formation and basic orbital properties. Topics include plate tectonics, earthquakes, seismic waves, rheology, impact cratering, gravity and magnetic fields, heat flux, thermal structure, mantle convection, deep interiors, planetary magnetism, and core dynamics. Suitable for majors and non-majors seeking general background in geophysics and planetary structure.

Developed within Northwest Educational Service District's 2019-20 ClimeTime climate science teacher education proviso grant, this workshop is an opportunity for teachers to gain a better understanding of the physics that drive the climate system and the ocean circulation as well as the implications of a changing climate.
This course is an opportunity for teachers to gain a better understanding of the physics that drive the climate system and the ocean circulation as well as the implications of a changing climate.
The first module encompasses Earth’s radiation balance and the transfer of energy.
The second gives an overview of the ocean circulation, which accomplishes energy (heat) transport. There will be a demo to illustrate the importance of density in the circulation and the vertical structure of the ocean.
The third module discusses the greenhouse effect and global climate change, along with how ocean circulation impacts climate and how a changing climate might impact the ocean circulation.
Lastly, we demo a simple climate model coded in Excel that predicts global mean temperature change.
In this activity, students observe fluid motion and the formation of convection cells as a solution of soap and water is heated. This procedure can be performed as a demonstration by the teacher, or older students can conduct the experiment themselves. A list of materials, instructions, and a description of the convective process are included.
In this hands-on science lesson, the students will observe (and eat!) cooked popcorn and uncooked popcorn. The students will understand why popcorn pops. The students will weigh cooked and uncooked popcorn to understand why cooked popcorn weighs more.
How does energy flow in and out of our atmosphere? Explore how solar and infrared radiation enters and exits the atmosphere with an interactive model. Control the amounts of carbon dioxide and clouds present in the model and learn how these factors can influence global temperature. Record results using snapshots of the model in the virtual lab notebook where you can annotate your observations.
Measure relative humidity in the air using a simple device made of a temperature sensor, a plastic bottle, and some clay. Electronically plot the data you collect on graphs to analyze and learn from it. Experiment with different materials and different room temperatures in order to explore what affects humidity.
Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

Students reinforce their understanding of rocks, the rock cycle, and geotechnical engineering by playing a trivia game. They work in groups to prepare Jeopardy-type trivia questions (answers) and compete against each other to demonstrate their knowledge of rocks and engineering.
With climate change, some parts of the world will get more water, but others will experience droughts. Some will start seeing more mosquitoes, but some fewer. And some regions might actually benefit economically. What’s the deal? In this episode of TILclimate (Today I Learned: Climate), MIT professor Elfatih Eltahir joins host Laur Hesse Fisher to talk about how climate impacts will differ across the globe. Together, they do a quick world tour, exploring how climate change will affect malaria in Africa, water availability in the Nile, and heat waves in Southern Asia.
In Save the Penguins, the broad context is global climate change. Students learn that the energy we use to heat and cool our houses comes from power plants, most of which use fossil fuels to convert chemical energy to electrical energy. The burning of fossil fuels has been linked to increased levels of carbon dioxide in the atmosphere, which in turn has been linked to increases in global temperature. This change in temperature has widespread effects upon life on Earth. Penguins live in the southern hemisphere, primarily on the icy continent of Antarctica. As the Earth warms and ice melts, penguins lose habitat. Therefore, students see that better-designed houses that use less energy for heating and cooling can have an effect on penguins. Energy efficient houses that
minimize unnecessary heat transfer will draw less electricity from the fossil fuel burning power plants and not contribute as much to global climate change.
