Bacterial growth
Young scholars explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.
Curated OER
Hot Cans and Cold Cans
Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

Our Desert Backyard
Students make observations of their own backyard. In this environment activity, students keep records of the plants and animals they see in their home or school yard. Students make notes of how the weather and environment changes over...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Keep it Bottled Up: Linear Rates of Pressure Increase
Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...
Curated OER
Enzyme Lab
High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...
Curated OER
Air Pressure & Barometers
Fourth graders observe, measure, and record data on the basic elements of weather over a period of time (i.e., precipitation, air temperature, wind speed and direction, and air pressure). Then, they make a barometer and keep record of...
Curated OER
Carbon Dioxide Heats It Up
Students design an investigation to test whether vegetation in an area helps regulate the ambient air temperature. They make comparisons between the investigation and global changes in climate. In groups, they present their findings to...
Curated OER
Hot Friction
Sixth graders use small electronic devices known as thermistors to measure the temperature beneath an object such as a coffee cup as it slides across a surface. By choosing different surfaces, 6th graders can compare in a quantitative...
Curated OER
Warm Me Up!
Third graders explore and identify heat sources. They conduct an experiment involving thermometers and articles of clothing, and record and discuss the results.
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry instructional activity, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.
Curated OER
Global Change — Change and Cycles Where Land, Air and Water Meet
Learners participate in an experiment to define a parts-per-billion solution. In this ecology lesson plan, students select a second substance to create a parts-per-billion solution and observe and record their results. Learners work in...
Curated OER
Permafrost: Permanently Frozen Ground
Students explore permafrost. In this 3 states of matter lesson, students identify characteristics of solids and liquids. Students observe water and soil melting and freezing at various temperatures. Students make...
Curated OER
Get to know H2O!
Students investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.
Curated OER
Arctic Microclimates
Students identify, measure, and average micro-climatic temperatures in a particular region. They draw a small-scale map of an area to be sampled (classroom, playground, park, backyard) and identify potential locations for...
Curated OER
Solid Water
Students turn solid water (ice) into liquid water. In this solid and liquid water lesson plan, students use water, ice, cups, and heat in order to change water from one state to another. They draw their findings as well.
Curated OER
Bounce Back Ball
Fifth graders work in teams of four to measure the rebound heights of a tennis ball dropped from four different heights. They investigate with the bouncing balls to measure changes in the type of energy they possess.
Curated OER
Transforming Food Energy: A Balancing Act
Students explain their role as consumers. They use a purchased calorimeter or make their own simple calorimeter to measure the energy content in selected foods. This interesting lesson really gets students thinking about what they eat.
Curated OER
Climate and Weather
Students become familiar with weather terminology and different representations of data as they explore various on-line weather sites. They practice using and interpreting data determining the effects of the time of day, time of year and...
