Get on the Stick (Biology Applications)
Students use a motion detector to the measure the reaction time of other students. They graph the data from trials conducted in the class and analyze trends. They then calculate drop distance from reaction time.
Please Re-Leaf Me
In this activity, students examine data of carbon dioxide output in a forest. They graph the data and understand seasonal flucuations of carbon dioxide output. They make predictions about carbon dioxide output in other biomes.
In this activity, students examine the size, mass, and growth rates for three species of fish. They interpolate and extrapolate from best-fit models. Students compare the growth rates of endothermic and exothermic animals.
Variety is the Spice of Life
In this activity, students will collect data on all members of the class. They will make a graph of the data collected, interpret variations, and then draw conclusions.
Vernier - Enzyme Action: Testing Catalase Activity
Students will use an O2 Gas Sensor to measure the amount of O2 produced when H2O2 is broken down by the enzyme catalase at different concentrations, pH values, and temperatures. They will also measure the enzyme's initial reaction rates.
Vernier - Photosynthesis
Students will use a Colorimeter to compare the rates of photosynthesis for plants in different light conditions. They investigate the role of chloroplasts and light on photosynthesis.
Vernier - Photosynthesis and Respiration
Students use the gas sensors to measure the amounts of oxygen and carbon dioxide consumed or produced by a plant during respiration and photosynthesis. They also determine the rate of respiration and photosynthesis in a plant.
Science TODAY™ - Growing Bigger by the Decade
Students will examine the current and predicted population data from the countries included in the USA TODAY Snapshot® "Growing bigger by the
Science TODAY™ - Breast Cancer Risks
The USA TODAY Snapshot® "Breast Cancer Risks" shows the percentage of women in several age categories that, statistically, develop breast cancer. In this activity, students will calculate the overall percent chance that a woman has of being diagnosed with breast cancer.
Science TODAY™ - West Nile Killing More People
After studying the USA TODAY Snapshot® "West Nile Killing More People," students will compare the number of West Nile cases in the United States over the past three years.
Science TODAY™ - The USA's Expanding Weight Problem
This activity reveals the incidence of obesity in the United States. Students will analyze "The USA's expanding weight problem" and other data to construct a graph, analyze the trends in the data, and make predictions about the future.
Call it ...Dominant or Recessive
In this activity, students simulate a Punnett square of a cross between two heterozygous individuals and produce a histogram. They compare actual and expected results of genetic crosses.
Use the SciTools App to simulate a Punnett square. Make predictions about genetic crosses. Learn about the following concepts; genes, alleles, dominant alleles, recessive alleles, homozygous individuals, heterozygous individuals, phenotypes, and genotypes.
Students will produce histograms using the DATA GRAPHS WIZARD.
In this activity, students understand the relationship between enzyme reaction rates and various environmental factors such as pH and temperature. They recognize the metabolic differences between endotherms and exotherms. They generate graphs by inputting reasonable data modeling enzyme activity rates.
The River of Life
In this activity, students compare human body mass with blood volume. They graph the data and build a regression model. They estimate their own blood volume and also predict volumes of blood for other animals.
Vernier - Heart Rate and Body Position
In this activity, students will use a Heart Rate Monitor to measure their heart rate while sitting, lying down, and standing. They will analyze the data collected to determine the effect of body position on heart rate.
In this activity, students observe and graph data about human fetal growth rates. Students build a regression model based on the data and compare values with those of other mammals. They also compare the data to non-mammal species.
Students will examine surface area and volume of cells and describe the relationship between surface area and volume of cells.
