This assessment resource checks for student understanding of population density and the factors that can cause fluctuations in population.
Students examine exponential and logistic growth, identify carrying capacity, distinguish between density-dependent and density-independent limiting factors, apply the population model to data sets, and determine carrying capacity from population data.
In this interactive module, students examine exponential and logistic growth, identify carrying capacity, distinguish between density-dependent and density-independent limiting factors, apply the population model to data sets, and determine carrying capacity from population data.
This assessment checks student mastery in interpreting motion graphs for constant speed and variable motion.
Students will connect the motion of an object to the corresponding position-time and velocity-time graphs to determine the velocity traveled during different time intervals.
In this lesson, students will connect the motion of an object to the corresponding position-time and velocity-time graphs to determine the velocity traveled during different time intervals.
This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models. Students will begin by following the path of a molecule of dye in water, create concentration gradients on either side of a cell membrane and watch the movement of substances in and out of a cell, and monitor the movement of oxygen into red blood cells with and without hemoglobin.
Students learn how the code on a strand of DNA can be used to make a protein. Each section of the tutorial includes quiz questions that can be answered and then printed at the end of the activity.
This assessment resource checks students' understanding of how motion can be represented on a graph.
Students will investigate motion along a straight line to differentiate stopping from moving with respect to a reference point. Note: This activity requires use of a motion sensor.
In this interactive module, students will investigate motion along a straight line to differentiate stopping from moving with respect to a reference point. Note: This activity requires use of a motion sensor.
Students will explore how a protein is made from an mRNA sequence.
This assessment resource checks for student understanding of how graphs illustrate motion and show a change in position over time. This assessment is meant to be used after students complete the interactive module found at http://smartgraphs-activities.concord.org/activities/194-motion-toward-and-away/student_preview
Students explore how motion in two opposite directions appear on a position-time graph. Note: This activity requires use of a motion sensor.
In this interactive module, students explore how motion in two opposite directions appear on a position-time graph. Note: This activity requires use of a motion sensor.
This assessment checks student understanding of how gravitational force affects the velocity of an object in freefall.
Students explore the effects of gravity on objects of different masses during free fall.
In this interactive lesson, students explore the effects of gravity on objects of different masses during free fall.
The High-Adventure Science Water module has five activities. In this module students will consider the question: will there be enough fresh water? In this guided activity, they will explore the distribution and uses of fresh water on Earth, explore models of porosity and permeability, run experiments with computational models, and hear from a hydrologist working on the same question. By the end of the module, students will be able to explain how humans can preserve supplies of fresh water for the future.
The High-Adventure Science Air Quality module has five activities. Students will explore the question, will the air be clean enough to breathe? They will be guided through the analysis of models and real-world data as they explore the interactions of factors that affect a region's air quality. By the end of the module, students will be able to predict the effect of human development on a region's air quality.
