Curated OER
Density and Buoyancy Experimental Design
Pupils must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
Curated OER
Science: Objects That Rotate with Gravity
Students conduct experiments in gravity by rolling objects down an incline and determining which ones roll slower than others. As part of the experiment, they design objects which will roll the slowest. Using digital movie cameras or...

Watch That Plant Grow
Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.
Curated OER
Standard One: Lab Design and Appendix A Lab Skills
In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...
Curated OER
Rain Gardens for Controlling Excess Runoff
Students address the idea that human beings live within the world' ecosystems. They discuss how humans modify ecosystems as a result of population growth, technology, and consumption. Students discuss how the human destruction of...

The Miracle Fish: Learning to Design an Experiment
Students develop procedures to explore the behavior of fish. In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment.
Curated OER
Altering a Plant Environment
Learners investigate what a controlled group is by creating an experiment. In this plant growth instructional activity, students identify the different parts of a plant and discuss what is needed for a plant to be successfully...
Curated OER
Fortune Teller Fish
Middle schoolers demonstrate how to create and test a hypothesis. They design an experiment and set up a variable, experimental group and control group.
Curated OER
Using The Scientific Method
Students are given a problem or hypothesis, they can create a relevant experiment using the steps to the scientific method. They collect quantitative and qualitative observations in scientific experiments. Students identify the...
Curated OER
HOW IS PH DETERMINED?
Students estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.
Curated OER
Velocity and Acceleration
Twelfth graders look at local speed limits and traffic controls and see if they are reasonable. They plot the displacement and time to represent velocity, develop a plan for improving the current system, and organize experimental...
Curated OER
The Lift Equation
Learners use the FoilSim educational software program to complete an activity regarding lift. They solve a multivariable equation for each of the variables and apply the results to various problems in different situations.
Curated OER
Investigating the Biosphere With Planetary Models
Students create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to investigate in...
Curated OER
Shells and Subshells
Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...

Getting Started with the TI-Navigator™ System: What's My Rule?
Students explore linear relationships. In this sixth through eighth grade mathematics instructional activity, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two...
Curated OER
See How They Grow: Plants And Their Parts
Pupils discuss what plants require in order to grow, identify plant parts and their functions and discuss a video about plants. They conduct a controlled experiment with bean seeds and then record and observe the bean plants.
Curated OER
Targeting an Action
Students explore how the brain how the brain infers the position of a moving target. They investigate how the brain can fine-tune its motor control over the muscle groups that will perform the intended action. Students participate in a...

Newton's Apple
Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...
Chemistry Collective
Chemical Potential: Staircase Demonstration
It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.
Curated OER
How Many Drops?
Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...
