Altering a Plant Environment
Young scholars investigate what a controlled group is by creating an experiment. In this plant growth lesson, students identify the different parts of a plant and discuss what is needed for a plant to be successfully grown....
Curated OER
Fortune Teller Fish
Learners 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?
Learners 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
Students 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 lesson, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two variables.
Curated OER
See How They Grow: Plants And Their Parts
Students 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...
NASA
Heavy Lifting
Accept NASA's challenge to design heavy lifting vehicles. Groups of three design balloon-powered rockets to carry as much payload to the ceiling as possible. The teams are encouraged to launch several times while making...

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...
Curated OER
Mutations--Preexisting or Acquired?
Learners state the controls and variables of the Newcombe spread experiment. They state a hypothesis for the Newcombe spread experiment. Students distinguish between the characteristics of a preexisting mutations and those of an...
Curated OER
Electromagnets
Students improve their science skills by designing an experiment for the relationship between electricity and magnetism. For this science skills lesson, students discuss the scientific method and use the given materials to complete an...
Curated OER
Silicate Gardens
Students take digital pictures of their Silicate Gardens as an analysis of measurements of silicate tube growth. In this silicate measurements lesson, students download pictures of Silicate Gardens being grown on the International...
Curated OER
Lotic Environment
Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.
