Curated OER
What's on Your Plate?
Students demonstrate the path of food in the body. In this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
Curated OER
Porosity
Students investigate the concept of an aquifer and use a 2 liter bottle and other materials to conduct a simple lab experiment or demonstration. They calculate the volume of water that can be stored in the aquifer. The lab is used to...
Curated OER
Causal Patterns in Density Phenomena
Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
Curated OER
Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
Curated OER
Is There Really Life on Mars?
Students examine the work of scientists and determine how they test their theories.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
How to Design an Experiment
Students work together to develop and implement an experiment. They investigate the properties of nylon and construct a mobile of organic materials. They share their experiments with the class.

In this science worksheet, learners identify and locate vocabulary words related to various sciences. There are 20 words located in the word search.
Curated OER
How Much Do I Know About Water?
Sixth graders explore ways to analyze the properties of water and examine the chemistry of water. In this water lesson students work in groups and complete several activities.
Curated OER
How Much Do I Know About Water?
Sixth graders explore how water behaves on a penny. In this states of matter instructional activity, 6th graders observe water as they add drops to a penny. This instructional activity helps students apply the adhesive properties of...
Curated OER
Jell-O Optics
Students observe an activity with Jell-O to learn about optics. In this investigative lesson students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of light.
Curated OER
Heat Transfer and Pollution
Students perform computer simulations on air dispersion. In this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.
Curated OER
Grating Spectrometer
Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
