How Can You Demonstrate the Different Efficiencies of Different Light Bulbs?
Need a bright idea for an engaging lab? Watch your class light up as they explore the difference in efficiency between incandescent and LED bulbs! The resource makes use of simple materials and encourages learners to infer what's...
Curated OER
Food Safety Lab
Students determine the optimal living conditions for yeast and apply these results to microbes in food. In this microbiology lab lesson plan, students observe the reaction of yeast to elevated temperatures. They relate these results to...

The Gummy Worm Lab
Students participate in a lab experiment with gummy worms. In groups, they record the qualitative and quantitative observations during the lab. They use their senses to make inferences about the experiment and share them with the class.

Project 1
Young scholars are given a coin to observe and make inferences about. Using a worksheet, they make two columns to list their observations and inferences in an organized manner. They develop a hypothesis based on one of the inferences...

Red, Green, and Blue Mystery Liquids! Hypothesis or Inference?
Eighth graders are actively involved in the scientific method and inquiry as they form quick hypotheses based upon a teacher set of mystery liquids. They determine the need to make additional observations of the liquids.

Earth: Deposition and Lithification
Geology geniuses analyze sediment samples with a hand lens and sort according to physical characteristics. They also learn about the processes of cementation, compaction, and lithification within the rock cycle. The lesson plan is...
Curated OER
Mystery Boxes
Students make observations about Mystery Boxes that their teacher has made up and describes the motion of the object inside the box and hypothesizes it's shape based on their observations.
Curated OER
Can You See It, Touch It, Hear It?
Students develop and practice observational skills through lab activity.
Curated OER
Food Safety Lab
Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

The Heart Stopper
Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...
Curated OER
Reflecting on Reflectivity
Students plan and construct a "mini-lab" to measure the reflectivity of different earth surfaces. They measure reflectivity of materials, including ice, soil, rocks, etc., and then extrapolate from what they have learned to consider the...
Curated OER
Open-Ended Scientific Method Lab
Students inspect a given problem and come up with a hypothesis. In this investigative lesson students come up with a hypothesis for a problem, test each hypothesis and evaluate how successful each one was.

Molecular Movement in Water Part 1- Diffusion
Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...
Curated OER
Water Pressure Experiments
Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.
Curated OER
Bacterial growth
Students explore the exponential growth and decay of microbial populations in relation to the organism tolerance ranges in their environment, They observe the impact of changing variables which can affect microbial populations.
