Light Intensity Lab
Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.
Mascil Project
Circular Pave-Stones Backyard
Pack the instructional activity into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and...

Can Gravity Push Something Up?
How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...
Curated OER
Population Biology
High schoolers define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...
Curated OER
Water Pressure in the Ocean
Students compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...
Curated OER
Give Me a Tall Ship
Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.
Curated OER
Investigating Properties of Water: Temperature
Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...
Curated OER
Microwave Telescopes
Discovery of microwaves and other trivia starting this PowerPoint will help interest your class in the application and behavior of these radio waves. Great images to show real-life experiments and equipment help understanding of how the...
Curated OER
Name that metal!
Learners have to have had some experience with metals prior to using this worksheet. They are given five properties common to five different metals. They create or use a dichotomous key to identify the five mystery metals. Tip: This...
Curated OER
Examine Methods of Reporting Research Results
Learners analyze a research report and the list of components needed in a research report and then identify those components based on a set of standards using the scientific method. They collect data which can be used for a graphical...
Curated OER
Adaptation and Diversity on Sheffield Island
Written for an exploration of shoreline ecosystems on Sheffield Island, this gives ecology or marine biology buffs a hands-on experience. Using GPS or visual triangulation techniques, they lay transect lines on a high and a low energy...
Curated OER
Biomanipulation
Pupils explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.
Curated OER
Physical properties of matter
Sixth graders find the physical properties of matter. In this matter activity, 6th graders measure mass, volume, and density. Students are broken into 3 tiers with 3 different activities based on their understanding of mass and...
Curated OER
Vegetable Olympic Swimming: Will it Float?
Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...
Curated OER
Air Engine - Air Races
Students conduct an experiment about air volume, density, and pressure. In this air instructional activity, students discuss air, and how it moves. They make predictions about what will happen during the balloon and string experiment....
Curated OER
Force and Motion
Students experiment with force and motion. In this force and motion instructional activity, students test gravity using a variety of objects. Students rotate through a series of stations which use force, motion, friction, and inclines....
Curated OER
Evidence of Chemical Change
In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...
Royal Society of Chemistry
Polymers—Gifted and Talented Chemistry
Polymers are an important part of our day-to-day lives, but how much do your pupils know about them? Learn the basics and beyond in a series of activities designed to build skills in observation, planning, organic chemistry, and bonding.
Learning Games Lab
Fertilizing Chile
Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...
Curated OER
Unknown Liquids
Learners must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
Curated OER
Denser Sensor
Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...
