Curated OER
Moldy Jell-O
Students design an experiment to determine the best conditions for molds growth. In this biology instructional activity, students collect data for a week and analyze their findings. They create a presentation and share them with the class.
Curated OER
Electricity
Fourth graders experiment to find out how to light a bulb with simple materials. They make predictions if a light bulb set-up could work and gain knowledge to tell the difference between an open and closed circuit. They also figure out...
Curated OER
Float My Boat
Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..
Curated OER
Designing and Floating Boats
Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.
Curated OER
Heat from Light
Second graders explore solar energy. In this science lesson, 2nd graders use hand lenses to see that light energy can be converted to heat energy.
Curated OER
Solid Waste/Recycling
Young scholars see that when we throw away garbage, it usually ends up in a landfill. Landfill space is getting increasingly scarce, and every time we throw something away we throw with it the energy, the money, and the raw materials it...
Curated OER
Pinhole Viewer
Pupils make a pinhole viewer to demonstrate how it inverts light passing through it which produces inverted images.
Curated OER
Measuring the Diameter of the Sun
Students calculate and measure the diameter of the sun. They construct a meter stick instrument, calculate the diameter using a formula, and compare the measurement with the accepted scientific measurement.
Curated OER
Build an Electrophoresis Chamber
Students explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
Curated OER
Will it Float?
First graders discuss why some things sink and some float after dropping a variety of items into water.
Curated OER
Reflective Solar Cooker
Students build and use a reflective solar cooker to cook marshmallows.
Curated OER
Perpetual Motion
Students discuss movement of air currents and then experiment to create visible models of air currents. Students connect the model to weather patterns.
Curated OER
The Communications Lab
Students build and test a type of communication system called a parabolic-dish receiver. This type of system is exactly like radio telescopes, which are discussed in our song. They explain how signals are transmitted and captured with...
Curated OER
DNA Transformation of Bacteria - Red Colony
Students perform experiments with bacteria. They discover that genes can be transferred from one bacteria to another on the plasmid by a transformation. Over a two day period, students follow detailed instructions in order to observe...
Curated OER
Red, White, and Blue
Students explore the types of chemical reactions that can be made with household products. Through various inquires, students work to perform chemical reactions using common household substances and cleaners.
Curated OER
What Boat Designs Float the Best?
Fifth graders investigate buoyancy by conducting a science experiment. In this water properties lesson, 5th graders predict which of their different paper boat designs will float for the longest period. Students conduct the experiment...
Curated OER
Rock Cycle Activity
A few of the components of this lesson are not possible to carry out because the rock cycle diagram and challenge handouts are not included. Hopefully, you already have your own rock cycle diagram or worksheet to use as a concept...
Curated OER
WHY WE AREN'T FILTER FEEDERS
Young scholars describe three methods of obtaining food: scavenging, filter feeding, and hunting. They describe three methods of obtaining food: scavenging, filter feeding, hunting, and list at least two reasons why humans are not...
Curated OER
Wetlands/Watershed Model
Students make a model that will demonstrate the flow of surface water across the land in Texas and how materials that originate many miles away can end up in the wetland along the coast.
Curated OER
Energy in the Form of Calories
Pupils calculate the amount of food calories found in an individual peanut. In small groups, they set up the experiment so that a burning peanut will heat water above it. Using the temperature change and volume of the water they...
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
Curated OER
Rainbow Book
Students examine the different types of weather. They create illustrations of the type of weather to go into a class book. They are encouraged to examine the weather each day,
Curated OER
How Dense Are You?
Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
Curated OER
Projecting Spectra
Students use two methods to show and study the colors in the visible spectrum.
