There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

In this food energy worksheet, students review calories and how calories are determined. Students calculate how much thermal energy it would take to raise certain volumes of water a certain number of degrees. This worksheet has 3 word...

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Students find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Students are able to identify the components of the cardio-vascular system. They are able to describe the way the heart works to pump the blood. Students are able to explain the function of the cardio-vascular system. They are able to...

Students calculate the size of a molecule. In this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...

Eighth graders explore the term capacity and understand the word's meaning. They participate in several lab stations set up around the room in which they will estimate how many scoops it will take to fill the container. They then will...

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

Learners determine which types of garbage are biodegradable and which are nonbiodegradable. They practice measuring skills, hypothesizing, taking data, and writing a lab report. Students observe the relative biodegradability of metal,...

Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students investigate sound waves and they build audio speakers. In this audio speakers and sound lesson plan, students explore how to make quality audio speakers. As a team they build their own speakers to have clarity in sound, quality...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson plan, learners use scientific equipment to...

Students titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...

Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Using the San Francisco Children's Orchestra web site, first graders build listening and instrument identification skills. Each child wears head phones, listens to ID, and finds various instruments on the included worksheet. 

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

In this science worksheet, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.

Students study the concepts of motion, velocity, and acceleration through graphing their own movement using LoggerPro. They explain the difference between speed and velocity using the weather vane example. They discover the difference...

Students explore electrical resistance through various experiments. In this physics lesson, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.
