Fourth graders measure cups, quarts, and liters.

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

Fourth graders are introduced and experiment with the concept of pi. Using this information, they discover the relationship between the circumference and diameter of circles. In groups, they practice measuring the circumference of...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

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...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

A resource rich in information—and nutrients. Learners create agars for the purpose of cell cultivation in Petri dishes. The lesson provides instructions on how to create agars for the cultivation of different microorganisms.

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

Students investigate mass-mass relationships in the lab. In this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. Students use the amount of...

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

n this geometric lesson plan, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

As your young learners develop into cooking enthusiasts, ensure their success in creating their next culinary masterpiece by preparing them to read and understand basic recipe terminology. 

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

In this density worksheet, learners read a selection on density and answer 10 questions using the information from the selection.

Young scholars investigate the properties of air through hands-on activities in conjunction with the demonstrations in a 3-2-1 Contact Video.

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

In this chemistry review worksheet, young scholars practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...
