Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Young scholars investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the...

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

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...

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.

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. 

For this density and buoyancy worksheet, students read about the equation to find density and practice finding the density of substances. They read about buoyancy and match 10 terms with their definitions related to density, buoyancy and...

In this chemistry learning exercise, students complete 12 short answer questions and problems on water vapor equilibrium. They calculate equilibrium concentrations of reactants and products.

In this solubility worksheet, students conduct an experiment to see how temperature effects the solubility of salt in water. Students record their data in a chart and then graph the results. Then students complete 2 short answer questions.

In this equilibrium worksheet, students perform a computer simulation on vapor pressure of water at different temperatures to answer 11 problem solving and short answer questions about the topic.

Learners demonstrate the three states of matter. In this matter lesson plan, students read Bartholomew and the Ooblek. Learners create "ooblek" and discuss what state of matter it is.

In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.

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 explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Students extract DNA from an onion using household equipment and supplies.

Learners explore gases. In this chemical energy activity, students will observer chemical reactions and infer a conclusion about reaction producing gasses.

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...
