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 geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

In this thermometric titration activity, learners investigate the temperature changes when an acid neutralizes an alkali. High schoolers graph their results from the titration and draw the two best-fit lines on their graph. Where the...

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

In this geometry worksheet, students solve word problems having to do with lines, angles, shapes, area, perimeter, and more. Students complete 57 problems total.

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 explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

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.

Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...

For this quantitative analysis worksheet, students perform a lab to determine the amount of acetic acid in vinegar by doing a titration. They use an indicator phenolphthalein to determine the endpoint of the titration.

In this worksheet for making standard solutions, learners read about making a standard solution and perform the three background calculations necessary to make one. Students then make a solution by weighing a given substance, adding it...

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!

Two students are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of polygons....

In this power transmittance instructional activity, students read about sources that transmit power and are given a chart with the distance and the power transmitted by each device. Students determine the intensity in watts of the power...

In this composition of soil learning exercise, high schoolers study the make-up of soil by identifying the amount of air in the soil, the amount of water in the soil, the size of the mineral grains in the soil and the proportion of humus...

Students explore the three states of matter. For this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

In this density of pennies worksheet, student conduct an experiment to determine the metals used in the core of pennies made after 1983. High schoolers design their own experiments using a balance and graph paper to determine the density...

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

Learners explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

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 extract DNA from an onion using household equipment and supplies.

Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

In this estimating cell sizes activity, students read about the relationship between a cell's size and the rate of cell waste diffusion. Students solve 4 problems including writing the equation for the rate of waste exchange, finding the...
