Students examine fabric. In this Applied Science lesson plan, students look at the fibers of fabric through a microscope. Students compare and contrast a variety of fibers.

Students identify safety practices in the lab. In this lab safety instructional activity, students create a poster showing students working safely. They explain the importance of observing safety in the lab.

Students evaluate trash. In this Science lesson, students collect and weigh trash from their classrooms. Students categorize the trash and the corresponding weights, recording the information on a data sheet.

Students utilize a balance scale. In this applied science lesson, students compare the weights of two objects using an elementary balance scale. Students balance the scale with weights to find how heavy an object is.

Students make a prediction. In this applied science lesson, students guess the number of items in a jar. Students create a bar graph to show the predictions and the actual amounts.

This lesson provides students with a lab experience during which students construct a basic electric circuit and use it to explore dexterity skills. A chance to construct and operate a tool that extends a person's grasping ability and to...

Students use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.

In this acid and base worksheet, students use cabbage juice as an indicator to test the pH of various solutions. Students complete a table with the solution name, the color red and blue litmus paper turns, the color the cabbage juice...

In this mineral worksheet, students conduct mineral tests on unknown minerals and use the identification chart to determine which mineral they have tested. They test 5 unknown minerals and write the results of their tests in a chart.

Learners construct paper. In this applied Science lesson, students create paper using lint. Learners investigate the different fibers in their homes.

In this science worksheet, students incorporate their knowledge of math to solve the given problems about freezing points through conversions. They convert from unit to the other.  There are 10 questions.

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...
