Watch your marshmallows fly. The engaging STEM activity has groups create a catapult to launch marshmallows. After testing their prototypes, they consider improvements and redesign their catapults.

Students will conduct a lab on the oxidation of an apple. The students will learn that the oxidation process can be halted when lemon juice is applied to the flesh of an apple because the lemon juice contains vitamin C, an antioxidant....

Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Students engage in this, the third in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing...

Second graders sped the day exploring about balance by playing with and making balancing toys. They discover how varying the amount and position of mass affects the toys' balance. Pupils explore gravity and balance while playing with the...

Here is a cross-curricular ecology and technology instructional activity; your learners create spreadsheets depicting the location and number of groundhog dens in a local park. They research groundhogs and analyze data about where the...

Should your dog be watching tV? Read the article and then fill in the blanks by memory. Encourage a friendly debate: would you get DogTV for your beloved pet?

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

This lesson challenges students to make their own judgments about the safety of artificial sweeteners after hands-on study and Internet research, and to support those judgments with carefully considered evidence and reasoning.

Students explore ozone levels. They measure the concentrations of ground-level ozone in the atmosphere. Students observe changes in the concentrations of ozone over time. Students complete a data sheet to record ozone readings over a...

Students determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.

Eighth graders determine the location of specific features of the stimulated ocean floor. The features include the continental shelf, continental slope, an ocean trench, and a mid-oceaniz ridge.

Students explore how archaeologists make inferences from artifacts to explore what life was like in the past. In this archaeology lesson, students work in groups and make inferences about an imaginary household based on modern day...

Young scholars perform an experiment, collect, and analyze data of a rolling marble down a ramp. They report results after they complete their experiment. Students are assessed in science and writing.

Eighth graders examine two different types of tires and the effects of different factors on the amount of force needed to overcome sliding friction such as when the vehicle tries to stop.

Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...

Eighth graders investigate what would happen to the length of a rubber band as more and more rings were hung on it. They base their explanation on what they observed, and as they develop cognitive skills, they should be able to...

Students work in groups for up to three weeks to investigate the possibility of acid rain in your area and to investigate the damage that acid rain can do to buildings, monuments, and plants. Each group prepares a report to local...

Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...

High schoolers conduct Internet research on an autoimmune disease, and present the information in a PowerPoint presentation.

Students demonstrate force and motion by rolling a ball through a tube. For this motion lesson students explore what happens to the ball when it is rolled with other balls of various sizes, weights, and textures.

Students utilize technology for research. They research the potential causes of the sinking of the Hunley.

Students create their own baby pets based on the genes of the two parents.
