A pond water/hay infusion will be developed and observed. Student groups will add a range of acid and base solutions to look for changes.

In this activity students will use a mathematical model to study the process of radioactive decay in order to help understand how it can be used to determine the age of ancient earth materials.

Students will plan and conduct an experiment that investigates convection currents.

This is designed to be an introductory lesson to climate change. It covers the importance of the atmosphere, the basics of the "Greenhouse Effect" and an introduction to the human contribution to increased greenhouse gases.

Students model formation of an El Nino current in a pie pan.

Students will use a reading selection to compare the solar system to a neighborhood and do some writing, drawing and make comparisons to reinforce their knowledge about the rocky planets, gas giants and amount of matter in the solar system.

Students will calculate energy, frequency, or wavelength. After calculating, students graph their data and answer analysis questions.

Students will accurately prepare two solutions and use them to perform a Briggs-Raucher (starch-iodine) reaction.

Students will discover how the percent concentration for solutions is widely used in foods and medicines.

Students will add 4 chemicals to a beaker and observe the changes that take place. They will classify them as physical or chemical changes.

This lesson celebrates students's unique physical and personality traits. After reading and discussing the children's book The Crayon Box That Talked by Shane Derolf and Michael Letzig, students will share create their own artwork that...

This lesson plan includes directions for 5 different activities for making a variety of fossil types. The fossils included in all five activities are casts, petrification fossils, imprints and preserved fossils. The labs require a number...

Can you distinguish traits that are acquired from those which are inherited? Answer these online questions and find out.

Students examine soil samples for this activity and decide classify them according to whether they are sandy, silty or clay.

In this hands-on lesson, learners investigate the properties of different layers of soil.

Three activities are presented for fourth grade students to explore how thermometers work.

Students are put into groups for this activity, and given a soil sample which they sort into rock particles and organic material.

A good introduction to different types of fossils and how they form. There are also directions for making three different models of fossils.

In this engaging site, adaptations are defined and then a list of animals are provided along with adaptation-related questions to answer. Links to the animal sites are included.

For this activity, students create models in a tub or sandbox that simulate erosion caused by weathering.

A lesson for third graders in which they learn about the rotation of the Earth on its axis and how this movement creates day and night. They also examine the orbit of the moon about the Earth and the Earth's orbit around the sun.
