Preparing the root tip samples is the most challenging part of the mitosis-viewing lab found here, but the directions help ensure you have everything you need. There is no worksheet included; however, there is a sample data table....

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...

Bored with frog and earthworm dissections? Had your fill of fetal pigs? Anatomy learners will be intrigued by the sheep's brain, and you will be prepared with guiding questions, extension activities, and pictures as they dissect one —...

How does sound travel in space? Fifth graders investigate this question with a science activity, in which they research the properties of sound. Schedule a lab visit for individual Internet research, or include the activity after you...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

It is unknown if cloud cover increases in response to carbon dioxide levels changing, helping climate change slow down, or if cloud cover decreases, allowing Earth to warm faster. Part four in the series of five lessons has classes...

Through inquiry and exploration, 4th graders will learn and understand the functions of open and closed circuits. They will break into 2 groups, define vocabulary, hypothesize how to light a bulb, then test their hypothesis 4 different...

Include a lab about alloys and magnets in your fourth grade science lesson. Young scientists read the necessary background knowledge about alloys, then choose which objects (a screw, a bell, scissors, or coins) will be attracted to...

Use a lab sheet on circuit diagrams in your electricity unit. Fifth graders draw two series circuits with diagrams, based on two examples. A science experiment prompts learners to use 3x5 cards to illustrate the way a series circuit works.

Investigate aspects of sustainable cities and relate them to where you live! A detailed lesson first investigates the definition of sustainability. Learners then explore human impact on the environment and social justice. Their final...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

During this lab activity, chemists discover the reactivities of chlorine, bromine, and iodine as examples of the halogens. They use a displacement reaction as a test by adding other compounds and observing for a color change. The lab...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Within the setting of a crime scene investigation, biochemistry beginners analyze organic compounds as a means of determining "Who dunnit." They use a brown paper test for lipids, glucose test strips and iodine to identify carbohydrates,...

Young scholars observe the effectiveness of detergents on breaking down proteins.  In this investigative lesson students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet. 

Pupils research the demands or limitations on Earth scientists. In groups, they design and build a model that would be useful to them in the lab or field. They share their model and their ideas behind it to the class and answer any...

Young scholars find the mass of the top quark. In this physics instructional activity, students create a vector diagram from a given set of data. They discuss their calculations and findings in class.

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...

Students examine worm habitats. In this animal habitats lesson, students participate in a lab activity that requires them to explore the adaptations that earthworms make to their environment.

Students examine the characteristics of craters. In this crater lesson, students discover how meteors form craters on planets and moons as they make their own craters and respond to observational questions regarding the...

While many chemicals are used in biology class, many pupils don't understand the material safety data sheets. The lesson explains each part and the importance of understanding the forms. Young scientists use safety equipment to ensure...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...
