Students create a linking chain to demonstrate the food chain.  In this food chain instructional activity, students use the Internet to research sharks, including what they eat, and create a chain link with a picture of a...

In this weathering and wind worksheet, students simulate the effects of weathering by wind using 2 canisters, 2 types of sandpaper and 2 sugar cubes. Students swirl the sugar cubes inside the canisters lined with fine and course...

In this speed worksheet, students use dominoes to measure the average speed of rows falling over. Students make a line graph to show the relationship between the length of the domino row and the time. Students answer 8 questions about...

Learners explore the properties of matter.  In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...

Learners create a cartoon illustrating a lab demonstration. In this lab safety lesson, the teacher demonstrates a small methane explosion to demonstrate the importance of safety in a laboratory setting, then students work in groups to...

Here is a handy handout to give any science class as a guide to writing lab reports. It is a blank outline that you can have aspiring scientists fill out when they experiment, or imitate as they record their experiments in a lab journal....

Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...

Mini mycologists plan an experiment to determine what affects the growth of mold on gelatin. A list of available materials is provided, but the procedure needs to be designed by the lab group. A data table is also provided in...

Provide a mystery hair and a set of reference hair samples for middle school investigators to place on a slide and examine under a microscope. Materials and procedures are detailed on the first page, while a data table for drawing what...

How do humans get energy since they aren't mechanical and can't photosynthesize? Learners explore this question by relating potential energy in food to human energy levels. Scholars measure the change in mass and a change in...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome.
