Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Scholars take a journey through space with 16 eye-catching images. Along the way, learners read captions starting with the moon, then move onto asteroids, Mars, and Jupiter.

Take a walk on the wild side with a project about animal habitats. After kids observe a chosen animal in its home, they describe the animal's food and water sources, shelter, and how it raises its young. They then write a short fictional...

Step into a scientist's shoes to go online and discover the Florida Springs Expedition, and participate in two activities focusing on how humans impact the environment. The first activity asks scholars to summarize the six...

Students discover how much water they actually use and investigate the need for water conservation.

Students read an article and learn about building green.  For this environment lesson, students visit a website to learn about Mark Baker and Nonnie Chrystal.  Students write down the three events that led them to explore...

Pupils use the Internet to examine how to take care of a dog. They investigate how to bathe a dog, brush a dog, train a dog to do tricks, and feed a dog. They read a question and then click on the paw with the mouse in order to find the...

In this science activity worksheet, students will work in small groups to observe and record what happens to balloons after they are placed on flasks and immersed into a warm water bath and an ice water bath.

Third graders discuss the importance of personal hygiene and cleanliness. They examine why good oral hygiene is a significant part of maintaining a healthy body. They focus on the need for daily baths, hair care, and teeth cleaning. They...

Students read aloud a play script in a group to research the water cycle. They take the parts of raindrops. The amount of raindrops can be adjusted to fit group size.

In this owl cartoon activity, students color and examine a cartoon depicting a mother owl and her two baby owls who are taking a bath. No directions are given.

Third graders observe a frozen container filled with ice and discuss what happens when the ice sits out in the room. They practice measuring the mass and volume of the ice, watch as the frozen container is placed in a warm water bath to...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Learners explore basic needs through discovering that pets and people need very similar things. They will play matching games, sing songs, read books, and discuss the needs of people and animals.

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Did you know that cutting down your shower by one minute a day can save five gallons of water? Learn about water conservation with a science reading activity. After kids finish reading key terms and water-saving tips in a reading...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Enzymes: not just for breaking chemicals apart. Young biologists perform an experiment on potatoes. They first remove starch from potato extract. They then add the resulting liquid to samples of glucose-1-phosphate, glucose, maltose, and...

Kick-start a discussion of the importance of biodiversity with a colorful resource that touts the benefits of maintaining healthy ecosystems. The images stress the interdependence of all the elements of an ecosystem.
