How big is that carrot? Why one hand span, of course. As an exercise in measurement, individuals trace their hand in their science journal and search the school garden for one object the same size as the span between their thumb and...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Students explore temperature and use Celcius thermometers to measure and graph the temperature in the classroom daily. They estimate what they think the temperature might be and then find the actual temperature in the room.

Whales are all big, but some are larger than others! Kids will love sorting the 10 whale species by size at their desk (whale cut-outs provided). Next, use a whale rope to visualize how long each of these whales actually is. A large...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

In this nebula worksheet, students read about the Chandra X-ray Observatory that captured the given image of a pulsar and its nebula. Students solve 3 problems including using similar triangles and proportions to find the image width,...

Young scholars observe the inherited traits in earthworms and mealworms. In this organisms lesson, students view a live mealworm and earthworm on a tray and identify the body parts. Young scholars measure the worms and observe the...

Students examine the concept of radioactive dating. In this radioactive dating lesson plan, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Pupils experiment with heat. For this physical science lesson, students engage in hands-on activities to develop concepts related to heat. Pupils offer explanations for their observations using given vocabulary.

Is it nature or nurture? In an easily adaptable kinesthetic activity to introduce genetics, learners group themselves based on a variety of categories. They will quickly find that some characteristics are easy to put in order, while...

Learners explore weather instruments. In this weather lesson, students make rain gauges, anemometers, and barometers following the instructions given in the lesson. Learners set up a weather station using their instruments and record and...

Students research and demonstrate the temperatures of the Namibian Desert. They watch and discuss a video, conduct an experiment to demonstrate the desert temperatures, record their results in the form of a graph, and compare/contrast...

Third graders do an Internet search to find out about Galloping Gertie and what caused the bridge to fail.
