Making Hypotheses

Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson, they read a...

What do lemurs do best? They move! Lemurs like to jump, run, hop, and climb and it's your class's job to document seven fun lemur behaviors. The class starts by discussing why lemurs are considered primates, and then they isolate seven...

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

Students develop estimation skills by using real life situations. In this estimation lesson students collect data about their television watching habits. They make hypothesis about the number of hours they watch, how many commercials,...

Students explore natural resources by participating in an art creation activity. In this plant dye lesson, students identify the types of plants in nature that contain materials which can be used to paint or color clothing. Students...

Springs are amazing. Here, learners are presented with springs found in various everyday objects. They discuss which springs they think will have the most force, then test their hypothesis. This presentation has the start of a good idea...

If you want more pumpkin seeds, you should get a bigger pumpkin—right? Young harvesters use estimation skills to make a hypothesis about how many seeds they will find in a pumpkin before examining the real number inside.

Students practice how to approach a problem scientifically. They use their senses to make a detailed description of a natural object and to generate hypotheses about the identity and features of the object hidden within a box.

Students evaluate a false hypothesis by creating an experiment to analyze results. In this science lesson, students compose a hypothesis and explore aspects of the spring equinox. Students practice balancing an egg by designing their own...

Students observe a demonstration of how a thermometer functions. They apply the scientific method while determining which of three cups hold the coldest water. They write a hypothesis before conducting the experiment and gather data.
