Elementary school students can make posters to share science facts. This is especially effective for science topics that could use a little extra visual aid for explanation, such as the cycle of photosynthesis or the structure of the solar system. These posters can be drawn in groups and then hung up around the classroom so that they can be seen by students on a regular basis.
Flash cards can be used or made by elementary school students to share science facts with one another. This is especially good to learn new science vocabulary or to introduce and learn new science concepts. Words such as "evolution" or "gravity" can be written on one side of a card, with the definition of the term or concept on the opposite side of its matching term on the card. Have students quiz each other with the cards by asking partners to describe the term they are shown on one side of each card.
Presentations can help elementary students build teamwork and public speaking skills, as well as learn and share science facts. Give groups of students science topics to research, and then have them create simple and interactive presentations to share the facts with the other students in the class.
Elementary students can share science facts in the form of projects. Science fairs are a traditional method for students to learn science facts by conducting an experiment based on the scientific method. Have students share their project ideas, research and conclusions with judges and peers once the projects have been completed.
