In this hands-on experiment, students attempt to find out which holds more: an artificial kitchen sponge or a natural sea sponge. Students make measurements and analyze the results using a formula.
Students love it! They take it as a challenge to squeeze out as much water from the sponge as they can. In addition to hands-on science, they practice math skills by using a formula and calculating the average of their results.
Materials needed: artificial sponges, natural sponges, balance, funnel, graduated cylinder, water, cup or beaker, calculator
