I did this for fifth grade and got into the science fair and won 2nd place Question:What do liquids do to our bones? You will need 5 chicken bones Separate cups of coke vinegar milk lemon juice and water You will need one bone for each cup of liquid This project will take one month Every week you will take out each bone and examine the effect that liquid has on the bone. But dont throw out the cups I threw out the vinegar because it smelled horrible and the teacher deducted some points because of that. Hope I helped!
Explanation: I just took a test with the same question and it said I was correct plus it is on this website https://untamedscience.com/biology/biomes/coniferous-forest-biome/
