Hi again class 🌷
This is the second part of the Natural Science proyect (which is the best). I´m going to assign some easy experiments that you have to do at home with simple materials.
- Observation / Question
- Research
- Hypothesize
- Experiment
- Collect data
- Analysis
- Conclusion
EXPERIMENT 1: WILL IT RUST?
Materials: Six different metal objects (needle, staples, pins, coins... whatever is made of metal)
Place all objects in DIFFERENT plastic glasses and add some water. Hypothesize about which ones will rust sooner, which ones will rust later and which ones won´t rust.
Collect data in your
scientific method template during a week (you can draw pictures and add text to it). Finaly review your hypothesis and check if you were right/wrong.
EXPERIMENT 2: WHICH SLICE?
Materials: An apple, a knife, six small glasses (plastic or glass), water, salt, sugar, honey, lemon, apple juice, coke (other type of soda if you don´t have coke).
Cut the apple in 8 different parts (similar size) place each slice into a glass and add the different liquids (Honey water/salt water/ sugar water/ plain water/ lemon water/soda/ apple juice).
Hypothesize about oxidation, will it get oxidate inside the liquids? will it get oxidate the same way?/ how do you think the features of each liquid will affect the apple? why?
Collect data in your
scientific method template during 3 days and review your hypothesis to check if you were right/wrong.
EXPERIMENT 3: CLEANING COINS
Materials: 5 cent coins (the dirtier the better), lemon, water, soy sauce, dish soap, vinegar, ketchup, coke, salt water, hot sauce, mustard and milk.
Put some of each substance in a bowl or cup enough to cover the coin, then allow it to sit for a time (45 minutes). Which substance do you think will clean the coins best? why?
Take out the products by using a napkin or some kitchen paper and see which coin is the cleanest.
Please, fill out one scientific method template for each experiment (LONG SENTENCES AND ELLABORATE WRITING PLEASE) and also take pictures of the procedures. During the week I´ll post some other experiments.
HAVE FUN 🐣
I MISS YOU SOOOOOOOOOOOOOO MUCH🌺
