Did You Know…? Four is the only number whose value is the same as the number of letters in its name.
Good afternoon,
Today students continued to explore mixtures in Science. We have been looking at mixtures of solids. Today we explored four different ways that we could separate solid mixtures: sieves, magnets, water, and air. When choosing which method to use when separating a mixture, it is important to think about the substances in the mixture. For example, a magnet would not be a good method unless one of the substances contained iron, nickel, or cobalt. Then we looked at mixtures of liquids. There are two methods that we explored to separate liquid mixtures: decantation and distillation. Decanting works well when the substances do not mix. For example, with a mixture of oil and water, decanting works well because the oil remains on the top. Today the students practiced decanting with some eye droppers. Distillation works well for solutions. For example, with a mixture of rubbing alcohol and water, distillation works well because they have different boiling points. When the rubbing alcohol and water mixture is heated, the rubbing alcohol evaporates first (at about 80°C). The gaseous rubbing alcohol can be collected and then cooled to return it to it’s liquid state. Tuesday we will be moving on to liquids and solids.
In Math today, students began converting fractions to decimals. We are able to convert fractions with a denominator of 10 or 100 into a decimal. If the denominator is 10, then the number goes in the tenth decimal place. For example, 5/10 = 0.5. If the denominator is 100, then the number goes in the hundredth decimal place. For example, 5/100 = 0.05 and 73/100 = 0.73. This is the easy part. It gets a little harder when we need to convert fractions that don’t have a denominator of 10 or 100, then we need to use equivalent fractions. For example 1/2 = 5/10 = 0.5 or 3/4 = 75/100 = 0.75. Today was only Day 1, so we don’t have homework, but students are encouraged to use their Mathletics to review.
