Distance, speed, and time graphs and calculations. Preparation for Physics exam at King's Academy. Explanation of distance calculations using constant speed and time, displacement, and
physical meaning of straight lines on various Distance vs Time graphs. Method of calculating average speed during a given time interval.

Volcanoes and Lava Rock. Video presentation and follow-up CoolMath exercise. Description of how volcanoes "erupt" and the secretion/ejection of hot lava rock and magmum. Navigating underground tunnels to avoid volcanic rocks/lava.

Today, Remington spent time on the MAPS diagnostic test. Then, he answered questions from the daily review, and we started our lesson on using strategies to practice addition facts.

Libby continued to work on yesterday's lesson on how to model putting together. She listened to word problems, identified and circled the important numerical information needed to solve the problem, wrote the corresponding number sentences, drew counters to model the addends, and found the sums.

This morning, Teddy completed the mid-chapter checkpoint to assess his understanding of the lessons so far on using pictures to add, model adding to, model putting together, and problem-solving. He did a great job answering the questions perfectly. Then, Teddy worked on a cut-and-paste enrichment activity on recognizing if addition equations with sums to 20 were true or false.

Human blood types are a good example of multiple allele genetics. Introduced terms to be used in blood typing. Transfusion, donor, recipient, antigen, antibody, agglutination, blood cells and plasma. Discuss how early blood transfusions were not very successful, resulting ion clots and death. Define and discuss the discovery of carbohydrate antigens on red blood cells which led to modern blood typing. Determine the antigen and antibody composition of all 4 major types of blood.

Microscope lab usage to show the effects of osmosis on plant cell osmotic pressure. Red onion skin cells were used because of their pigment being easily viewed. Membrane shrinkage and vacuole shirking was seen when the cells were placed in a hypertonic environment. Normal cells were viewed and diagrams in both environments drawn.

Ben used this period to research some data on his computer

Discuss why the particles in a colloid are prevented from settling out. Introduce the concept of polarity and charged atoms. Use diagrams to show how areas on the surface of the colloid molecule attract positive or negative charged areas of the dispersing medium. The layers repel each other and prevent settling out. Indicate why heating and stirring will interfere with the colloid particles and cause settling out. See diagrams to explain the Tyndall effect and the electrostatic layers.

Each Lower School artist got her/his own art notebook. I filled each with worksheets to learn and practice the art elements. Today, we learned about and drew different types of lines and geometric and organic shapes. Then we practiced shading forms. Tomorrow, we will create the color wheel. Each artist then shared what they learned and drew.
